Background:
Approval of this item will ratify the agreement with Wastewater Transport Services, LLC for the emergency wet hauling (tanker trucks) from the emergency repair of the 24-inch Ductile Iron Force Main located near FM 2094 & Davis Rd in an amount not to exceed $148,153.67.

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.
Wastewater Transport Services’ wet haul efforts were necessary to supplement the large volume bypass needed to maintain service for the duration of the repair activities. Traditional bypass methods are not possible for this location due to the lack of nearby gravity sewer mains large enough to accept the volume of flow. Wastewater Transport Services utilized multiple 7,000 gallon 18-wheeled tanker trucks to transport approximately 220 loads over a 7-day period (July 25, 2024 through July 31, 2024). D. Wagner Construction Co., Inc. also included a lessor...
