Excess Flow Lagoons

The capacity of the Galesburg Sanitary District Wastewater Treatment is 28 MGD.  Parallel to the bar screens there is a wet well for collection of excess flows during storms/rain/snow melt. The wet well has three 60 Hp submersible pumps. Each submersible is capable of pumping over 4,000 GPM. The excess flow is pumped into a three million gallon storage lagoon, then into a six million gallon storage lagoon. If more than nine million gallons are pumped, the excess flow is chlorinated (disinfected) and discharged to Cedar Creek. Once the storm ends and influent flow is reduced, the lagoons are drained back into the interceptor ahead of the bar screens.
