plant, which desal<strong>in</strong>ates the water of the village well. The br<strong>in</strong>e which is produced<br />

as the by-product of the RO system is be<strong>in</strong>g used as the water source for the water<br />

pyramid system. At Shirva two tanks of 5,000 litres capacity have been constructed for<br />

collection of the distilled<br />

water, while the ra<strong>in</strong> water<br />

will be collected <strong>in</strong> a<br />

pond with the 4000 sq m.<br />

The sett<strong>in</strong>g up of this water<br />

pyramid was made possible<br />

by the partnership between<br />

WASMO, Aqua-Aero WaterSystems BV and the Government of the Netherlands <strong>in</strong><br />

cooperation with the VRTI (a local NGO partner implement<strong>in</strong>g WASMO’s dr<strong>in</strong>k<strong>in</strong>g water<br />

project <strong>in</strong> the village), the Gram Panchayat and Pani Samiti of Shirva village.<br />

Water cones<br />

While the water pyramid has obvious benefits the high <strong>in</strong>itial capital is a major limit<strong>in</strong>g<br />

factor. The search for simpler and cheaper applications of the solar still has led to the<br />

development of small, portable water cones. A typical water cone yields between 1.0 to<br />

1.7 liters of condensed water per day. These yields were reported for WATERCONE(r)<br />

with a base diameter of 60-80 cms tested <strong>in</strong> Casablanca, Morocco where the average<br />

evaporation level was 8.8 liters per sq m.<br />

The water cone is made from transparent, thermo-formable polycarbonate (same as<br />

water dispensers) outfitted with a screw cap spout at the tip and an <strong>in</strong>ward circular<br />

collect<strong>in</strong>g trough at the base. Salty / brackish water is poured<br />

<strong>in</strong>to the pan on which the water cone is floated. The black<br />

pan absorbs the sunlight and heats up the water to support<br />

evaporation. The condensed droplets trickle down the <strong>in</strong>ner<br />

.<br />

wall <strong>in</strong>to a circular trough at the <strong>in</strong>ner base of the cone. By<br />

unscrew<strong>in</strong>g the cap at the tip of the cone and turn<strong>in</strong>g the cone<br />

upside down, one can empty the potable water gathered <strong>in</strong> the trough directly <strong>in</strong>to a dr<strong>in</strong>k<strong>in</strong>g<br />

device. WATERCONE(r) is a long last<strong>in</strong>g UV-resistant poly carbonate product and can be<br />

used daily for up to five years. The material is non-toxic, non-flammable and 100 per cent<br />

recyclable.<br />
