Our Services

SPF Water Engineering has the practical experience, technical expertise, and personalized service required to deliver a successful water resource project.


We can help you find and develop a water supply to meet your needs. Water supply in the west has become increasingly challenging and complex, and SPF specializes in finding creative solutions that provide long-term, reliable water supplies for a range of purposes. Water rights are typically a first step to water supply projects and SPF has water right specialists to help you. We are working across the West on water supply issues and can help you secure water for your next project.

Water Reservoir/Aquifer Storage and Recovery Study

SPF was asked to evaluate ways in which water from different Moscow mountain reservoir sites could be used to augment or replace the city’s reliance on groundwater.  Specific objectives included the following:

  • Identify ways in which water from selected reservoir sites could be conveyed and integrated with Moscow’s municipal water system;
  • Prepare cost estimates for the water system alternatives; and
  • Evaluate these alternatives based on construction feasibility, projected order-of-magnitude cost, and general water-supply benefit.

SPF identified a number of innovative alternatives to consider for long-term water supply to the City. 

These water supply alternatives provide the City with options for future water system growth within a region of declining groundwater levels.

Regional Water Demand Study

The Idaho Water Resource Board retained SPF to determine the future water demands for the the Idaho portion of the Spokane Valley-Rathdrum Prairie Aquifer. The study looked at demand issues 50 years into the future. SPF considered historic population growth trends, estimated existing demands, reviewed climate projections, quantified water conservation potential, and projected future water demand for indoor domestic, municipal, commercial, industrial, and irrigation uses in the region.

With increasing competition for water, it has become critical to effectively manage and plan for future use. The ability to project demand 50 years into the future gives the Idaho Water Resource Board the necessary tools to prepare for future needs.

Confidential Client - Proposed Power Plant

SPF was the water supply engineer for a proposed nuclear energy power plant in the Pacific Northwest.  SPF completed preliminary design for a water supply pipeline on a fast-track schedule. The pipeline design presented multiple challenges due to the pressures created by the changing elevations over the various routes.  The river intake was designed in accordance with permitting requirements, resource agencies’ maximum velocity requirements for fish species, and the results of biological monitoring in the nearby river. SPF also provided guidance on water right acquisition and permitting strategies necessary to supply a water-intensive energy project.

Selecting the most cost-effective and environmentally sensitive pipeline route was a key component of the project.  Our client was able to significantly reduce project cost using SPF’s design of varied steel pipe connections and wall thicknesses as the pressures changed along the pipeline. 

Water Master Plan Update

SPF completed its first project for the City of Hailey in 2007. Since that time we have completed numerous water right projects, designed new wells and pump systems, helped to optimize the existing water system, completed a source of supply investigation, and prepared the most recent water master plan update.

The Master Plan lays out a detailed Capital Improvement Plan that the City can use for budgeting and planning future infrastructure projects.  In addition, the Master Plan work included an update to the City’s hydraulic model, which will be used regularly to check available fire flows and support growth and development in the City’s impact area.

Groundwater Supply Assessment

Alpenland, LLC retained SPF to conduct an assessment of groundwater resources available to support a future lodging and real estate development at Brundage Mountain Resort base area.  Groundwater at the site is obtained from a granitic aquifer with minimal historic development, leaving little historic data pertaining to groundwater resources at this site.  SPF’s investigation included the following:

  • A review of prior geologic reports and drillers’ reports of existing wells in the area.
  • Selection of locations for exploratory drilling based on field reconnaissance and a fracture trace analysis.
  • Permitting for test well construction. 
  • Supervision of the well drilling contractor during construction of three test wells. 
  • Test pumping of three test wells and one existing well. 
  • Evaluation of aquifer properties, potential well yields and anticipated sustainability of ground water supply.
  • Preparation and submittal of a water right application requesting appropriation of ground water for municipal use at the proposed development. 
  • Design and permitting of production wells and public water system facilities.

