I do a lot of outdoorsy things and drink from questionable water sources. I use a gravity filter on a bag to remove lumps and then pump it through a katadyn pump with a ceramic and charcoal filter, that filters down to 0.1 micron and the company states that that it will not filter single virus’s out only clumps of virus, so I boil it. But I would be drinking from sources similar to the actual cut, that you wouldn’t put in your water tank. I agree with the previous comment that reverse osmosis is the best solution on a NB or vehicle if you want to be sure that the water is clean, but it can be pricey. Alternatively use a cheaper filter and a charcoal filter (to remove flavour), boil it and make tea.

Birmingham water should be really clean as it’s been filtered through lots of kidneys.

2 tins of chopped toms; 1/2 finely chopped onion; 1 ltr Tom juice; 1 tin mixed beans in water; a good squirt of garlic toothpaste; an even better squirt of tomato purée; 1 veg bouillon cube; good pinch dried basil; good pinch dried oregano; 1/2 ltr water; couple of leaves of (relatively) finely chopped cabbage; couple of rashers of cooked unsmoked bacon - chopped (unless meats not your thing) and pasta, I like macaroni tubes, it makes it a nice meal. all in a pan, save for the pasta, bring to the boil, allow to reduce, add the pasta, simmer till soft (or al dente if your posh). Correct seasoning and consistency (potato powder works well). Serve with lumps of bread. Nice and easy and filling
