Rainwater for WCs: what does the law say?

[gegyx]

On Orleans it is separate. The rainwater from the roofs goes into a network which flows into the river.

Next to my house, there is a large tarmac supermarket parking lot, with multiple fuel pumps.
Under it, there is a private recovery network, passing through an oil separation decanter (like a septic tank). The water that comes out of it joins the rainwater network. As for the decanter, they passed sleeves to pass wires, in order to monitor the overflow of the retention tank (I watched the case closely). The wires have never been passed ... There is a trap door, but with dirt on it, and it has been like this for 6 years ... (Life, real ...).

As for the manholes along the streets and sidewalks, I do not know if there is prior settling or a separation network? Because with the rainwater collected, there are leached oils (cars, tar), and trash (leaves and sweeper).

When we speak of a rain network, this corresponds both to the drainage water from the roofs but also to the entire road network.
For the problem of large waste: leaves, branches, plastic bag ... it is filtered by a simple grid.
For the rest of the pollutants, oils, hydrocarbons, in short everything that may come from the leaching of the roads by rain ... I don't know.

There may be decanters on the rain network, but despite all my attempts to communicate with the cast iron plates in the street, they never answered me Generally there is not marked on the plates what is below.

However, during the repair of a counter-aisle serving as a delivery access to my workplace, I discussed with the site manager the presence of a hatch in addition to the manholes.

It turned out that it is a decanter which is now compulsory according to European directives, from what he told me. So this should gradually become generalized, during the reflexions of the roadways or rainwater networks. After all is a maintenance problem as said by gegyx. You have to watch what's going on inside from time to time.

following the 1 st question
I just reread my sanitation contract

and there find the error

6 article
ban on the discharge of spring water and heat pumps.

15 article
but if the user is totally or partially supplied with spring water other than a distribution service he should pay a lump sum or put a meter at his expense to pay the fee

25 article

groundwater and groundwater are not considered rainwater


water service contract

the interconnections between the well water pipe and the distribution service prohibited

So playing on the words I have a well so no right to reject the sewer but the rain yes;

It's a shame it rained that 60mm since August 28. So I think that by installing a tank it will often be dry.

Bonjour,

to be more clear: you will not have a tax credit on the tank if it is used for anything other than watering: which prohibits wc and washing machine

False! ...
this is precisely what I was explaining ...
if you use the tax credit, there will be the appropriate rules to respect ....
if not .. it does not mean that the rest is "prohibited" !! , you do what you want !
these orders are there to "supervise" a practice, to define a regulatory framework ..., and not to prohibit !!! ...
Spread the word ! ....

with me no subsidy no control

False! ...
given the rules for protecting the public network that they are now releasing, and the various (new) laws that are coming ... .), when they will realize how little public water is used in your home ... they will not wait to come "to see what is happening" ... !!!

In France, circuits must be separated. A non-return is tolerated.

False! ...
double-valve or non-return valve systems will no longer be tolerated .....
(since there remains a "physical" connection ....)

Used rainwater? OKAY. But never reject it in the above-mentioned sewer.
Otherwise we are a fraudster.

False! ...
it is now prohibited to reject "rainwater" to the sewer network !! ..
(OK to the rainwater network if already equipped with "separate networks" ..)
however, the rainwater that you use in the house , and you reject after use to the sewerage network is no longer rainwater but waste water !!! , just like the rest of the house ...
watch out for this frequent confusion .....

So playing on the words I have a well so no right to reject the sewer but the rain yes;

heuuu no ... what makes you say that ... ??

cordially

Good, I correct: Anti-return was tolerated until then.

Used rainwater? OKAY. But never reject it in the above-mentioned sewer.
Otherwise we are a fraudster.

(OK to the rainwater network if already equipped with "separate networks" ..)

Yes, but I didn't confuse me, since "the aforementioned sewer", concerns the one who succeeds "... to the sewer, treated by the treatment plant. ", for which, "there is a sanitation tax on the cubic meter consumed"

[little sparrow]

Re gegyx,

Yes, but I did not confuse it, since "the above-mentioned sewer" concerns the one which ends "... in the sewer, treated by the purification station.", For which, "it there is a sanitation tax on the cubic meter consumed "

uh .. 'xcuse me but, if i understand what you say ..

Used rainwater? OKAY. But never reject it in the above-mentioned sewer.

the rainwater used ... it must be rejected where then ?? ... if it is not in the "sewer treated by the STEP" ... ??

[chatelot16]

the prohibition of a connection between drinking water from the network and personal production water is completely normal: I say that my rainwater is good: it is my business, but I do not have to send it to neighbors in the event of a valve leakage valve error or mounting upside down

in the industry there are double safety valves with reduced pressure zone between the 2 which avoid any risk of mixing: but the one who wants to mix in the same circuit rainwater when there is water of the city when there is no more has a simpler solution: leave connected to the tank and fill it a little with city water in case it is empty

Re chatelot16,

there are double safety valves with reduced pressure zone between the 2 which avoid any risk of mixing:

yesss ... the "AB disconnector" .....
it is possible that it is the only physical connection system that will remain authorized ....
but more expensive, and to be checked every 6 months now by an approved pro ...

but the one who wants to mix in the same circuit the rainwater when there is it and the city water when there is no more has a simpler solution: leave connected to the tank and fill it a little with city water in case it is empty

well yes ... solution which indeed allows a total physical disconnection ... and this is the system that i installed at home ...
and that I recommend, also with another, which is simply the flexible hose system to be connected either on one inlet or on the other ....

Personally, I prefer not to send city water to my tanks, because I also drink water, and I am very demanding on the quality of raw water (in storage) too, because city water would change the physical- EDP ​​chemical ..

but given my storage capacity, I don't run the risk of being dry .., so I opted for the 1st system anyway, to "do well" and reassure who would come and check my installation ...
