Enduramaxx static horizontal water tanks provide above-ground storage where a lower profile is more suitable than a tall vertical tank. Typical uses include irrigation, rainwater harvesting, process water, wash-down supply and pump or booster storage.
5,000 litres and above: price on application
For tank options of 5,000 litres and above, please request a quote before ordering. We will confirm the tank price, delivery to your postcode, site access and offloading requirements. These sizes are not available to buy online. Smaller sizes remain available to order at the displayed price.
Tank dimensions by model
Nominal dimensions in millimetres. L = length, W = width, H = height, Ø = diameter. Updated rows use Enduramaxx drawings and clarification supplied on 2 November 2026; other rows retain existing manufacturer specifications. Read each row’s measurement and configuration notes. Allow installation and maintenance clearance, including the manufacturer’s ±3% tolerance where stated. Nominal lid/cover size is not the clear access opening.

Important selection information
These are static storage tanks, not transport tanks. Confirm the exact variant's water suitability, usable capacity, lid and connection arrangement before ordering. Plan a flat, continuous load-bearing base, installation access, overflow, ventilation, frost protection and offloading. Do not rely on the tank colour or material alone to determine potable-water compliance.
Manufacturer installation guide
Download Enduramaxx’s above-ground static tank handling and installation guide (PDF). Check support, base, handling and flexible pipework requirements for the selected tank.
Tank outlet and blanking cap
The standard tank connector/outlet has a male BSP thread. See the specifications for the outlet size of your selected tank.
A red protective cap is supplied on the outlet. If you will not be using this outlet, a matching female BSP Hansen cap must be purchased separately to blank it off. Choose the same nominal BSP size as the tank outlet.
