Toilet Waste Storage - Above Ground

These tanks provide a superb solution for capturing and storing toilet waste at off-grid sites or when access to a mains sewer or waste treatment plant is not available.

The construction industry will 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 combination of potable water and non-potable water tanks for their clean water supply, connecting these to their site offices (toilets, kitchens, showers) and then collect the toilet waste in a suitably-sized waste collection tank, all of which are "off-grid."

By the same token, the outdoor event industry may put toilet and sanitation facilities in place to cater for large crowds at concerts and festivals.

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 but you can also link these tanks together to create additional volume.

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

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

  • S = Standard Tank | SL = Slimline Tank | LP = Low Profile Tank.
  • Toilet waste tanks have thicker tank walls (1.5 SG) than water tanks (1 SG)
  • 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

  • Made from a one-piece moulding using strong and durable plastic polymer (MDPE)
  • Robust, impact-resistant, long-lasting, UV-stabilised and rust free
  • Rotationally moulded in the UK using a heated, hollow mould filled with plastic polymer, guaranteeing consistent quality and dimensions
  • Cylindrical in shape with strengthening ribs
  • Lightweight plastic means manufacturing costs are less than their metal counterparts.
    The result is a product which is cheaper and easier to transport, and reduces your carbon footprint.
  • Available in a range of volumes from 2500 to 30,000 litres (550 to 6600 gallons) and in Standard, Slimline and Low Profile shapes. Tanks can be linked together to extend capacity.
  • An extensive range of accessories to configure the tank(s) for your site / application
  • Built in lifting points - for use when empty
  • Flat base for stability
  • 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 - "up and over" pipework (pumped toilet waste)
  • Sight glass / level gauge options
  • Venting options when filling/evacuating
  • 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.
  • 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. This is "tank within a tank" the largest of which is 10,000 litres.
  • DELIVERY IMPLICATIONS OF LARGE TANKS
  • Delivery on a 44 foot articulated lorry
  • It is the customer’s responsibility to offload - forklift truck / telehandler required
  • Larger tanks will be too tall to fit inside a curtain-sider vehicle and will need to be delivered on a flat-bed trailer
  • A HIAB truck may be required for delivery
  • 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 linkVertical 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
