Many developers are turning to rainwater harvesting to solve high water usage in their buildings. Rainwater is plentiful, legal, and safe to reuse in the UK.
Organisations committed to sustainability recognise the numerous benefits of collecting rainwater from their roofs.
Explore some of the advantages below and ensure you don't miss out by including this valuable technology in your project.
The problem
Many of us take water for granted. By the time it reaches our taps and toilets, it has undergone extensive treatment and transportation. The reality is that our current water supplies are insufficient to meet future demand. This is due to climate change, population growth, and water misuse.
The advantages of rainwater harvesting
Collecting rainwater from roofs significantly reduces reliance on public water supplies. Rainwater harvesting provides a non-potable water source that can meet up to 75% of your total water demand.
Without rainwater collection, valuable rainwater would be lost to the drains instead of being reused as an alternative water supply. Rainwater lands clean and clear making it ideal for reuse as little filtration to make it safe for non-potable use.
The problem
As we continue to develop our built environment, there is less opportunity for stormwater to naturally infiltrate into the ground. Because of this, there are higher volumes of stormwater requiring artificial drainage via our sewer network.
Another problem is that many of our sewers are "combined." This means that wastewater from toilets is sent through the same pipes as stormwater. To prevent the system from flooding during heavy rain, combined sewers have an emergency overflow. This overflow releases untreated sewage into our natural water bodies to avoid flooding.
The advantages of rainwater harvesting
Installing a rainwater harvesting system significantly reduces the amount of rainwater runoff entering external drains by collecting and storing the rainwater on-site for reuse.
Many specifiers choose to connect their rainwater harvesting system to on-site attenuation capacity, creating one intelligent system via Active Attenuation. Combining these technologies has many benefits including, reduced installation requirements and increased flood resilience.
The problem
Because of excessive water extraction from local aquifers in the Arun Valley, Horsham has been designated as a water neutrality zone by Natural England. Water neutrality applies to new developments, ensuring that water usage on new developments does not exceed that of the original site use.
Water neutrality involves installing water-saving measures such as low-flow taps, aerated showers, and water reuse systems.
The advantages of rainwater harvesting
Rainwater harvesting is crucial for providing an alternative water supply in areas of water neutrality. As part of the design process, developers will be required to prove their compliance with water neutrality through saving estimates.
Stormsaver is on hand to provide you with water-saving estimates for your rainwater harvesting system.
The problem
The world’s resources are limited. That is why businesses have a part to play in improving their sustainability credentials to ensure long-term viability.
Many businesses tick the sustainability through carbon and energy reduction. Despite its importance, water is often treated as an afterthought. But can you imagine running your business without water?
The advantages of rainwater harvesting
Rainwater harvesting helps you to limit your business's reliance on precious drinking water supplies. If your staff and visitors are still flushing your toilets with mains water, this is a huge waste.
With trade water supply and effluent charges dramatically increasing, rainwater harvesting gives your business greater autonomy over where your water comes from and how much you pay for it.
The technology efficiently reduces water consumption all without the difficulty and expense of educating your building users to save water.
