Above Ground Waste Storage Tanks

These tanks provide a superb solution for storing large volumes of waste when access to a mains sewer or waste treatment plant is not available.

The construction industry, for example, tends to use toilet waste tanks on remote or greenfield sites where there is no mains sewer. New and/or remote construction sites might typically use a potable or non-potable water tank for their water supply, connect this to their site accommodation (kitchen, toilets, showers), and then collect the subsequent waste in a toilet waste tank - all off-grid.

By the same token, the outdoor event industry may put toilet and sanitation facilities in place for large crowds at off-grid locations. In many cases, the volume of waste created over short periods of time (e.g. toilet visits during concert intermissions) may require additional storage, in which case large above ground storage tank are connected to toilet blocks or are placed on site as waste transfer stations.

Capacities range from 2,500 to 30,000 litres (500 to 6,000 gallons) but if that is not enough, you can also link these tanks together to create additional volume.

These waste tanks can be configured in many ways, with:

  • fittings to get the waste into the tank
  • drain valves to allow waste removal when the tank is full
  • breather valves and bolt down feet
  • liquid level sight glasses and linking kits...

If you're interested in using an Above Ground Storage Tank for any of the above applications of if you have any questions, please get in touch! You can also download our product and accessory sheets for even more detail.

  • Bracketed Weight Column items denote heavier gauge material to contain liquids up to 1.5 SG e.g. slurry, toilet waste.
  • We use differing grades of plastic and vary the tank wall thickness to match the tank to your application.
  • Please note: tank sizes quoted are subject to a +/-3% variation as they expand and contract relative to temperature.
  • We reserve the right to amend the technical specification to improve the product without prior notification.

Technical Advantages

  • Built in lifting points
  • Flat base for stability
  • Self-supporting roofs for added strength
  • 620mm vented lid

MULTIPLE APPLICATIONS

  • Bulk waste storage (e.g. flushed toilet waste, recirculating flush portable toilet waste)
  • Large waste transfer stations at events
  • Emergency waste storage when no mains sewer or waste treatment plant is available

UpgradeS & CONFIGURABLE OPTIONS

  • Tank linking kits
  • Filling options - from ball cock float valves (water) to "up and over" pipework (pumped toilet waste)
  • Sight glass / level gauge options
  • Recommended venting options when filling/evacuating > 500 litres per minute
  • Bolt down feet for added security, especially on exposed sites
  • Bunded tanks for spill protection
  • Tank insulation - 13mm & 25mm

Warnings

  • Toilet waste contains faecal matter and toilet paper/tissue, which increase the specific gravity of the liquid.
  • Waste from toilet cisterns (4-6 litre flush) will have a lower SG than waste from recirculating systems, which use less water.
  • This waste is variously known as black water / sewage / toilet sewage / slurry etc.
  • Tanks for slurry are termed as "industrial" and are 150% of the weight of standard non-potable and potable water tanks.
  • If you are handling / managing toilet waste, we recommend you opt for our "Slurry" tanks - thicker walls and increased weight.
  • Industrial / slurry tanks are made with increased wall thickness catering for specific gravities of contents up to 1.5
  • Any tank with heat-welded flanges / fittings will require a slurry/industrial tank
  • Consider bunded tanks to avoid spillages. Biggest bunded tank is 10,000 litres.
  • DELIVERY IMPLICATIONS OF LARGE TANKS
  • Delivery on a 44 foot articulated lorry
  • It is the customer’s responsibilty to offload
  • A HIAB truck may be required
  • Delivery is kerbside only - the delivery driver is not indemnified to install the product
  • Only lift or move when empty
  • PLEASE CONSULT OUR LITERATURE ON CORRECT INSTALLATION OF TANKS:
    PAY PARTICULAR ATTENTION TO THE BASE REQUIRED TO SUPPORT THE TANK WHEN FULL - WE RECOMMEND A CONCRETE BASE
  • Tank base should be a minimum of (600mm) (24") larger than the diameter of the tank and should have a minimum depth of:
    > 102mm (4") for tanks up to 2,500 litres
    > 152mm (6") for tanks 4,000 litres to 10,000 litres
    > 204mm (8") for tanks over 10,000 litres

Vertical Waste and Water Tank. Easy to linkDraining option: tanks are typically drained, emptied or connected to pumps from fittings at the base. Available with a range of connector types, valves and sizes. Filling option: "up and over" pipework to safely fill tanks from the top. Pipework is secured to side of tank and typically terminates 4' / 120cms above ground for ease of connection.Venting option: it is best practice and extends tank life by ensuring tanks are vented to equalise pressures, especially during rapid emptying or filling.Linking option: tanks can be linked to increase capacity or for site-specific requirements. e.g. accept larger water deliveries or extend period between waste removal.Site glass option: external clear tube "cat and mouse" gauge shows the level of liquid inside tank using a ball and float system for easy monitoring.Anchoring option: bolt down feet anchor tank(s) to a solid base to prevent movement. e.g. on exposed sites.Bunded option: a tank within a tank. For main tanks up to 10,000 litres, a larger external tank will catch any leaks and prevent an environmental spill.Depiction of typica tank sizesBilkhead fittings for plastic tanksExpansion joints for bunded tank connectionsWelded tank flanges PN16Ball valves for emptying waste tanksLinking pipework and ball valves between large vertical tanksMushroom vents for pressure equalisation in large tanksBolt down feet for security on exposed sites
