Septic Systems - A Short Story

By Gil Strachan
No. 7;  415 words

What would inspire me to write about septic systems? Maybe it's part in parcel with my fascination with composting and recycling?  Maybe I'm just a garbage hound at heart!  No - seriously, it's more that my travels as a home inspector have led me to focus on these delightful systems. I don't think I'll ever opt for a career in septic inspection, but I have gained a basic understanding of what constitutes a normal, functioning sewage disposal system.

Installing a private septic for a rural home includes soil tests, site inspections and considerable excavation work. Because of the design considerations and the amount of digging required, you probably wouldn't want to build your own; but to maintain it properly, you should know how it operates. Waste is piped out of the house into one side of a cement box called a septic tank, where bacteria break it down into solids (sludge), liquid (effluent), and scum. The sludge sinks to the bottom, the scum floats to the top, and the effluent flows into the other side, and then out through perforated pipes (drainage tile) buried in a leaching bed of loose gravel (also known as the septic field).

"Sewage and The Law!"

Government regulations specifically prohibit any renovations or additions to a home which are likely to affect the operation or effectiveness of a sewage system.  If you're on a septic, adding a bedroom to your house (even without adding a bathroom) might mean having to increase the size of your tank and field.  The regulations further state that any construction or alteration of a septic requires a Certificate of Approval issued by the Ministry or department responsible.

If you have questions about the care and operation of your septic system, call your Municipal Office, Health Department, Environment Canada, or any licensed sewage contractor listed in the Yellow Pages.

There's no hard and fast rule for pumping intervals, but an inspection and pump-out every third year are recommended. Don't allow meat by-products or harsh chemicals to enter your septic, and avoid the use of commercial tank cleaners or treatments. Don't plant trees on the field, and never drive over it!

By the way, greener grass over the septic is NOT usually a good sign!
