from £797.33

The Graf Platin Shallow Dig Underground Tank is a high-quality, multipurpose tank designed for minimal excavation and maximum versatility. Ideal for residential and commercial applications, it can be used as a cesspool, rainwater storage system, or wastewater storage tank.

Available in sizes 1500L - 7500L

  • Multipurpose Storage Capacity: The Platin Underground Water Tank is expertly crafted to handle a diverse range of storage needs, including non-potable water, wastewater, raw sewage, effluent, silage, slurry, rainwater, greywater, and bluewater. This versatility makes it an indispensable solution for residential, agricultural, and industrial settings, facilitating efficient management of liquid resources and waste

  • Convenience of Fully Assembled Delivery: Platin Tanks are delivered fully assembled, dramatically reducing installation time and complexity. This pre-assembly ensures each tank is ready for immediate use upon arrival, streamlining the setup process and reducing the potential for error, which can be critical in urgent or time-sensitive installations

  • Exceptional Groundwater Stability: Designed to be groundwater-stable up to the tank shoulder, the Platin Tank features a highly stable construction that withstands environmental pressures, preventing water ingress and structural damage. This stability is crucial for long-term reliability and performance, particularly in areas with high groundwater levels

  • Supplied with a mini dome as standard

  • Option for Pedestrian Lid or Heavy Duty Lid - vehicle loading up to 3.5t with a maxi tank dome (DN100 connection), composite plastic telescopic lid

  • Option for high level alarm with audio and visual warning to alert that cesspool is full (see accessories)

Cesspools should only be emptied by a registered Waste Carrier and hold a current discharge licence from the local water authority. We can assist with this. Please call the office for more details. If unsure - please call our friendly team.
