Product Description

Suitable for domestic use by 5-8 people, this NEO Rainwater Harvesting Tank is robust, lightweight and long-lasting.


  • 8000 litre-capacity
  • 100% recyclable
  • Easy installation
  • Lighter than comparable flat tanks
  • Bionic design
  • Made from 35% recycled material
  • Rainwater harvesting or septic waste

The tank is inspired by biological methods and systems found in nature meaning it features a bionic design. It is modelled on the nautilus shell which, though thin, can withstand water pressure to depths of up to 800m. This is the first rainwater harvesting tank to have such a design.

Its pump basin (also known as a sump) makes optimal use of the tank volume. It is a solid unit without seams or welds and can be placed in groundwater, up to 1/3 of the tank’s height. A concrete backfill is not required, saving both time and money.

It is constructed using 35% less plastic than its previous F-Line model. As a result, the tank is lighter but still upholds the same outstanding structural properties that allows it to withstand considerable water pressure. It is suitable for rainwater harvesting or to be used as a septic tank.

The reduction in plastic-use and its part recycled construction makes the NEO tank environmentally-beneficial in its production, transport and use.

It’s lightweight and flat design requires only a shallow excavation pit. This reduces the excavation area as well as installation costs.


  • NEO flat tank
  • Filter shaft FI-2 (2-way filter that automatically flushes leaves and dirt into overflow) incl. filter housing with integrally-moulded siphon, stainless steel wedge wire screen and calmed intake)

  • Walk-on tank cover
  • Submersible pressure pump diver
  • Labelling set
  • Automatic water mains top-up kit (sends mains water to the tank in the event that the tank runs dry) WRAS-approved product 1306031

Rainwater Harvesting FAQ's

What is rainwater harvesting?

Rainwater harvesting is the collection of rainwater directly from the surface or surfaces upon which it falls. This water would otherwise have gone directly into the drainage system or been lost through evaporation and transpiration. Once collected and stored, the rainwater can be used for non-potable applications such as toilet flushing, garden watering and washing clothes using a washing machine.

Why should I consider a rainwater harvesting system?

Despite the common perception that it rains a lot in England and Wales, water resources are under pressure. Demand for water is rising due to the increase in the population, changes in lifestyles and due to the impacts of a changing climate.

In the South East of England, where large numbers of people live and work, water is scarcer than anywhere else in England and Wales. In fact there is less water available per person in this region than in many Mediterranean countries.

What savings can be achieved by using a rainwater harvesting system?

Any rainwater harvesting system will reduce your dependence on the mains water supply.

Potential savings should be assessed on an individual basis before any system is implemented. Factors which will influence this are; the demand for non-potable water, the amount of rainwater that can be collected and whether the property is charged by volume of volume used.

Savings will be higher in commercial/industrial buildings and schools. This is due to these types of buildings having much larger roof areas and a much greater demand for non-potable water compared to private dwellings.

Financial savings are usually higher when a system is installed during construction of the premises as retrofitting a system can be expensive as well as disruptive.

What are the benefits of using a rainwater harvesting system?

A rainwater harvesting system will reduce the demand for mains water and relieve pressure on available supplies. Reducing the volume of mains water supplied means that less water is taken from lakes, rivers and aquifers and more is left to benefit ecosystems and help sustain the water environment.

A rainwater harvesting system can also reduce the risk of flooding and pollution as less rainwater is discharged to drains and sewers and, ultimately, to rivers. They can contribute to slowing down the flow of water and reduce the pressure on drainage systems in times of high flow.

How much water do I need to store?

The tank is often the most expensive part of the system and choosing the right size is key to minimising costs. The tank size needs to be a balance of cost and storage capacity. The tank should also overflow at least twice a year to flush out floating debris.
