Rain brings benedictions

Rain water tap for garden irrigation (openPR) - everyone of us uses on the average about 135 litres of drinking water, but of it only three litres on the day for drinking and cooking. One can replace more than half of daily pro head drinking water consumption by rain water simply. For Klospülung, laundry washing, cleaning and garden irrigation also rain water is sufficient. The rain water use preserves the environment and the household cash.

Water - the source of the life

Over 97% that altogether approximately 1.4 million Kubikkilometer water on earth are for humans ungeniessbares sea water. Of most is firmly bound the remaining scarcely 3% fresh water, in the ice of the poles and glaciers. The freely usable fresh water portion of the entire store of water of the earth amounts to only 0.3%.

A larger problem than the quantity represents usually the water quality. By increased entry of nitrate, phosphates, plant protection agents and other chemical materials in the water the dressing becomes ever more difficult and more expensive. In addition, in some areas of Central Europe the water scarceness and being missing rains intensifies the situation additionally.

The rain water use can make a valuable contribution through saving of drinking water to deal with the raw material water more carefully.

Free rain water use

Rain water has the advantage that it is free, neither to be prepared nor over long distances transported must. For the following applications rain water is in the best way suitable and has even still positive side effects:

With WC-flushings the largest quantity can be saved, besides no urine stone forms.

Optimally for washing machine, whereby by the better Waschwirkung 50% detergents can be saved and calcifying the machine is prevented.

Well suitably for the Pflanzenwässerung, since the plants can take up so optimally minerals.

In addition the rain water use helps to reduce with strong downpours the discharge points in the duct system and offers the possibility of being able to dimension central retention basin smaller.

In combination with infiltration an ecologically optimal concept results, since the Rückhaltung is consistently supported here.

Worthwhile investment

„It is an investment, which is worthwhile itself, is pleased “an owner about its rain water use plant in its new home of one's own. When optimal planning in the new building the establishment costs are not a problem, because only the underground rain water cistern and the system control strike themselves really with the costs to beech explain the owner. Everything else is nearly only pipework system, which also a skillful do-it-yourself enthusiast can shift in the carcass.

The principle of the rain water use is completely simple: With rains the rain water falls on the roof area and over the gutters as well as gutter-pipes is derived. Afterwards by a prefilter the rain water is cleaned and runs without whirling up into the underground rain water cistern. This is simply a collector, which consists of plastic or monolithic concrete. The size results from the rain water need of the household and the local amount of precipitation. As meaningful measure for the size of the memory 20 - 25 or 30 - 50 litres per square meter of roof area are considered depending upon location, i.e. with 100 m2 roof area can possess the memory approx. 2,000 - 5,000 litres capacity. The cistern - can be set up also in the cellar - is ventilated and with an overflow provided. Thus with full memory an uncontrolled Wasseraustritt is prevented. During connection to waste water drains a trap must be inserted.
Thus also longer periods without rains with the rain water cistern are bridged. Even if in our widths of the rains for above average long time should be missing, then simply drinking water is refed over a single solenoid valve. One regulates over the automatic system control the so-called rain water management. To note it participates that drinking and rain water may not mix themselves absolutely.

The rain water is not nevertheless constantly enriched by the calmed down intake into the cistern in disorder whirled, which causes a fine filtering, but with fresh oxygen. Fine particles such as sediments (sand, etc.) are heavier than water and sink therefore to soil. Oils and fats swim on the water, why a swimming withdrawal is recommended 15 cm underneath the rain water surface. Thus in each case „the cleanest “rain water for Klospülung, laundry washing, cleaning and garden irrigation is taken and fed by means of a pump into the rain water power mains.

With the building of a rain water use plant the valid regulations and standards are to be kept absolutely.

„Ökohaus existing building “successfully uses a rain water use of GEP environmental technology GmbH for the WC-flushings, washing machines, house cleaning and the garden irrigation for more than three years. The rain water quality corresponds to the German drinking water regulation (TVO) for drinking water from own and single investments up to a withdrawal of 1000 m after a laboratory test of the hygiene parameters ³ per year.

“Ökohaus existing building “demonstrates impressively the high quality to ours
Rain water use plants, in particular the outstanding water quality " so Klaus Zotter, managing director of GEP Austria.

Ökohaus - existing building means a building

with the elements of nature:

Sun, water and earth

They mean the life and actually also ecological building. Get simply the cycles of nature with gentle technology in the house.

Ökohaus - existing building arranges from it a collective concept of the superlow-energy building up to the solar and rain water use.

Further energy-saving electrical appliances and energy energy-savings lamp are used.
