What can I use rainwater for?

Rainwater can be used for all outdoor uses; watering the garden, washing cars, cleaning down patios, driveways, walls etc, and ornamental ponds. It can also be used inside the house to flush toilets and feed washing machines. Rainwater use means less build-up of calcium deposits in appliances.

Rainwater is not suitable for drinking or for use in showers and baths. Rainwater is generally free of harmful minerals and in most cases chemicals but can be adversely effected by air pollutants and/0r contamination by animals in the catchment area. The only way rainwater can be used for drinking water is if it is treated by ultra-violet filters which are not practical in domestic use as generally a rainwater tank will not store enough water for total consumption in a domestic situation.

What size rainwater harvesting tanks do I need?

The size of a rainwater holding tank must match the demand for water with it’s availability as closely as possible.

BS 8515:2009 provides an authoritative and industry-approved means of calculating the optimum size of tank for household water use.

Unlike other industries it is better to reduce the size of the tank rather than over size it if in doubt as to the requirement. This is due to the benefit of allowing the tank to overflow at least twice a year to flush out floating debris. The tank chosen must therefore be a balance between rainwater supply and water demand.

In order to correctly size the tank, the capacity should be the lesser of either the rainwater supply or the water demand. A worked example demonstrating this principle is shown below:-

What’s a potable water tank?

Water tanks can be classified as ‘potable’ and ‘non potable’. If you are storing clean water for human consumption, whether it be for drinking, prepping food or cleaning dishes etc, then a potable water tank is what you are after. All potable tanks must conform to the WRAS (Water Regulations Advisory Scheme) so that the liquid is safe for human consumption.

Non-potable tanks are for the safe storage of non-drinking water or for ‘not suitable’ for human consumption, in many different environments and applications. Non-potable tanks can be used in applications like rainwater harvesting, irrigation, agriculture & horticulture and commercial purposes where mains water is not available.

The difference in classification between the two comes from the materials used during the manufacturing process, specifically the type of plastic used to line the inside of the tank which comes into contact with the contained water. Non potable tanks are more porous, making it easier for the bacteria to grow and can sometimes let off gases which can contaminate the water. The WRAS approved material lines the inside of the tank, making the tank fit for human consumption, either ingested or used on the skin.

What materials are the plastic tanks manufactured from?

Plastic water tanks can be made of lots of different materials, however the majority of tanks we offer are made from either a medium density polyethylene (MDPE) or a high density polyethylene.

What outlet do I require?

The majority of our water tanks come with an outlet as standard. We can offer a range of water tanks where the tanks can either ‘Drilled’ or ‘Undrilled’. ‘Drilled’ meaning allowing water to escape from the tank via the outlet, whereas ‘Undrilled’ is when the outlet will remain sealed, preventing liquid from coming out and ensuring the contents of the tank is only touching plastic.

If the position of the outlet is required in an alternative position to the standard one offered or extra to the one positioned, we can offer a plastic Fusion socket. This can be welded anywhere on the tank using a drawing supplied by us, positions marked out by you, then fitted by the manufacturer.   

Plain tanks (with no outlets) can also be offered.

If you require a plastic fusion socket or a plain tank, then please contact our Customer Service Team, who will be happy to help with your requirements.

Tap or hose tail kits, what’s the difference and when would I need one?

We offer a range of tap kits, each displaying the size of the hosetail and the outlet size the kit will suit. Tap Kit 5 (TPK5) is the best solution if you require a garden hose to be fitted. Our range of Hosetail kits allows you to attach a hose or pipe to the tank, leak-free. They are designed for continuous flow and come in varying sizes depending on the outlet.

All our tap kits come with a Jubilee clip and PDFE tape for that secure fit.

What’s a standard hose pipe size?

UK hose pipe diameters range from ½” to ¾” inch diameters. The majority of standard size garden hoses are 3/4” BSP, however we do offer accessories for the ½” hose, if required.

Baffled Water tanks, what are they and when are they recommended?

Baffled water tanks are tanks with an intergral wall system, which is primarily designed to strengthen and support the structure of the tank, when the tank is full of water.

Due to the structure of the baffles they can also be used for transporting water. The Baffles distrupt the movement of water, from surging from one side to the other. However, if you are transporting water, water tanks can be extremely hazardous when transporting large volumes of water. Please make sure the water tanks are installed and secured correctly, by a suitable qualified person before transportation. Baffled water tanks are an ideal solutions for car valeters, window cleaners or anyone who has to transport liquids using plastic water storage tanks and containers.
