RAINWATER HARVESTING

WHY INSTALL A RAINWATER HARVESTING SYSTEM?

By collecting and using rainwater, you can reduce your reliance on the mains water supply and potentially lower your water consumption by up to 40%. This not only helps to ease the burden on the conventional water supply but can also lead to significant cost savings on your metered water bills.

WHAT DOES IT DO?

Rainwater harvesting is a sustainable solution that allows you to collect and store rainwater for later use, rather than letting it run off. This process involves collecting rainwater from the roof and directing it via gravity-fed pipework into a buried storage tank. The stored water can be used for various purposes, such as gardening, irrigation, and car washing. If you prefer to use the water for household purposes such as laundry and toilet flushing, the water can be filtered and pumped to a header tank located in the roof cavity.

HOW DOES IT WORK?

To harvest rainwater, the most common practice is to collect water from the roof, as it typically has fewer contaminants than other surfaces. This is done by utilising the existing guttering and downpipes to redirect the water to a storage tank.

The stored water can then be pumped directly to points of use, or directed to a secondary header tank in the loft for gravity-fed supply.

WHAT NEXT?

Harvested rainwater may not be of sufficient quality for drinking and cooking, but it can still serve as a valuable resource for tasks like laundry and toilet flushing. By utilising rainwater for these purposes, households can potentially reduce their reliance on mains water by up to 40%.

1 WE WILL COME OUT DISCUSS THE OPTIONS

The first step is deciding whether you want to use the harvested water in the home, in the garden or both. Domestic rainwater harvesting systems offers ultra fine filtration giving you the best quality water for use in and around your home.

Garden systems on the other hand enable you to maintain your garden year even during round even during periods of shortage and hosepipe bans

2 WE WILL DESIGN THE SYSTEM

Rainwater harvesting is a pretty simple system. There are however a few factors that need considering:

The amount of rainfall your get in your area
The space available for an underground tank
The space and load bearing capacity for a raised tank
The area and type of roof space used for collection

3 INSTALLATION

Installing a rainwater harvesting system in your garden is a straightforward process that can be completed in a single day. The process involves digging a hole for a large tank, creating a sturdy base with gravel, placing the tank in the hole, connecting it to your existing pipework, and adding filtration components and a pump. Once complete, the tank can be filled with rainwater and the hole backfilled with more gravel.

To avoid any potential contamination of your drinking water supply, it is necessary to install a separate plumbing circuit for rainwater harvesting systems used for flushing toilets and operating the washing machine. This dedicated circuit ensures that rainwater is only used for non-potable purposes within your home.
