Will the discharge from a home dishwashing machine into a private septic system harm the septic tank or drainfields? This document explains how to extend the life of the septic system by being careful about what goes into it.

A Guide to Home DISHWASHER Machines - and Septic Systems

DISHWASHERS - and Septic Systems

Does a dishwasher water volume overload and harm the septic system?

The volume of water from home dishwashing machine use should not be a problem with a normal septic system in good working order.

However as we discussed at "Washing Machines", in some conditions you should avoid emptying dishwasher discharge into the septic system:

  • Drainfield capacity may limit dishwasher use: if the absorption system (leach field, drainfield) has limited capacity to absorb effluent
  • A failing drainfield and use of dishwashers: if the absorption system is showing evidence of failure, such as effluent coming to the surface of the property or backing up into the building (nonetheless you need septic field investigation and repair)

Does dishwasher detergent harm the septic tank or septic system drainfield?

The volume of dishwasher detergent entering the septic system is so low as to be very dilute when it enters the septic tank, dilute enough that it is not going to harm the septic tank bacteria at normal levels of residential dishwasher use.

However many if not most dishwasher detergents contain phosphates or nonylphenol ethoxylate surfactants. Surfactants are what make detergents effective in lifting soil particles off of a surface (a dish in the dishwasher or a shirt in the washing machine).

Dishwasher detergents do not make a high level of suds inside the dishwashing machine. If you've ever made the mistake of putting normal dish soap into a dishwasher (as did this author) you know what a disaster will ensue - with sudsy soap overflowing out of the dishwasher and across the floor. Dishwashers rely on surfactants, high water temperature, and time spent spraying across the dishwasher contents to clean them.

Dishwasher & Laundry Detergents Containing Phosphates & Surfactants May Contaminate the Environment

Even if they don't kill off your septic tank or drainfield bacteria, surfactants and phosphates that run through a dishwasher ultimately enter ground water and surface water may also become contaminated.

Surfactants in dishwasher detergents (and from any source) are toxic to fish, basically suffocating them by interfering with the ability of the fish's gills to absorb oxygen from water.

Phosphates in dishwasher detergents pass through the septic system (or municipal wastewater treatment system) and enter surface water causing very high growth rates of algae. The algae growth, in turn, suffocates fish and other life in rivers, streams, lakes, and ponds. The rapidly growing "dead zones" at the edges of major water bodies around coastal areas of the U.S. and other countries are blamed on surface runoff that contains phosphates, (probably largely from agricultural use).

According to Cliff Davies, a U.S. EPA engineer reported in the New York Times the level of phosphates in dishwasher detergent has been significantly reduced since the 1970's.

But Mr. Davies was unable to identify specific dishwasher detergent products or brands that were high in surfactants or phosphates, and the Times article reported that the U.S. EPA "Design for the Environment Program" which he administers does not track products that are problematic.

The EPA does, however, list dishwasher detergent products whose manufacturers report to the EPA that they use the safest chemicals. The EPA does not perform tests to confirm the accuracy of product claims.

In sum, consumers who want to minimize their contribution to environmental pollutants by their choice of dishwasher or washing machine cleaning products may want to purchase products listed by the EPA's "Design for the Environment Program" but the listing designation does not appear to be supported by independent testing nor publicly available data. As of February 2009 it's the best we've got.

Install a Drywell to Handle Dishwasher Drainage to Protect the Drainfields from Overload

One option is to install a separate graywater system (greywater) or drywell to receive water from the dishwasher. If you are considering this step, consider connecting both dishwasher and clothes washer to a common drywell.

At some properties with very limited septic capacity, a large drywell may be installed to handle additional gray water from other building fixtures such as sinks and showers. See DRYWELL DESIGN & USES for additional information.

This comprehensive guide filled with case studies can prevent that. Master plumber R. Dodge Woodson packs this reader-friendly guide with guidance and information, including details on new techniques and materials that can economize and expedite jobs and advice on how to avoid mistakes in both estimating and construction. Chapters cover virtually every aspect of wells and septic systems, including on-site evaluations; site limitations; bidding; soil studies, septic designs, and code-related issues; drilled and dug wells, gravel and pipe, chamber-type, and gravity septic systems; pump stations; common problems with well installation; and remedies for poor septic situations. Woodson also discusses ways to increase profits by avoiding cost overruns.
  • Country Plumbing: Living with a Septic System, Hartigan, Gerry: $ 9.95; ALAN C HOOD & TP; Quoting an Amazon reviewer's comment, with which we agree--DF:This book is informative as far as it goes and might be most useful for someone with an older system. But it was written in the early 1980s. A lot has changed since then. In particular, the book doesn't cover any of the newer systems that are used more and more nowadays in some parts of the country -- sand mounds, aeration systems, lagoons, etc.
