Sister Grove Regional Water Resource Recovery Facility

Project Overview

The North Texas Municipal Water District (NTMWD) service area is seeing unprecedented growth. To effectively and proactively meet future regional needs, NTMWD has begun preparations for the Sister Grove Regional Water Resource Recovery Facility to be located approximately 1.1 miles east and 0.17 miles south of the FM 2933 and County Road 336 intersection.

From 2016 to 2017, NTMWD conducted a thorough evaluation to identify a suitable location for the proposed facility. As part of this process, several important factors were considered, including proximity to existing infrastructure, projected demands within the service area, physical geographic constraints, available land, existing and planned transportation corridors, capital and operations costs (such as the energy required for conveyance pumping) and regulatory requirements.

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 and citizens informed through permitting, design and construction 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 and 2019.

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.

 

Our team is currently designing and permitting the Sister Grove project, with construction scheduled to begin 2020. In order to serve the growing population in the area, the facility will need to be operational by 2023.

Also, the Texas Commission on Environmental Quality Permitting process is ongoing. To learn more about their process, visit the TCEQ website for municipal wastewater permitting.

 


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 permitting, design and construction 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, permitting, future construction and operations
  • Host open houses and informational meetings
  • Provide updates on the NTMWD website and social media channels
