Water Conservation

water restrictions

Residents of the City of Casper and all areas served by the Central Wyoming Regional Water System (RWS) are being asked to limit irrigation to 2 days.  Irrigators should water for no more than 20 minutes per zone, although some soils will need less water.  

The RWS request is linked to an equipment failure at a major water treatment chemical manufacturing plant, which could impact the ability of the facility to treat enough water to meet high summer demand. The chemical enables the facility to treat an additional 18 million gallons of water per day needed to meet the water demand from irrigating lawns during the summer months.  RWS expects chemical supply disruption to continue through midAugust.

The chemical in short supply is used to treat the surface water drawn from the North Platte River.  The Central Wyoming Regional Water System has two sources of water groundwater and the North Platte River. During the summer months, 70% of the water produced is drawn from the North Platte River with the remaining 30% provided by the ground water source. Groundwater is pumped from the North Platte River alluvial aquifer via 29 wells.

The City of Casper is reducing irrigation at its parks and other properties that are on city water to help conserve.  The request does not apply to irrigation systems on well or raw water.  The City has several facilities that use wells or "raw" water for irrigation, those include:
Fort Caspar
Paradise Valley Park
Casper Municipal Golf Course
Crossroads Park (ballfields and Adventure playground)
Mike Lansing Field
Ford Wyoming Center
the Skeet Range
the Air Modelers Facility
Wells Park
The North Casper Athletic Complex (soccer, softball, & baseball fields)
The Field of Dreams Baseball Complex.

Water conservation practices from landscaping experts include:

  • Water no more than two times per week for no more than 20 minutes per zone.
  • Water lawns and gardens during cooler hours. Refrain from watering from 10 am to 5 pm.  Watering during cooler hours means that you will lose less water to evaporation and more of it will go to the plants.
  • Avoid watering during windy conditions. 
  • Repair leaking sprinkler systems.
  • For trees, water with a hose and move the hose slowly around the trunk.  New trees should be watered 2-3 times per week and established trees watered 2-3 times per month.  For more information, see this pdf guide on Tree and shrub care during a drought.  
  • Don’t allow water to pool or run along gutters or alleyways
  • Use a hose nozzle with an automatic shut off when washing vehicles
  • Use a broom rather than water to clean hard surfaces such as sidewalks and driveways
