The Benefits of Underground PuraTanks
Atlantis’ PuraTanks range from underground water tanks, septic tanks, water treatment plants and rainwater harvesting systems.
The underground water storage PuraTanks are made from Polyethylene and formed using Rotationally Moulded Polyethylene, which produces a stress-free, robust tank. The polymer used contains additives that make the water tank UV resistant.
The underground water storage PuraTanks are available in a range of sizes, both potable and non-potable:
What are underground water tanks used for?
The underground water storage tank is mostly used for rainwater harvesting, although it can also be used for water attenuation and preservation from other sources such as wells and springs.
Rainfall can be obtained, stored, and pumped into equipment in both domestic and commercial potable and non-potable applications using a variety of options and accessories.
Underground tanks feature a curved design for higher efficiency when combined with submersible pumps, as it allows for the water from the bottom of the tank to be pumped out.
The following are several alternative applications for underground storage tanks:
-
-
- Filtered alternatives that allow drinking water to be used.
- Laundry and dishwashing.
- Bathing and showering.
- A tank used to store water for irrigation and garden watering.
- Underground fire cisterns are built to supply water for firefighting.
- Land water for crops and livestock.

What are the advantages of using underground water tanks?
Easy installation
The high-strength and ribbed exterior and shallow-dig depth allow for an easier installation, as well as being ideal for areas with a high water table.
There is no need to encase the tank in concrete; simply backfilling with pea gravel qualifies, making it an environmentally friendly solution.
They take up minimal room and can be installed under lawns or driveways.
Underground water storage tanks are not vulnerable to vandalism or tampering. They are not at risk during floods or other natural disasters and can be used in the aftermath where city water is unavailable.

Installation requirements or instructions will vary based on the model.
Reduce your mains water usage
Rainwater harvesting systems and water storage tanks are becoming very effective in reducing your dependence on mains water usage.
The water is primarily obtained from rain that falls on your house, and your existing gutters and downpipes are used to fill a tank where the water is purified and stored.
Water is either supplied directly to your home's points of use, or it can be fed into a secondary header tank in your loft to raise supply pressure.
Effortless upgradability
Since the PuraTanks do not need to be encased in concrete, upgrading the water tank is much easier and is as simple as digging a larger pit and replacing the tank.
PuraTanks are sold with a variety of equipment and accessories to accommodate a wide range of applications.
Are the underground water tanks for storing drinking water?
The potable version is suitable for drinking water as it uses WRAS Approved Polymer, whereas the non-potable version is not fit for drinking but can be used for a variety of other uses based on its consistency.
How long do underground storage tanks last?
Underground storage tanks are expected to last between 30 and 40 years.
The rate of corrosion and tank breakdown, on the other hand, is entirely dependent on tank type, construction, and site conditions.
For added peace of mind, the PuraTank series comes with a 10-year manufacturer warranty.
