Comprehensive Water System Improvements
Weston & Sampson provided engineering design, permitting, and construction services for a water system improvement project that was needed to address low pressure issues in the higher elevation of the water system and address water leakage at the existing 1912 0.5-million gallon (MG) concrete reservoir.
The project received the American Council of Engineering Companies Vermont (ACEC/VT) 2011 Engineering Excellence Award in Category C: Water Supply/Treatment. The project included:
- Increasing pressure to the distribution system with a new high service area
- Hydraulic modeling evaluation of the water system to assess an innovative approach to increasing water storage while also providing required contact time prior to the first customer
- Construction of a new 415,000-gallon capacity pre-stressed concrete water storage tank
- Approximately 1,500 feet of new 12-inch ductile transmission water main (cross country)
- Creation of an 1,800-foot cross country access road through a wooded hillside to the new water storage tank
- Installation of three pressure-reducing valves to segregate the new high service system
- Water line crossing under Park Street/Route 15A via horizontal direction drilling
- SCADA and control upgrades at each water facility
- Demolition of the existing 0.5-MG water storage tank
- Permitting, which included VTrans, Wetlands, Stormwater, Categorical Exclusion, ACT 250, Zoning, Water Supply Division, U.S. Army Corps of Engineers, and Archaeological
