Located where a ditch on Cook County Forest Preserve property enters the Skokie River, the original pump station was built in 1995 to provide drainage for more than 900 acres, said Megan Pierce, assistant to the village manager in Winnetka.
When the Skokie River rises higher than the ditch during heavy storms, the pump station allows the village to pump out flood waters, Pierce said.
As designed by consulting engineer Christopher B. Burke Engineering Ltd., and built by Boller Construction Company, Pierce said the station improvements increase the capacity of the pump station, improving the flow in upstream storm sewers.
For example, Pierce said the new pumps increase the station's pumping capacity from roughly 40,000 gallons per minute to 60,000 gallons per minute.
The recently completed pump station project is just one of the components of the village's stormwater management program, the largest of which is the proposed $34 million Willow Road Tunnel project, which would discharge stormwater into Lake Michigan.
