This rain resulted in four sanitary sewer overflows in four locations in the City. The first location was at 17600 Lucy Circle where approximately 66,250 gallons were discharged to a ditch which leads to the Poplar Creek about 1 mile away. The second location was at Amber Court and Bermuda Boulevard where approximately 137,600 gallons were discharged to a ditch which leads to the Fox River about 1 mile away. The third location was at Elderlawn Parkway and N. 158th Street where approximately 205,200 gallons were discharged to a ditch which leads to the Butler Ditch about ½ mile away. The fourth location was at Three Meadows Drive and Elderlawn Parkway where approximately 59,500 gallons were discharged to a ditch which leads to the Butler Ditch about ½ mile away.
It should be noted that over 600 properties in Brookfield near these areas were without power during a portion of the storm, which can lead to overflowing sump crocks which drain to basement floor drains and into the sanitary sewer. Property owners can protect themselves and their neighbors by having battery backups for their sump pumps and/or generators for power outages. The City is also working with WE Energies to improve reliability of the electrical power grid in Brookfield.
The City has scheduled capacity improvements to the sanitary sewer system in the Elderlawn Parkway area as well as conducting a program to reduce sources of infiltration and inflow into the sanitary sewer system.
