This is nothing but a Conservative plan to reduce services. I agree some households do not need a weekly refuse service, but some do. This service is supplied to everyone regardless of need. Crowded households, those in flats and those with young children/babies will suffer by having to keep rubbish in and around their homes for longer. Increased vermin and disease.
What we need to develop is daily collections of refuse from community refuse storage areas. Used by those who need it and not used by those who do not. Doorstep collections of rubbish just causes pavement cluttered with various coloured wheelie bins, unless of course you have a huge garden and a nice long drive!
