We are currently on day 275 of the 660 days allowed for the construction of the new wastewater treatment plant. The project is on schedule and in budget. Contractors have completed the masonry walls and are installing the roof on the Administration Building. The beams for the bridge crane have been installed in the maintenance shop. Most of the new underground electrical line to serve the plant is installed. The interior walls of the sludge holding tanks and digester are currently being poured. The digester is where the excess sludge generated during the biological process will be treated and stored in the holding tanks until transported by tanker and land applied. The Contractor has completed the masonry walls and installed the roof trusses on the Sludge Transfer Pump Station. The underslab piping and electrical conduit is currently being installed in the Sludge Processing & Blower Building. The concrete walls for the Influent Pump Station and Screening/Grit Removal structures are still under construction. The Contractor continues to work on the interior walls and catwalks in the aeration basin. The catwalk to the center cage, feedwell assembly, center cage, drive assembly, & sludge scraper has been installed in Clarifier #2.

We are currently on day 260 of the 660 days allowed for the construction of the new wastewater treatment plant. The project is on schedule and in budget. Contractors are working on the masonry walls of the Administration Building. The plumbing, electrical conduit and roof trusses have been installed. Construction has begun on a new electrical line to serve the plant. The floor and exterior walls of the sludge holding tanks and digester have been poured. Work is continuing on the interior walls. The digester is where the excess sludge generated during the biological process will be treated and stored in the holding tanks until transported by tanker and land applied. The sludge holding tanks and digester is one structure separated internally by walls. The Sludge Transfer Pump Station walls have been poured and the electrical and plumbing have been installed. The concrete foundation for the influent pump station and screening/grit removal structures has been poured and the walls are under way. Pouring the concrete in the walls of the aeration basin continues in this hugh structure. The aeration basin will be the heart of the biological process.

        Contractors have completed the construction of Clarifier # 2. Clarifier # 1 had been completed prior to our last blog. The floor of the aeration basin has been poured and construction is continuing on the walls. The floor of the sludge holding tanks and digester have been poured, and construction has begun on the walls. The sludge holding tanks and digester is one structure separated internally by walls. The digester is where the excess sludge generated during the biological process will be treated and stored in the holding tanks until transported by tanker and land applied. A diffuser line has been installed on the bottom of the river to evenly disperse the treated effluent into the Wateree River. The new diffuser design is a drastic improvement over the current effluent pipe that discharges onto the bank of the river. The pipe currently being used is noticeable from the river, whereas the new diffuser line will not be seen from the river. Construction of the Administration Building is also underway with the foundation being prepared, now that the plumbing and electrical conduit has been installed. Please see the photograph gallery.

        Contractors completed the construction of the floor and wall for Clarifier #1, and Clarifier #2 is under construction. A clarifier is a tank or basin in which water, or wastewater in this case, is held for a period of time during which the heavier solids settle to the bottom and the lighter materials float to the surface. The floor and walls of the scum pump station, which pumps the settled material from the clarifiers back to the head of the Plant,  have been constructed. Construction has also began on the aeration basin, our largest structure. An aeration basin is a tank where raw or settled wastewater is mixed with return sludge and aerated. The underdrain piping to the aeration basin has been installed, and also partial sections of the basin's floor are complete. Three manholes and a section of 42" influent pipe, the pipe delivering the City's wastewater to the plant, have been installed.

        Construction at the wastewater treatment plant (WWTP) is continuing. Contractors have recently completed the installation of an 18-inch storm drain line to the river to provide drainage at the site. In addition, the ground of the administration/control building and clarifier sites is ready for construction. The next step will be to lay the foundation. Grading work is ongoing in the administration/control building parking areas and aeration basin sites. The grading in these areas has met the minimum specified 98% compaction requirement to provide a stable base for structure and road construction. Also, the stormwater basin has been graded and seeded to provide erosion control.
