As a regional wholesale provider of potable water, North
Texas Municipal Water District (NTMWD) is committed to
meeting the current and future water supply needs of its
Member Cities and Customers. Water rates are set at cost,
no profits are included, and no taxes are collected. NTMWD
currently meets the water needs for over 1.6 million
consumers within its service area. Through the state water
planning process, it is estimated that the population is
expected to more than double by the year 2070 to an
estimated 3.7 million served. NTMWD has identified
additional raw water supplies to meet the future water
demands for the next 50 years. These identified water
management strategies are included in the 2012 State
Water Plan. NTMWD estimates that the equivalent of the
Lavon Lake water supply will need to be developed every
decade for the next 50 years to meet the future water
demands. The water supply may be from a diversity of
sources including conservation and reuse, connecting to
existing supplies or new reservoirs. The least expensive
water supply is the supply gained from conservation and
efficient use of the current available water supply which
comprises 22% of the future water supply planned for 2060.
NTMWD utilizes surface water supplies from Lavon Lake,
Lake Texoma, Jim Chapman Lake, Lake Tawakoni,
Bonham Lake and the East Fork Raw Water Supply Project,
commonly known as the wetland project. In May 2013,
NTMWD began purchasing raw water supplies, up to
60 million gallons per day, from Dallas Water Utilities.
In response to the ongoing drought and the loss of 28% of
NTMWD’s total water supplies from Lake Texoma due to the
presence of an invasive species, zebra mussel, NTMWD
continued to reinforce the water resources management
strategies within its Drought Contingency and Water
Emergency Response Plan to facilitate water use reductions.
Increasing the awareness of conservation as a water supply
is vital so that consumers become more knowledgeable
regarding their water source and supplies.
Since 2006, NTMWD has committed in excess of $13.6 million to implement WaterIQ: Know Your Water, the statewide public awareness and water conservation program, to facilitate and increase water efficient behaviors. During 2014, NTMWD conducted research and developed a youth water awareness campaign, Water4Otter. Water4Otter is intended to increase the conversation of water and water conservation in the home. The 2014 Water IQ campaign continued to elevate the ongoing drought and water supply issues facing the NTMWD. Through the continued success of the Water IQ program combined with the Member City and Customer conservation strategies, water consumption was reduced by an estimated 300-400 million gallons per day during the peak summer months of 2014.
During the 2013-2014 Water Year (August 2013 – July 2014), NTMWD treated and delivered 83.6 billion gallons of water, a decrease in delivery of 11% as compared to 93.3 billion gallons delivered during the 2012-2013 Water Year, with Member Cities utilizing 83% of the total supply delivered and the remaining 17% being utilized by the NTMWD Customers.
During the 2013-2014 Operations Year (October 2013 - September 2014), Water System construction contracts totaled over $605 million. Major projects included the Lake Texoma Outfall to Wylie Water Treatment Plant (WTP) Raw Water Pipeline; WTPs I, II, III, and IV Ozonation; Lake Tawakoni WTP; and the Wylie WTP finished water reservior and flow metering improvements. These major projects totaled in excess of $485 million. The construction of the Lake Texoma Outfall to Wylie WTP Raw Water Pipeline allows NTMWD to transport water from Lake Texoma by way of pipeline directly to the Wylie WTP for treatment. This pipeline restored the Texoma supply, 28% of NTMWD’s total raw water supply, while minimizing the spread of zebra mussels. The enhancement to the water treatment process at the Wylie WTP includes ozonation. With the ozonation project completed and fully operational in 2014, NTMWD now operates the largest ozone water treatment plant in the United States.
Construction projects at the Wylie WTP included: security enhancements and east gate improvements; residuals removal; finished water reservior & flow metering improvements; WTP I conversion to biologically active filtration (BAF) and improvements to existing drains; WTP II filter underdrain improvement and conversion to BAF; WTP II improvements to Basins 3 and 4; WTP III filter and underdrain improvements and conversion to BAF; WTP III variable frequency drives for washwater pumps; WTP IV conversion to BAF; WTPs I and II sludge line improvements; supervisory control and data acquisition system upgrades and operations; electrical improvements to WTP II Chemical Building; electrical improvements at Raw Water Pump Station No. 2, High Service Pump Station No. 1-1; High Service Pump Station 2-2 and 2-3 mechanical improvements; expansion of High Service Pump Station 3-1 to 350 MGD; improvements to WTP lagoons 1, 2 and 3; WTP I, 2.5 and 3.0 MG reservoir roof improvements.
Pump Station projects included: Farmersville Pump Station No. 2; modifications to the Lake Texoma Pump Station; expansion of the Frisco-McKinney Pump Station to 130 MGD; installation of a 50 MGD pump and improvements at the Apollo Pump Station; and piping modifications to the Haley Pump Station.
Additional construction projects included: south delivery point improvements, priority No. 1; waterline relocations for both the 24-inch and 20-inch pipelines along SH 78 from Kreymer Lane in Wylie to FM 6 in Lavon; FM 1378 20-inch and 60-inch waterline relocations; U.S. Highway 380 14-inch waterline relocation; Wylie-McKinney 20-inch waterline relocation at Stinson Road; 12-inch replacement line for the Princeton No. 1 and McKinney-Princeton- Farmersville pipelines crossing U.S. Highway 380; 42-inch and 24-inch waterline relocation along Stacy Road (FM 2786) from SH 5 (Greenville Drive) to FM 1378 (Country Club Road); Union Pacific railroad crossing protection of existing 72-inch Texoma pipeline; Wylie No. 3 delivery point metering station upgrade; North McKinney pipeline phases I and II; sludge lagoon improvements at Lake Tawakoni WTP and Bonham WTP; Lake Tawakoni WTP chlorine dioxide system; 121 site facility water transmission pipeline relocation at SH 121; Chapman Lake water access Task B (dredging); and Tasks 1, 2, and 3 – Administration Building structural repairs, building renovations, and building addition.

The North Texas Municipal Water District (NTMWD) developed a new mobile gaming app featuring wildlife native to Lavon Lake empowering children to help their parents save water and increase the conversation of water conservation within the home. This fun interactive education tool — one of the first of its kind created by a water utility has been developed as part of an overall education campaign “Water4Otter” that teaches children the importance of water conservation and encourages them to talk about saving water at home. As part of the game, Otis the Otter and Farrah the Fox provide water-saving tips to help protect their natural habitat — Lavon Lake — and to use water efficiently.
The Watr4Otter App is available for free download at Google Play and App Store
