During the May 21 Rowlett City Council meeting the council considered an ordinance adopting the 2019 Water Conservation Plan and the 2019 Water Resource and Emergency Management Plan – jointly the Water Management Plan – and authorizing the mayor to execute the necessary documents.
Jeremy Rice, hydrologist for Freese and Nichols, said this is required by the Texas Commission on Environmental Quality (TCEQ) through the Texas Administrative Code, Texas Water Development Board (TWDB); it’s required by contract as a wholesale water customer of the North Texas Municipal Water District (NTMWD), and must be consistent with NTMWD plan, and must be updated every five years due to TCEQ and TWDB by June 5.
Goals in the plan include reducing consumption, reducing loss, increase efficiency, encourage efficient outdoor use, maximize the level of recycling and reuse, and extend supplies.
“Part of what the documents outline are five- and 10-year goals for per capita use,” Rice said.
The city’s gallons per capita daily (GPCD) average from 2009-2018 was 119; the goal for 2024 and 2029 is to remain at 119.
The residential GPCD average for 2009-2018 was 87; the goal for 2024 is 85 and 83 for 2029.
The water loss GPCD average for 2009-2018 was 12; with a 2024 and 2029 goal of less than 13.
The water loss percentage for 2009-2018 was 9 percent; the goal for 2024 and 2029 is to have it less than 12 percent.
The other document discussed for approval that night was the drought contingency plan.
“The drought contingency plan deals with periods of emergency or water shortages, where the lakes have gone down and water supplies are diminished,” Rice said. “The goals of this plan are to reduce water use temporarily so the emergency is able to handle, pipes are to be fixed, or the water supply recovers due to rainfall.”
The council unanimously approved the 2019 Water Conservation Plan and the 2019 Water Resource and Emergency Management Plan with revisions to the total water conservation goal to equate the current conversation levels.
