Northwest Regional Excess Flow Facility project description and overview presented at public open house
On Wednesday, May 11th, an open house was held at the renovated Northwest Regional Excess Flow Facility in Round Lake Beach. This was the former site of the Round Lake Area Sanitary Plant which was still pre-treating sewage for several years even after a new plant was built in Fox Lake. The renovated facility is now designed to reduce sanitary sewer overflows in all areas served by the partnership members. Those members consist of the villages of Round Lake, Round Lake Beach, Round Lake Heights, Round Lake Park, Hainesville, Lake Villa, Fox Lake, and the Lakes Region Sanitary District.
This facility is designed to reduce basement backups during times of significant rainfall. It consists of a new pump station with three large pumps, major equipment investment, and a lagoon system capable of storing 20 million gallons of primary treated wastewater. The overall project cost was $7.5 million. Native plants have been utilized throughout the site and over 250 trees were planted. A portion of this site can be renovated and used as a recycling facility.
Speakers at the Open House were Lake County Board Chairman Aaron Lawlor, Round Lake Beach Mayor Rich Hill, District 5 Lake County Board Member Bonnie Thomson Carter, and Lake County Public Works Director Peter Kolb. After the welcoming remarks by Lawlor, Hill and Carter, lunch was served while Director Peter Kolb presented a project description and overview after which everyone was invited to tour the facility.
The tour consisted of viewing the pump station control room along with a view down into the pits containing the huge valves leading to the pumps themselves.
Under normal circumstances, untreated sewage from the Round Lake Area goes directly to the Lakes Region sanitary plant. Under heavy rainfall conditions, when the plant is experiencing heavy input, one or two large vortex pumps are activated which sends the sewage to the swirl tank that separates the heavy sludge and sends only the primary treated wastewater out into the large lagoons. There is one lagoon that does not have the stone embankment and would only fill with wastewater under extreme conditions.
The huge vertical vortex pumps are raised and lowered on a rail system which allows for easy maintenance if required. They pump the water to the swirl tank which is located in the large circular concrete structure that everyone climbed up on to view the site.

Those of you living in these “partnership” areas are funding this improvement with a $1.50 per month “Excess Flow – Surcharge” on your water & sewer bill that began back in January 2014 and you will continue paying that surcharge (an IEPA loan) for a total of 20 years.
