Safe Water Programme – Nigeria – VPA 16

Audit Analysis

The Safe Water Programme in Nigeria has a VVB-confirmed investment additionality test and a named verification body, but is undermined by a severe FNRB contradiction (82.3 national default vs. 0.96 local field measurement across two verification reports), an unaddressed leakage justification, the absence of any buffer pool or permanence mechanism, and 22 outstanding corrective actions. The project's claim safety is materially weakened by the FNRB discrepancy, which could represent an order-of-magnitude over-crediting risk if the lower local-field value is the correct one.

Project Description

Red Flags

• ⚠FNRB value contradicts between the 2023 verification report (0.96, local field measurement) and the 2024 verification report (82.3, national default) — an approximately 86-fold difference that is not explained in the extracted record and could indicate a unit error or a material change in the baseline emission factor.
• ⚠Leakage deduction is 0% and the verification report (2024-07-25) records the justification as 'not addressed,' while the monitoring report (2024-07-23) claims it is 'deemed negligible' — the higher-priority VVB document does not support the negligible claim.
• ⚠No buffer pool percentage, no permanence claim period, and no reversal-event record are found in any available document, leaving the project's permanence and reversal risk entirely unquantified.
• ⚠22 corrective actions remain open, including requirements to fix baseline parameter references (Kenya vs. Nigeria), correct a Cb parameter value, justify sampling design, and provide evidence for treatment capacity values — indicating the monitoring and verification chain has not yet been fully closed.
