The North Texas Municipal Water District (NTMWD) began providing high-quality potable water supply in 1956 to approximately 32,000 citizens with a treatment plant capable of delivering 20 million gallons per day (MGD). Charged to meet the immediate and future potable water needs of the region served, the NTMWD currently meets the daily needs of over 1.6 million people with a treatment plant capacity of 770 MGD.

The NTMWD utilizes surface water supplies from Lavon Lake, Lake Texoma, Jim Chapman Lake, Lake Tawakoni, and Lake Bonham. Water is also supplied by the East Fork Raw Water Supply Project, commonly known as the “Wetland”.

During the spring and summer of 2007, the North Texas area received above-average rainfall bringing an end to a two-year drought. As a result, the NTMWD began the 2007-08 Water Year (August 2007-July 2008), with raw water supplies at normal levels for the time frame.

Water consumption typically follows a pattern of higher use during years of low rainfall with warmer than normal temperatures and lower water use during years with aboveaverage rainfall. The NTMWD treated and delivered 90.3 billion gallons of water during the 2007-08 Water Year, a 16 percent increase as compared to 77.5 billion gallons delivered during the 2006-07 Water Year. During the 2006-07 Water Year, consumption was reduced through mandatory measures for the different stages of the drought contingency plan that were implemented during the drought period.

During the 2007-08 Operations Year (October 2007-September 2008), Water System construction contracts totaled over $462 million. Major projects focused on the development of additional raw water supplies to meet the increasing needsfor the NTMWD service area. The 2006 Region C Water Plan estimates that in order for NTMWD to meet the future water supply needs of the region to 2060, the equivalent capacity of raw water supplied by Lavon Lake (104,000 ac-ft/yr) will need to be developed or acquired every decade for the next five decades. The NTMWD has met the equivalent capacity of one and a half of Lavon Lake’s supply with the completion of the Upper Sabine Raw Water Supply Project and the East Fork Raw Water Supply Project.

The addition of the Bonham Water Treatment Plant and the Lake Tawakoni Water Treatment Plant will provide additional treatment capacity to the northern and eastern service areas. Construction at the existing Wylie Water Treatment Plants included the expansion of Water Treatment Plant IV, improvements and pump addition to Raw Water Pump Station No. 3, and cleaning of the residual lagoons.

Construction projects that increased the treated water deliveries to the NTMWD’s North System included the Allen/Plano/Frisco/ McKinney Pipeline Project; the Frisco-McKinney Pump Station Expansion and Ground Storage Reservoir; and the Farmersville Pump Station and Ground Storage Tank Project. Construction projects in the South System included the Rockwall Eastside 780 Pump Station, and the Terrell West Pump Station and Ground Storage Tank.

Other construction projects included the Wylie-to-Plano Water Line Relocation; the Rockwall to Royse City Water Line Relocation; the Wylie-to-Garland Water Line Capping; and the F.M. 544 14-inch Water Line Relocation. Also included in the 2007-08 construction program was a new Environmental Services Building and enhancements to the Homeland Security Program.