As with so many of SPF’s groundwater projects in support of new development, the study identified the availability of water to support the proposed development, identified infrastructure and associated costs that would be required to develop the groundwater source, and identified the water rights permitting and associated timeline needed to develop the resource.

Thompson Creek Mine

SPF has conducted a number of water supply and water right projects at the Thompson Creek Mine near Challis, Idaho.  Recent projects have included (1) design, permitting, and construction management of a replacement drinking water supply well and pump system, (2) design, permitting, and construction management for a replacement potable water storage tank, (3) surge protection and corrosion analysis for a high-pressure pipeline and pump station from the Salmon River, (4) water right consulting (including water right transfer applications, Snake River Basin Adjudication claim preparation and analysis, and water right beneficial use field exams), (5) water temperature monitoring assistance for surface water streams, (6) design and construction management of a large overflow protection tank that intercepted non-permitted discharges from reaching the Salmon River, and (7) a hydraulic analysis and pump design to deliver potable water to a facility that had a failing well.

These successful projects helped keep the mine infrastructure running smoothly and in compliance with regulatory requirements.

City of Nampa, Idaho

In response to unprecedented growth in recent years, SPF has worked closely with the City of Nampa on several projects to evaluate their current and future water right needs, determine alternatives to increase system capacity, provide water related information for property annexation decisions, clarify and organize their water right records, and conduct exploratory drilling to plan for future water supply wells. Projects successfully delivered to the City of Nampa have included new well permitting, design, and construction services; well rehabilitations; and domestic and irrigation water right master plans.

The projects have helped Nampa prepare for the future in supporting growth and development with an adequate water supply.

City of Middleton, Idaho

SPF has provided permitting, design and construction oversight on several water system facilities for the City of Middleton, including two full well facilities and one well facility upgrade.  These projects were completed on behalf of developers or the Middleton School District and conveyed to the city after construction was complete.  SPF worked closely with the City of Middleton and the city engineer on the facility designs and acceptance of the facilities during and after construction.

These projects have helped Middleton be prepared for the future – they have an excellent water supply that will be available for the long term to support the City as it grows.

City of Boise, Idaho

SPF (along with its predecessor firm Scanlan Engineering) has provided water engineering services for the City of Boise for more than twenty years.  Although the City does not operate a municipal water supply system (the potable water supply for the City is provided under franchise agreements by United Water Idaho and Capitol Water Corporation - also long-standing SPF clients), SPF has provided water engineering and water right consulting for the City’s geothermal system, park irrigation systems, and biosolids farm irrigation system.  In addition to design and construction services for more than 30 well and pump systems, SPF’s work for the Parks and Recreation Department has included annual reviews of approximately 80 well and pump systems each year since 1994.  The Parkwide Well and Pump Evaluation project has resulted in on-going documentation of the performance (static and pumping water levels, discharge pressures, pumping rates, etc.) of each of the park wells and pump systems.

Among other benefits, SPF’s services have enabled the city to anticipate and proactively address maintenance issues prior to a failure of a well, pump, or motor.


SPF provides long-term, ongoing water right consulting services to many government agencies, schools, churches, commercial, industrial, agricultural, and private use clients. This experience includes several years of investigating and cataloging existing water right portfolios and extensive technical support for contested claims in the Snake River Basin Adjudication.  The preparation of water right master planning reports helps SPF’s clients anticipate and prepare for future demands.  SPF staff have prepared and submitted hundreds of permit applications to develop new water rights and transfer applications to move or reconfigure existing water rights.  

We Routinely:

  • Prepare and submit permit and transfer applications
  • Conduct beneficial use field examinations
  • Research and evaluate existing water rights

In addition, we specialize in the analysis of complex water right issues and conflict resolution, and we often develop water rights strategies that focus on both the immediate and long-term goals of a project. Our staff is also well qualified to provide expert witness testimony and to provide litigation support.

