Grey water storage tanks

Grey water storage pumps are now for domestic use.  Grey water from daily household activity is pumped into the storage tank where it can be used later  to flush toilets or to water the grass and gardens.  The other good quality is that the storage tanks is that it lowers the demand on the water treatment plants.  But re-using grey water has it’s downfalls too. 

“GREYWATER - water generated in the shower, bath, hand-basin, and laundry. The water from the spa requires separate treatment because of its quality and large volume and needs to be discharged separately. Greywater has a highly variable chemistry depending upon the behaviour of the residents and the volume of water and the chemicals used. Just consider for a moment what happens with body sweat, hair, skin, bacteria from the body and the other bits of us that we wash down the sink – about 2 kg of skin, hair and body exudates per person per year. The greywater, therefore, has not only solids, greases and dissolved salts but also foreign particles such as soil, sand, bone, soap and the minerals in the original water. Many of the chemicals we use are detrimental to plants and soil so control over the quantity that enters greywater need to be considered when greywater is to be used as an irrigation resource. It’s not that we shouldn’t reuse greywater, just that we must understand some of the consequences of not using it wisely.”
