Emergency Recovery After Extreme Flooding: The Clarksville WWTP

After an extreme flooding event, Hazen worked with Clarksville Gas & Water to repair and improve their WWTP. We had primary treatment restored less than a week after floodwaters receded, and the new and improved facilities will meet the community’s needs for the next 20 years.

Extreme flooding in the Cumberland River (TN) basin inundated the Clarksville Wastewater Treatment Plant, damaging nearly every piece of equipment and building at the plant site. Faced with the enormous tasks of condition assessment, FEMA paperwork, and rebuilding from the disaster, Clarksville Gas & Water hired Hazen and Sawyer to design and manage construction of the restoration of treatment operations for the City. The City is currently taking the opportunity to rebuild a state-of-the-art facility with more efficient treatment operations and increased wet weather capacity.
