Septic Holding Tank

The US Army Corps of Engineers (USACE) seeks bids for a septic holding tank for the Visitors Center of the Mel Rieman Recreation Area, Ashtabula Lake, Valley City, ND. The current holding tank is the aeration tank of the decommissioned Sewage Treatment System (STS). The pit for the new tank will be the aeration tank of the STS. USACE site staff will prepare the new pit in advance. This will include removing the aeration tank covers, cover frame, and internal piping.

USACE will fill the bottom of the pit with appropriate bedding prior to delivery of the tank. USACE will consider bids for a two-tank system in the interest of fitting a 5,000-gallon system into the existing STS aeration tank pit. The Contractor must provide the tank and all necessary parts, labor, materials, transportation, and equipment necessary to transport, install, furnish, assemble, and seal a precast septic holding tank system.

Contractor will assemble and apply sealants per the manufacturer’s recommendations. The ground around the tank system pit can be saturated. Tank(s) must include an anti-buoyancy collar around the bottom of the tank per ASTM C1227. This supply contract does not include connection of the tank(s) to the existing sewer line. Any two-tank system will require the contractor to connect the tanks to each other.
