August Monthly Meeting
Our August monthly meeting will be held at the Brown and Caldwell office in Walnut Creek! The address is 201 N Civic Dr Suite 300, Walnut Creek, CA 94596, and we will begin at 11:00 a.m. on Tuesday, July 8th, 2025. Take the South Lobby elevator to the 3rd floor.
The presentation is titled West County Wastewater’s Progressive Design Build Treatment Plant Project, and will be provided by Guyton Durnin (HDR). Guyton will be presenting on West County Wastewater’s (WCW) 60-year-old 12.5 MGD wastewater treatment plant being upgraded using a progressive design-build (PDB) contract. This project aims to reduce energy consumption and GHG emissions, improve operational safety and efficiency, and improve the quality of the biosolids produced. Consistent with the vision and strategic goals, this project will result in the development of sustainability upgrades that support WCW’s strategic initiatives to adopt infrastructure maintenance and modernization strategies that maximize performance, reduce risk, and ensure reliable service in collaboration with local, regional, and national partners to further the mission of WCW. This will allow WCW to be an environmental steward in our community through a commitment to reducing carbon emissions, maximizing resource recovery, minimizing our ecological footprint and making significant strides toward becoming a carbon-neutral enterprise. The presentation will include some lessons learned in regards to working at a 70 year old facility with as builts that don’t always tell the truth on what is abandoned pipe and what is something that can lead to 20,000 gallons of sludge in your excavation.
