The base of the tank is flat which helps with installation however allows complete drainage of the tank when cleaning. The cover is load-bearing and unobtrusive to pedestrians and is retained using a single bolt and can be removed completely to provide a clear and large sized access. Above ground it does not impede on available space which can be used for more diverse, practical and imaginative purposes. Tank body is a seamless, one-piece moulding eliminating on-site assembly and guarantees internal cleanliness. Flat base for stability and integrated lifting points for ease during handling and installation. Carefully designed, the tank has no potential air pockets or base ribs to reduce working volume therefore using the entire capacity. Surface water is directed down past the lid and turret to soak away into the surrounding soil.

The pump is pressure-sensitive, (turns off if no demand), dry-run protected, (cuts off if no water detected), pump for extended service life. Legislation Complies with BS8515 Rainwater Harvesting Code of Practice and Building Regs (Part G), and often vital to planning approval by assisting compliance to environmental guidelines such as The Code for Sustainable Homes and BREEAM. Easy to install, this tank only needs shallow excavation with no concrete backfill resulting in reduced installation costs. The overall design of the tank is aimed at reducing costs from delivery to installation and from day-to-day use to annual maintenance.

The filter situated at the pump and inlet, is low maintenance and self cleaning, a check but once a year would suffice.

Lead Time: The lead time on waste oil tanks is estimated at 3-4 weeks.  This will be confirmed at the point of ordering.
