ARCHBOLD WASTEWATER TREATMENT PLANT
It’s been a busy couple years at the Archbold Wastewater Plant. A new lift station was constructed, along with the movement of the sanitary line along Brush Creek. Why is this important? This lift station handles all the waste water south of the bridge, in addition to Ridgeville sewage. This also provides department employees a much safer work environment, and allows for ample room for valves and electrical boxes. Pumps can be accessed easier and allows this work to be completed much more efficiently.
The sanitary line from Woodland Oaks was moved as well. This has helped prevent extra water from getting into the sewer when Brush Creek is flooded. Previously, the lift station was overwhelmed when the creek flooded and the extra sewage was then sent to the plant to be treated, which was not necessary. With several substantial rainfalls in recent months, the amount of sewage pumped has been significantly lessened. We’re very fortunate to have this project completed.
Many changes happened at the Wastewater Treatment Plant as well. The village no longer uses chlorine for disinfection. This in turn eliminates the need for sodium bisulfite. A UV disinfection system is now used. This is much safer for our employees as well as for community members. An example of this: if there had ever been a chlorine leak, it would have been necessary to evacuate a five mile radius surrounding the plant. With the new system UV disinfection happens with special bulbs (two banks of 12 bulbs), which modifies the cells of e-coli bacteria so they cannot reproduce.
Three large storm pumps and valves were also added at the treatment plant. Valves and pumps here are activated by the level at Brush Creek. Prior to construction of these tanks, high water level in Brush Creek prevented the discharge of water because the gate would shut. This required department employees to set up portable pumps to get clean water into the creek to prevent a back-up at the plant. The new pumps and gates now have level sensors that shut the appropriate gates so no back up can occur. This forces the water out into the creek.
A wet weather station was added also. This was necessary to prevent high flow. This station is designed to keep the screen building from flooding. Additionally, two digester lids were replaced, from 1960 and 1973 respectively. This was a very dangerous portion of the project as the concrete was in terrible shape. The purpose of the digester is to capture methane gas which is made through a biological process. The new digester lids have helped tremendously.
Safety, efficiency, and functionality are just a few of the benefits of the many upgrades and renovations made at the Archbold Wastewater Treatment Plant.