At-Risk Water Rights Review

SPF was retained to review water rights owned by a confidential client in order to identify which rights were at risk of forfeiture. The rights were tied to a variety of properties throughout Idaho including meeting houses, recreational facilities, athletic fields, and agricultural lands. A GIS shapefile outlining the boundary of recorded use was created and compared to the legal descriptions of the water rights followed by an aerial photography examination. The final report provided action items for rights that were at risk of forfeiture and identified rights or water uses that required a transfer application or additional permitting.

SPF’s work helps this client clearly understand what they own and lays the groundwork for protecting and preserving their water rights into the future.

Coalition of Cities

Idaho Department of Water Resources issued an administrative order requiring curtailment of - or mitigation of depletive effects from - certain junior priority groundwater rights. Junior-priority rights listed in the order affected fourteen Idaho cities. These fourteen cities formed a Coalition of Cities, which retained SPF to assess vulnerability of curtailment to the current as well as potential future water delivery calls. SPF was tasked with first estimating Coalition cities’ consumptive and non-consumptive groundwater use under the existing water rights and secondly assessing vulnerability to curtailment under the existing and potential future delivery calls. The final phase of the project was to then provide any applicable recommendations associated with the water rights that would mitigate the potential for curtailment.

This work was essential in helping these small rural communities protect their water rights and avoid curtailment.

Developing a New Dairy

A southern Idaho farm owner needed to change the nature of use on portions of his existing groundwater rights from irrigation to commercial use to allow development of a new dairy operation. He also needed assistance in rebuilding and rehabilitating existing wells to assure an adequate water supply for his farming operation.  
During an initial review of the water rights, SPF discovered that the farm’s existing irrigation water rights were inaccurately decreed in the Snake River Basin Adjudication.  To fix the errors and provide flexibility for current and future farming operations, SPF prepared two transfer applications that were ultimately approved by the Idaho Department of Water Resources.  The first application corrected inaccuracies in the water right records, authorized the use of an integrated irrigation system, and authorized the addition of a new irrigation well.  The second application authorized new wells for commercial dairy water supply.
Following transfer application approval, SPF provided design services for the new irrigation well.  Upon successful completion of the new well, SPF provided consulting services for rehabilitation of several other irrigation wells on the farm.

SPF’s work helped this farmer protect existing water rights and develop a needed additional water supply.

Water Rights Master Plan

SPF prepared a detailed review of water rights used in the City of Nampa’s existing domestic municipal supply system.  The information was developed through research of records from the Idaho Department of Water Resources and the City of Nampa, meetings and correspondence with city staff, and the city’s water system master plan.

The report documents the City’s existing water rights associated with the potable groundwater supply wells, including applications for permits, claims, licenses, and decrees. It also considers the City’s current and projected future water demands and presents a strategy to maintain a comprehensive water right portfolio through the year 2030.

SPF’s work supports Nampa’s plans for growth and development into the future by showing the way to a reliable long-term water supply strategy.


We approach the design of water system facilities with the goal of providing both a functional and operator-friendly design, and we always consider the operation of the entire system, not just an individual facility, in our designs.  SPF works closely with our clients to design storage tanks, pump stations, pipelines, well houses, and water treatment facilities that meet or exceed expectations.  We have designed water system facilities across the West and look forward to helping you with your next project.

garden city

Garden City, Idaho

SPF has served as Garden City’s on-call water system engineering firm since 2005.

SPF’s work has supported Garden City’s substantial investment in improving water system infrastructure over the last decade.  The completed water system upgrades enable additional development within Garden City and provide improved water quality.

Suncor Development Company

When SunCor Development Company came to Idaho to develop a large planned community, located approximately 6 miles northwest of Boise, they were immediately faced with challenging water resource issues.

SunCor hired SPF to conceptualize and implement a plan to bring water service to the Avimor development.  SPF did extensive hydrogeologic and water rights investigations in the area. When inadequate locally available water sources were found, SPF conceptualized, permitted, and successfully designed approximately 5 miles of 16-inch diameter high-pressure transmission main, a 2,000-gpm in-line booster pump station, and a 600,000-gallon welded steel reservoir in order to transmit water from United Water’s existing water facilities to Avimor.  An aquifer suitable for aquifer storage and recovery (ASR) was identified on the Avimor property, and upon implementation of ASR, water can be stored and conveyed from Avimor back to United Water’s main service level in Boise. 

