All typical septic systems have a septic tank, which is usually a sizable buried rectangular or cylindrical box made of cement, fiberglass or polyethylene. Wastewater from all plumbing fixtures drains in to the septic tank. Heavy solids settle to underneath where bacterial action produces digested sludge and gases. Lighter solids that float such as grease, oils and fatty acids, rise to the top and form a scum covering. Systems designed before 1975 in King County will often have single compartment tanks. Those built from 1975 and on are usually two compartment tanks. This is important to know when getting the septic reservoir serviced, as both compartments of an two-compartment tank have to be pumped. We are also well-versed in the creation and supply of concrete rainwater tanks and Ri-Treat systems, which we've provided to an enormous variety of home and commercial structure assignments throughout South Australia and the Northern Place. As with our septic container designs, the products are suitable for many personal and commercial properties, and we are happy to discuss their consumption and application together with you.
You can also harm your septic system by doing a large quantity of laundry lots in a brief period of time. In standard septic systems, sturdy materials settle in the fish tank, while effluent moves out in to the ground. In the event that you put more water in to the septic system than it is built to deal with, the high level of water will flood one's body and can flush solids out of the tank into the drainfield. An average washing machine may use up to 62 gallons of water per wash weight.
Shown below is an example standard installation with two drywells in series - bringing sewage in through the lid. Top loading (with vent) ensures maximum surge capacity for the drywell. Please note that venting your leaching pit (or any septic field) is most highly recommended... lack of venting at both ends of lateral lines is the best reason behind leach field inability (after lack of proper two compartment filtered septic container). Oxygen keeps the drainage pit dry and the ground around it healthier. Freezing is almost never, if ever, a difficulty with operating sewage normal water underground, nevertheless, you can always cover the vents in deep winter, if you need to. We provide all of the fittings pictured with your set (san tee, riser, coupler, vent and geotextile textile). The geotextile fabric is roofed for set up above the gravel covering. It continues backfill ground from clogging the gravel and is essential to extending the life span of your leach pit.
In lots of council districts (e.g. Sunshine Coast) septic systems have been banned and have to be replaced with much more expensive small size sewage treatment systems that positively pump air in to the container producing an aerobic environment. Septic systems need to be substituted with any new building applications, regardless of how well the old system performed.
It compensates to look after your tank (see What Not to Flush, below) and invest in septic tank pumping periodically so the necessary bacteria don't pass away, shutting down the natural machine. At these times, sludge builds up and flows in to the drainfield, where it clogs up the system. Before very long, you have a sewage back up, septic container problems, and a major headache.
