As long as the owner has not complied with the obligations set out in articles L. 1331-1 to L. 1331-7-1, he is required to pay a sum at least equivalent to the fee he would have paid to the public sewerage service if his building had been connected to the network or equipped with a statutory independent sewerage system, and which may be increased by a proportion set by the municipal council or the council of the Lyon metropolitan area, up to a limit of 400%.
This sum is not recovered if the connection obligations set out in the same articles L. 1331-1 to L. 1331-7-1 are met within a period of twelve months from the date on which notification of the penalty is sent.
The conditions under which the sums mentioned in the first paragraph are established, recovered and allocated are determined by decree in the Conseil d’Etat.
