Treatment of rainwater and gray water recycling: drinking water savings of between 30% and 45 %

Greywater is water from the kitchen, laundry, the bathroom, toilet, sink, the shower, etc. It's waters that, at first sight, may be useless and re-use achieved decrease spending on drinking water, as well as reduce wastewater discharge.

The solution is to debug from grey water for personal hygiene (showers, tubs and toilets) for use in applications where there is no drinking water (toilets, washing, cleaning, irrigation, etc.).

There are systems to reuse water very popular grey for use in single-family homes, neighbors, sports facilities and football pitches or pools, hotels and universities communities. These facilities consist of a few independent pipes through which circulate greywater reaching about deposits, where carried out a cleansing treatment. Thanks to cleansing, water can be recycled to fuel tanks for toilets, Garden irrigation or exterior cleaning.

Greywater reuse equipment is installed in the basement or attic, with the corresponding Dewar who knowingly and try the waters. Also install the piping needed to collect water shower and washbasin, and they lead the water to be treated; and on the other hand pipes that convey the treated water into the tank of the toilet and a mouth watering, if it were necessary.

Greywater reuse systems can achieve savings of between 30% and 45% of drinking water. Reusing water decreases the costs of drinking water and wastewater, protects groundwater reserves and reduces the burden of wastewater.

These systems can be incorporated into any building, and it is estimated that each household can save about 45 liters of drinking water and waste water per person per day; Hotel and sporting facilities, savings can reach 60 litres per person per day. The installation of a system of reuse of greywater for a family of 4 people can hang the 1,100 euros; for homes or existing facilities, price is costly, because you must add the price of the work, therefore recommends implementing them using domestic reforms.

Greywater reuse benefits include less use of fresh water, a lesser flow septic or plants of treatment, a highly effective purification, a solution for those places where cannot be used another type of treatment, less use of energy and chemical pumping and treatment, the possibility of planting plants where there is no other type of water, or the recovery of nutrients that are lost.
