IUFMP records commissioning on 29 May 2020; the World Bank's 2023 implementation report confirms completed rehabilitation; its 2025 review records the dam-maintenance assignment as pending

Project sources

Eleyele's rehabilitation joined the dam, intake, scour outlet and downstream channel. IUFMP records commissioning in May 2020; the World Bank's February 2025 completion review identifies an unresolved dam-maintenance assignment.

Project anatomy

Contract scope and delivery roles

Client / authority
Oyo State Government through the Ibadan Urban Flood Management Project
Delivery parties
CGC-CHWE JV: rehabilitation contractor named by IUFMP in its 2020 completed-work account, Tractebel Engineering S.A., with SGI Consulting: design and supervision named in the same account
Contract route
IUFMP's 2020 account identifies the works contractor and design/supervision team. The construction award method, operative signed terms, certified quantities and final account were not established from that account. World Bank P130840 is the parent programme identifier, not an Eleyele contract value.
Execution window
The assessment is dated November 2016 and was disclosed in January 2017. IUFMP records commissioning on 29 May 2020 and a planned one-year defects period. Programme closure was 28 June 2024; the completion review is dated 28 February 2025.
Works package
Rehabilitation of the earth embankment, ogee weir, spillway and downstream river channel; intake-tower hydro-mechanical works; scour-tunnel and valve-chamber work; replacement of 600 mm scour and 450 mm raw-water pipes; access and monitoring installations, as described by IUFMP in 2020.
Marine interfaces
The dam's water-supply line shares the scour-tunnel route. The outlet and spillway routes converge downstream, so maintenance responsibilities cross the intake, dam and receiving-channel interfaces.
Commercial evidence boundary
The Bank's 2025 review states that the May 2024 asset-management plan had not entered formal use by programme closure and specifically leaves Eleyele maintenance responsibility pending. The operator's budget and waterworks/channel arrangements must cover the shared outlet and supply-line access as well as the receiving channel.

Evidence gap

What remains unverified

Outstanding evidence

  • Post-February 2025 maintenance assignment and funded asset-management arrangements
  • Final as-built routing and current approved reservoir/dam-safety operating envelope
  • Outlet, raw-water supply and monitoring maintenance, defects closeout and emergency-plan exercise records
