At 1,840 acres, the East Fork Raw Water Supply Project is the largest constructed wetland in the U.S. using reclaimed water to augment a surface water supply source

 

 

The NTMWD acts in accordance with its mission to meet the current and future water supply needs of its Member Cities and Customers. More than 1.6 million citizens rely on the treated water supply provided by the NTMWD. The NTMWD is a regional wholesale provider of potable water, with rates set at cost, no profits included, and no taxes collected.

Lavon Lake serves as the NTMWD’s main raw water supply source, with the NTMWD holding water rights in the reservoir. Lavon Lake also serves as a terminal reservoir for additional supplies that are transferred to the reservoir to augment supplies. The NTMWD holds water rights for raw water supplies from Lavon Lake, Lake Texoma, Jim Chapman Lake, Lake Bonham, and the Wetland. Additional supplies are available through a contract with the SRA, providing for water transfer to Lavon Lake from Lake Tawakoni and from a contract with the Greater Texoma Utility Authority for additional supplies from Lake Texoma.

Future water supplies will need to be developed to meet the water demands of a population estimated to exceed 3.8 million by 2060. Through the statewide water planning process, the NTMWD has identified numerous water management strategies that are included in the 2007 State Water Plan. Conservation, the wise and efficient use of current water supplies, and reuse strategies are estimated to comprise more than 25 percent of the future water supply. Even if the “highest practicable levels” of conservation and reuse are met, these strategies alone will not be sufficient to support the projected rapid growth expected within the NTMWD service area. Research completed by the
Texas Water Development Board has shown that on a state and local level, the more knowledgeable consumers are regarding their water source and supplies, the more likely they are to use this finite resource wisely and efficiently. To facilitate water-
efficient behaviors, the NTMWD continues to promote the state’s recognized public awareness and water conservation program, “Water IQ” (WIQ), providing water source information in addition to sensible water-saving tips.

During the 2008-09 Water Year (August 2008 - July 2009), the NTMWD treated and delivered 93.2 billion gallons of water for a 3 percent increase over the prior water year. Member Cities of the Water System used 85 percent of the total supply delivered, with the remaining 15 percent used by Customers.

During the 2008-09 Operations Year (October 2008- September 2009), Water System construction contracts totaled more than $388 million. In April 2009, the NTMWD placed into service the Wetland, a raw water supply included in the NTMWD 2007 State Water Plan. At 1,840 acres, the Wetland is the largest constructed wetland in the U.S. using reclaimed water to augment a surface water supply source. The Wetland will provide, at ultimate capacity, 102,000 acre-feet of water per year. More than 20 aquatic wetland species of plants were selected based upon their ability to enhance water quality and provide a natural wildlife habitat.

For the NTMWD water customers in the northeastern region of the service area, the NTMWD began serving the residents of the City of Bonham with a supply that is treated at the newly constructed, state-of-the-art Bonham Water Treatment Plant (WTP). Additional treatment capacity to the eastern service area will be provided from the Tawakoni WTP.

Construction projects that increased the treated water deliveries to the NTMWD North System included the Frisco-McKinney Pump Station Expansion, the Wylie- Plano Waterline Relocation, the Farmersville Pump Station and Ground Storage Tank, and the S.H. 380 Waterline Relocation. Construction projects in the NTMWD South System included the Wylie-Rockwall- Farmersville Pipeline, the Wylie-Garland Waterline Relocation, the Rockwall-Royse City Waterline Relocation, and the Forney-Terrell Pump Station. Other construction projects included expansions and modifications to various raw water pump stations. WA
