Tiny Alloway Township
Saves Big with
No one will ever mistake Alloway, New Jersey, for New York or Philadelphia. Alloway is a tiny town (population 2,500) located in the Southwest part of the state just a few miles from the Delaware River. Yet, Alloway has something that even major cities can only dream of – a state-of-the-art sewer system that’s low maintenance and environmentally sound.
VACUUM SEWERS 101
Homeowners typically don’t notice the difference between a vacuum sewer and any other collection system. Gravity lines transport sewage from the home just like they do in a gravity system, but at the street or property line, the sewage empties into a buried valve pit. Inside the valve pit is a patented AIRVAC pneumatic valve. It requires no electricity, so there are no electrical lines to worry about and the valve will function even during a power outage. When 10 gallons of wastewater accumulate in the pit, the valve opens automatically and differential air pressure propels the contents into the vacuum main.
Installing AIRVAC sewers rather than gravity sewers saved Alloway taxpayers approximately $1 million, or about $180 annually for each user over 40 years. Saving money was an extremely important consideration, but there were other significant benefits, as well.
