FY 2019-2023 Capital Improvement Plan

Capital Improvement Plan City of Spencer, Iowa PROJECT SUMMARIES

FY 19 FY 23 thru

Sanitary Sewer

The proposed project consists of the rehabilitation of certain manhole location throughout the city each year. 12-SEW-001 MANHOLE REHABILITATION As the sanitary sewer system ages, the manholes will continue to deteriorate due to conditions they are subjected too. To ensure that they do not all fail at once, the Department plans on setting aside resources each year to rehabilitation two or three manholes each year. The proposed project will consist of cured in place sewer lining. By performing a lining project, the City is able to maintain and repair damaged sewer mains without having to dig up the roadway. The lining materials will repair most minor damage that can occur in a sewer main, however if the main is ruptured in any way, lining may not prove to be feasible. 13-SEW-001 SEWER LINING PROJECT The City conducted its first cure din place sewer lining project in FY 2013 and was pleased with the outcome. The City anticipates budgeting for a sewer lining project on a regular basis to extend the life of the concrete sewer mains. The sewers that are lined should delay total replacement of the line. Maintenance costs should also be reduced for a period as well. The proposed project will consist of three components. The first is updating the control panel at the W. 4th Street lift station. The control panel tells the pumps when to turn on and off and alerts staff if there are issues with the station. This portion of the project will be completed in 2015. The second component of the project is replacing the valves at the lift station. The valves control the flow of sewage into and out of the station. This portion of the project will be completed in 2015. The third component of the project is to repair the outside of the concrete wet well. This portion of the project will be completed in 2019. 15-SEW-001 W. 4TH STREET LIFT STATION REHABILITATI At the time of replacement, the current panel will be 42 years old. Over that time, technology has changed and the current panel is out of date. This will be an ongoing budget item each year.

Justification:

At the time of replacement, the valves will also be 42 years old and in need of replacement. By repairing the outside of the wet well, the life expectancy of the well will be extended. This project is being recommended by our Treatment Plant Operators Veolia. Maintenance costs should go down with a newer panel as well as the issue of parts availability.

Budget Impact:

The proposed project will consist of moving the control panel for the station above ground and replacing one of the two pumps with a dry pit submersible pump (10 HP) 18-SEW-001 NORTH LIFT STATION REHABILITATION At the time of replacement, the control unit would be 39 years old and in need of replacement. Technology has changed since these controls were installed. Also, the project would enable the lift station to operate during a flooding.

Description:

Justification:

Maintenance costs should be lower due to newer controls and a new pump.
