SUBJECT:SANITARY SEWER SYSTEM IMPROVEMENTS PROGRAM (BASIN 11)
COUNCIL ACTION FORM
BACKGROUND:
This is the annual program for rehabilitation/reconstruction of deficient sanitary sewers and
deteriorated manholes at various locations throughout the city. The goal of this program is to
identify and remove major sources of inflow/infiltration (I/I) as a means of lowering the peak
wet weather flow at the treatment plant. By eliminating I/I in these sewer mains, the sanitary
sewer system will also regain needed capacity.
This project includes the rehabilitation of sanitary sewer segments and manholes within Basin
11, which is located on the east side of Ames. WHKS & Co. of Ames, Iowa, has completed
the plans and specifications for the work. The revenues and expenses associated with this
program are estimated as follows:
Description Available Revenue Estimated Expenses
State Revolving Fund (SRF)$2,500,000
Construction (est.) $2,100,000
Engineering/Administration (est.) $ 150,000
TOTAL $2,500,000 $2,250,000
The debt service payments in conjunction with this State loan will be paid from the
operating expenses from the Sanitary Sewer System Improvements program.
ALTERNATIVES:
1. Approve the plans and specifications for the Sanitary Sewer System Improvements
Program (Basin 11) project, setting February 18, 2026, as the bid due date and February
24, 2026, as the date of Public Hearing.
2. Direct staff to pursue changes to the project.
3. Do not proceed with this project at this time.
CITY MANAGER'S RECOMMENDED ACTION:
This project will improve the sanitary sewer system by restoring structural integrity of
deteriorating sewer segments and by removing inflow and infiltration to regain valuable
capacity within the system. Therefore, it is the recommendation of the City Manager that the
City Council adopt Alternative No. 1, as described above.

The City of Ames and Mannatts met on 9/22/2023 to discuss the lining project through the manatts property
Below is the direction given to WHKS to complete the estimate above to assign Costs to the City and Manatts.
MH 1583 - any work is paid for by the city
SAGM 1332 - City to pay 100% of Alt. 1 which is a 15mm liner (Easement agreement must be in place about no stockpiling)
MH 1287 - City responsible for replacement cost up to elevation 913.65 and the cost of a new casting
Manatt's responsible for the cost of the mahole from 913.65 to 937.00
SAGM 1333 - Manatts wants to fill ravine and stockpile over the top. Mannats to pay the difference between Base and Alt. 2
Base price was $100 per foot and Alt. 2 was $200 per lineal foot.
MH 1286 - City responsilbe for replacement up to elevation 923.00 and the cost of a new casting
Manatt's responsible for the cost of the mahole from 923.0 to 937.00
SAGM 1334 - Manatts wants to stockpile over the top. The fill is already at approximately 937.0 elevation
Below are additional thoughts WHKS make while doing the estimate and deciding percentages of responsibility.
The city wouldn't replace the manholes they would only maintain the existing so Manatts should have 50%
MH 1583 and SAGM 1332 are shown and discussed to make it appear the city is paying a higher percentage of cost.
SAGM 1332 is also shown because of the easment and not allowing for stockpiling over the top of that sewer.
