A 60 MGD treatment plant with ozone, membrane filtration and a new intake, producing drinking water that met every permit limit in its first week online.
The utility needed a new plant to replace an aging facility that could not meet tighter drinking water rules. The new plant had to tie into the existing intake and distribution system while the old plant kept serving customers. Ozone generation, membranes and chemical systems had long lead times, and the plant had to pass state startup testing before it could deliver a single gallon.
The approach.
- 01
Price and design together
Under progressive design-build, the utility saw open-book pricing at each design stage before committing to a guaranteed price.
- 02
Equipment bought early
Ozone generators and membrane racks were procured during design, so deliveries matched the installation sequence.
- 03
Tie-ins with no outage
Connections to the live intake and distribution mains were made in short, planned shutdowns with bypass pumping standing by.
- 04
Startup by the book
Every process started on clean water, then raw water, with operators trained at the controls before the state test.
The outcome.
“People turn on the tap and never think about us. That is how we know the plant is working.”
Startup manager, PerryWester
