Water Storage Tank Design

Williamstown, Vermont

Preliminary engineering study, final design, and bid and construction services for this major improvement to the Williamstown water system. The project included construction of a single chamber, pretensioned, precast concrete, circular 675,000-gallon storage tank, draining and removal of existing reservoirs from service, interconnecting piping to utilize existing well pumps, and connection to existing distribution system. New storage tank was sited to boost water pressure to the upper portion of the distribution system, including the high school. To avoid excessive pressures in the lower portion of the distribution system, two pressure zones were created using strategically located pressure reducing valve stations.

Services included topographic survey, subsurface exploration, final design and specifications, hydraulic modeling of the distribution system, permitting, cost estimating, bid phase and construction phase services, and project meetings. Special services include documentation to the Water Supply Division and applications for State Revolving Funds.
