Storage tanks are the simplest method for rain water harvesting. It basically involves putting to use that water from roof tops that would either be evaporated or soaked by the ground. Roofs in our homes therefore become the best catchment areas that feed into rainwater tranks. It is a technique of collecting, filtering, storing and use of rainwater for different purposes among them irrigation. Below are merits of rainwater harvesting.  

Easy maintenance

Drinking water is not easily renewable and therefore harvesting the rain water allows you to better utilize an energy resource. Simple technology is used for the systems of collection of the rainwater. Installation and operation cost in general therefore is much lesser than that of purifying. Apart from that, maintenance requires little time and energy making the process very efficient as the water collected can be used for different purposes without purification.  

Reduction of water bills

Water collected in this system goes a long way to help in reduction of water bills. This is because it can be used for various non-drinking functions too. Harvesting rainwater on an industrial scale provides needed amounts of water without necessarily having to deplete nearby water sources.  

Suitable for irrigation

Most rooftops serve the purpose of catchment areas therefore there is little probably not any requirement for new infrastructure building to harvest water. This in turn reduces use of fuel based machines in the environment. This water in question is free from chemicals found in ground water and therefore making it suitable for watering of gardens and irrigation.  

Reduction of floods and soil erosion

Rainwater during rainy seasons is collected in large storage tanks which assist in reducing flood in areas that lie low. Along with that, harvesting of rainwater also helps in reducing soil erosion and contamination of water surfaces with chemicals like pesticides and fertilizers from water run-off resulting to cleaner water sources like lakes and ponds.  

Can be used for several non-drinking purposes

Collected rain water can be used for several domestic non-drinking purposes. Some of these uses include doing laundry, flushing toilets, watering gardens and washing cars.  

Reduction of demand on ground water

Ground water is basically water that has not been harvested. That which already exists for example water from ponds and lakes. As population increases, demand for water also goes up and therefore this leads to depletion of ground water but thanks to harvesting of water, this problem can be contained.

The idea behind water harvesting process is quite simple. Rainwater is collected upon falling on the earth, stored and used at a later point. This water can be can be purified for drinking purposes, daily domestic applications and even in large scale industries.
