How much can an on-site wastewater system cost a property owner? 

Costs for on-site systems are highly variable, depending on a number of factors including aggregate proximity & cost, soil type, gravity versus pumped, house size and number of fixture units and bedrooms in the home. A typical installation of a conventional in-ground gravity system for a 3 – 4 bedroom house can be anywhere in the range of $15,000 to $30,000. A typical installation of a conventional fully raised gravity system for a 3 – 4 bedroom house can be in the range of: $20,000 – $40,000. An advanced treatment system for a typical 3 bedroom home will range from $25,000 to $50,000 plus maintenance contract costs.

Is an alternative treatment unit worth its cost?

Costs may range from $25,000 to $50,000 for a complete system. Keep in mind, however, that in some remedial applications on small lots there is only enough room for an alternative system. Also, the cost of a conventional system in some applications (very wet or stony lots) can far exceed the cost of an alternative system.

What is the cost of fixing an on-site system?

Proper maintenance of a system can increase the lifetime of the system and save the homeowner money: Estimated costs for repairs are as follows (assuming a contractor does the work:

  •  Replacing a clogged leaching bed: $15,000 – $25,000;
  •  Replacing a tank (installed cost): $8,000 – $15,000;
  •  Cleaning out laterals: $ 5,000 – $ 12,000.

A well maintained conventional system lasts 20 – 25 years

What is the cost of a permit?

The cost of the permit will vary from region to region across the province, however it can be anywhere from $500 to $1,000.

How much will it cost to pump out my tank?
