Trigon Associates, LLC (Trigon) was selected by the City of Slidell as the prime engineer for this project, which generally consisted of the rehabilitation of six (6) sewer pump stations.
Five (5) stations were converted from suction-lift stations to submersible stations, while one (1) is an existing submersible station that was rehabilitated.
The wet wells of each station were renovated and coated in accordance with the City’s standards and preferences. Replacement of the mechanical systems, electrical and control systems, and various site improvements were included. Electrical and control systems for the new stations were set above flood stage to mitigate the potential for damage and discharges due to future flood events.
Trigon provided the following general services:
• Design of improvements, including site visits to verify field conditions and preparation of contract documents (specifications and drawings).
• Bid phase services to support the City in successfully bidding and awarding the construction contract
• Construction phase services, particularly with respect to conducting the pre-construction conference, technical review of submittals, responding to RFIs, and support to the City in contract closeout procedures (including final change order).
The project is funded via a federal grant from the US Environmental Protection Agency through the University of New Orleans and Lake Pontchartrain Basin Foundation.
Construction was completed in the summer of 2015.
