This document discusses the Septic Effluent Dosing Control for Septic Media Systems. When using a septic media filter system, effluent treatment is by both actual filtration and ultimately by a biochemical process as the filter "matures" and includes its own biomass. Both natural media filter septic systems (such as sand, gravel, or peat) and synthetic media filter septic systems (foam cubes, glass, slag) are used, and both single-pass and effluent recycling systems may be employed.

Septic Effluent Dosing Control for Septic Media Systems

Sketch of a Rigid Pipe Dosing System - EPA A septic effluent dosing system which passes on effluent at the appropriate rate is part of the design of a media filter septic system. Dosing may be controlled by sensors and an electric pump or by gravity and a bucket tipping system.

Septic effluent dosing control is achieved using pumps controlled by timers and level sensors which assure that effluent is applied in sufficiently small doses to permit effective treatment.

Septic Dosing Systems, Pressure Dosing or Gravity Dosing

Dosing systems permit the septic system drain field to rest between effluent doses and, depending on design, may alternate use of drainfield sections. Two broad types of dosing systems are Gravity-Dosing (effluent flows from an effluent tank to the absorption system by gravity) or Pressure-Dosing (effluent is pumped from a dosing chamber to the absorption field).

See Gravity Dosing Septic Systems
and Pressure-dosed Drainfield Septic Systems for details about dosing system design, installation, and product alternatives for each of these dosing system types.
