Hi Charles

I've done this type of work at Anglian Water for a number of years now and without knowing your project the biggest blocker to innovation in the UK is payback if that is your driver. Water Regs are pretty strict as well so make sure your in constant contact with the local water company especially for grey water systems in domestic properties. AW are very hot on compliance for this. All needs to be WRc approved etc....

After all the normal water efficient devices best to concentrate on extensive monitoring- look at the Cello V6 which can provide live alerts and data via online presentment like Watercore. Pressure management on rising main and flow control on all outlets. Rainwater harvesting for retail only and check the local water company doesn't charge return for this if used for domestic purposes. I've done many wastewater recycling projects but only for our key accounts as you really need substantial amounts of process water for this to be viable
