Monitoring and Maintenance FAQ
A traditional onsite sewage system or “standard gravity” onsite sewage system may only need limited amounts of maintenance. The maintenance of a standard gravity onsite sewage system may be limited to pumping of the septic tank as needed.
In comparison to the standard gravity onsite sewage system the modern day next generation or “alternative” on-site sewage systems may require:
-Septic tank inspections, pumping if necessary of the septic tank.
-Inspection of the pump tank (if present) which may include checking floats, cleaning screens and pumping if necessary.
-Inspection of an aerobic treatment unit (if present).
-Cleaning the filter within the aerobic treatment unit (if present); cleaning and inspecting the aeration device.
-Inspection of the lateral drain field lines for levels of effluent (ponding); flushing lateral pressure distribution lines (if present).
-Inspection of the sand filter pretreatment device and flushing of the lateral pressure lines within the sand filter.
-Inspecting mound systems noting effluent seepage, and ponding (if present).
-Inspecting and cleaning any disinfection unit components and replacing parts as necessary.
The first reason is to protect the health of your family, your neighborhood, and the environment. When sewage systems fail, inadequately treated household wastewater is released into the environment. Any contact with sewage can pose significant health risks. Untreated wastewater from failing sewage systems can also contaminate nearby wells, groundwater,streams, marine water and shellfish.
The second reason is cost. Failing sewage systems are expensive to repair or replace. It typically costs between $9,000 to $18,000 or more to replace a failing sewage system with a new, onsite sewage system.
Lastly, proper maintenance of your sewage system protects the financial investment you have in your home and your neighborhood. Failed sewage systems can cause property values to decline. Often, building permits cannot be issued, or real estate sales delayed, until systems are repaired or replaced.