SPF’s work at Avimor showcases our ability to find water supplies in new, challenging areas.  If existing ground or surface water is not available, SPF can develop strategies to support growth in other, creative ways.

Micron Water Treatment

Micron Technology requires a continuous source of high quality water for their semiconductor manufacturing facility at the Federal Way campus in Boise, Idaho. To meet these needs, SPF’s engineers worked with Micron on the planning, design, and construction of an innovative 1 mgd membrane filtration plant and aquifer storage and recovery project. SPF worked with Micron to expand the facility to 2 mgd, with an ultimate capacity of 4 mgd. SPF’s engineers handled the water rights acquisition, well design, aquifer modeling, and water treatment plant design for the system.  Two stages of membrane treatment are used to reduce rejected water to less than 1 percent of the total flow. The treated water is injected into the aquifer via a 1,215 feet deep well, and later recovered through existing production wells located ¼ to ½ mile away. The temperature and chemistry of injected water stabilizes along the flow path from injection to recovery.

The project won the ASCE Southern Idaho Section and the Pacific Northwest Regional Outstanding Civil Engineering Achievement Award and competed in the national competition.

A ground breaking project in many aspects, this was the first Aquifer Storage and Recovery project of its kind permitted in Idaho, and was one of the first membrane water treatment projects in Idaho as well. At the time of construction, the project gave Micron the ability to expand operations at their Boise plant without being limited by water supply.

Arrowrock Ranch Subdivision

SPF developed the water system concept, and completed the design, permitting, and construction management services for this new 100-home development.  A water supply study identified local hydrogeologic characteristics and confirmed that groundwater could supply the development.  SPF assisted the Owner in obtaining new water rights for domestic and fire protection uses, and transferring existing irrigation water rights for irrigation uses within the new development.  Because high capacity wells could be obtained in the area, no storage tank / booster pump station was needed to provide fire flows, saving money on initial capital costs.  Two wells that provide domestic, irrigation, and fire flow were constructed.  The two wells contain three pumps, another cost saving measure.   A common well house is used for both wells.  The system is automated and runs with minimal oversight.  The new Public Water System was permitted through the Idaho Department of Environmental Quality, and also set up through the Idaho Public Utilities Commission.

This project highlights one of SPF’s strength in developing new Public Water Supply Systems – determining where the water will come from, the infrastructure needed, the water right strategy and permitting, and design and construction oversight of the system.


We approach our clients’ wastewater management challenges with the same holistic approach as our other services.  Whether our client’s objective is wastewater disposal, or recovery of valuable nutrients, energy, or water prior to disposal, our wastewater solutions are focused on our clients’ success.  We have provided wastewater solutions for small, rural systems and to some of the region’s largest facilities. Our wastewater clients include food and beverage, high-tech, and mining industries; and local, state and federal government agencies.  

Confidential Industrial Client

SPF assisted an international industrial beverage processing client with design and permitting for a wastewater treatment and algae resource recovery system. SPF also assisted this client with pilot testing planning, design, construction services, operation, and reporting of a similar resource recovery system configured as a membrane bioreactor for very low effluent BOD and TSS concentrations and as pretreatment for groundwater replenishment.

The client is saving millions of dollars in industrial pretreatment fees each year and is supplementing its income with a revenue stream from the sale of a valuable byproduct.

Greenleaf Collection System, Wastewater Treatment Plant, and Land Application Project

SPF led the design team on this new new wastewater treatment plant for the City of Greenleaf, Idaho.  The treatment plant includes two oxidation ditches, two clarification tanks, and numerous buildings to provide complete sewage treatment.  SPF also engineered a new wastewater collection system for the city and provided construction oversight for the entire project. A combined land application and river discharge approach is used to dispose of treated effluent.

