Lessons Learned About Rainwater

A Guide to Rainwater Conservation

Supplementing water used in the various setting through rainwater harvesting including agriculture, household and domestic use, commercial and industrial uses is important. Rooftop water harvesting is the commonest rainwater harvesting practice. Rainwater harvesting is important as it helps collect water for later use mostly when there is scarcity as well as enhancing one’s self-sufficiency. Rainwater harvesting for various uses has some implication in economics mostly when water generally used is charges and also environmental in enhancing conservation. Rainwater is usually collected from the rooftop using gutters into a given collection point.

Various types of materials are used in the making of rainwater tanks where the rainwater collected is usually stored. The various materials used in the making of the rainwater tanks includes plastic, concrete, fiberglass, aluminum metal, and stainless steel which should be resistant to rust and other chemical reaction. The type of material used in making the rainwater tank usually depends on the durability as well as the affordability of the materials. Plastics tanks are highly preferred to other types of tanks, but they are less durable as compared to concrete water tanks. Tanks used in rainwater harvesting are either placed on the ground surface or can be placed underground. Underground water tanks usually require that the water be pumped from the tanks since they cannot be fitted with a valve or a water tap.

Rainwater tanks should be covered at all times leaving just a small hole where the pipe discharging water can pass through so as to avoid unwanted materials from dropping into the water. Plastic rainwater tanks are more preferred since they are readily available and come in different sizes according to one’s specification. Algae growth is common when plastic tanks are placed on the ground hence should be placed on a surface that keeps away algae such as concrete. Plastics rainwater tanks have reduced durability when exposed to solar radiation hence should be placed where there is no direct solar. Other rainwater tanks made of other materials used should be well fitted to avoid contaminants getting into the water more so if the rainwater collected is for human consumption.

Harvested rainwater usually have a lot of contaminants hence should be sterilized for human consumption. This is because there are so many contaminants that settle on the rooftop and ones it rains they usually find themselves into the water. Chlorination and filtration are some of the ways of removing contaminants. The most used method in sterilizing water is chlorination since it is quite effective and also affordable. Loads of contaminants usually settle on the rooftop hence it is important to ensure that water is not harvested during the first rain so that the contaminants cannot find their way into the rainwater tank.
