Lift Station No. 3 Upgrades
Lift Station No. 3 is underneath Highway 395.
DESCRIPTION
| PROJECT ID: | S 15.0 |
| ESTIMATED COST: | $450,000 |
| ACTUAL COST: | $1,407,783.49* |
- Extends a gravity line to Lift Station No. 6, which is also in poor shape (see W 13.0). Extending the line under Union Pacific Railroad tracks is more cost effective than replacing both lift stations
- Traffic control will be necessary
* Challenges encountered with boring under the railroad required demobilization and a significant change in the equipment necessary to complete the job, which led to significant cost increases from the original estimate.
WHY IT’S NEEDED
Lift Station No. 3 was built in approximately 1981 and located underneath Highway 395. The pump and electrical systems need to be replaced.
