Collector lines move
storm, influent, sanitary, footing, and/or downspout water
from home and businesses.
Collector, trunk, and
interceptor lines are interconnected by overflow release
devices which in most cases result in environmental contamination.
Interceptor lines may
carry storm, influent, sanitary, footing, and/or downspout
water to treatment plant.
Increase in fluid volume
as homes and buildings connect to the system.
A sewerage system operating
near capacity may have frequent overflow problems causing
contamination and backups.
Intermixing of sanitary
effluent with storm, infiltration, footing, and downspout
water will be eliminated with the installation of the 4E®
system.
In many cases separate
storm drains have been installed usually running parallel
to the original sanitary combined line. However in most
cases, severe inflow from downspout, footings drain and
infiltrated water still plague the original line. In many
cases the separated flows are recombined prior to entering
the treatment facility causing more over flows, environmental
damage, and increased treatment costs.
