Septic tanks and sewage network

Septic tank emptying is mandatory for all citizens with this type of installation. Regulation Q-2, r.22, Section V, Article 13 stipulates that a septic tank used on a seasonal basis must be emptied once every four years and a septic tank used all year long must be emptied every two years.

Holding and watertight tanks are emptied upon request, a maximum of two times per year. Additional emptying will be invoiced to the owner at actual cost. Septic tanks and catch basins may be emptied in an emergency situation or in the event of upgrading work carried out. 

The periodic emptying of septic installations is essential to ensure the proper operation of components and avoid backflow problems and environmental contamination.  The regular emptying of a septic tank is necessary when it prevents sludge from heading to the disposal field or hinders its operation. A malfunction of the scrubber component can lead to backflow in the home or leakage into the environment.

Unwanted plants and animals

Plants and animals become unwanted by humans when they are not in the right place at the right time.

Species of plants listed below present risks. Some are toxic to humans: poison ivy, giant hogweed and ragweed. Others, like Japanese knotweed, represent a risk for local biodiversity.

You should never compost these unwanted plants. They should be placed in garbage bags and disposed of in household waste.

Giant hogweed

All parts of the giant hogweed contain chemical substances activated by light. Any contact with the sap can cause serious burns, blisters and scarring. Sensitivity to sunlight can last for several months after contact.  

Highly toxic specimens of giant hogweed have been detected within the City’s territory. You are obliged to eradicate it under the terms of a municipal by-law.

Japanese knotweed

As its name indicates, Japanese knotweed is from Asia. It was introduced in Quebec as an ornamental plant and is often used as a hedge. Once planted, it is almost impossible eradicate.  Because the plant propagates vegetatively, a single fragment of root, stem or rhizome left in the ground will cause the plant to grow.

Poison ivy and ragweed
Poison ivy and ragweed are often mistaken. In addition to their different appearance, they do not affect people’s health the same way.  Ragweek only affects those who are allergic (about one person in six). It is generally responsible for what people refer to as “hay fever” when it releases pollen during the flowering season. Contact with the sap of poison ivy leads to inflammation: there must be physical contact with the plant for a reaction to occur.

Unwelcome animals

The presence of skunks and other unwanted animals such as raccoons, rats, moles, deer and many species of birds is not unusual within a territory such as Saint-Augustin-de-Desmaures. The patchwork of farmland, green spaces, wooded areas, flower gardens and vegetable gardens provides the animals with favourable living conditions. Sometimes citizens even feed them for their own pleasure, despite the inconveniences that may be caused to their neighbours.
