Renewal of Waste Water Collection and Treatment
Renewal and upgrade of existing wastewater treatment infrastructure to improve energy performance, effluent quality and resource recovery.
Substantial Contribution to Climate Change Mitigation
The renewal must achieve at least a 20% reduction in net energy consumption per population equivalent per year compared to the pre-renewal baseline. This can be achieved through upgrading aeration systems, installing high-efficiency pumps and motors, improving sludge digestion to increase biogas yield, or deploying heat recovery from effluent.
Where the renewal includes addition of anaerobic digestion or upgrade of existing digestion capacity, the biogas produced must be captured and used for energy generation or upgraded to biomethane. Methane leakage from digestion and biogas systems must be below 1% of total biogas produced.
Substantial Contribution to Climate Change Adaptation
A CRVA under Appendix A must be carried out for the renewed facility, addressing increased storm frequency, flood risk, changes in influent characteristics due to drought, and thermal impacts on biological treatment.
DNSH: Climate Change Adaptation
The renewed infrastructure must incorporate resilience features against identified climate risks. Critical equipment must be protected against flood levels projected under RCP 8.5 scenarios for the facility's remaining operational lifetime.
DNSH: Water and Marine Resources
The renewed facility must maintain or improve compliance with the Urban Waste Water Treatment Directive. Effluent quality must not deteriorate during or after the renewal process. Temporary bypass arrangements must meet minimum treatment standards.
DNSH: Circular Economy
Materials from decommissioned equipment and structures must be recycled or recovered to the maximum extent. At least 70% of non-hazardous construction waste must be prepared for re-use or recycling. The renewed facility should incorporate design features that facilitate future upgrades and resource recovery.
DNSH: Pollution Prevention and Control
Construction activities must be managed to prevent pollutant release to the receiving environment. Noise and odour controls must be maintained during renewal works. Any hazardous materials encountered during demolition must be handled in accordance with EU hazardous waste regulations.
