Rainwater Harvesting

Rainwater Harvesting has many advantages, first being; its free, you can store as much as you want then reuse it how you want. Second is that rainwater is softer then tap water, which means that if you were to use rainwater in you washing machine lime scale would take longer to build up. If you were using the water for you garden, then some plants respond better to rainwater than tap water.

Climate change has and will continue to play a big part in our lives. The demand for water resources has rise, however the availablity of water has declined. Along with these problems, homes and businesses are across the UK are being fitted with water meters, which means water is now even more expensive.

We have a large range of systems which can be used for the garden or domestic use. We also have a selection of commercial rainwater harvesting systems which can be used in factories and warehouses.

Rainwater Collection FAQ's

Q: I have a high water table and feel an underground water would not be suitable for me, what should i do?

A: High water tables are not uncommon, installing an underground can be down, however this would mean you encasing the entire tank in concrete. Otherwise if you still feel unsure about an underground water tank then you could have a large water tank over ground or a number of water butts connected together.

Q: Can I install a rainwater harvesting system in a existing house?

A: Yes a rainwater harvesting system can be install at anytime, however if you are thinking of a new build you are better to install while at the footing stage of the build.

 

Water Butts

Rainwater collection is a fast up and coming trend for the garden. With water bills now too high, many of us are looking to collect as much water as possible and reuse it in our gardens and also for flushing the toilet.

We have many different styles and colours for you to choose from, from tall and slim water butts to long a narrow tanks. We have a tank for everyone, if you looking for an extra big rainwater tank then we even stock extra large tanks which reach 19,000 litres.

About Rainwater Harvesting and iRain

At iRain we specialise in rainwater collection and the uses after collecting the rainwater.  You can choose from our many underground rainwater harvesting tanks as well as the above ground rainwater tanks. These are available in multiple sizes from 280 litre to 7000 litres. The underground water tanks can be connected together to create greater volume.

Our rainwater harvesting systems are available for the home, garden and commercial use. You can install these systems in to existing buildings as well as new builds.  All the parts and fittings used in our rainwater harvesting systems are standard UK fittings available in most hardware stores.

All our rainwater tanks have BSP outlets which are perfect for adding a standard garden brass tap to.  Our BSP outlets are available from ¾” to 2” on selected water tanks. Other outlets can be added to the tanks after production however they be plastic tank connector instead of the brass BSP inserts used in the manufacturing process. They also have a vented screw down lid which is available from 4” to 16”.

All the rainwater harvesting system and rainwater tanks are made in the UK which gives us the advantage to offer a next day if required (depending on stock levels).  This also means in the unlikely event of a replacement tank/part be required, we can get one to you quicker than most.

The basic principles involved with our rainwater harvesting systems are as follows; The rainwater falls on to your roof and follows its natural path down the guttering and then normally straight down the drain. At the this point you divert the rainwater into one of our inline cylindrical filters this then flows out of the filter and into the underground water tank. From here it depends on what you want to use the rainwater for, as to what pumping system you would need. If you were using the rainwater for a domestic purpose such as flushing the toilet, then you would need a stainless steel booster pump kit.  The water pump would be installed in your house or a place where it can’t get damp, wet and protected from frost, this would then have a pipe running down to the water tank which would suck water up through the pump and send it to where it needs to go. Attached to the pump is a small pressure switch which would turn the pump on when the tap or outlet is opened, it would then turn the pump off when the tap or outlet is closed.

If you want the rainwater collected to be used in the garden your would need a different pumping system, however you can run both domestic and garden water systems off of the pumping system mentioned above. However if you only want to water the garden and not have any rainwater domestic supplies then there is a simpler system.  With the garden system you would have a submersible water pump installed in the underground water tank, this would then be connected to a pressure switch which you install into the provided pressure switch house (or you can install anywhere else providing it is protected from the elements). Connect a brass garden tap to the pressure switch via the flexi tap connector provided and wire the pressure switch to the pump via the mains and this will work in the same way as the domestic system.

When it comes to grey water it is a bit of a "grey area", 'what can i recycle?', 'is it safe'. Read our grey water page hopefully it will help

Why should we harvest rainwater?

We use 70% water today than we did 40 years

By reducing your water usage you can:

  • Save money on our water bills (especially if your on a water meter)

  • Reduce the damage which is done to wildlife in wetlands, reservoir and rivers.

Underground water tanks don't have to be sunk in ground;, they can be installed under patios or under decking as shown (right). All accessories such as water pumps, filters and fittings can still be installed.

One of the best things about Ecosure Rainwater Harvesting Tanks is that they can connect together give you a larger volume of water, then, just like a normal house hold system, the water can be recycled back into the header tank of the building then reused when someone flushes the toilet or turns on the tap.
