- Stormwater
- Wastewater
Why Rainwater Capture Matters
Rainwater capture has lots of benefits for the environment, our ecosystems, communities and it helps to combat flood risk. Here are just a few reasons why it matters:
Capturing rainwater slows the flow into our drainage systems, helping to reduce pressure on wastewater treatment facilities and to reduce stormwater overflow discharge.
Sustainable rainwater capture systems such as planters, green roofs and rain gardens can provide a habitat and refuge for urban wildlife.
Managing rainwater effectively protects properties from damage caused by water infiltration, foundation weakening, and mould growth, particularly in flood-prone areas.
By harvesting rainwater for non-potable uses like irrigation, businesses and homeowners can reduce their dependence on plumbed water, thus reducing their bills if on a water metre.
Capturing rainwater reduces the amount of polluted runoff entering our water systems, which helps improve overall water quality. By intercepting rainwater before it flows across roads, roofs, and other surfaces, rainwater capture systems helps to reduce harmful contaminants like oil, heavy metals, and debris from reaching natural water bodies.

Rainwater Capture Devices for Small Spaces
- Slimline Wall Water Butts
- Rain Planters
- Underground Tanks with Surface Access Points
- Barrel-Style Water Butts
Fits tight corners or along walls. Storage capacity of these are limited however they take up little to no space in your garden.
Rainwater Capture Devices for Larger Spaces
- Freestanding Large Water Butts
- Rain Gardens
- Green Roofs
Large-capacity barrels designed for significant rainwater collection. These high capacity devices are perfect for large gardens or properties and are simple to connect to multiple downpipes. They do requires ample space for placement and aren't the most attractive option.
High-Capacity Devices for Gardening Enthusiasts
- Multi-Barrel Linkage Systems
- Open Water Features or Ponds with Catchment
Increases capacity by linking several separate barrels together. These can be purchased and connected together for this purpose or you can modify standard water butts to do this. This is perfect for storing a large amount of water and can be added to over time, however, they can take up significant space.
Techy and Smart Rainwater Collection Solutions
- Smart Water Monitors
- Automated Rainwater Irrigation Systems
- Solar-Powered Pump Systems
- Weather-Synced Watering Systems
These tracks water levels and usage through sensors which are often located on the lid of the water butt. These are usually installed by water companies or Lead Local Flood Authorities (LLFA's) to help with water management in a targeted areas. This helps them with rainfall data and informs decision making.
Cost-Effective Rainwater Collection Solutions
- DIY Water Butt Kits
- Repurposed Containers
Affordable and customisable for beginners. You can even add small pipe halfway up that will slowly 'leak' over time, making sure there's always capacity should it rain.

Conclusion
There is a vast array of products to choose from when it comes to rainwater capture devices. These vary in size, price, features and aesthetic. Therefore it would be prudent to choose the right rainwater capture device based on your needs and preferences. It would be wasteful to buy an expensive system should your needs be simple. Hopefully this guide will give you the information that will help you make that decision.
