If I am going to filter this river's water a big settling tank would be essential, there is a massive amount of suspended silt most of the time, it is never very clear except in the height of summer, in winter it is more like liquid chocolate. I suppose one route might be to put the settling system and first prefilter ashore and use a realy big container like an IBC for the settling tank Practical for me as I have a half size container for storage next to the boat (with power) A flood proof system ashore seems to make sense. You’ve fitted a Hiab haven’t you? So maybe a lift on lift off system? In the end I turned down the hiab, tempting though it was (being free ) as it would increase my airdraft several inches above what I had managed to reduce it to after buying an extra 5 tons of steel block ballast
Much as I would have loved to have it, it was an old fashioned one that was still nearly 6 foot high when folded right down
Where I can go on the rivers and canals is very limited because of my airdraft and just those few inches lets me get under Heck bridge and opens up a lot more of the system

Ah yes very sensible plus old hiabs can be a liability.

I've not been that interested before as there are various bulk water supplies on the Thames however these have recently been changed and the new elfin safety taps take about 5 times as long to fill so my bulk tanks which usually take half an hour would now take over 2 hours which is too long to be sitting blocking a water point. So filtration it is. Always fancied it and now motivated to actually do something. Don’t forget the photos.

Well anyway this is the settling tank... It's big enough to get a body in so my heart was racing and I did wonder if it was a safe. But no, just a slightly but not too rusty settling tank with an anode bolted to the lid. Which could do with a clean up. There is an associated but not immediately adjacent raw water inlet. The tank is suspended and not part of the shell plating. None of the water tanks on this boat use the shell plating, only the diesel tanks do this.

I guess there is the chance of water in cabin when boat moving about so belt and braces plus extra belts plus extra braces. Anyway it's mainly scale in there. Steel is pretty good. At the starboard end there is an stainless offtake for a garden hose I guess you put a float on it to pickup just below top of water level, and a downwards pipe for sucking out the sludge. These are hosed externally and hoses capped off. Platform and power supply for sludge pump but curiously no skin fitting so I guess it's a bucket job. Dulcinea has always had an unresolved list to starboard when "all tanks full" but this one I have never filled. It will resolve the problem as it is to the port side and actually quite large... Reason I did not investigate before is because the boat was originally meant to have pressure fed stern tube lubricators but these are not connected. I had assumed this tank was for the oil for those but would make much more sense to have that in engine room not in living space !! Anyway it is a large sedimentation tank for a filtration plant, and a nice one. Mainly scale in there no serious rust. Picture shows the outlet pipe onto which a normal garden hose fits so I assume a float system and the other one is right down the bottom for sludge removal. Other end of lid there is a stainless inlet spigot and a hose which goes from that to a deck vent and option to lead it to the below water inlet via a sea cock.

This is all terribly fascinating but if it were me I'd fix the engine before getting too concerned about long-range expedition water supplies.

Just needs fiddling with as you saw plus I need a bigger hattery for it. Anyway this is for short range water supplies. Long range ie anywhere down River would require a desalinator I believe. That's a different thing altogether. ETA pair of BMC 1.5s. port engine as new starboard engine slightl starting problem probably to do with heater plugs. Once running no problems. I don't want to get someone in to break it for me.

I suspect andrew will fix the problem when it becomes a problem... Some of us are just that way.

Chlorine is a great sanitiser, that is why all water companies use it to kill any bugs which may get in to the supply. UV lamps gradually become less effective over time, they are not suitable for domestic use, they are used in industry, along with testing of the supply.

I am definitely interested in chlorine and chlorine filters.
I knew about adding it but didn't realise you can also dechlorinate the water.
That's really handy.

This vlogger had a system installed (cost well over £1000) to filter canal water, and he still uses it now, but for river water you wouldnt need quite so many filters.
If you had lots of spare power you could run filtering pumps several hours a day, but otherwise I think it would get a bit expensive to create the extra power needed.
