Designed specifically for site welfare units and temporary sanitary facilities, our Double Mains Toilet Waste Tank provides reliable, high-capacity effluent containment where direct mains sewage drainage is unavailable. Manufactured in the UK from heavy-duty, corrosion-resistant polyethylene (or heavy-gauge welded steel), this low-profile effluent tank sits directly beneath dual mains-connected toilet blocks. Features multiple Bauer suction points for easy tanker emptying, integrated sealed inspection hatches, and high-strength lifting handles. Fully compliant with UK environmental health and site sanitation standards.

When operating temporary construction sites, outdoor events, or remote welfare facilities, connecting directly to a public sewer line is not always feasible. The Double Mains Toilet Waste Tank acts as a high-capacity, low-profile effluent holding system designed to slide directly beneath dual-block mains toilets or portable welfare cabins.
By storing blackwater and sanitary waste safely above ground, this tank eliminates the need for costly sub-surface excavation while ensuring full compliance with UK environmental regulations regarding waste containment.
Space-Saving Footprint: At just 450 mm high, the flat-top profile allows double mains toilet cabins to sit directly on top, utilizing gravity feed for waste disposal without requiring additional elevation frames.
Heavy-Duty Structural Integrity: Engineered with reinforced internal bracing to support the weight of stacked toilet units and active foot traffic above.
Standard Bauer Connectors: Fitted with quick-connect Bauer suction points, allowing municipal waste contractors and vacuum tankers to pump out effluent quickly without spillages.
Odor-Sealed Access Hatches: Includes heavy-duty screw-down inspection lids to allow easy monitoring, cleaning, and sanitization while keeping odors fully contained.
Built using high-density polyethylene (MDPE) or epoxy-coated steel, preventing degradation from harsh sanitary chemicals, UV exposure, and freezing winter temperatures.

Offloading & Position: Units are lightweight when empty and can be positioned using standard forklift tines or crane lifting straps via integrated corner eyes.
Transport Clearance: Shipped flatbed or via HIAB lorry across the UK.
Ground Preparation: Must be installed on a level, hardstanding surface (concrete pad, asphalt, or compacted gravel) to ensure even weight distribution when full.
Emptying frequency depends on site usage. A standard 500-gallon (2,270L) double mains toilet waste tank typically supports a team of 10 to 15 site workers for roughly 2 to 3 weeks before requiring a vacuum tanker pump-out.
Yes. The low-profile flat top is structurally reinforced to support the static weight of standard double mains portable toilet cabins and welfare units.
The tank features standard 4-inch or 5-inch Bauer quick-release suction couplings, allowing commercial vacuum tankers to connect and pump out the waste without moving the tank or toilet unit.
