Title
Consider and take action on a resolution to ratify the contract with D. Wagner Construction Co., Inc. for the emergency repair of the 24-inch Ductile Iron Force Main (FM) from East Main Lift Station (LS) located near FM 2094 & Davis Rd in an amount not to exceed $119,101.60 (Director of Public Works)
Background:
Approval of this item will ratify the contract with D. Wagner Construction Co., Inc. for the emergency repair of the 24-inch Ductile Iron Force Main (FM) from East Main Lift Station (LS) located near FM 2094 & Davis Rd in an amount not to exceed $119,101.60.
On July 24, 2024 a substantial sanitary sewer leak was identified near the Clear Creek Intermediate School, just north of the Genco Canal Bridge on FM 2094. The leak surfaced near the curbline of the eastbound lanes and within the median and was immediately associated with the 24-inch FM from the East Main Lift Station (LS).
After evaluating the magnitude of the failure and its potential disruption of sanitary sewer service, the repair was declared an emergency. The East Main LS and its’ 24-inch FM was constructed in the early 80’s and collects and conveys wastewater from 12 lift stations in the City’s eastside service area. This facility conveys the second largest volume of wastewater from the City’s general benefit lift stations and is the most difficult to bypass pump for emergency repair conditions.
The actual leak was found directly under the eastbound lanes of FM 2094. This required the removal of a substantial amount of TxDOT roadway to complete the excavation of the suspected leak location. The top of the ductile iron FM was found to be in a severely deteriorated condition due to age and the corrosive wastewater environment.
The replacement of this aging FM has been in the City’s Capital Improvement Program (CIP) for many years and the design for the project was 95% complete at the time of this failure. Due to the condition of the failed FM and the concern for similar failu...
