Wastewater Generation and Management in Underground Utility Vaults and Manholes

38,708 views

Published on

Underground utility networks face a number of maintenance challenges, including chronic water intrusion, debris and sediment build-up, and the presence of oil and sheen. Dewatering methods for vaults and manholes are forced to evolve with the Increasing environmental regulations in storm water management, but there are risks and tradeoffs involved. Passive and active protection systems are accessible and can be easily implemented as solutions to certain underground challenges, as illustrated by Dan Parker during this presentation at the USWAG 2015 Decommissioning and Low-Volume Waste Committee Workshop in Detroit, MI.
