recovery of rainwater
- Question
- Hello,
My three year old child has CF and has already been contaminated by the P. aeruginosa. In my job, my accommodation is allocated. My accommodation is new (not yet delivered, but on the way). But I am a little concerned: there is a huge rainwater tank which feeds an outside faucet and toilet. (No possibility to modify the installation). Should I deny this housing or do you think that the risk of contamination is low? (Subject not to have extended aerosol in the toilet, of course). Thank you for the answer and for your answers in general!

- Hello,
You have well evaluated a potential risk of contamination with Pseudomonas aeruginosa in a situation of stagnant water in a rainwater tank, which is a potential reservoir for Pseudomonas aeruginosa, indeed with aerosol arriving in the restroom. If you have the opportunity to have another accommodation, it seems better.
If it is very complicated for you to request this change, here are some options to limit the risks:
You should lower the toilet lid before flushing the water, remaining vigilant because your child is small and water is fascinating at that age!
Ventilate the room regularly. Clean the tank: «It is not possible to propose a given frequency. The cleaning is used to remove sludge that eventually accumulates in the bottom. It can generate fermentation and odors. The speed at which the sludge accumulates depends on the air pollution of the place with respect to dust, the nature of the roof, the quality of the installation upstream of the storage tank».
Limit the spread of germs and algae in the tank with Micropur fort ® (chlorine and silver ions) every 6 months: you can contact them for a user manual and a quote.
The single-chlorination of the tank appears to be complicated to manage for a chlorine concentration stable and efficient. Carry out bacteriological examinations of the water tank.
Reminder: Pseudomonas aeruginosa is present naturally in the environment and the risk of contamination is always possible and even if the hygiene conditions are met.
Sincerely
Marythé Kerbrat
