CLWSC Implements Stage 1 Restrictions

CLWSC is implementing Stage 1 drought restrictions. Image: This Canyon Lake Shores Surface Water Treatment Plant features two ClariCone® clarifiers, each with the capacity to treat three million gallons of water a day. Within this primary treatment phase, the water is pre-chlorinated to help manage organic matter in the water and a coagulant is utilized to allow solid particles to cling to one another and sink to the bottom.

Stage 1 restriction water restrictions began Friday, June 1, for all residential and commercial customer accounts except those in the Rust Ranch and Whitmire Estates subdivisions, Canyon Lake Water Service Company (CLWSC) announced today on its website.

Drought Stage implementation is determined by threshold levels of consumption or supply, the level of Canyon Lake, or any combination of these.

Stage 1 Restrictions

Landscape watering (hose-end sprinkler and in-ground irrigation system) is limited to two days per week according to the last digit of your street address:

Even (0, 2, 4, 6, 8) – Monday and Thursday

Odd (1, 3, 5, 7, 9) – Tuesday and Friday

No address or more than one address – Monday and Friday.

CLWSC Drought Management Plan, which outlines more information about water rationing during drought, provides a strategy for the conservation of available water resources with an emphasis on maintaining available water supplies for the health and safety of the public, according to CLWSC’s website.

The plan facilitates CLWSC’s ability to provide continuous and adequate service to retail, bulk, and wholesale water customers in accordance with the requirements established by the Texas Commission on Environmental Quality (TCEQ) during emergency or drought conditions.

CLWSC infrastructure includes over 590 miles of pipes, three surface water treatment plants and over forty active wells located throughout the system. The company operates three wastewater treatment facilities in Comal County. A fourth is under construction.

    If we have to let our landscaping die during this drought, why are resident swimming pools allowed to run their water constantly to make up for evaporation? There has to be a limit.

  2. I am only at Canyon Lake on weekends. Can I water on Saturdays?
