GRP Division – Located at the Lake Conroe Dam, the Groundwater Reduction Plan Division is responsible for implementing a countywide program that will meet the requirements of the Lone Star Groundwater Conservation District to substantially reduce future groundwater usage from the Gulf Coast Aquifer by ensuring a reliable, long-term diversified portfolio of alternative water supply sources for all of Montgomery County.  The GRP Division will utilize a number of alternative water strategies, including conservation, reuse of treated wastewater effluent, groundwater from all Gulf Coast Aquifers including the Catahoula Aquifer (and possibly other remote groundwater sources), and surface water from Lake Conroe (and possibly other surface water sources).  Phase 1 of the GRP strategy will include the design, construction, operation, maintenance, and administration of a water treatment plant and transmission lines that will treat raw surface water to meet or exceed drinking water standards, and then deliver treated water to cities and utilities within Montgomery County in the most cost-effective manner.
