About Our Water System

 

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.

 

The population served by the NTMWD currently stands at
over 1.6 million people and is expected to more than double
by 2070 to 3.7 million residing inside the NTMWD service
area, according to the initially prepared state water plan.
NTMWD has identified additional raw water supplies to
meet the future water demands over the planning period.
These identified water management strategies are included
in the 2016 Initially Prepared Region C Water Plan
(http://www.regioncwater.org) For NTMWD, the top two
additional water supply sources that will help meet the
projected water needs through 2040 are the Trinity Main
Stem Pump Station and the Lower Bois d’Arc Creek
Reservoir project. Other identified water supply strategies
vary from a diversity of sources including: conservation and
reuse, connecting to existing water supplies, and/or
new reservoirs.

 

NTMWD obtains its raw water supplies from Lavon Lake,
Lake Texoma, Jim Chapman Lake, Lake Tawakoni, the
Upper Sabine Basin, Lake Bonham and reuse of treated
wastewater effluent from its Wilson Creek Regional
Wastewater Treatment Plant, and the East Fork Raw Water
Supply Project
.

 

During the 2011 to 2015 North Texas drought, NTMWD was
unable to use 28% of available water supply due to the
presence of an invasive species, the zebra mussel, in Lake
Texoma.  NTMWD was able to continuously supply water
throughout the extended drought despite the loss of this
major water source by implementing a multi-faceted
response plan. 

 

First, regional water consumption was reduced through strong cooperation with NTMWD Member Cities and Customers who successfully implemented the water resource management strategies included in their Drought Contingency and Water Emergency Response Plans.  Second, NTMWD and its Member Cities sought legislative relief from the Lacy Act which culminated in the passage of the North Texas Zebra Mussel Barrier Act of 2012. Third, the NTMWD implemented in earnest the construction of the Lake Texoma Outfall to Wylie Water Treatment Plant (WTP) Raw Water Pipeline in order to deliver Lake Texoma water directly to the Wylie Water Treatment Plant allowing any present zebra mussels to be eradicated during the treatment process.  Finally, in May 2013, NTMWD began temporarily purchasing additional raw water, up to 60 million gallons per day, from Dallas Water Utilities for a 3-year term. Reservoir levels began to slowly recover in 2014, and the Texoma pipeline project was placed into service during the summer of 2014, restoring NTMWD supply at a critical time during drought. The reservoirs finally filled to full conservation pool levels in 2015, a year when several rainfall records for Texas were exceeded.  In May 2015, NTMWD was able to end drought plan restrictions and transition into the NTMWD Water Conservation Plan (February 2014), allowing consumers to irrigate their lawns up to twice per week if needed.

 

Increasing the awareness of water conservation and water use efficiency as a water supply is vital for supplying water needs both today and in the future. Research results indicate the more knowledgeable consumers are regarding their source water, supplies, and water use habits, the more inclined they are to make wise water use behavior changes.

 

Since 2006, NTMWD has committed in excess of $17.4 million to implement WaterIQ: Know Your Water, the statewide public awareness and water conservation program, and Water4Otter to facilitate and increase water efficient behaviors. In the fall of 2014, NTMWD launched Water4Otter, a youth water awareness campaign. Water4Otter’s campaign objective is to increase the conversation of water and water conservation in the home. Students at 50 schools received a Water4Otter presentation and students were provided clings with water saving tips to take home and engage a conversation of water with their parents. At the completion of the fall 2014 Water4Otter presentations, research was conducted to determine the success of the newly launched campaign. Research indicated that 78% of students that viewed a Water4Otter presentation had at least one water-related conversation with their parents. Research also indicated that 78% of the students participated in the use of the clings at their homes. The 2015 Water IQ campaign continued to elevate the need to reduce water use due to the ongoing drought and water supply issues that NTMWD faced. The key messaging highlighted the use of WaterMyYard.org. Through the continued  success  of  the  Water  IQ  program combined with the Member City and Customer’s conservation strategies and drought response strategies, water consumption was reduced by an estimated 300-400 million gallons per day during the peak summer months of 2014.

 

During the 2014-2105 Water Year (August 2014 – July 2015) NTMWD treated and delivered 80 billion gallons of water, a decrease in delivery of 4% as compared to 83.6 billion gallons delivered during the 2013-2014 Water Year, with Member Cities utilizing 83% of the total supply delivered and the remaining 17% being utilized by the NTMWD Customers.

 

As of September 30, 2015, construction contracts for the Water System totaled over $616 million. Major projects included: the Lake Texoma Outfall to Wylie Water Treatment Plant (WTP) Raw Water Pipeline; Wylie WTPs I, II, III, and IV Ozonation; Trinity Main Stem Pump Station and Raw Water Pipeline; Wylie WTP II Clearwell and Disinfection Improvements; the NTMWD Administrative Building Structural Repairs, Building Renovations, and Building Addition, Tasks 2 and 3; the Wylie WTP Finished Water Reservoir and Flow Metering Improvements; the North McKinney Pipeline, Phases I and II; and the Lake Tawakoni WTP.

 

Enhancement to the water treatment process at the Wylie WTP include ozonation. With the ozonation project completed and fully operational in 2014, NTMWD now operates the largest ozonated water treatment plant in the United States.

 

Construction projects at the Wylie WTPs included: Wylie WTP east gate improvements and complex chemical system improvements phases 1A and 1B; Wylie WTP I conversion to biologically active filtration (BAF), improvements to existing drain, and 2.5 MGD and 3.0 MGD reservoir roof improvements; Wylie WTP II improvements to Basins 3 and 4;  Wylie WTP III filter and underdrain improvements, conversion to BAF, and lagoon improvements; Wylie WTP III variable frequency drives for washwater pumps; High Service Pump Station No. 1-1 electrical improvements; and High Service Pump Stations 2-2 and 2-3 electrical and mechanical improvements. Many of the projects are multi-year projects.

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 provides water-saving tips to help protect their natural habitat — Lavon Lake — and to use water efficiently.

 

The Water4Otter App is available for free download at Google Play and App Store
