Sadly they can't stop what happens with issues like HS2
which is ploughing it's way through 5 SSII s etc..
We were Members of our local one for a few years: we have been Members of the Wildlife and Wetlands based in Slimbridge. We used to count bats for the local Trust and we have the hedgehogs.
Someone on Jeremy Vine yesterday was saying that the UK will be 'out of water' by a date which I can't remember and there were ideas on how to cut back on usage. Useful then if the Water Companies plugged all the leaks and if the UK stopped building houses without water collection tanks to use for grey water which is apparently, a legal requirement from the EU but has rarely been put into practice. The 1 'green' estate of over 1,000 properties in our area had problems because the pumps for the grey water tanks failed but no one would take responsibility for maintenance
you really couldn't write it
. Builders had moved on; management company went bust; LA couldn't afford to take the maintenance on. Pumps lasted 7 years
so good idea at the time.
We try to save water when we are able to. We also have holding barrels/tanks in the garden rather than using tap water. Would love to be able to retro fit a water system for grey water but there isn't enough room here. We plant trees .........
