Executive overview
Key findings
179 mm: rainfall in Jeddah on 24 November 2022, "the highest amount ever received in the city" (National Center of Meteorology, reported by Arab News)
46%: share of the city covered by completed or in-progress stormwater projects at end-2024; targets are 75% by 2028 and 100% by 2033
About USD 175 million per phase: KAFA stormwater tunnel phases 1–2, contractor selected in 2025, agreement unsigned as of August 2026
613.9–2,216.5 km²: national coastal area that a 1–3 m sea-level rise could submerge; Jeddah is named with Al Wajh and Jazan as the major Saudi coastal cities vulnerable to sea-level rise (NC4, citing Hereher 2020)

Buyer relevance
Who the report is for
Drainage, tunnelling and pumping contractors
Follow the Prince Fawaz, Old Zahraa and KAFA procurements that decide whether coverage moves from 46% towards 75% by 2028.
Climate risk and insurance analysts
Use the 179 mm event, the 2018 station rainfall of 86.4 mm and the national sea-level scenarios as the published basis for Jeddah flood exposure.
Water utility and desalination investors
Separate Jeddah's rainfall-independent desalinated supply from its flood and coastal exposure when assessing asset risk.
03
Decision scope
Questions answered
Is Jeddah exposed to drought?
Its primary supply is desalinated seawater, which does not depend on rainfall; the documented hazard is flash flooding, such as the 179 mm that fell on 24 November 2022.
How much of Jeddah is protected by storm drainage?
Completed or in-progress stormwater projects covered 46% of the city at end-2024, with targets of 75% by 2028 and 100% by 2033.
What drainage contracts are pending?
The KAFA tunnel (about USD 175 million per phase) awaits a signed agreement, Prince Fawaz drainage bids (about USD 60 million) close on 15 November 2026, and an Old Zahraa package (about USD 30 million) had bids submitted on 16 September 2026.
Is Jeddah vulnerable to sea-level rise?
Saudi Arabia's Fourth National Communication names Jeddah with Al Wajh and Jazan as the major vulnerable coastal cities; nationally a 1–3 m rise could submerge 613.9–2,216.5 km².
