A Simple Guide To Rain Catchment At Home

More and more regions around the world are suffering from water shortages. It’s believed that due to the changing climate of the planet combined with the constant draw on fresh water by most large industries, potable water will not always be as abundant as it is now.

This isn’t to say that water will simply disappear, but rather that it will be increasingly difficult for officials to provide enough water for most people.

One of the best ways to circumvent this eventuality is by focusing on rain catchment, which is a popular method for those living off-grid lifestyles to always ensure there’s enough fresh water around. While there are plenty of areas around the world where rain doesn’t occur on a frequent basis, most people will find that they live in a place where there is enough rain to keep their storage tanks topped up for most of the year. Use these tips to create a working rain catchment system at home.


The very first step to take is to make sure that all the water caught by the actual catchment system has a place to end up. Long-term water storage is fairly easy, as long as the storage tanks in question are properly sealed from animal life, and that the water inside never sits still for too long. Storage tanks come in a wide range of shapes and sizes, but most normal households will want around 20000 litres of storage available, which should cover daily water usage.

Water tanks are not extremely cheap, but they’re a long-term investment that means the household will always have access to potable water, even if the municipal taps are no longer supplying, giving homeowners something to spend their winnings from Canadian Casino Online games on. It’s also worth investing in tank filters to catch any debris that might come through when the water is flowing out.

Roof Catchment

The easiest way to capture rain is by funnelling it down from the roof and into capture trays along the skirting. Where most modern houses will have methods of keeping water from accumulating on the roof and causing leakage issues, it’s possible to modify this system so that the water is instead moved into storage rather than down into a storm drain.

Gutter Protection

With the proper rain catchment gutter in place, it’s important to make sure that no large debris is able to enter the stream of water flowing down into the tanks. Here, large, gutter protection filters will come in handy, and can be purchased online or from most home depot stores.

It’s important to take the time to measure the length and width of the gutter so that the filter works properly – the last thing a homeowner wants is for a rat or other creature to become stuck at some point under the filter and cause the water to turn bad. Another option to consider is a rain head, which is a secondary filter that sits on top of the main pipe leading down into the rain tank below. This should filter out almost all smaller particles that the larger filter wasn’t able to catch.
