In rural areas and other places where municipal sewerage is unavailable, septic systems are used to treat and dispose of wastewater that homes produce. Basically, a septic system consists of a septic tank that stores wastewater and collects the separated solid waste, a drain field where wastewater is discharged to and leaches through, and soil that biologically filtrates the wastewater before it contacts the groundwater. If you have a septic system in San Francisco, be sure to inspect your septic tank frequently and to remove the sludge that can build up from use. Contact a professional every few years to schedule a septic tank inspection, a septic tank pumping, or a hydro jet cleaning.
