Collecting Rainwater From Your Roof

Rainwater Harvesting

Rainwater harvesting is one of the most efficient methods for conserving water, with numerous advantages for both individuals and the environment. When done correctly, the procedure allows users to collect rainwater that falls on roofs, hard surfaces, gutters, and drains (that would otherwise be wasted) and store it for later use.

Rainwater harvesting systems come in a variety of shapes and sizes, but they are all relatively easy to set up and maintain, making them a popular choice for homeowners, farms, and commercial and industrial businesses.

What Is Rainwater Harvesting?

Simply put, rainwater harvesting is a process used for collecting and storing rainwater. It’s a very effective way to make the most of the rainfall and to ensure that less goes to waste.

Just think about the rainwater that falls on roofs, hardstand areas, paths and other impermeable surfaces. Usually, all this precious water would simply run into the stormwater system or the drain away, but rainwater harvesting allows it to be captured and used to supplement or replace reticulated water used in a wide range of applications – both indoor and outdoor. Remember in times of water restrictions, tank water is yours to use as you want.

  • A conveyance system consists of gutters and downpipes that direct rainwater from the collection surface to a rainwater tank.
  • Leaves and other debris are kept out of the storage tank by using diverters and filters.
  • A storage tank will be used to safely store the gathered water.
  • A distribution system consists of pumps and pipes that convey water from the tank to its final destination.

What Is The Purpose Of Rainwater Collecting?

Rainwater can be used for a variety of reasons, and it can be used to complement or even completely replace municipal water supplies.

Rainwater collected from roofs may be classified non-potable (depending on region) before it is treated in some places, however, there are still many uses for untreated rainwater, such as:

  • Non-potable indoor fixtures (toilets, washing machines, etc.)
  • Irrigation of lawns and gardens
  • Vehicles, pets, and outside locations should all be washed.
  • Fountains and ponds must be refilled.
  • Water for livestock to drink

The average Australian family uses between 250,000 and 300,000 litres of water per year, with more than half of it flushed down the toilet and used for landscape watering.

Using rainwater for these reasons would dramatically reduce the amount of water consumed and wasted by each household.

Rainwater can also be used for drinking and other potable purposes, as long as it is treated properly. Water treatment and filtration systems are inexpensive and allow you to use rainwater for a variety of purposes, including:

  • Showering and bathing
  • Dishes
  • Cooking Drinking

What Are Rainwater Harvesting’s Advantages?

Rainwater harvesting is appealing for a variety of reasons.

The following are some of the reasons:

  • Rainwater harvesting aids in the conservation of water that would otherwise be wasted.
  • It will help you save money on your water bills from the city and water providers.
  • It relieves the strain on the reticulated water supply.
  • Reduces stormwater system capacity limits.
  • In times of drought or water limitations, it provides a supplementary water supply.
  • Installing a rainwater collecting system will increase the value of your home.
  • Because rainwater is not chlorinated, it is helpful to plants and gardens.
  • Rainwater harvesting is a low-cost and simple-to-maintain technique.
