Tired of Flooded Streets? Stop the Damage Fast

A complete guide to choosing and using water butts in the UK – including smart systems and tips for installation.

🌧 What Are Water Butts?

Water butts UK are rainwater collection tanks designed to capture and store rainwater from your roof via downpipes. In a time of increasing water bills and unpredictable weather patterns, water butts provide an effective, eco-friendly solution for households, schools, and businesses.

A water butt helps reduce reliance on mains water, lowers flood risks, and contributes to sustainability efforts. Even better? Smart water butts take rainwater harvesting to the next level with automation and data-driven management.

💷 Why You Should Use Water Butts in the UK

✅ Reduce Your Water Bill

In metered households, using rainwater instead of mains water can cut outdoor water use by up to 50%, saving an average of £100–£150 per year. Waterwise reports that outdoor water use can account for up to 60% of summer water consumption.

✅ Help Prevent Flooding

Water butts reduce the volume of water entering sewers during storms, easing pressure on drainage systems and helping to prevent localised flooding — a major issue across the UK. Read more on CIRIA’s SuDS guidance.

✅ Better for Plants and the Planet

Collected rainwater is free from chlorine and water treatment chemicals, making it ideal for your garden. Even the RHSrecommends water butts as part of sustainable gardening.

📊 How Much Rainwater Can Water Butts Collect?

In the UK, the average roof collects around 85,000 litres of rainwater per year. A standard 200-litre water butt can fill in a few hours during heavy rain. Linking multiple water butts increases storage and helps manage rainfall more efficiently.

🧠 What Is a Smart Water Butt?

Unlike traditional models, smart water butts automatically release stored rainwater ahead of storms to prevent overflow and maximise collection capacity. Powered by IoT technology, these systems:

• Monitor water levels in real time

• Integrate with weather forecasts

• Support Sustainable Drainage Systems (SuDS)

• Connect via LoRaWAN for public sector scalability

The AQUAIOT Smart Water Butt is already helping local authorities and housing developments tackle flooding and water waste simultaneously.

🏡 Where Should You Install a Water Butt?

To make the most of your water butts UK, install them:

• Beneath a roof downpipe

• On a flat, solid surface

• Near garden areas or where water is needed

• Close to communal downpipes in shared buildings

Make sure it’s easy to access, shaded (to prevent algae), and tightly sealed.

📏 Choosing the Right Size Water Butt

Water butts come in a range of sizes, depending on your needs:

• Small gardens: 100–200 litres

• Average homes: 250–500 litres

• Larger or smart systems: 500–1,000 litres+

• Public or commercial sites: Multi-butt smart systems

See reliable suppliers like Water Butts Direct or The Green Age for options.

🛠️ Maintaining Your Water Butt

Keep your water butt clean and effective by:

• Cleaning your gutters and filters quarterly

• Flushing the tank once or twice a year

• Using rainwater treatment tablets if water is stored long term

• Keeping the lid closed to prevent debris and insects

The Environment Agency also recommends water butts as part of flood resilience measures.

🏛️ Council & Government Support in the UK

Many UK councils, like Thames Water and Yorkshire Water, have offered discounted water butts and rainwater harvesting grants to encourage greener homes.

Check with your local authority for incentives that may help offset the cost of your water butt.
