The manhole should have a concrete coverwith an earth covering of at least 6 inches, but not more than 12 inches. If the top of the tank is more than 12 inches below
How long do septic tanks last?
Septic tanks are built using corrosion- and decay-resistant materials. If installed properly, they will be watertight for a long time (30 years or more). Precast reinforced concrete tanks are the most common. However, tanks also may be constructed using poured-in-place concrete or built from concrete blocks with the cores filled with concrete rein-forced with rebar. Concrete block tanks must be sealed with at least two coats of concrete plaster. Fiberglass and durable plastic septic tanks also are available. They must be installed by care-fully following the manufacturer’s instructions so they will withstand soil and water pressure.
What is an outlet baffle?
Inlet and outlet baffles are criti-cal parts of a correctly installed septic tank (Figure 2). The inlet baffle directs incoming sewage downward into the liquid zone of the septic tank. The outlet baffle allows sewage effluent to flow out of the liquid zone, retaining the scum in the tank. Many new septic tanks have a removable filter incorporated into the outlet baffle. The filter prevents nondecompos-able materials (condoms, sanitary napkins and other items) from reaching the drainfield.
How far away should a septic tank be from the house?
The septic tank should be at least 10 feet away from the house. The tank should be aligned straight out from the point where the discharge sewer line leaves the house. Installing the tank so it is level, with no slope in any direction, is important. For pump-ing and cleaning, the septic tank should be situated near a drive-way or other access road. Most septic pump trucks carry between 50 and 100 feet of hose, so the tank should be accessible from this distance. Select a location away from high vehicle traffic areas. Never locate septic tanks under sidewalks or patios where the tank is inaccessible for pump-ing.
What is the basal area of a mound?
The basal area of the mound (contact area of the fill sand with the existing soil) determines all the other mound design parame-ters. The basal area is determined by the texture of the existing soil. For slowly permeable clay and clay loam soils, use a design ef-fluent loading rate of from 0.20 to 0.25 gallon per day per square foot.
Does a soil absorption system work all year?
soil absorption system has to work all year. That means it must infiltrate effluent during wet springs and cold winters. Effluent from the septic tank is about 99 percent water but it also contains biological material (small particles). Additional treatment of the biological material occurs in the soil absorption system (Figure 9). The area of soil absorption must be sized so it can infiltrate the daily wastewater flow from the house, as well as effectively decompose the biological materi-als in the effluent.
What is a filtration system?
Filtration systems physi-cally trap suspended solids in the wastewater and provide a me-dium to speed up the process of decomposition. They are like mini versions of a typical municipal waste treatment system. Filtration systems can be part of the septic tank or just downstream from the septic tank. Sand filters have been used for many years and they can be configured as single-pass (waste flows through only once) or multiple-pass systems. Filtration systems that use peat have come on the market in the last 10 years and are used as a single-pass system. Other filtration systems use artificial or synthetic materials to filter the effluent and treat the biological solids. These mostly are multiple-pass systems. In some parts of the U.S., artificial wetlands have been used to treat household wastewater. However, research on artificial wetlands in the northern-tier states has not been successful.
