overview and project approach
Overview and Project Approach
  • Clinton is currently experiencing surface water supply shortages in their raw water source, Clinton Lake, and has been relying solely on their treated water allocation from the Foss Reservoir.
  • A long-term water study was conducted by Garver USA, LLC, and the City requested that Professional Engineering Consultants, P.A. (PEC) review the findings and develop recommendations.
  • Project Approach:
    • Revise population projection and water demand
    • Identify potential surface water sources
    • Identify potential ground water sources
    • Determine raw water source recommendations based on establishing a diverse water source portfolio
existing sources
Existing Sources
  • Clinton Lake
    • Good water quality
    • Very low water levels and small drainage basin
    • Water treatment plant capable of producing 2.5 MGD
    • Due to low lake levels, the water treatment plant has not been in operation since November 2011
  • Foss Reservoir
    • Poor water quality
    • Able to provide Clinton with 0.7 – 2.19 MGD
    • Water treatment plant in poor condition
  • Burns Flat Well Field
    • Unknown water quality
    • Located on the Elk City aquifer
    • City has water rights for approximately 0.2 MGD
    • Existing well field has not been used in 40 years
    • Low existing well yields

Clinton Lake – June 2012

Foss Reservoir – February 2011

potential sources purchasing water
Potential Sources - Purchasing Water
  • City of Clinton purchasing water from east Custer County
    • Known well fields currently using the aquifer as a source.
    • The amount of water provided to Clinton would depend on supplier’s demand and treatment capability.
    • Arsenic is found in some areas and would require treatment.
    • Purchasing water would require a pipeline.
  • Alternative 1
    • Construction of a transmission line from the Lugert-Altus Reservoir, and either augmenting Clinton Lake or directly treating it.
    • While the Lugert-Altus Reservoir is currently experiencing lower water levels, it has the largest drainage basin of the surface water options, and has the highest probability of recovery.
    • Requires construction of an intake structure, pipeline, easements, and upgrading of the water treatment plant.
  • Alternative 2
    • Obtain water rights and construct a well field in the Rush Springs aquifer.
    • Would require little treatment, and could be put directly into the distribution system.
    • Requires construction of a well field, transmission line and a disinfection station.
  • Alternative 3
    • Construction of a transmission line from the Lugert-Altus Reservoir and the well field at the Rush Springs aquifer.
    • Could fill Clinton Lake and treat with existing water treatment plant.
    • Rush Springs well field to provide a yield of approximately 1.3 MGD.
alternative cost estimates
Alternative Cost Estimates
  • Alternative 1
    • Total = $16,475,500.00
    • Does not include easements or upgrades to the water treatment plant.
  • Alternative 2
    • Minimum Yield Total = $12,575,000.00
    • Maximum Yield Total = $11,975,000.00
    • Does not include easements.
  • Alternative 3
    • Lugert-Altus Total = $16,475,500.00
    • Rush Springs Total = $11,975,000.00
    • Total = $28,450,500.00
    • Assuming maximum yield from well field.
    • Does not include easements.
    • Phased construction over several years.
      • Phase 1 is Burns Flat well field improvements.
      • Phase 2 is the Rush Springs well field – completed incrementally.
      • Phase 3 is the construction of the transmission line from the Lugert-Altus Reservoir.
water conservation recommendations
Water Conservation Recommendations
  • Clinton should begin a mandatory water conservation policy with the goal to limit the maximum daily demand to 2.19 MGD.
  • Residents of Clinton should be required to limit their water usage and minimize non-essential water usage.
  • The residents should be made active participants in water conservation with incentives to comply and fines for non-compliance.
  • The highest industrial users should explore water reuse options.
  • Water from irrigation wells with poor water quality should be utilized with point-of-use treatment.
raw water supply recommendations
Raw Water Supply Recommendations
  • Diverse raw water supply
    • Foss Reservoir
      • Continue to utilize their allotment
      • Only dependable water source available in the short term
    • Burns Flat Well Field
      • Investigate the existing well field on the Elk City aquifer for yield and water quality
      • Inspect, rehabilitate the wells, stand pipe and transmission lines
      • Phase 1 construction
        • Cost Estimate Range: $5,396,600.00 to $10,331,000.00
    • Rush Springs Well Field
      • Obtain water rights
      • Phase 2 construction – based on water demand, and to be completed incrementally
        • Cost Estimate Range: $11,975,000.00 to $12,575,000.00
    • Lugert-Altus Reservoir
      • Obtain water rights
      • Phase 3 construction
        • Cost Estimate $16,475,500.00
