Trigon Associates, LLC (Trigon) is a subconsultant for design & construction phase services for multiple sewage pumping station improvement projects in Shreveport, LA.
Lucas Sewage Pumping Station:
Trigon provided design support and construction phase services for improvements at the Lucas Sewage Pumping Station. The new station is a 3-pump station with firm capacity of 20,000 gpm (29 MGD), and the station discharges into a 48-inch force main that manifolds with other stations. The pumps are driven by variable frequency drives (VFDs). A permanent bypass structure was constructed at the site also, allowing flow to be diverted around the station, if necessary. Construction was complete in early 2015, and Trigon prepared a comprehensive O&M manual.
Agurs Sewage Pumping Station:
Trigon provided design support and construction phase services for improvements at the Agurs Sewage Pumping Station. The new station is a 3-pump station with firm capacity of 3,000 gpm (4.3 MGD), and the station discharges through an 8,000 LF 24” force main. The pumps are driven by variable frequency drives (VFDs). A permanent bypass structure was constructed, allowing flow to be diverted around the station, if necessary. Construction was completed in 2014, and Trigon prepared a comprehensive O&M manual for the station.
In addition to the Lucas and Agurs sewerage pump station improvements, Trigon performed construction phase services for the following sewer lift station improvement projects:
• Tou Don, Risinger & Sunset Lift Stations
