rainwater harvesting systems in Peterborough will also enhance the city’s Environment Capital aspiration. I also fail to understand why AW have never been brought to the attention of the Competition Commission. Are the rules different for them? told me that it is FREE to have one installed and you can change your mind and revert back within 2 years. That give you chance to see if you are benefitting or not. I asked this approx 3 months ago. The free installation isn’t a new thing. They offer it all the time so it’s not a favour.
