Conservation is always the most economical and environmentally beneficial place to begin.

You might find that your landscape doesn't require as much water as you've been giving it, or that there are easy ways to greatly reduce the amount of water your household uses.

If you are not able install an actual graywater system, you can still reuse water by collecting shower water in a bucket as the water heats up and using it to water your plants.

Determine which fixtures in your home are candidates for graywater capture. Washing machines are usually the easiest place to begin. Another potential fixture for graywater capture is the shower and bathtub faucet. In combination with your flow calculations, this analysis will help you determine how large your graywater distribution system will need to be.

Read about types of graywater systems and decide which is best for you. Draw a sketch of your proposed system. Find an installer or install the system yourself.

Operate and maintain your system. Graywater is a purely local water supply -— it is both produced onsite and used onsite as close to the point of production as possible. If graywater harvesting is appropriate for a site, it can provide a substantial quantity of local water for reuse.

Some systems function without treatment, and others utilize technologies as complex as real treatment plants on a miniature scale. Many systems that a home or multi-unit owner can download commercially produce a filtered, disinfected product.

Greywater Resources

While current technologies around the world support a wide range of graywater sources and uses, not all are legal in California, as previously noted. Laura Allen makes the point that all manufactured systems use plastic, pumps requiring electricity, maintenance and eventual replacement. If you have plants to water, use untreated greywater outside — you'll save money, time, and energy.

Their practicality and cost effectiveness depends upon advances in technology. As Art Ludwig points out, it is best to use graywater as close to the source and as soon as possible. Manual bucketing is also used to capture graywater from a shower or sink after use. Both forms of bucketing are widely practiced and are common and promoted practices in Australia. It is generally not covered by any ordinance or code where it is being encouraged. Bucketed greywater can be reused for irrigation of gardens, lawns and outdoor pot plants.

Laundry-to-Landscape Laundry to landscape LTL graywater systems are one of the most simple and least expensive graywater systems that can be installed in single and multi-residential buildings.

In all likelihood, they are the most commonly used system in California, along with manual bucketing. The basic concept is to divert graywater by a hose connected to the outlet of the clothes washer, and running this hose to reach the sub-surface irrigation area.

Adjustable valves are then added as part of the distribution system to allow the graywater to empty into mulch basins around trees and plants. These systems are useful where water is needed for irrigation or where pervious surfaces allow infiltration.

It is a cost-effective retrofit system, and renter-friendly.

It can irrigate areas level with or slightly uphill from the washer. This is the system I recommend most often, usually in combination with a Branched Drain or Green Septic system.

Older top loading clothes washers use approximately 30 to 45 gallons of water per load. High efficiency clothes washers range from 3 to15 gallons of water per load, 12 gallons being more or less typical according to AWWA.

Press Release: Create an Oasis with Greywater 5th Edition

A family of four using a standard sized clothes washer will generate more than approximately loads per year. This equates to a non-efficient washing machine consuming approximately 12, gallons of water annually and a high efficiency approximately 3, gallons a year.

Accordingly, approximately 30 GPCD is produced. With 37,, people living in the state, 1,,, gallons or approximately AF of graywater is produced per day from residential clothes washers in California. In reality, only some percentage of these nearly AF gallons that Californians produce in clothes washer use will be appropriate for graywater use, due to loads that include chemicals such as bleach and fabric softeners, as well as materials soiled with feces, reducing the probable total available for graywater.

Bathroom Sink, Shower, Bath to Exterior Landscape Graywater can be distributed from the bathroom sink, shower or tub into the landscape, generally through a gravity-fed branched drain system.

Graywater drains through a series of branching pipes and is dispersed into the landscape via mulch basin outlets.

This system alters the existing plumbing and requires a permit. This is because, unlike laundry to landscape, diverting graywater from a shower or tub requires cutting into existing plumbing. The state of California requires a permit for these types of diversion systems.

System costs can range from a few hundred dollars if installed by homeowner to a few thousand dollars if installed by a professional.

Create an Oasis with Greywater and Builder's Greywater Guide

Graywater from showers, sinks, or laundry is directed to a temporary holding tank and then pumped to the landscape, which can be uphill of the graywater source s. This system usually alters the existing plumbing and always requires a permit; an additional electrical permit might also be required for the outlet into which the pump is plugged.

This is again with the caveat that not all of these water sources will be usable for graywater due to contamination from chemicals or feces. Systems must still meet the design and construction standards found in the regulations. This is very effective use of graywater in a residential building, particularly multi-unit buildings.

However, it is very difficult to install an indoor toilet flushing graywater system in California. In addition to permitting difficulties, the requirements of meeting water quality standards set out in Title 22 standards for blackwater treatment, as well as regular monitoring, is more than most home owners or multi-unit apartment or condo managers can take on.

This may be reused for other purposes, especially landscape irrigation.

This is the definition common in Europe and Australia. Some jurisdictions in the US exclude kitchen sink water and diaper wash water from their definition of greywater. These are most accurately defined as "dark greywater " Why use greywater? It's a waste to irrigate with great quantities of drinking water when plants thrive on used water containing small bits of compost.

Unlike a lot of ecological stopgap measures, greywater reuse is a part of the fundamental solution to many ecological problems and will probably remain essentially unchanged in the distant future. The benefits of greywater recycling include: Lower fresh water use Less strain on failing septic tank or treatment plant Better treatment topsoil is many times more effective than subsoil or treatment plant Less energy and chemical use Groundwater recharge Reclamation of otherwise wasted nutrients Increased awareness of and sensitivity to natural cycles Healthy fruit from sanitary irrigation of edible landscape Why does greywater matter?

A low flow showerhead can save water with less effort. A septic system can treat greywater almost as well. But when you look at the whole picture—how everything connects—the keystone importance of greywater is revealed.

Ecological systems design is about context, and integration between systems.

The entirety of integrated, ecological design can be reduced to one sentence: do what's appropriate for the context. Ecological systems—rainwater harvesting, runoff management, passive solar, composting toilets, edible landscaping—all of these are more context sensitive than their counterparts in conventional practice; that's most of what makes them more ecological.

Greywater systems are more context sensitive than any other man-made ecological system, and more connected to more other systems. Many people and organizations instinctively recognize that greywater is the ideal test case for the transition to a new way of regulating and building that is appropriate to a post-peak resource, mature civilization.But when you look at the whole picture—how everything connects—the keystone importance of greywater is revealed.

It can irrigate areas level with or slightly uphill from the washer. It is remarkable how much information was packed into these two short publications, which can be read in a sitting.

Clothes Washer Final-to-First Wash Cycle The rinse water from a previous load can be used to supply the first wash cycle of the next load. Older top loading clothes washers use approximately 30 to 45 gallons of water per load. You might find that your landscape doesn't require as much water as you've been giving it, or that there are easy ways to greatly reduce the amount of water your household uses. Related aspects of sustainable water use are addressed on one of the detailed appendices, including an examination of the household water cascade, rainwater harvesting, and composting toilets.
