Only Rain Down the Drain!
Posted: Mar 23, 2020 1:39pm

The U.S. Environmental Protection Agency (EPA) lists pet waste as a significant source of non-point pollution. Pet waste left on lawns, curbs, sidewalks, and streets can wash into local waterways during a rainstorm. Remember, stormwater currently receives no treatment. Water that flows into your stormwater drainage system goes directly into our bayous, rivers, and bays.

Please pick up after your pet!

WHCRWA Fee increase

Effective January 1st, 2019 the WHCRWA fee for ground-water pumpage will be increased to $2.95/1000 gallons while the surface-water fee will be increased to $3.35/1000 gallons.

What is the WHCRWA Fee?

The West Harris County Regional Water Authority (“WHCRWA”) is a governmental entity created by the Texas Legislature that assists in converting the region within its boundaries from using groundwater to predominantly surface water. In order to comply with the legislative mandate to reduce groundwater usage, Cimarron MUD (“the District”), along with other municipal utility districts in the area, are part of the Groundwater Reduction Plan ("GRP").


To comply with the groundwater reduction mandate, the WHCRWA is responsible for constructing the necessary water delivery infrastructure to deliver surface water to the areas within the WHCRWA. In order to design, construct, and operate the necessary infrastructure, the WHCRWA assesses fees to the well owners/municipal utility districts within the WHCRWA's boundaries based on the amount of water pumped by their wells or the amount of surface water received from the WHCRWA.

The WHCRWA assesses a fee for both groundwater and surface water usage by residents. This fee is used by the WHCRWA to fund projects and to meet legislatively-mandated surface water conversion goals. Find more information on the WHCRWA and their programs on their website,
