How to collect rainwater properly to use later in your garden

I stayed in Palau for a few months, in the Pacific, where water was the main source of fresh water. Defective pipes served the town but only on the coral isles. Each safe house gathered water from the covered or metal rooftop and put away it in a sparkly steel tank with a mesh filter on top.

After you check local laws, consider your objectives. The idea is to make a dependable, safe, and effective water collection system for your own use, with modest materials utilizing essential construction skills.


With water, vitality, nourishment, and different commodities, it’s less expensive to conserve waste than to make another source. Drip irrigation is a decent water-conservation venture, as in low-flow toilet or flow control for a tap or shower. In the event that water is a difficult issue in your location, don’t waste it flushing toilets.

Why Rain Water?

Rain offers the cleanest natural water accessible, made by nature’s evaporative refining process. Just airborne residue particles and man-influenced contamination to can taint it. Where the air conveys smoke and ash or airborne contaminations from industrial processes including fossil fuel, rain isn’t perfect.

The Downside of Rainwater

How about we take a gander at a portion of the disadvantages of rainwater harvesting:

Supplies can be tainted by animal and bird droppings on the catchment surfaces and guttering structures except they are flushed or cleaned before use.

Inadequately built water tanks or holders can experience the ill effects of spillage, algal development, and intrusion by bugs, reptiles, and rodents. They can go about as a reproducing ground for illness vectors if they are not appropriately maintained. The greater part of that infers a high-level responsibility for proper maintenance

How Much Water can be Collected?

The run-off from a rooftop is specifically proportional to rainfall and the horizontal area of the roof. For each millimeter of rain, a square meter will yield one liter of water after calculation.

Hope to have the capacity to catch just 80% of whatever hit the rooftop after the rest is lost from overflow, leakage, evaporation, wind, spillage and splashing. Build down-pipes and guttering big enough to sufficiently catch crest volume run-off during extreme storms.

What is the Best Kind of Rainwater Storage Tank?

Storage arrangements, for example, rain barrels are usually 90% of the entire system cost. It can go from little holders made for different purposes—oil drums, food jars, and so forth. — up to expansive tanks at ground level, or sometimes underneath it. Huge tanks of cement or ferro-concrete are utilized as storage for clinics, schools or places with large areas of roof.

In a few locations in Africa, an organization called Water Aid is instructing folks on better approaches to create huge town or neighborhood storage tanks of local materials or a blend of concrete and sand, fortified with wood or fencing wire.

Consider your requirements and evaluate your choices. If you require cheaper, better or more water, then you should harvest the rain and store it for use during the dry periods.
