A Guide to Rainwater Conservation

Rainwater harvesting is very important in all aspects of water use including in the agriculture sector, domestic water use as well as commercial and industrial water use. The mainly practiced rainwater harvesting is the rooftop water collection for various uses where water is collected in tanks. The major rainwater harvesting benefit is provision of water for later use when there is water scarcity or contaminated water and helps individuals enhance their water self-sufficiency. Economic enhancement, as well as environmental conservation, is greatly enhance by rainwater harvesting. 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. Durability and affordability are some of the major factors that have an influence on the choice of a rainwater tank to be used. Plastics tanks are highly preferred to other types of tanks, but they are less durable as compared to concrete water tanks. Underground placement or aboveground placement are two major ways in which rainwater tanks are set to collect and store water. 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. Rainwater tanks made from other materials can contain contaminated water unfit for human use hence safety measures should be put in place when using them.

Rainwater collected from rooftops for human consumption should always be sterilized through various means. This is because there are so many contaminants that settle on the rooftop and ones it rains they usually find themselves into the water. Contaminants can be removed through chlorination or filtration of the harvested rainwater. Preferred method is usually chlorination since it is affordable and also effective in water sterilization. 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.
