RE: Twin Ridge Lift Station Abandonment Project
INTRODUCTION
The enclosed resolution provides for the acceptance of the construction contract for the
Twin Ridge Lift Station Abandonment Project.
BACKGROUND
In 2015, the city purchased the sanitary sewer collection and water distribution systems,
serving Twin Ridge subdivision, from Twin Ridge Water Corporation. The sanitary
sewer collection system is comprised of the gravity collection system, a lift station and a
lagoon treatment facility. Also, in 2015, the City constructed a new lift station on Lake
Eleanor road. The Lake Eleanor road lift station was designed to serve the area
between Key West Drive and U.S. highway 151/61, north of Lake Eleanor road, along
with the ability to serve an additional 24 properties within Twin Ridge subdivision.
DISCUSSION
The Twin Ridge Lift Station Abandonment project was completed by Gansen
Excavating, Inc. in the final contract amount of$106,851.05.
The project provided for the abandonment of the existing lift station and connect it to a
portion (24 properties) of the Twin Ridge subdivision to the City's sanitary sewer
collection system. Connecting these properties has reduced the flow entering the
existing lagoon treatment facility located within the subdivision.
A future project, will include abandoning the lagoon treatment facility and connecting the
remaining portion of the Twin Ridge subdivision to the City of Dubuque sanitary sewer
collection system. This project is planned for FY2021.
