4500 Litre septic tank

A septic tank is designed to provide what is known as primary biological treatment to crude sewage produced in a normal domestic environment. It retains solids and allows them to settle out, where they can be partially broken down by biological action so that only the remaining liquor is left to flow down the outlet drain. This liquor (normally called effluent) is then sufficiently treated to soak into the ground in an underground distribution system.

Design features

Balmoral septic tanks are designed in accordance with British Standard Code of Practice BS6297 and are based on a two chamber design with a long flow path which ensures a high degree of settlement and sedimentation, thus providing a low level of suspended solids suitable for discharge into an underground soakaway system.

The system of baffles ensures that no crude solids escape into the outlet drain, avoiding premature blocking of the soakaway system.

The tanks have Ø50mm moulded-in lifting eyes for use during handling and installation (only when the tank is empty).

The inlet and outlet pipe work is specially designed to disperse any noxious or inflammable gases into the atmosphere through the drainage ventilation.

The standard septic tank is designed to cater for drain invert depths of 770mm. The neck can be reduced to suit shallower invert depth.

The inlet pipe can be rotated by 180° to line up with the drainage lines from almost any direction.

A fully lockable pedestrian duty manhole cover is supplied as standard to comply with statutory regulations.

A safety grill can also be supplied as an optional item to fit across the access shaft as an additional safety feature.

The tanks have a flat base for stability during transportation and storage prior to installation.

Access for 55' Artic required or extra cost for alternative vehicle

Site will require means of lifting tank from artic, fork lift or digger

Balmoral septic tanks are tested and approved by the British Board of Agrément (cert. no. 94/3021).
