Decentralized Systems Technology Fact Sheet: Recirculating Sand Filters
U.S. Environmental Protection Agency, Office of Water

A recirculating sand filter (RSF) system is a modified version of the single-pass open sand filter. Designed to alleviate the odor problems associated with open sand filter, RSFs are a viable alternative to conventional methods of treatment when soil conditions are not conducive to treatment through percolative beds/trenches. This fact sheet illustrates and describes the RSF system and how it removes contaminants from wastewater. The fact sheet includes two case studies and discusses advantages and disadvantages, design criteria, performance, operation and maintenance, and costs.

Decentralized Systems Technology Fact Sheet: Septage Treatment/Disposal
U.S. Environmental Protection Agency, Office of Water

The 1990 Census estimated the number of housing units with septic tanks or cesspools in the U.S. at 24.6 million, with these systems generating approximately 5.5 billion gallons of septage each year. Septage-the liquid and solid material pumped from a septic tank, cesspool, or other primary treatment source-is classified according to the environment in which it is generated. This fact sheet focuses solely on domestic septage, delineating three basic ways septage is treated and disposed:

• land application,

• treatment at wastewater treatment plants, and

• treatment at independent septage treatment plants.

Septage characteristics are listed, and two tables provide data for parameters and septage sources. Options for surface application, subsurface incorporation, and burial are summarized in relation to design criteria.

Decentralized Systems Technology Fact Sheet: Septic Tank Leaching Chamber
U.S. Environmental Protection Agency, Office of Water

A leaching chamber is a wastewater treatment system consisting of trenches or beds, together with one or more distribution pipes or open-bottomed plastic chambers, installed in appropriate soils. These chambers receive wastewater flow from a septic tank or other treatment device and transmit it into soil for final treatment and disposal. They offer an alternative to the conventional drainfield, providing under certain conditions, more efficient effluent treatment, little maintenance, and reduced drainfield costs. This fact sheet describes the leaching chamber system and summarizes common modifications, applicability, advantages and disadvantages, design criteria, performance, operation and maintenance, and costs. Photographs and data tables complement the text.

Decentralized Systems Technology Fact Sheet: Septic Tank-Soil Absorption Systems
U.S. Environmental Protection Agency, Office of Water

An estimated 30 percent of all U.S. households use onsite treatment methods with the septic tank/soil absorption system being the most popular. The septic tank-an underground, watertight vessel installed to receive wastewater from the home-is designed to:

• allow solids to settle and separate from the liquid,

• allow for limited digestion of organic matter, and

• store the solids while the clarified liquid is passed on for further treatment and disposal.

Though septic tank effluent can be treated in a variety of ways, this fact sheet describes how effluent wastewater is distributed into a subsurface soil absorption area or drainfield. The fact sheet discusses applicability, advantages and disadvantages, design criteria, performance, operation and maintenance, and costs.
