Claim 0:
1. An indirect evaporative cooling system for cooling a space adjacent to or containing an ablution bay, comprising:
the ablution bay comprising:
a plurality of water taps; and
a greywater drainage below the plurality of water taps;

a greywater storage tank having first and second sides; and
an evaporative cooler apparatus;
wherein the ablution bay is adjacent to or contained in the space to be cooled;
the greywater storage tank is fluidly connected to the greywater drainage system of the ablution bay through a piping network at least partially below the ablution bay and/or the space to be cooled;
the greywater storage tank is fluidly connected via an outlet to a water pump on the first side of the greywater storage tank, the outlet being positioned at a mid-height of the greywater storage tank, and the greywater storage tank is fluidly connected to the greywater drainage system of the ablution bay on the second side;
wherein the greywater storage tank comprises a plurality of heat pipes connected on one end perpendicularly to a wall of the greywater storage tank extending outwards; and
the plurality of heat pipes are equally spaced around the wall of the greywater storage tank;
wherein the water pump is fluidly connected to a top of an evaporative cooler apparatus and the evaporative cooler apparatus is located above the space to be cooled in a dome shaped housing;
wherein the evaporative cooler apparatus comprises;
a wet channel;
at least one spray nozzle; and
a dry channel;
wherein the at least one spray nozzle is located at the top of the evaporative cooler apparatus and is fluidly connected to the water pump;
wherein the at least one spray nozzle is connected to the wet channel;
the wet channel is located directly above the dry channel;
a first side of the dry channel is connected to a first opening with a fan and outside air;
a first side of the wet channel is connected to a first opening to outside air;
wherein the first openings of the wet and dry channels are located on a back side of the dome shaped housing facing the opposite direction of an entrance to the space to be cooled.