The team’s effort on this project means that capital and ongoing operating costs are minimized and Boise River water quality is improved.  

National Guard ORTC and MATES Wastewater Project

In order to support growth of an existing Guard training facility between Boise and Mountain Home, SPF prepared a Wastewater Treatment and Disposal Facility Plan, Preliminary Engineering Report, and Final Design documents. The Guard facility has an existing wastewater lagoon treatment system with subsurface discharge. The wastewater facility was originally constructed in the early 1990s, but not permitted by any regulatory agency. To allow expansion of the training site, a full capacity and treatment assessment was required.

Improvements included adding new control and monitoring equipment throughout the system to track influent and effluent pumping rates and volumes; relining one of the existing lagoons that did not pass the IDEQ required seepage test; two new submersible effluent discharge pump stations, two new subsurface disposal systems; a new influent lift station, and an additional lined treatment lagoon. Due to the large size requirement and challenging soil conditions, drip systems with automated controls were utilized. As part of this project, SPF also provided design of water system improvements, including a new well, storage tank, and booster station providing domestic and fire protection for the facilities.

Sufficient capacity was provided for highly variable loading scenarios, which enables the guard to mobilize large numbers of soldiers for training and to sustain its mission readiness.

McCall Lift Station 7

SPF designed a replacement for an over-capacity lift station located within 50 feet of the North Fork of the Payette River, very close to the 100-year flood plain. The new lift station is designed to collect and convey 1,200 gpm of sewage flow across the River. Site constraints include the river crossing with two pipelines, deep excavation (approximately 35 feet) near the river, a nearby fish hatchery water supply pipeline that must be protected and maintained in continuous service, and a required small construction footprint. 

The client is able to serve a growing part of the city, despite challenging topographic and environmental constraints.

Meridian Wastewater Resource Recovery Facility

Chemical Feed Building
The chemical feed building was necessary to support the chemical dosing needs for the secondary and tertiary treatment processes at Meridian’s Wastewater Resource Recovery Facility. The project involved design of a building to store and supply chemicals which condition secondary effluent, maximize phosphorus removal using the existing tertiary filters, and improve turbidity for recycled water use.

Dewatered Solids Screw Auger and Drying Bed Improvements
SPF served as the Prime Consultant for the sludge drying bed and dewatered biosolids screw auger improvements at Meridian’s Wastewater Resource Recovery Facility. The project included the replacement of an old belt conveyor with a new screw auger and the complete reconstruction of the drying beds. The reconstructed drying beds feature a 7-inch thick reinforced concrete slab and a 6-foot high concrete containment wall. The project design allowed for continuous operation of the biosolids dewatering facility throughout construction and was extremely successful in meeting the city’s goal of improving drainage and providing a durable surface and containment wall for loading operations.

The client received value for its engineering fees as these projects were completed with minimal changes and design fees were below average percentage of construction cost.

twenty mile

Twenty Mile South Farm

Twenty Mile South Farm in Boise, Idaho is a 3600-acre irrigated farm for reuse of biosolids generated by the City of Boise’s municipal wastewater treatment plant.  The SPF team has been instrumental in development and maintenance of irrigation at the farm.  This work has included (1) design and equipping of two new high capacity wells with 400-hp and 500-hp variable speed pumps and a combined capacity of nearly 6,000 gpm, (2) creation of an irrigation water supply master plan, (3) on-call consulting for water supply issues, (4) development of an annual well and pump maintenance program, and (5) water right consulting.

SPF’s work has been instrumental in helping farm staff keep this large pump system running efficiently. 

Confidential Agribusiness

SPF has provided detailed irrigation system design on approximately 5,000 acres at two sites in southwest Idaho, for a large agribusiness.  Irrigation is primarily from center pivot systems.  At one site, wastewater is reused requiring Idaho Department of Environmental Quality review and approval of all system plans.  At the other site, SPF provided hydraulic analysis to optimize pressures and efficiency for a sprinkler system with more than 100 feet of elevation change.

