Our previous home fed by private well ,over the years we lived with occasional low flow and failure due to leaks and lack of rain. It was  certainly a shock  to system the first time all water ceased flowing and we had to sort problem ourselves. Pity that all disagreeing with your proposals cannot experience same ,attitudes would certainly change. I fitted a U/V system due to cattle using well field and curious that your proposals made no mention of methods used to purify river and future lake water. Middle of last year water tasted different for short period ,similar taste to water  once tasted in Birmingham , What do you add  to water as additional protection??
