Besides the bladder which holds in practice about 100l not the 120 quoted we have an aluminium tank divided into two 50l's under the front of the vee berth, the three tanks are hooked up to an electric pump and water can be drawn from or pumped to or filled by mains pressure.
Gives us 200l (52gals) which with judicious use can last 2 weeks and more if a fresh supply is found and the filters take care of it if it is not perfect in taste or purity (not salt).
water system
Re: water system
We had 2 150litre bladders ..one each side for water but converted one side to grey water storage as we were going to go to dam which required total retention of all waste.Now thinking about it...if I had 2 bladders in the galley seat,one for the water and the other for grey water...as one goes down and the other fills....perfect!!!
