I am talking about "mains drainage": sewage and sewage.
I think I am not sure that there will be a big gain in the sense that we already have to separate many things from the source (cf. water laws, SRU and different regulatory obligations defined by the DRIRE .. .).
For several years now there has been an obligation to separate rainwater from wastewater. In time everything was sent to the main collector.
Likewise, classified installations (ICPE) must meet a certain number of standards which are controlled by the DRIRE. Many agro installations, for example, have their own wastewater treatment plant and therefore do not discharge anything into the "public" network. Sometimes it is even the reverse that occurs. In small towns and villages, the industrial WWTP is generally oversized to be able to accommodate the US of local residents.
In addition, restaurants for example must have grease traps so as not to reject grease in the sewers. Hospitals must control their effluents and separate / treat the most dangerous ....
In fact, there is a big amalgamation because we always speak of "everything to the sewer" whereas it has been a long time since this is no longer the case. Today we are talking about a wastewater collector and technically there is a huge difference.
Otherwise, for the lead, I checked with a friend who is in real estate. He told me that the law has existed since 1989 but that the diagnosis does not relate to "the presence or absence of lead" but on what quantity is released.
Concretely, the pipes will have to be changed from 2013 (European regulations require) because the thresholds will be too low to set up a treatment system.
The current thresholds are 25µg / liter. It is still worrying when you know that lead accumulates in tissues.