SPF has helped this client keep their irrigation systems as efficient as possible, saving dollars and enabling the continued functions of their systems.

Church Irrigation Facilities

Water supply was needed for domestic, fire protection, and irrigation purposes for a new church in Canyon County, Idaho.   SPF was hired to provide the appropriate water right application filing, the design and construction management of one irrigation well and one high-capacity fire protection well, as well as the permitting and design of associated pumping systems. 

SPF was able to target a higher-quality, lower-capacity aquifer the church could develop for domestic purposes and then target a lower-quality, higher-capacity aquifer to develop for fire protection purposes. This approach avoided costly and high-maintenance water treatment options.

This new water system was efficiently developed to keep costs to a minimum. 

Nampa Pressurized Irrigation

The City of Nampa has almost 100 non-potable pumping facilities (surface water and groundwater supplies) that furnish pressurized irrigation water throughout the community. This project required identifying city-wide irrigation demand fluctuations, quantifying capacity of existing water deliveries (both surface and groundwater), and identifying means to improve and optimize the efficiency and functionality of the non-potable water system. 

Well and pump systems were evaluated over the course of two irrigation seasons.  SPF’s portable ultrasonic flow meter was used to log flow rates at selected wells for one-week periods, and also for calibration of installed flow meters.   Based on this information, SPF was able to determine irrigation demand schedules and efficiencies of irrigation pumping systems.  Recommendations were provided for improvements in facilities and operations.

SPF’s work has helped the City keep their irrigation system operating as smoothly as possible, in support of their long-term water right goals and approach of maximizing supplies provided from their irrigation system while minimizing the amount of irrigation water provided from the potable water system.

School Districts

SPF has provided water supply consulting on numerous projects for the Boise, West Ada, Caldwell, Vallivue, Garden Valley, Middleton, Nampa, Marsing, Bruneau-Grandview, and Blaine County School Districts, along with projects for numerous private schools.  Projects have included well designs, well and surface water pumping systems, pump system upgrades, repairs, and replacements; water treatment systems; alternative water source studies; and water right consulting.

Many schools run their own water supply systems for potable, irrigation water supplies, or both.  SPF has been proud to support schools in these efforts, as these systems often save the schools substantial amounts of money over purchasing water from municipal suppliers.


SPF’s building and site civil experience includes all types of site development, utility infrastructure, and roadway projects.  Our engineers have designed and provided construction oversight for numerous site development projects, thousands of parking spaces, and countless miles of roadway and utility infrastructure.  We are intimately familiar with land use issues, entitlements, and permitting.

Meridian Wastewater Administration Building and Laboratory Expansion

SPF led the multi-disciplinary design team and performed site civil design services for a new 3-story, 12,400 square foot administration building, a 6,600 square foot laboratory expansion, and a 3,600 square foot remodel of the existing administration building to be a new operations control center at the City of Meridian Wastewater Resource Recovery Facility.  The buildings were constructed under a construction manager as advisor delivery model.

The City is left with administration and laboratory facilities which provides space for the wastewater department’s next generation administration, operations, and laboratory needs.  Also, the buildings were constructed with a very low overall change order percentage, demonstrating quality design and communication with the construction manager.

Meadowlake Village

SPF provided site civil engineering services for Touchmark Development’s 120-acre Meadowlake Village Retirement Community located in Meridian, Idaho. SPF completed the civil engineering construction plans for the new 28,000 S.F. Targhee Lodge Homes building and new 90,000 S.F. Memory Care facility, both built adjacent to the Grand Lodge in the heart of the Meadowlake Community.

SPF’s general civil engineering services for these projects supported the quick and efficient construction timeframe needed for these facilities.

