Water wise with rainwater harvesting

By harvesting and utilising rainwater at home, not only are you saving on water prices and demand for municipal water supply, but we are also being water wise. The demand for clean and safe water by the public is placing pressure on municipalities, and as a result, prices soar. The latest trend in the green wave is installing a rainwater tank into your garden.

Urban Rain Systems

As Urban Rain Systems outlines, the loss of water to the home can become a serious problem. One cannot really function without running water — cooking, cleaning of the house and those who live in it, as well as flushing the toilets, become major issues. However, if you have a rainwater harvesting system in place, you reduce your dependence on other services. As a result, in the event of a lack of water, you have a safe and clean source on tap.

Benefits of rainwater harvesting

According to Water Rhapsody, benefits of rainwater harvesting systems are numerous, and include:

  • Environmentally sound
  • Reduces municipal water demand
  • Reduces sewage outfall
  • Reduces the capital needed for expensive dam building
  • Stored water is available during future water outages
  • adequate water for irrigation
  • Very cost effective
  • Storm water from roofs to street is almost eliminated
  • Reduces the need to top up swimming pools
  • Systems are very easy to maintain.
  • Exempt from all forms of water restrictions
  • Improves the quality of your lifestyle.

Rainwater Harvesting Installation

In addition to these benefits, installing a rainwater harvesting system is simple. Wetec summarises it in 12 easy steps:

  • Check that the roof surface is suitable for collecting rainwater
  • Install gutter mesh to prevent leaves and debris from blocking gutters
  • Fit gutter outlets from the underside of the gutter to prevent obstruction of water flow
  • Fit rain heads to downpipes to prevent blocking — these deflect leaves and debris as well as keeping mosquitos out of the pipes that hold water
  • Install water diverters to prevent the first flush of most contaminated rainwater from entering the tank
  • Ensure the tank screen is installed at the tank entry point to filter water and keep pests out
  • Select a water tank while keeping in mind annual rainfall, roof catchment area and water usage when determining size
  • Attach insect-proof screens or flap valves to the ends of pipes to keep the tank screen and tank overflow outlets to keep pests out and ensure the tank is properly vented
  • Use a tank top up system to automatically top up the tank with water in the event that they fall to a minimum level
  • Choose a pump system to distribute water inside and outside the home
  • Fit a purpose-designed rainwater filter after the pump to help reduce residual sediment, colour and odour
  • Install a level indicator to help monitor your water usage.

Be water wise with rainwater harvesting systems and ensure that you don’t go dry during the drought seasons.
