WASTEWATER FACILITY PLANNING
POWNAL, VERMONT
PROJECT HIGHLIGHTS
- Conducted a detailed and extensive alternatives analysis to determine whether goals
could be addressed through a de-
centralized on- site wastewater system.
- Analysis included individual on-
site and cluster on- site wastewater systems, as well as direct discharge alternatives.
- Six different trailer parks have inadequate land area for community on-
site wastewater systems. Many homes have small lots with inadequate isolation distance for functional on- site systems.
- Conventional wastewater collection and treatment system demonstrated to be the most
practical and cost-
effective option.
- Through close coordination with US EPA effort to clean-
up a superfund site, wastewater treatment facility will be located on a brownfield site saving $750,000 in construction costs.
- Proposed project will encourage development within three population centers and discourage random and scattered growth outside these areas. Town can easily control future connection to force mains and pump stations.
- Proposed project includes:
- 62,000 lf of gravity sewers
- 51,000 lf of sewer force main
- 11 wastewater pump stations
- SBR treatment facility with ultraviolet disinfection and containerized sludge composting
