Renovating a non-collective sanitation system is a regulated project

Renovating a non-collective sanitation system is a regulated project. Here are the mistakes to avoid and the solutions :

❌	✅
o Not carrying out a hydrogeological study.	o The hydrogeological study will determine the type of work to be carried out depending on the nature of the soil and the space available
o Installing a system that is inappropriate for the type of soil or the capacity of the home.	o Have the soil study validated by the SPANC before starting the work.
o Using a works company that is not qualified and/or insured for this type of work.	o Select a competent works company and ask for its ten-year certificate.
o Neglecting administrative procedures that could delay or compromise authorisation of the work.	o Ensure that the project manager has the work inspected during and at the end of the project, in order to obtain a certificate of compliance from the SPANC.
