RainSmart by DrainX

 The average UK garden is around 190–200m², with South East properties often enjoying even larger spaces, averaging up to 333m². This makes rainwater collection especially valuable for homeowners looking to keep their gardens green while cutting water costs.
 

 A standard garden hose can use up to 1,000 litres of water per hour—around 12 full bathtubs—making even short watering sessions surprisingly costly. One minute of use can release over 15 litres, highlighting the benefits of smarter, more sustainable options like rainwater collection. 

 Watering an average UK garden with a hose for 30 minutes, three times a week, can use around 1,500 litres per week—or 6,000 litres per month. In hotter, drier months, that number can more than double, especially for lawns. This highlights the value of rainwater harvesting as a cost-effective, drought-resilient solution. 

 In the South East, metered households typically pay between £4 and £6.50 per 1,000 litres of water, covering both supply and sewerage. Even garden water use is charged this way, meaning regular hose use can quickly add up. With average rates around £5 per cubic meter, rainwater collection can significantly reduce your summer water bills. 

 Watering a typical garden three times a week in the South East can add £25–£40 per month to your water bill—around 6,000 litres of usage. That’s equivalent to an extra week’s bill just to keep your garden green. Larger gardens or hotter weather can push costs even higher. Installing a rainwater collection system like RainSmart is a smart way to cut costs, reduce reliance on mains water, and stay prepared for hosepipe bans.
