GRAF Platin 3000L Underground Potable Water Tank
The GRAF Platin 3000L underground water tank is certified food-safe for storing potable drinking water, making it ideal for private water supplies, boreholes, spring collection and mains-fed buffer storage. Its flat, low-profile shape is designed for a shallow excavation, so it can be installed on sites where a deeper dig would be difficult or costly.
Certified food-safe storage
The 3000 litre tank is manufactured from high-strength, corrosion-free polypropylene with smooth internal surfaces that resist deposits and are easy to clean. It carries certification for drinking-water contact and is engineered for decades of reliable underground service in potable applications.

Specification
- Capacity: 3000 litres
- Water type: certified food-safe potable water
- Tank style: Platin flat, shallow-dig underground
- Material: injection-moulded polypropylene

Installation
The Platin 3000L is bedded on a gravel base and surrounded with granular backfill, so most domestic installations avoid the cost and effort of a concrete surround. Its shallow-dig profile keeps groundworks to a minimum even where the water table is high, and the telescopic dome adjusts to bring the lid neatly to ground level.
Applications and Usage
The Platin 3000L is used for underground storage of drinking water on rural homes, farms, smallholdings and properties on private or borehole supplies, as well as buffer storage that protects against mains interruptions. The tank can be paired with GRAF filtration and pump accessories to build a complete private water supply.
Water quality and hygiene
Because the tank is certified for drinking-water contact and moulded in one seamless piece, there are no seams or corrosion points to harbour contaminants. The smooth interior can be inspected and cleaned with ease, helping maintain water quality year after year on private, borehole and rural supplies.
