Water Treatment Plant Construction Update

Information about onsite work is outlined below. Please note, schedules are subject to change.

Ozone system - northeast of site

Work is progressing well on the new ozone system. Crews and electricians have been focused on installing new equipment and piping inside the structures (pictured above). The contractor and water treatment plant staff are gearing up to begin testing and commissioning the new state-of-the-art ozone system, which will be online in the coming months.

A weather barrier coating has been applied to the exterior of the ozone generator building, and architectural siding and pearl panels are being placed. The brick veneer is complete (pictured right). Roofing and skylights have also been installed.

The ozone basin has passed the water test. Miscellaneous duct bank and piping work continues around the new ozone structures and administration building. During these activities, neighbors close to the site should expect some noise and vibration during work hours.

Site improvements and hardscaping

Hardscaping and site improvements are ongoing across the site. In December, the Mapleton site fence was shifted to the edge of the curb, to enable crews to continue working on the bio swales and sidewalk. All concrete has now been poured for the remainder of the Mapleton sidewalk. The chain link fence will be removed once construction is complete at the site.

Site improvements, stone walls, sidewalks and hardscaping work includes digging and preparing the site, placement of materials, forming, compacting, pouring concrete and saw-cutting stone. During this work, neighbors close to the site should expect an increase in intermittent noise and vibration from equipment.
