Water Companies are bleating about households using 'too much water during lockdown'. But how come: we had months of heavy rain with flooding, so badly that some will never return to their houses and some crops won't be sown this year. Also, is there 1 water system for office blocks, shops etc. and a separate system for private dwellings. Where's the office system being stored if that's the case ..........
25% of water if lost though old pipework - don't know if that's daily, weekly, monthly [need to read the Guardian again]. I saw a man listening to pipework outside our property a few years ago

........ with a ? copper pipe ?

I remember the hot Summers of 1975/6 when reservoirs ran empty. Doesn't seem like much has altered other than more properties being built, access to laundry machines and dishwashers, plus en-suite bathrooms ..........
