Rainwater Harvesting Tanks

RAINWATER HARVESTING TANKS INFORMATION

Rainwater harvesting tanks and kits enable you to collect free rainwater and can therefore offer you huge economic and environmental benefits. Not only that, but because rainwater is completely natural it’s often a better alternative to tap water, which is treated. Rainwater contains minerals and microorganisms which help promote plant growth, it also provides naturally softer water which reduces the need for detergents when washing. The water cycle process naturally filters water and with additional filtration to remove remaining contaminants, it can be safely used for drinking and cooking.

While it’s hard to believe that water scarcity could be a problem in the UK, earlier this year it was listed as one of the largest global risks over the next decade according to the World Economic Forum. Rainwater harvesting tanks make use of a free resource by storing and filtering water that falls on roofs. Our rainwater tanks offer high-quality bulk storage in domestic, commercial and agricultural sizes. Capacities range from 1,350 to 20,000 litres.

RAINWATER HARVESTING EQUIPMENT

As well as manufacturing high quality water tanks, we also supply rainwater collection kits for domestic, agricultural and commercial water tanks. Our filtration and pumping kits are suitable for various roof and tank sizes and can be purchased together or separately.

Our equipment includes:

Rainwater filter diverter

Filters water from the guttering to remove dirt and debris before the water is diverted to the storage tank.

Calmed inlet

The calmed inlet oxygenates the existing water and prevents it from stagnating by releasing the water at the bottom of the tank.

Overflow siphon

When the tank reaches maximum capacity the overflow siphon diverts the excess water to drainage. It also removes pollen from the water surface to keep it clean.

Submersible pump

A manual or automatic submersible pump directs the water from the bottom of the tank to the desired output such as a hose or washing machine.

WHAT CAN RAINWATER BE USED FOR?

We’re big advocates of rainwater harvesting. Water is an ever more precious (and sometimes expensive) resource, so collecting it when the weather takes a turn for the worse can leave you with a store of water to do with as you wish. The most common uses of collected rainwater that we come across are:

•         Cooking and consumption: As it falls, rainwater is relatively clean, although it can become contaminated once it lands on the Earth’s surface. There are options for filtering out any contaminates, and once this is done the water is safe to use for both cooking and drinking.

•         Domestic appliances: It will come as no surprise that the majority of our water usage comes from flushing toilets, showering, using a washing machine or dishwasher, and so on. Using harvested rainwater for all of this instead can significantly reduce water bills.

•         Watering gardens and plants: Even in the British Summer, parts of the country can suffer a drought so for keen gardeners it makes sense to keep a store of water on hand to keep their plants and gardens well watered.

HOW TO HARVEST RAINWATER

Rainwater collection works by capturing water that falls on your roof. This water is then directed to a central point via normal guttering and downpipes to a storage tank, where it can be filtered on entry. You can read our blog How to Harvest Rainwater in Three Steps for more information.

WHAT SIZE WATER TANK DO I NEED?

We recommend buying the maximum capacity tank you can to reduce the chance of running out of water and to minimise the frequency of tank refills (or waste collection).

As a guide, we recommend the following capacities:

HOW MUCH RAINWATER CAN I HARVEST?

To calculate the volume of rainwater you can collect use the following formulae: 1” of rain x 1 square meter = 25 litres

The average annual rainfall in the UK is 44 inches. Check out the table below to see what your roof could yield with the average yearly rain:

GUARANTEE

All of our tanks come with a 10 year guarantee when registered, a 1 guarantee on ancillary goods, and a 3 month warranty on hoses.

DELIVERY

Tuffa Tanks are generally built to order. We can arrange delivery direct to site in the UK or abroad. Alternatively, tanks can be collected from our Uttoxeter factory.

Typical build times are as follows:

RAINWATER STORAGE TANK DESIGN

Our plastic rainwater tanks are made from recyclable polyethylene and are manufactured to ensure a maximum wall thickness at the base – where it’s needed most. They are also corrosion resistant, weatherproof and UV stabilised. They are also very durable and require little or no maintenance.
