ISTP2 — Al Wathba 2 & Al Ain (Allahamah) Independent Sewage Treatment Plants

United Arab EmiratesWastewater Infrastructure, Water InfrastructureReviewed 11 September 2026

Two plants under one BOOT concession, commissioned January 2012 — UAE's pioneering ISTP PPP structure. Original sponsoring structure named as Abu Dhabi Water & Electricity Authority (ADWEA) and Abu Dhabi Sewerage Services Company (ADDSC), both pre-EWEC-era entities. UNRESOLVED (Founder Review FR-2): whether ADWEA/ADDSC's functions for this specific concession now sit within EWEC, a successor entity, or a legacy entity was not resolvable with confidence in the research pass. Grantor/Procuring Authority relationship deliberately left blank rather than guessed — see Future Project Deepening.
