We are often called upon to review failing systems, approximately 30% of homes in Canada are on an onsite waste water treatment system, and many of them are reaching the end of their lifespan. Although septic system lifespans can vary depending on soils and designing factors we can determine wether or not the system is in its final stages. This type of inspection service is very valuable to a homeowner during the inspection of a home being purchased. Often we can help add a little more time to the system by adapting an effluent filter to the existing septic tank. This would mean a minor excavation exposing the tanks, then adapting ‘T’ fitting to the outlet pipe so that a filter can then be placed inside.
