GK Engineers provided full MEP design for Waste Management’s new 18,000 SF CNG truck maintenance and wash facility in Lake Charles, Louisiana. The building has six full-service maintenance bays, a 4,000 SF office and a drive-through wash bay for refuse trucks, and it is fully air-conditioned, sprinklered and on standby power.

A 30-ton dedicated outdoor air system conditions the shop. The truck bays exhaust 32,000 CFM under a natural gas detection system for CNG safety, and an 800A, 480V service with a 500 kW natural gas generator sized for the full building keeps the fleet running through an outage.

Wash water and shop fluids run through a trench drain and oil separator ahead of the municipal sewer, with overhead fluid reels at every bay. The facility was completed in early 2023.
