Downpipe Water Diverter – The Ultimate Guideline to Save Rainwater

Downpipe Water Diverter

A downpipe water diverter is a device that redirects rainwater from a downpipe into a collection tank or other storage system, rather than allowing it to flow into the ground.

When it comes to managing rainwater on your property, a downpipe diverters can be a valuable tool. A downpipe diverter is a simple device that diverts rainwater from your gutter system into a collection barrel or other storage system. This can help you conserve water and reduce runoff, all while providing a sustainable source of water for your garden or other outdoor uses.

How Downpipe Diverters Work

Downpipe diverters work by diverting water that flows down your gutter system away from the traditional drainage route and into a collection barrel. The diverter is typically installed in your gutter system, where it will sit at an angle to the downpipe. As water flows down the downpipe, it will hit the diverter, which will then redirect it to your collection barrel.

There are several different types of downpipe diverters available on the market, but most work in a similar way. Some diverters are automatic, meaning that they will automatically switch to the collection barrel when it’s full. Others require manual switching, which can be done by turning a valve or lever.

Benefits of downpipe diverter

There are many benefits to using a downpipe diverter, including:

  1. Water conservation: By diverting rainwater into a collection barrel, you can use it for watering your garden or other outdoor uses, reducing your reliance on municipal water supplies.
  2. Reduced runoff: When rainwater is allowed to flow into traditional drainage systems, it can cause erosion and carry pollutants into nearby streams and rivers. By diverting rainwater into a collection barrel, you can reduce runoff and help protect local waterways.
  3. Cost savings: By using collected rainwater for outdoor uses, you can reduce your water bill and save money in the long run.
  4. Sustainability: Using a downpipe diverter is a sustainable way to manage rainwater on your property, reducing your environmental impact and contributing to a more sustainable future.

Installation and Maintenance

Installing a downpipe diverter is a relatively simple process, but it’s important to follow the manufacturer’s instructions carefully. If you’re not comfortable doing the installation yourself, it’s best to hire a professional.

Once your downpipe diverters are installed, it’s important to maintain it properly to ensure that it continues to function effectively. This may include periodically cleaning out the collection barrel, checking for leaks, and ensuring that the diverter is properly aligned with the downpipe.

Why we need a downpipe diverters?

Here are some reasons why you might need a downpipe diverters:

  1. Water conservation: By collecting rainwater in a rain barrel, you can use it for watering your garden, washing your car, or other non-potable uses. This can help reduce your water bill and conserve this precious resource.
  2. Environmental benefits: When rainwater flows onto the ground, it can pick up pollutants and contaminants, which can eventually end up in our rivers and streams. By diverting rainwater to a rain barrel, you can help reduce the amount of pollution that enters our waterways.
  3. Erosion control: If you have a slope or hill on your property, rainwater can cause erosion by washing away soil. By diverting rainwater to a rain barrel, you can help reduce erosion and protect your landscaping.
  4. Flood prevention: If you live in an area with heavy rainfall, a downpipe diverter can help prevent flooding by redirecting excess water away from your home’s foundation.

Drawbacks of downpipe diverters

While downpipe diverters can be an effective way to conserve water and reduce stormwater runoff, there are some drawbacks to consider:


Downpipe diverters require regular maintenance to ensure they are functioning properly. If not maintained, they can become clogged with debris, which can cause water to overflow and damage the surrounding area.

Limited capacity:

The amount of water that can be collected using a downpipe diverter is limited by the size of the diverter and the capacity of the collection tank. This means that during heavy rain events, the diverter may not be able to capture all of the water, and some of it may still flow into the ground.


Installing a downpipe diverter can be complicated, especially if it needs to be integrated into an existing downpipe system. This may require the help of a professional plumber or installer.


The cost of a downpipe diverter and associated collection system can be high, especially if it needs to be custom-designed for a specific building or site.


Some people may not like the appearance of a downpipe diverter on their building, which could impact the overall aesthetic of the property.

Overall, while downpipe diverters can be a useful tool for conserving water and reducing storm water runoff, they do come with some drawbacks that should be considered before installation.


Overall, a downpipe diverter can be a valuable tool for managing rainwater on your property. By diverting rainwater into a collection barrel, you can conserve water, reduce runoff, save money, and contribute to a more sustainable future. If you’re interested in using a downpipe diverter, be sure to do your research and choose a model that’s right for your needs and budget.
