AERATED LAGOON WASTEWATER TREATMENT FACILITY UPGRADE
RICHFORD, VERMONT
PROJECT HIGHLIGHTS
- Major cost savings of over $2 Million because of innovative engineering and construction management approach.
- $360,000 upgrade solution (actual total project cost) vs. $2,500,000 lagoon reconstruction from preliminary engineering report.
- Fast track project with design and construction completed in 6 months.
- First Vermont municipal wastewater project to utilize engineer led construction management.
- Engineer pre-
ordered critical items with long lead- times.
- State-
of- the- art materials for removable aeration diffusers and high- efficiency aeration blowers with variable frequency drives.
- Critical sequencing of work included temporary floating baffles and removal of sludge
from both lagoons while on-
line.
- Simple, yet effective, state-
of- the- art high efficiency floating aeration diffuser systems and new floating baffles that are all easily retrievable without process interruption or emptying of the lagoons.
- Fixed location suspended diffusers for same depth control from floating laterals.
- New design within existing lagoons meets all current design standards.
- Aeration capacity increased five fold and complete mix zone added for improved process treatment.
- All aeration piping, diffusers and baffles are easily retrievable without process interruption or emptying of lagoons.
- Garry Shover, Richford Wastewater Superintendent, received the 1999 “Wastewater Operator of the Year” Award from the Green Mountain Water Environment Association for his efforts in this project.
