WTE QUANTUM 8-Person Sewage Treatment Plant
The QUANTUM 8 is a compact sewage treatment solution designed for domestic properties with a design population of up to 8 people. It provides additional treatment capacity over the QUANTUM 6 while retaining the space-conscious design that characterises the range.
With a tank diameter of approximately 1,500 mm, the QUANTUM 8 offers a practical balance between treatment capacity and installation footprint. This makes it suitable for larger family homes and other domestic properties where a compact treatment plant is required without moving to a significantly larger tank design.
The plant has a standard installation depth of around 2 metres, with an optional extension turret available where site conditions require a deeper inlet level. This allows the unit to be adapted to suit a wider range of existing drainage configurations.
The QUANTUM 8 is an excellent choice for larger family homes, properties with multiple bathrooms, and domestic applications requiring greater treatment capacity.

Delivery Terms
Estimated Lead Time: 2-3 Working Days
The delivery of a tank can be confusing as each manufacturer offers a slightly different service and lead time. Please refer to our Delivery Information page. Standard tank deliveries are "kerbside", which means the tank will be delivered to the kerb only and not positioned further. Should you have specific delivery requirements or restrictions, please contact us to discuss.
Tanks over 2,500L — articulated lorry, customer offload
These tanks are delivered on an articulated vehicle (approximately 16.5m long × 2.6m wide × 3m high) which has no offloading on board. It is the customer's responsibility to offload the tank, which may require a telehandler or forklift.
Curtain-sided vehicles are also used, so please note that if there are obstacles or overhanging branches on the road to the delivery site, the driver may refuse to drive to the location due to the risk of damaging the vehicle. Please let us know about any obstructions before delivery so we can arrange alternative transport.
18-tonne tail-lift HGV
This vehicle is roughly the size of the largest bin lorries — approximately 8.2m long × 2.6m wide × 4m high, and often curtain-sided. If there are overhanging branches, these vehicles will not attempt the route, so a smaller vehicle should be requested.
Tanks are lowered to the ground but not positioned, as this is a kerbside delivery. If a smaller vehicle is required, email sales@fueltankshop.co.uk quoting your order number and name.
HIAB delivery
HIAB delivery is available but must be requested, and carries an additional cost. Email sales@fueltankshop.co.uk quoting your order number and name, and we'll come back to you with a price.
Accessories
Most accessories are delivered within 1–3 working days. Certain products and postcodes may take longer — check the product page for current information. If you need them sooner we can sometimes offer a next-day service; please contact us to discuss. If an item is out of stock we'll advise the expected lead time, and you're free to cancel for a full refund.
Returns Information
Customers may return items within 14 calendar days, as set out in section 7 of our Terms & Conditions.
All items must be returned unused. Refunds cannot be issued for used or previously installed items.
Please be aware that returning a tank can be complicated and expensive, so do check you're ordering the correct item — we strongly suggest checking the dimensions carefully before you buy.
