As a contributor to the research on Building Regulations Part G, I align with Waterwise’s recommendations for improving water efficiency. The current method of calculating individual water consumption levels is flawed and statistically unsound, as my work with Albion Water, implementing dual-feed metered systems, has shown. This supports the argument, backed notably by Thames Water, against using this criterion for benchmarking.
I advocate for Waterwise’s proposal that all new-build properties should include rainwater harvesting or greywater reuse systems on a centralized, development-wide scale. Retrofitting existing properties with rainwater harvesting systems could significantly cut potable water use and mitigate flooding from heavy rains.
In my capacity, collaborating with UK Water Companies, we’ve installed advanced rainwater recycling systems that outperform traditional systems in urban areas, offering high water attenuation with minimal space requirements.
However, I must counter Waterwise’s claim that Non-Appointed Water Companies (NAVs) lack incentives for promoting water-saving measures. From my experience, NAVs like Albion Water actively promote water conservation through customer education and initiatives, such as our extensive social media campaigns.
Despite their growing role in new developments, NAVs face challenges compared to larger Water Utility Companies (WUCs) but remain committed to enhancing water efficiency and environmental sustainability. Claims that NAVs hinder national water conservation goals overlook their smaller market share compared to WUCs.
In conclusion, NAVs contribute innovatively to water management, and any regulatory review should recognize their efforts and address their unique challenges in achieving sustainable water use across the UK.
