How Rainwater Harvesting Plant Is Installed In The House?

With demand of water ever increasing due to limited availability of drinking water on the earth, various methods of conserving water is being adopted. One of these is rainwater harvesting. It is the process of collecting and storing rainwater into natural reservoirs or tanks, or subsurface aquifers before it is lost as a surface runoff. The most commonly used design of rain water harvesting in households is rooftop rainwater harvesting plant. Let’s take a look at how rooftop rainwater harvesting is installed-
• Call an expert plumber who has a wide knowledge and experience of installing rainwater harvesting plant in the households. First of all, your plumber would choose an appropriate place to install rainwater harvester. The best place for this is an area adjacent to the downspout (roof drain pipe) where most of the water from your roof is diverted. This is because the water will easily flow in direction of natural slope made on the roof and go down to the tank and fill it up.

• The roof would thereafter be cleaned of all the dirt, debris and dry leaves that may have gathered there overtime.
• Next, the PVC gutters are fixed to the walls with clamps to allow the water to go in the direction of the storage tank. The PVC gutters are to be fitted with end caps at the point where rainwater begins to flow in the direction of the tank.

• Next a rain separator or a washout pipe. This valve will close the flow of water to rainwater gutter when the roof is to be cleaned or when rainwater is not to be collected.

• For roofs that are surrounded with trees, the roof gets strewn with dry leaves. These leaves along with small twigs and other materials find their way into the rainwater gutter and block it. Therefore a leaf-trap is installed in the vertical down pipe.

• A filter is also installed on the top of the storage tank to prevent dust, leaves, and other organic matter from entering the storage. This will keep the rainwater clean.
• The storage tank is placed on a on a platform above the ground. It is painted in white color to keep the water inside cool. Cover the tank opening with concrete slabs or any local stone.

• An overflow pipes is installed on top of the tank which allow the excess rainwater to be safely disposed from the tank. The overflow pipe should have a mesh at the bottom to prevent entry of small animals or insects.

• A hand pump is installed on the storage tank to draw the rainwater out day-today use.
