The Benefits of an Effluent Sewer
Because only liquid effluent is pumped intermittently, using small and energy efficient pumps (generally the PF100552 half horsepower pump is used) the electricity cost to the home owner is minimal.
Effluent collection lines are generally much smaller than standard sewer lines, typically they measure 50 - 100mm in diameter and can be shallow buried following the contour of the site. This reduces install costs as well as the impact on the environment
No expensive pumping stations are required, and the water tight effluent sewer system does not require manholes.
In systems built to serve new subdivision developments, the cost of the on-lot equipment is taken care of by the homeowner, so up front investment by the developer or local authority is minimal.
Service can begin as soon as the first home in the subdivision is connected. There is no minimum flow required for an effluent sewer.
Sludge management is greatly reduced through the natural ,passive ,anaerobic digestion in the on-lot interceptor tanks, simplifying the design of the treatment plant and minimising whole-of-life costs.
As primary treatment takes place at each home or business, abuse of the system, such as disposal of chemicals, usually affects only the household responsible.
