Septic tank and drainfield installation

Whether you’re installing a septic system for a new building, upgrading your existing installations or even completely replacing your septic tank and drainfield, Vallex Excavation is with you from planning to completion;

Several steps are necessary to ensure the proper functioning of your sanitary system. Call us to plan your project or to determine the best system for your land and needs.

There are many factors to consider when choosing your sanitary system. The size of your lot, the water table, the number of rooms in the building, the presence of a well, municipal regulations and the permeability of the soil will all determine the size of your drainfield and whether you need one or more septic tanks.

There is no expiration date on a septic tank or drainfield. Your system will perform
adequately on average between 20 and 35 years. In general, when the septic field is clogged, saturated or plugged, bad odors will invade your property and your home. You may experience water backups in your toilets, showers and sinks. Don’t wait, and get in touch with an expert as soon as possible.

Depending on the characteristics of your site, and if space is too limited, it may be possible to install a septic tank without a drainfield. Here are the different types of sanitary systems :

  1. The primary septic system with a standard tank and drain field is ideal for large lots with lots of space and is often the least expensive solution;
  2. An advanced secondary septic system with two tanks makes it possible to install a smaller leaching bed.
  3. The tierce septic system with two tanks and a UV lamp offers the option of not installing a leaching bed. This system is, however, the most expensive.

Yes, if your land is made up of several trees, you’ll need to have a minimum margin of 2 metres without trees around the drainfield. It is also forbidden to install a leaching bed less than 5 metres from a building, 30 metres from a well, 15 metres from a sealed well or if there has already been a leaching bed in the same location in the past..
