Examples of what rainwater can be used for include;

  • Flushing toilets
  • Washing clothes in washing machines
  • Plant watering
  • Washing your car

Rainwater Harvesting Water Tanks

Rainwater Harvesting Water Tanks. ‘Rainwater harvesting’ is a term used for the collection, storing and distribution of rainwater for a wide range of uses both commercially and domestically. Collecting water in this way allows the re-use of a valuable resource therefore reducing demand on a mains supply. Examples of what rainwater can be used for include;
  • Flushing toilets
  • Washing clothes in washing machines
  • Plant watering
  • Washing your car

How Do Rainwater Harvesting Water Tanks Work?

Most water tanks for rainwater collection have a number of common features such as;
  • An inlet for the rainwater to flow into
  • A filter to remove debris
  • Overflow
  • Outlet
Consequently, the simplest form of rainwater harvesting is to collect rainwater in a Water Butt through connection to an external guttering downpipe. This is an ideal solution in a domestic setting as a Garden Rainwater Tank. To illustrate how these systems work, Enduramaxx have created a very useful animation of a Rainwater Tank in action.

What types of Rainwater Collection Tanks are there?

Water Butts Typically found in a garden, a water butt is an ideal size for domestic purposes. Primarily designed to connect to residential or outbuilding downpipes, they are easy to set up and install. Rainwater collected by your water butt can be used to water your garden, therefore offering an instant saving on your water bill and reducing your demand on the mains supply. Above ground Rainwater Tank The most common type of tank for this purpose. The tanks can be sited next to the downpipe/guttering they are collecting water from. A wide range of capacities are available, up to 30,000 Litres. Suitable for domestic and commercial applications, the tanks can also be joined together for additional capacity. Various shapes of tank are available - from rectangular rainwater tank above ground tanks to round tanks. Are you restricted on space and can't find what you are looking for? Get in touch with the dimensions you have here. Underground Rainwater Tank Useful for when space is limited above ground, an underground storage tank is a great space saver. Ideal to install during a new build development to promote its green credentials. Our range also includes an underground water tank system that only requires a shallow excavation - view here. Rainwater Tank Systems In the same way as the tanks above, the rainwater systems offer a rainwater storage solution but with the additional benefit of a pumped outlet and filter within the tank itself. As a result, the system comes ready to fit.

What accessories do I need?

Rainwater Tank Filters Without appropriate filtering, leaves and debris can enter a rainwater tank and consequently cause blockages. In addition, dirt can collect at the bottom of the tank. The rainwater tank filters help to remove leaves and debris before it has a chance to enter the tank. These filter kits are ideal for the larger capacity tanks where access for regular cleaning is limited. Tank Joining Kits Looking for additional capacity? Our tank joining kits will allow a number of tanks to be connected, therefore doubling your rainwater collection capacity. Additional outlets These outlet kits mean additional water tank outlets can be added where required. This is particularly useful if you wish to add an additional outlet for a tap, as an example.

Water Tank FAQs

‘Potable’ is a term used to describe a tank suitable for storing water for human consumption. To be classified as potable, the plastic it is manufactured from must conform to the WRAS (Water Regulations Advisory Scheme). For more information on this, please visit the WRAS Approvals website here where they have an information titled ‘What is a WRAS Approval?’.

All our potable tanks adhere to these regulations. It will specify if a tank is potable in the Product Specification section on each product page.

Water Storage Tanks are used across many different industries, which can make purchasing the correct one a little daunting.The following guide may be useful to you – ‘What Water Storage Tank Do I Need?.

Still Unsure? We are always willing to help – just give us a call or contact us here.

Each tank comes with a outlet as standard. The plastic behind the outlet can be removed (‘drilled’) to allow the liquid to run out of the tank and through a tap if you have one fitted. It can also be left ‘undrilled’ which means it remains closed and the liquid cannot come out through this outlet. You may wish the outlet to be left undrilled if you plan to use the tank purely to store water, as an example.

It is possible to choose ‘drilled’ but purchase a ‘plug’ for the correct size outlet which will seal the outlet when required but allow for flexibility in the use of the outlet. Another option is to choose to have the tank ‘undrilled’ and remove the plastic yourself at a later date.

Yes, planned viewing is possible at a number of locations. Please call and allow us time to arrange this for you.

From experience, our customers favor the Baffled Water Tanks for this application.

A Baffled Water Tank has pre-moulded internal walls called ‘baffles’ which helps to control the movement of the water in the tank during transportation of liquid. This also helps to improve the vehicle maneuverability.

The size of tank required is completely dependent on the size of your vehicle and the set-up you require. The most popular Baffled Water Tanks are as follows: 210 Litre upright, 250 Litre upright350 Litre upright and the 400 Litre upright water tank. We do have customers who prefer the larger tanks so this is also an option.

The Baffled Water Tanks are also suitable for use with water-fed poles.

Yes. This is possible by using a ‘fusion’ and are available in a number of sizes to suit your application or project. View the range here or read our Fusion Socket Guide here for more information. Just add the required fusion onto your order and once complete, we will be in touch to arrange placement of the fusion/s.

Each Water Storage Tank comes with either a ‘Vented’  or a ‘Plain’ lid as standard.

A vented lid allows air to circulate within the tank, helping to control the pressure within it. This is important if you plan to attach a pump to the tank as without this, the pressure may cause the tank may deform. Often, this type of damage is not repairable.

A plain lid is purely for containing the water and stops air getting into the tank.

See below for an example of either type (Note – the lid may look slightly different depending on what tank you are looking at. Please refer to the individual product for details).

8 Inch Plain Lid
8 Inch Spring Vented Lid

In most instances, it is possible to swap a lid for an alternative but please contact us before ordering unless it is offered as an option on the product page.

Yes, we are able to manufacture the majority of the Water Tank range in a wide variety of colours. You can view our Colour Chart page here

This is no problem, the only consideration you may wish to make when using saltwater is whether you would prefer to use a plastic outlet (know as a fusion) rather than the brass or nickel outlet that come as standard with the range. If this is the case, all you need to do is request that you tank comes 'undrilled' which will ensure a plastic 'wall' separates the metal fusion and the tank contents. The plastic fusion can be added almost anywhere on the tank. Just choose the fusion you require and add to your basket along with the tank. Once your order is placed, we will then in touch to discuss where you wish your plastic outlet to be placed.

The Byelaw 30 Kit is specifically used when connecting a tank to mains water supply. With an insect proof screened vent, as well as preventing backflow of the stored water into the main s(potable) supply, it helps to prevents contamination A Byelaw 30 Kit is required in order to conform to the Byelaw 30 Regulation as it helps to maintain the quality of the water in the tank.
