Buying guide

Choosing the right Rotosat water tank

Safely store mains or borehole water: our Rotosat Industry tanks are made of food-grade high-density polyethylene, built for long-lasting household use. Here's what matters before you order.

Before you buy

Food-grade high-density polyethylene

Rotosat Industry tanks are made of food-grade high-density polyethylene, with no risk of contaminating the stored water, unlike some cheaper materials.

Anti-UV treatment and vertical installation

An anti-UV treatment protects the tank from Tunisia's strong sun and prevents the plastic from ageing prematurely; our vertical models keep the footprint small for courtyards and terraces.

Single, Double or Triple-Layer Water Tank: What's the Difference and Which to Choose?

A drain valve for upkeep

A drain valve at the base lets you empty and clean the tank periodically without tipping it over or manually pumping out the last of the water.

Frequently asked questions

What tank capacity should I choose?

Capacity depends on how many people are in the household and how often water cuts happen in your area; estimate your daily consumption and multiply it by the number of days of reserve you want to keep.

Why do food-grade quality and anti-UV protection matter?

Food-grade quality ensures the stored water doesn't pick up contamination from the plastic; anti-UV treatment shields the tank from sunlight, which otherwise makes untreated plastic age and crack when installed outdoors.

How do I install and maintain a vertical tank?

Set it on a flat, stable base that can bear the weight of the water once full, away from anything sharp; use the drain valve to clean it once or twice a year and avoid letting water sit stagnant for too long.
