Atlantis 2600 Litre Potable Underground Water Tank
The Atlantis 2600 Litre Potable Underground Water Tank is a durable, space-saving solution for storing drinking water below ground. Manufactured in the UK from high-quality rotationally moulded polyethylene, this tank is designed for domestic, commercial and agricultural applications where a reliable supply of potable water is required.
Ideal for storing mains water, harvested rainwater following appropriate treatment, and water collected from private supplies such as wells or boreholes, the tank provides a dependable underground water storage solution while helping to maximise available outdoor space. Its robust ribbed construction delivers exceptional structural strength and, in many standard installations, allows the use of an environmentally friendly pea gravel backfill, helping to eliminate the need for costly concrete encasement.
The shallow dig design makes installation quicker and easier than many traditional underground water tanks, while also making it particularly suitable for areas with higher water tables. Its smooth curved base directs water towards submersible pumps, improving water recovery and reducing the amount of water left inside the tank.
Manufactured in the UK and backed by a 10-Year Manufacturer’s Warranty, the Atlantis 2600 Litre Potable Underground Water Tank provides a reliable, long-lasting solution for underground drinking water storage and potable water applications.
