Mound Systems- An Alternative to Septic System

[Tonkos123]

One of the alternatives to the traditional rural septic system leach field is a mound system. In areas where septic systems are more prone to failure due to extremely slow or extremely fast permeable soils, soils with shallow cover over porous bedrock and soils that have high seasonal water table, the mound system is preferred. Mounds are pressure dosed sand filters placed above the natural soil and the discharge is directly let into this soil. Providing additional treatment to the waste water before it enters the natural environment is its main purpose.

The three major components of a mound system are a pretreatment unit, dosing chamber and the elevated mound. A septic tank that removes solids from the waste water is called the pretreatment unit. The septic tank is followed by the dosing chamber and contains a pump that uses the pressure to evenly distribute the waste water over the infiltration surface of the mound. A network of small diameter perforated pipe is placed on the mound which is made up of a soil cover that can support vegetarian and a fabric covered coarse gravel aggregate. The effluent is distributed evenly through the gravel by a network of perforated pipe and it trickles down to the sand media and hence into the plowed basal area or the natural soil. As the waste water filters down through the sand and the natural soil, treatment occurs through physical, biological and chemical means.

Well, it's a nice little description; from a person in India with a record of spamming. I removed the link to a site in India and left the rest in case it inspires any reader to research the subject.
