Comprehensive System Improvements

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
