This fee is set by WHCRWA and may change.  In order to comply with the requirements of the Harris-Galveston Subsidence District, the WHCRWA seeks to reduce groundwater withdrawals and transition to using more surface water as a method of minimizing subsidence and helping the aquifers recharge.  WHCRWA supplies treated surface water obtained from the City of Houston to certain MUDs.  MUDs receiving surface water from the WHCRWA pay the surface water fee.  Well owners within the WHCRWA’s boundaries that pump groundwater from permitted wells (including MUDs) pay the groundwater fee.  For more information about the WHCRWA, please visit www.whcrwa.com.
