Aerial view of a large construction site at a wastewater treatment plant. There are several circular structures in various stages of construction, as well as large rectangular tanks and ponds. Heavy machinery, such as cranes and excavators, are visible on the site. The surrounding area is rural farmland.

This week, the new sewer main was installed along the back of the property. We will also set forms and rebar for the slab above the wet well and the main level at the headworks. The Oxidation Ditch will continue to see wall additions, with work beginning on laying rebar and forming the walls for the RAS (Return Activated Sludge) and WAS (Waste Activated Sludge) buildings. Additionally, the dewatering building will have rebar and wall forms installed.

Our office remains open during regular hours — Monday through Friday from 9:00 AM to 3:00 PM.

Gravity Main Installation Advances, Future Manhole Identified

Aerial view of a construction site showing progress on the installation of a gravity main. The green pipeline stretches across the site, with an excavator working alongside it. Several workers can be seen around the pipeline, and equipment is set up for the next phase of the project. In the background, structures for water treatment are under construction, and cranes are in operation. Nearby, a body of water is visible, bordered by dirt paths and construction material.

This line is one of two gravity mains that will supply our headworks for screening. Picture 2 shows the future location of a manhole installation.

Wet Well Slab Forms Installed, Piping Set, and Rebar Being Laid for Upcoming Pour

Aerial view of a large construction site with heavy machinery and equipment. There is a rectangular excavation with a concrete foundation and rebar visible. The surrounding area is mostly dirt and gravel, with some green fields in the distance.

Forms for the wet well slab are in place, piping is set, and rebar is now being laid for the slab pour.

Oxidation Ditch Taking Shape

Aerial view of a large construction site with multiple circular and rectangular structures. There are cranes, heavy machinery, and workers visible. The structures appear to be made of concrete and steel, with rebar and scaffolding in place. The surrounding area is mostly dirt and gravel.

The Oxidation Ditch is starting to take shape, with new sections being added each week. The second photo shows more exterior walls in place for the Oxidation Ditch. Additionally, the RAS and WAS building now has rebar in place, ready for the forms to be set.

Dewatering Building Advances with Form Installation Around Rebar Walls

Progress continues on the dewatering building, with forms being installed around the rebar walls. In the second photo, the crew is securing the forms and inspecting the rebar to ensure a perfect pour.

Changing Seasons

We took the opportunity to capture a beautiful photo of the changing season.

What's next?

The RAS and WAS building will begin setting forms and pouring walls. At the headworks, the main level slab will be poured, and plumbing will be installed throughout the building. The second clarifier is scheduled for water testing next week and will then be backfilled. More walls will be formed and poured for the Oxidation Ditch. Installation of the influent gravity line and the non-potable water line will continue throughout the week.
