"Resource recovery means we should start talking less about wastewater treatment and more about production factories." Jose Vazquez, R&D area manager, technology and in- novation, FCC Aqualia THE SPEAKERS "We were told that you could reduce capital carbon or operational carbon but you can't do both – but we've shown in recent years that is nonsense." David Riley, Head of Carbon & Energy, Anglian Water "ISO 50001 is the fastest growing ISO in the world and it is the one with the most potential… in all my years working in energy, this is the most signifi cant development in energy management." John Mulholland, Independent Energy Consultant "Volatility of energy prices will continue to be very high in the years to come, and we need to be prepared for that." Mauro Lafratta, Doctoral Practitioner, Sludge & Energy Innovation, Thames Water To Take Away A good energy strategy will cover not only the need to minimise usage, but the cost of that usage, the chance to maximise opportunities for self- generation, and the right choice of partners for external energy supply. Employees must be fully engaged with energy saving eff orts rather than these being an add-on or burden to the operational business; ISO 50001 is a useful tool for continual improvement in this regard. ESOS audits are only eff ective if they are integrated into an energy management approach; water companies must take care to appoint an eff ective lead auditor, to account for all energy use in the total energy calculation, and to have the audit signed off by a board level director. Energy storage is a growing area of innovation for water companies which can help boost resilience; storage can take many forms, with fl ow batteries and supercapacitors alternatives to lithium- ion batteries Decentralised forms of water and wastewater treatment may help use less resources and aid resilience in future, although these benefi ts must be set against possible risks to public health our own forecasting model," he added. "We know our assets best and by doing the forecasting ourselves, we nd we can mix and match between di erent assets to come up with the best response." In terms of energy generation, North- umbrian generates biogas from 100% of its sewage sludge through Advanced Anaerobic Digestion processes, as well as importing a small amount of sludge – equivalent to another 2%. Together with other renewables, the utility generates 60 GWh per year, which is set against its energy usage of 400 GWh. In a later panel discussion, it was pointed out that as well as cutting their own energy use, water companies ought to encourage customers to reduce carbon emissions by using less heated water. Hot water has over 10 times the embodied carbon of cold, which could be empasised more in water e‰ ciency e orts.