Micron Lehi Owner’s Representative

Micron Technology, Inc. currently owns approximately 2,000 acres of developable property in Lehi, Utah which is fronted by Utah Department of Transportation’s (UDOT) SR-92 highway.  UDOT undertook a very large highway expansion that required the condemnation of Micron property and threatened to eliminate access to SR-92 and Lehi City utilities.  Since October of 2009, SPF has taken the lead to ensure Micron retains vital vehicle and utility access to their property.  SPF makes routine site visits to Lehi, Utah, attends meetings for Micron, and provides support to the multiple efforts that have been necessitated due to the SR-92 project.  SPF continues to work and coordinate with Lehi City, Highland City, UDOT, Provo River Water Users Association, special utility districts, UDOT’s design build contractor, neighboring property owners, IM Flash Technology, and consultants.  

SPF’s efforts have resulted in maintaining existing transportation access points, maintaining the ability to access new transportation access points, maintaining access to existing sewer, water, and storm drain facilities, and maintaining the ability to access future sewer, water, and storm drain facilities for Micron’s property north of SR-92.

Confidential Client - Wastewater Reuse Facility

SPF has provided quarterly water level monitoring and water quality sampling for a wastewater reuse facility near Caldwell Idaho since 2004. Prior to 2004, this work was conducted by SPF's predecessor firm, Scanlan Engineering, continuously since 1995, and intermittently by Terry Scanlan since 1986.  Over the past 25 years, Terry and the SPF team have collected more than 2,000 groundwater samples, and have maintained a database of sample results.  For this project we currently sample a total of 36 monitoring wells on a quarterly basis. Reports of findings, including a summary of field and laboratory results, individual laboratory reports, QA/QC sample results, and aerial-photo-based groundwater contour maps are sent to the client following each sampling event.   The sample results and contour maps are provided to the Department of Environmental Quality on an annual basis. 

SPF’s work provides ongoing support to the client in meeting regulatory requirements, and feedback on the efficiency with which their systems are running.

Sun Valley Company

The Sun Valley Company hired SPF in 2006 to collect water quality samples from a well operated as part of their snow-making process at the ski resort.  This sampling is conducted to comply with an agreement with the Department of Environmental Quality.  SPF has performed this sampling annually since 2006.  Water quality parameters are measured in the field and samples are also collected for laboratory analysis.  A summary report is prepared following the sampling event.

SPF’s work supports the ski areas’ operations and their goal of providing a great skiing experience for their customers.

Avimor Homeowners Association

SunCor Idaho, the developers of Avimor Planned Community, agreed to a 10-year water-level monitoring program as part of an agreement with the North Ada County Foothills Association (NACFA). SPF has provided the agreed upon water-level monitoring, which consists of semi-annual water level measurements of 15 wells in the area. Eight of these wells belong to members of NACFA and the other seven are owned by Avimor. An annual summary report is prepared. 

SPF also conducts water level monitoring and ground water quality sampling from seven shallow monitoring wells and surface water quality sampling from four locations on the Avimor property.  This work satisfies monitoring requirements outlined in the Avimor Wastewater Reuse Permit.

SPF’s work supports Avimor’s ongoing operations and keeps them in compliance with regulatory requirements.

Choosing the right tools to analyze a problem is critical to the success of a modeling project. Oftentimes, a simple analytical or statistical model is sufficient to answer the question at hand. We often use simple, low-cost models to address regulatory or other concerns, without the need for more complex models. When faced with a more complex problem or challenge, a numerical computer model might be the most suitable tool. SPF uses these numerical models to analyze complex groundwater, surface water, aquifer, water system and wastewater system flow processes.

Some uses for models include the following:

  • Assess Current or potential future pumping impacts on groundwater
  • Analyze water right issues
  • Analyze distribution and collection systems for the appropriate capacity, and verify the impacts of proposed improvement projects

Our staff has experience constructing models to simulate flow on local and regional scales. We have used models to evaluate water right matters in the Treasure Valley and Eastern Snake River Plain to assess potential impacts of industrial water re-use, to simulate geothermal flow in the Boise Front geothermal aquifer, and to determine channel and culvert capacities. We have created and run hydraulic models for both water and sewer systems.
