Description: a filter, installed at the outlet of septic tank. This filter dramatically improves the quality of effluent discharged to the leaching bed. It is strongly recommended that an effluent filter be installed on all systems Intended Use: Improves effluent quality Extends leaching bed life Details: Can be used in any septic tank - either as a new installation or retrofitted to an existing installation Simple maintenance (some filters come with an alarm that indicates when they need cleaning) Cost about $300 plus installation Available from most licenced septic suppliers and tank manufacturers Description: A sand or wood chip filter is placed between the septic tank and leaching bed to improve effluent quality prior to discharge to the leaching bed. Intented Use: Environmentally sensitive areas Prolong the life of the leaching bed in impermeable soils Details: The filter ranges from 3 m to 6 m square. It is enclosed by plastic PVC and buried beneath the ground. A pump is used to deliver the effluent to the leaching bed. Adding a filter doubles the cost of a typical septic system (a conventional leaching bed costs $23 - $33 per metre of trench). Sources: Sand Filtration Inc, Kitchener, Ontario. Tel: 519-743-1780 OSI Onsite Sewage Inc., Kitchener, Ontario, Tel: 519-578-0969 Description:These units can be installed either ahead of or after the septic tank. Air is pumped into the sewage to increase aerobic microbe action. A mechanical pump is used for aeration. Intented Use: Prolong the life of the leaching bed May be installed in a new system or an existing system Details: Air is stirred or bubbled into the waste to break down the material. The liquid is discharged to the leaching bed. The sludge must be periodically pumped from the tank. Cost is up to $10,000 Sources: Northern Purification Systems, Ontario.

Tel: 905-850-7234 Northern Purification Systems, Ontario. Tel: 905-729-3212 Description: A long, narrow probe with pneumatic hammer penetrates the soil. Compressed air is injected to fracture the soil. Dry polystyrene pellets are injected into the cracks in order to maintain the passageways. The process works best in soils that allow cracks (i.e. heavy clays) Intented Use: Prolong the life of an existing leaching bed Details: The cracks created by compressed air can extend to depths of 90 cm. The system causes no damage to lawns. Site evaluation by licenced installer with experience using the Terralift system is required. Cost: $3,500 for a three-year guarantee system Sources: Terralift Inc., Stockbridge, Mass, U.S.A.
