The main difference lies in the material and certification. Potable tanks are made from food-grade, WRAS-approved materials safe for drinking water. Non-potable tanks are made from standard high-quality polyethylene that may be more porous or lack the specific linings required for human consumption, making them suitable only for 'service' water tasks like irrigation or cleaning.
These tanks are incredibly versatile and are used for rainwater harvesting, garden irrigation, livestock watering, commercial pressure washing, dust suppression on construction sites, and toilet flushing systems in off-grid or eco-friendly buildings.
Yes, non-potable tanks are excellent for watering plants and crops. Harvested rainwater is often preferred for gardening as it lacks the chlorine found in mains water. However, the water should not be used for drinking or washing food that will be eaten raw without further treatment.
Most of the tanks in this specific collection are designed for above-ground use and are UV-stabilized to withstand sunlight. If you require a tank to be buried, you should look at our dedicated 'Underground Water Tanks' range, which features reinforced ribbing to handle ground pressure.
Our non-potable range is vast, starting from small 100-litre garden tanks and extending up to massive 30,000-litre industrial units. For even larger requirements, multiple tanks can be linked together using a manifold kit.
If you plan to transport the water in a van or trailer, a 'baffled' tank is highly recommended. The internal baffles reduce water surge (sloshing), which prevents the weight of the water from shifting suddenly and potentially causing the vehicle to lose control.
Maintenance is similar to potable tanks but focuses more on preventing debris and algae. Because the water isn't for drinking, slight algae growth is less of a health risk, but it can still clog pumps and filters. We recommend using a dark-coloured tank (like black or dark green) to block sunlight and reduce algae growth.
No. Once a tank has been manufactured and used for non-potable purposes, it cannot be certified for drinking water. If there is any chance you might need the water for human consumption in the future, it is safer to invest in a WRAS-approved potable tank from the start.
