Hi there,I have two cisterna's on my property,one is filled via rainwater and the other probably from delivery I would guess,the land and I'm guessing the cisterna's haven't been used for at least 5 years so how safe is the water to use?would it be better to pump them out,clean them and start again?or could I drop some chemicals in to make the water safe?? Just for washing etc obviously not drinking?
I'm in the UK untill March but will be looking to getting a shower up n running whilst there!!
Cheers Kev
