Some properties in Perth are not connected to the municipal sewer system and instead the buildings are serviced by an On-site sewage system (typically referred to as a “septic system”) which is designed to treat wastewater generated by the use toilets, showers, dishwashers, washing machines, etc…
A on-site sewage system includes a septic tank and a leaching bed and generally both hidden below the soil. As the property owner, it is your responsibility to make sure your on-site sewage system is in good working order. A well maintained and properly working system is critical to your health, the health of neighbours, the health of the ecosystem, and the value of your property investment. Below is some information about proper operation and maintenance of a septic system, how to identify that a septic system may not be working properly and what to do if you do suspect a problem with your septic system.
Do:
- Know where your septic tank and leaching bed are located on your property
- Keep accurate records of sewage system maintenance, pump outs and service calls
- Test your well water at least three times per year for indicator bacteria (spring, summer and fall)
- Have your system inspected by a licensed installer or sewage hauler every few years and pumped out when required (a house typically every three years — some commercial uses may require more frequent inspection and pumping). Best time of year for pump out is summer or fall before the cold weather.
- Clean the effluent filter (located in the tank where it flows to the bed) at least once a year
- Direct surface water/drainage away from leaching bed
- Conserve water use to reduce amount of wastewater needed to be treated
Do Not:
- Enter your septic tank
- Put fats, oils, paints, food waste, chemicals, pharmaceuticals, sanitary products, condoms or anything plastic down the drain
- Use special additives that are claimed to enhance your tank or system
- Use cleaning detergents that are high in phosphorus
- Dig on your property without knowing where your sewage system is located
- Drive or park over your sewage system
- Pave over your leaching bed
- Put an above ground pool over your leaching bed
- Put an outdoor skating rink over your leaching bed
- Plant vegetation over your leaching bed (e.g. garden, flower beds, trees etc.)
- Connect rain gutters, sump pumps or storm drains into your sewage system
- Drain hot tubs or pools into your sewage system
