Recommended Action
I move that the Board of Public Utilities approve Task Order No. 3, AGR 24-04C for the Purpose of the White Rock Sewer Force Main Replacement Project with Dub-L-EE in the Amount of $111,844.49 and a contingency in the amount of $20,000, for a total of $131,844.49, plus Applicable Gross Receipts Tax.
Utilities Manager's Recommendation
The Utilities Manager recommends that the Board approve as presented;
Body
The existing sewer force main that conveys sewage from the Rio Bravo Sewer Lift Station to the receiving gravity sewer line in White Rock has been observed leaking where the force main is installed in a steel casing above ground across a small canyon in White Rock. An engineering consultant was hired to evaluate the structural integrity of the steel casing and its associated support structures and investigate the leak. The casing was found to be structurally sound and the leak was from the pipe inserted inside of the casing. This project will replace the existing 4" pipeline with a new 3" HDPE line inside the steel casing. The broken guards on the casing will be replaced separate from this task order.
Alternatives
If the task order is not approved, the project will be budgeted again next year due to the severe sewage spill that would occur if the pipeline were to fail.
Fiscal and Staff Impact/Planned Item
The project has been budgeted in the amount of $180,000 in fiscal year 2025.
