  2. 2. Rainwater harvesting can be a great alternative water source that’s both practical and eco-friendly. Although it is more common in rural areas, harvesting rainwater is also feasible in urban areas. It reduces dependence on and demand for public water supply and trims water bills as well. Here are common methods used to make rainwater safe for drinking and household use. Sanitising and Filtering There are several factors that affect the quality of rainwater. Rainwater alone is not potable, but through various treatment techniques, it can be as safe to drink as tap or distilled water. Roof and other catchment structures may affect the quality of rainwater, so the entire roof structure must work together to maintain the efficient flow of rainwater.
  3. 3. The preliminary step to treating rainwater is making sure gutters, roof catchments and tank screens are free of leaves, branches, and other debris. Screens will keep foreign matter out of the incoming water and prevent the tank from being a mosquito breeding site. The next step is to shock sanitise the collected rainwater by adding liquid bleach or granular calcium hypochlorite. Homeowners may also opt for a commercial roof washer valve, a device sized to collect at least 30 litres of water for every 100 square metres of catchment area. This device makes the flow and treatment more efficient and accurate. Treating and Neutralising Treating rainwater can be a combination of several devices and processes to allow rainwater to reach potable quality. Most homeowners use ultra violet sterilisers to neutralise collected rainwater and then add solid pellet or liquid bleach chlorine feeders to administer chlorination.

There are several ozone treatment technologies that homeowners can choose from. Ozone treatment is a more versatile option, with varieties that can be tailored to various indoor and outdoor water applications. With quite a number of sophisticated technologies available today, from rainwater collecting down to purifying devices, rainwater can definitely be safe to drink. Bringing rain indoors could save the expense and environmental costs of treating and transporting household water.
