As part of the project, Ameresco rehabilitated more than 190 manholes throughout the city's wastewater infrastructure that have shown signs of deterioration. The project is intended to help minimize the risk of inflow and infiltration of stormwater and address potential structural failures, ultimately reducing system inefficiencies and wastewater treatment costs associated with aging manholes.

</p><p xmlns="http://www.w3.org/1999/xhtml">
"We're proud of our continued partnership with the City of Mesquite and the successful completion of this important infrastructure investment," said Louis Maltezos, Co-President of Ameresco. "Modernizing wastewater infrastructure strengthens system reliability and positions communities to meet future needs with confidence. This project supports the modernization of critical infrastructure to strengthen system reliability and long‑term performance."

</p><p xmlns="http://www.w3.org/1999/xhtml">
Ameresco provided a full wastewater rehabilitation solution that included the supply and installation of a multi-layered polymeric lining system to restore structural integrity of the manholes and extend service life. Prior to coating installation, each manhole structure underwent a comprehensive cleaning process, with any identified holes or cracks grouted and plugged to create ideal surface conditions for maximum coating adhesion and long-term performance.

</p><p xmlns="http://www.w3.org/1999/xhtml">
"The City of Mesquite is committed to providing quality water and wastewater services to our customers with limited disruptions," said Cliff Keheley, City Manager. "This proactive approach to rehabilitate aging assets not only prevents disruptions, it manages costs. Programs like the ones offered by Ameresco help the City provide consistent and affordable services to our citizens."

</p><p xmlns="http://www.w3.org/1999/xhtml">
This project marks the latest initiative in a successful multi-year partnership with the City of Mesquite focused on modernizing critical water infrastructure. Previous collaboration efforts included the implementation of a comprehensive smart metering infrastructure project serving the city's residential and commercial water utility customers.
