The North Texas Municipal Water District (NTMWD) service area is seeing unprecedented growth. To effectively and proactively meet future regional needs, NTMWD is building the Sister Grove Regional Water Resource Recovery Facility (RWRRF) to be located approximately 1.1 miles east and 0.17 miles south of the FM 2933 and County Road 336 intersection.
In April of 2020, NTMWD received the wastewater permit from the Texas Commission on Environmental Quality (TCEQ). Construction on the Sister Grove RWRRF is scheduled to begin in late summer 2020.
As NTMWD works to plan and build the infrastructure needed to serve our fast-growing region, we’re looking for all possible ways to manage costs for the people we serve. On February 27, 2020, the Texas Water Development Board (TWDB) approved $459 million in low-interest state funding for the Sister Grove RWRRF. The TWDB Clean Water State Revolving Fund (CWSRF) Program financing is anticipated to save more than $200 million in interest costs on this project.
As the process moves forward, NTMWD will communicate and coordinate with the neighboring cities of McKinney, Princeton and New Hope. We are committed to keeping these cities informed through the construction and operation phases.
Previous communication activities included public meetings in June 2018 in McKinney and in November 2018 in New Hope. District officials spoke about the project at both McKinney and New Hope city council meetings in June 2018, and District staff had an informational booth on the project at New Hope’s National Night Out events in 2018 and 2019. Additionally, in posted meetings that are open to the public, the NTMWD Board of Directors discussed and voted on various portions of the project in 2017, 2018, 2019 and 2020.
After listening to residents and meeting with city officials in McKinney, New Hope and Princeton, NTMWD has made some changes to the project. The peak flow basins have been moved closer to the plant and further away from the property boundaries. Additionally, we are adjusting the screening planned for the south end of the property to better shield the view of the facility for homeowners in the area.
Now that NTMWD has received the required wastewater permit from the TCEQ, our team will prepare for construction. Crews will survey the site and begin site preparation prior to the expected start of construction in late summer 2020. In order to serve the growing population in the area, the facility will need to be operational in 2023.
Frequently Asked Questions
What is a Water Resource Recovery Facility?
Water Resource Recovery Facilities provide wastewater treatment prior to discharging into a body of water. These facilities are a critical element in maintaining the health of our watersheds. NTMWD is voluntarily implementing a watershed protection plan to further safeguard the Lavon Lake watershed with increasing urbanization in the area.
Why do we need the new Sister Grove Regional Water Resource Recovery Facility?
Currently, 700,000+ people are served by two facilities and projected growth will exceed the existing facilities serving Collin County by 2023.
How will the environment be protected and impacts mitigated?
Protecting water resources and preserving the natural environment is a high priority. Similar NTMWD facilities operate in this same manner and discharged water is typically of higher quality than naturally existing water in creeks and streams. As our team determined the location of the facility and its outfall location, a site was selected to minimize impacts on area streams and Lavon Lake. Sister Grove RWRRF will be designed to maintain the natural surroundings at the outfall location. As the project continues, NTMWD will:
- Comply with all local, state and federal environmental protection requirements from design through operations
- Engage with area communities throughout facility planning, construction and operation
- Treat recovered water resources to high quality in compliance with TCEQ requirements
- Will include advanced treatment and odor control technologies
How can I stay connected with the project?
NTMWD is committed to keeping the cities and residents of McKinney, Princeton and New Hope informed through the construction and operation phases.
This includes directly affected or adjacent community members to ensure the successful integration of the facility within the community. Our team will:
- Work with community members to plan for and reduce impacts due to construction
- Communicate regularly on planning, construction and operation
- Provide updates to the cities of McKinney, New Hope and Princeton
- Provide updates on the NTMWD website and social media channels
