EMMONAK WATER & SEWER UPGRADES

Location: Emmonak, AK

Working directly for the City of Emmonak, CRW provided planning, surveying, design, and CA services for the community’s existing piped water and sewer system. The primary upgrades included installation of helical piles to better protect the system from seasonal flooding; replacement of deteriorating, stick-framed service boxes; regrading of the vacuum sewer mains; reconfiguration of the high/low-pressure water system to four circulating loops; and repair of the glycol heat trace system for the sewer mains, raw water line, vacuum sewer mains, and the force main to the sewage lagoon. Other improvements included the installation of water circulation pumps in over 200 houses, and upgrades to the heating systems, vacuum sewer station, and force main pumps in the WTP.
