GALLIPOLIS — Gallipolis Wastewater Treatment Superintendent Brian Lane recently summed up recent measures with the completion of the Gallipolis Wastewater Plant since the facility’s upgraded construction began in 2013.
Lane spoke at this week’s meeting of Gallipolis City Commission.
“The original plant was created in 1958 before that it was just cross connection sewer straight to the river,” said Lane. “It was primary settling tanks, chlorine and then sent to the river with very minimal treatment. They underwent a big upgrade in 1988 where they added the screening generator, two additional primary tanks, stepped up the sludge digestion process and added some grit removal, trickling filters, settling tanks for the finals and then upgraded to the chlorination along with dechlorination. At one point, one million gallon equalization processes for high flow (were added).”
Between the 1988 upgrade to the most recent upgrades, the biggest may be that the plant previously could handle a design flow of 1.3 million gallons potentially flowing a day through the facility to now being able to handle an average of 2 million gallons. The average of wastewater flowing through the facility currently is around 1 million gallons. If pushed to capacity in a more dire situation, the facility could handle around a little over 7 million gallons a day. Lane said that was just processing the wastewater and not really treating it when it came to the 7 million number. That would however help relieve sewers systems to avoid backups in basements and the like.
The city is currently waiting on word from the county before taking up more additional sewage treatment based on agreements established between county government and the city as the county goes about completing new sewer line construction in Green Township. City Manager Gene Greene said he anticipated to hear such word within two to three weeks.
Lane said with the introduction of new tank processes, odor complaints have decreased as a more “earthy” smell since the change over to aeration processes.
