Old clay sewer lines and brick manholes were replaced in the City of Commerce, Texas. These old lines and manholes were adding to the excessive infiltration and inflow experienced by the City. The project also replaced the drive unit for one of the Wastewater Treatment Plant clarifiers, installed a new polymer-enhanced sludge dewatering system, and a new 12″ sewer line for the latest Texas A & M University expansion.

Improvements included: 15,129 linear feet of 6″ to 12″ SDR 26 PVC sewer line; 43 new standard 4 feet diameter manholes, 7 manholes were removed, 11 manholes were abandoned, and 12 manholes were replaced; 113 customer service transfers; 85 linear feet of concrete paving and sidewalk repair; and 10,645 square yards of asphalt paving repair.

Hayter Engineering provided the following services: financial application, preliminary engineering report, environmental studies, easement-ROW surveys, geotechnical engineering, design plans and specifications, construction bid and award, construction review, materials testing, record drawings, and warranty review.

Hayter Engineering assisted the City of Commerce to obtain a $3,490,000 loan from the Texas Water Development Board. Funds from this loan were also used to replace water and sewer lines in the University area of the City and the repaving of Monroe Street. This project was completed in 2016.
