BACKGROUND
In August 2023, the City of Mesquite (“The City”) contacted NTMWD engineering and planning departments regarding the need to send additional flows into the Mustang Creek Interceptor system to accommodate a 600-acre planned single-family development called Talia. The City and NTMWD staff have coordinated the design of improvements to the Mustang Creek Interceptor with the City’s design engineer, Nehemiah Company, LLC, which includes:
• Replacement of approximately 500 linear feet of 18-inch pipeline with a 24-inch pipeline.
• Replacement of a wastewater manhole with a larger wastewater manhole.
• Repair of the internal liner for an existing manhole.
The City, Nehemiah Company, LLC, and NTMWD Engineering, Planning and Wastewater Operations staff completed a series of design review meetings between November 2023 and January 2024. NTMWD staff approved the final design plans on January 29, 2024.
