Rainwater harvesting is a cost effective and sustainable method of collecting rainwater. It is however crucial to ensure that the water is free from any kind of contamination before using it for drinking. There are several techniques like using chlorine tanks for the purpose.
Appropriate Storing of Rainwater
It is important to put in place correct methods of rainwater harvesting.
The roof catchments, which collect the rain as it falls, should be clear of leaves and other debris at all times. Remove any overhanging branches from trees nearby.
In addition, you can install a first-flush device to prevent the first shower of rain after a dry period from entering the tank. The system diverts the water together with the debris accumulated on the rooftop away from the rainwater tanks.
Use a wire mesh at the inlet and the overflow pipe to screen insects and small animals from getting into the tank. The wire mesh is vital to prevent the breeding of mosquitoes in the rainwater reservoir.
A leaf trap is essential to minimise the entry of leaves and other organic matter into the tank, as well.
Install a cover for the reservoir that allows no gap at the edges to prevent dust particles from entering. The material of the cover should restrict the outside heat from entering the tank because the heat may encourage algal bloom within the water and contribute to the multiplying of microorganisms in the water.
Install a tightly sealed manhole on the cover to allow entry for cleaning the tank.
