Product Overview

The new generation Roto Roterra 2450 underground water tanks have arrived in the UK, and they are impressive.

Roterra 2450 water tanks are easy to install, low maintenance and easy to clean due to the polyethylene material used.

Collecting rainwater can significantly reduce water consumption from the water supply system and so can save you money on utility bills, while also being eco-friendly.

The underground rainwater harvesting tanks can be supplied in 10 different sizes to suit all situations. If you need a larger system or want to expand your current system, simply connect the tanks together via the necessary pipework.

Rotarra 2450 Benefits:

Roto have designed the tank to increase the volume in relation to the surface area, acheiving a larger volume per unit of length. This helps to (i) reduce the cost of shipping due to being able to fit a 65,000 litre tank on a lorry, and (ii) reduce installation costs due to having to extract less soil. 

Loading and Unloading:

The water tank can be lifted with lifting straps in marked places within the ribs of the tank or removed by a forklift / telehandler. Please carefully check your vehicle and strap weight restrictions.


Tank Statics: 

The Roterra 2450 water tank is designed so that the forces of earth are at favourable angles, putting less pressure on the side of the tank. The sides are designed to be steep so the earth is transmitted away.


Tank Installation: 

The profile of the Roterra 2450 water tank gives an increased volume of tank in relation to its' surface area. Therefore, the tanks require a shorter construction pit and less backfill material during installation, reducing costs.


Tank Warranty:

It's very important to follow the instructions for installation in regards to fitting any underground water tanks. If fitted correctly, Roto tanks will last for 50+ years. The warranty provided on the Roterra 2450 is 60 months watertightness from the invoice date of the tank. Pre-conditions for warranty benefits are proper handling, assembly and installation according to the Roto guidelines. The warranty may become invalid if any of these conditions are breached.
