The simplest type of greywater use is to collect water in a dishpan as you handwash dishes, and then toss it over your flowerbeds or fruit trees. This is a wonderfully simple, inexpensive way to tap into greywater, but with just a little more effort and expense, you can capture much more water.

Greywater is household wastewater from bathroom sinks, showers, tubs and washing machines; it has not come into contact with faces or passed through a toilet. Some intrepid homeowners recycle their greywater by using it to water their lawns or gardens or by using it to flush their toilets. The greywater can be treated first, or it may be used untreated; under no circumstances, however, should it contain bleaches, dyes, bath salts, fabric softeners or detergents containing boron — an excess of boron is toxic to plants.

1. All required laundry detergents and auxiliary washing preparations are fed into the line over a dosing system by computer control as well as the water is added.
2. The washing water is thermally and biologically processed after the washing operation, so that the cleaned water can be fed back again into the washing circulation process. Therefore, the laundry procedure does not generate any wastewater.
3. The process exhaust air of the washing operation is being used to produce energy – it is re-fed into the process (laundry line, dryer) again as steam for recovering heat.
4. A thermal afterburning system emits the waste exhaust air after treatment as „clean air“to the environment. The exhaust air from the drying process is used for recovering heat for the dryer. Waste exhaust air is being emitted as “clean air” to the environment after the treatment in a regenerative afterburning system.
5. In order to build the LWR you need to have room directly (or nearly) above your washing machine for the tank. You also need a way to secure the tank safely, because when full it will weigh more than 250 pounds.
