What is Rainwater Harvesting? Methods, Benefits, and more

What is Rainwater Harvesting?

Rainwater harvesting is the process of collecting and storing rainwater that would otherwise flow into storm drains or be lost as runoff. This water is typically collected from rooftops and stored in tanks or other storage systems for later use. By implementing rainwater harvesting, individuals and businesses can reduce their reliance on traditional water sources, lower water bills, and contribute to environmental conservation.

At Fast Drains, we specialise in sustainable solutions, and rainwater harvesting is one of the many ways we help our clients optimise water usage while protecting the environment.

Types of Rainwater Harvesting Systems

1. Basic Rainwater System

The basic rainwater harvesting system includes simple setups like rain barrels or water butts. These systems are cost-effective and often have a capacity of up to 400 litres. They’re ideal for smaller properties and can be freestanding or paired with submersible water pumps for distribution.

Best for: Residential properties or gardens needing minimal water storage.

2. Aboveground Rainwater System

Aboveground systems feature larger tanks with capacities ranging from 800 litres to 100,000 litres, depending on their material and intended use. These systems are relatively easy to install and are suitable for commercial, industrial, or larger residential properties.

Best for: Properties with ample outdoor space and higher water usage needs.

3. Underground Rainwater System

For properties with limited outdoor space, underground rainwater harvesting systems offer a practical solution. These systems require excavation work and the installation of pumps to redistribute water from the storage tank to where it’s needed. While more expensive upfront, they provide long-term benefits and preserve aesthetic space.

Best for: Urban areas or properties where outdoor space is a premium.

Uses of Harvested Rainwater

Harvested rainwater has a variety of applications, including:

Outdoor Use: Watering gardens, washing vehicles, and cleaning patios.
Indoor Use: Flushing toilets and supplying washing machines.
Commercial Use: Landscaping irrigation, cooling systems, and more.

By using rainwater for these purposes, property owners can significantly reduce their reliance on municipal water supplies.
