Rainwater harvesting tanks are a great way to collect and store rainwater for use around the home and garden. They are becoming increasingly popular in the UK, as people become more aware of water conservation and sustainability benefits.
Benefits of rainwater harvesting tanks
There are many benefits to using rainwater harvesting tanks, including:
- Reduced water bills: Rainwater can be used for various non-potable purposes, such as watering the garden, washing the car, and cleaning the patio. This can help to reduce your water bills significantly, especially during the summer months.
- Improved water quality: Rainwater is generally softer than tap water, benefiting your skin and hair. It is also free from chlorine and other chemicals that can be found in tap water.
- Reduced environmental impact: Rainwater harvesting helps to reduce the strain on municipal water supplies, which can be especially important during periods of drought. It also helps to reduce pollution, as rainwater runoff can carry harmful chemicals into waterways.
Types of rainwater harvesting tanks
Rainwater harvesting tanks are available in various shapes, sizes, and materials. The most common type of tank is made from plastic, which is durable, lightweight, and easy to install. Plastic tanks can be placed above ground or below ground, depending on your needs and preferences.
When choosing a rainwater harvesting tank, it is important to consider the following factors:
- Size: The size of the tank will depend on your needs and the amount of rainwater you expect to collect. For a typical household, a tank with a capacity of 1500-2000 litres is usually sufficient.
- Location: If you have limited space, you may want to choose an above-ground tank. However, below-ground tanks are less visible and can be better insulated.
Installing a rainwater harvesting tank
The installation process for a rainwater harvesting tank will vary depending on the type of water tank and the location where it is being installed. However, some general steps are involved, including:
- Choosing a suitable location for the tank.
- Preparing the site for the tank. This may involve levelling the ground or digging a hole for an underground tank.
- Connecting the tank to your guttering downspipe.
- Installing a filter to remove debris from the rainwater.
- Installing a pump to distribute the rainwater to your desired locations.
Maintaining a rainwater harvesting tank
Once your rainwater harvesting tank is installed, it is important to maintain it properly to ensure safe water quality. This involves:
Cleaning the tank filter regularly to remove debris and algae.
Inspecting the tank for any leaks or damage.
Testing the water quality regularly, especially if you use it for drinking or cooking. (with the use of additional UV filters)
