Water & Wastewater Treatment

Country Lakes 70,000 GPD Sewer Treatment Plant

Country Lakes was the first plant Gainey's manufactured and installed to meet the new LUS specifications for sound attenuation (must be quieter than 50 dB) and ease of maintenance.  This custom wrap-around sewer treatment plant was also extremely efficient - reducing air and energy requirements by 25% due to the shortened aeration, RAS and WAS return lines.

Custom Structures

Breasting Dolphin

The Mississippi River Port Breasting Dolphins was the project that kept Gainey’s on its toes! From casting in 8’2” steel plates with Nelson studs welded in a specific pattern, to flush-cast pipes, this project required great attention to detail. With frequently changing details, it also required updates to both designs and fabrication methods throughout the project. Never a company to shrink from a challenge, Gainey’s completed the project accurately and on time. The final touch on this project was receiving a 2016 NPCA CUP Award in the Underground Category.

Arbor Walk 200,000 Gallon Holding System

Talk about CUSTOM!  Every facet of this job was custom designed from the 12' tall precast panels to the 3 types of stainless steel mechanical connections to the 20 sealant trials for the joint design!  All of this came together to provide 200,000 gallons of holding capacity for Arbor Walk Subdivision's sewer treatment plant that was installed in only 1 week!

Livingston Parish Auger Trash Trap

This very narrow structure had to be cast with precise interior dimensions to match the screw auger that would be screening and removing the miscellaneous trash and debris commonly found in prison wastewater.
