In January 2013, Stormsaver – the UK’s market leader in rainwater harvesting systems – celebrated its 10th birthday.
Commenting on the milestone, Stormsaver Sales Director, Lisa Farnsworth, said:
“We are very proud to be celebrating our 10th birthday. There are so many interesting and amazing facts about rainwater harvesting I could write a book! Here’s to the next 10 years.”
To mark the celebrations, Stormsaver has shared its Top Ten interesting facts about rainwater harvesting with Premier Construction.
Fact 1: Only 50% of water used in our homes needs to be of drinking quality.
Studies have shown that typical households flush 35% of their water straight down the toilet with a further 15% being used for washing clothes. This means that only 50% of a households’ water needs to be fit for human consumption.
Fact 2: Systems can help the country manage stormwater and flooding.
Rainwater harvesting systems work by collecting rainwater from the roofs of homes and buildings. By capturing and recycling rainwater, this helps us to manage excessive rainfall. Over time, this helps us to manage the likelihood of flooding and reduces any potential strain on local eco-systems.
Fact 3: How many times a day does your office flush a toilet?
The average commercial building in the UK with a 1500m² roof area could have collected 1.75 million litres of rainwater from their roof in 2011. If this was recycled using a Stormsaver system this could have meant up to 439,875 flushes of the toilet for free (based on a low flush of 4 litres).
Fact 4: There is gold at the end of the rainbow!
In summer 2012 the UK received over 366mm of rain during the 3 months from June to August. For the average 3-bed domestic property, this level of yield translates to 20,000 litres of rainwater. 20,000 litres of water would be enough for 5,000 toilet flushes or 400 loads of washing. Some of our clients have reported that since having a system installed their water bill has reduced by up to 50%.
Fact 5: Recycling rainwater can help the environment.
By collecting and using rainwater this reduces the demand for mains water. In turn, this helps to reduce carbon emissions, alleviates the need for new reservoirs and is kinder to the environment.
Fact 6: 85% of water used in businesses does not need to be of drinking standard.
As businesses use water in different ways to residential users, this means that only 15% needs to be fit for human consumption.
Fact 7: Recycled rainwater can help prevent the build-up of limescale.
When rainwater is recycled it is classified as soft rainwater. This type of rainwater contains no calcium deposits, which can affect the build-up of limescale on appliances and pipework. It is also much kinder to plants and crops as opposed to using mains water that has been chemically treated.
Fact 8: Some harvesting systems can be solar powered.
The Stormsaver Eco domestic system uses 75% less energy than traditionally pumped systems. This system can also be powered by a small solar panel, which will help users to save even more energy and costs than traditional systems.
Fact 9: Play your part in saving 750 cu.m. of treated mains water every year.
If half of the 60 million people living in the UK had a rainwater harvesting system installed, this could reduce the reliance on mains water by a staggering 750 cu.m. every year. This is a huge amount of water that could be saved.
Fact 10: The average person uses 150 litres of water every day.
Studies have shown that on average each person uses 150 litres of water every day through toilet flushing, washing machines, showers and baths. This figure could be reduced by half with the installation of a rainwater harvesting system. Over a year, this would help us individually to save and recycle 27,375 litres of water.
