ST3800: 3800 Litre Harlequin Septic Tank
3800 litre (approx. 800 gallons) septic tank.
This tank is suitable for use where an effluent treatment plant is not required and serves a population of 5-10 people.
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.
Harlequin septic tanks aree based on a two chamber design with a long flow path which ensures a high degree of settlement and sedimentation, 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 50mm 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.
Manufactured from high grade polyethylene this Harlequin tank is corrosion resistant, has high impact strength and is UV stabilised. All Harlequin tanks are CE marked and comply with the latest European standards

As there are guidelines in place to minimise the risk of oil leaks, there are statutory requirements that
tanks or appliances used for the storage and access of oils are installed by a suitably competent
person and in accordance with the manufacturer’s installation and maintenance instructions.
Where electrical connections are essential with an installation, these must be undertaken by a
Any poor installation or not by someone who is suitably qualified could contribute to invalidating any
warranties held on a product.
Where such an installation is required, we strongly recommend that arrangements with a third party are
not made for the installation until products have been received. We aim to provide realistic delivery dates,
but delays are often the result of factors beyond our control (weather, traffic jams) and hence we cannot
be held liable for additional installation charges caused by any delays in you receiving the products
As Tanksrus have a suitably qualified installation team, if our installation is employed then it may be
easier to finalise a mutually convenient installation upon delivery.
Should at any point you feel the need to complain, then please contact Tanksrus via 01469 531229
