Overview
- The Comptroller reported approximately S/200,587.72 in excess payments in Stage I – Front 2 after Sedapal applied July 2019 indices to additional works priced to February 2021, based on a review of 16 PAO valuations totaling about S/26.4 million.
- The audit also warned that the main contract’s July 2025 valuation included unexecuted quantities for civil works such as reservoirs and cisterns, and it urged Sedapal’s board chair to adopt immediate corrective measures.
- Sedapal rejected the observations, arguing its valuations follow a 2022 Dispute Board decision, court measures, and OSCE opinions, and it characterizes the cited amount as a temporary technical difference under internal review and arbitration within a 45‑day response window ending December 24, 2025.
- In a parallel regulatory clash, Sedapal initiated extrajudicial conciliation seeking more than S/1,200 million over alleged tariff underestimation, while Sunass said the claim lacks technical and economic support and cited recent financial results, an 8.4% tariff rise from January 2024, and a projected 2026 rebalance that would add roughly S/400 million a year.
- Sedapal said it has begun direct coordination with Sunass to review and harmonize technical criteria in the tariff process, as more than 1,800 markets plan a November 6 strike over wastewater‑related sanctions and fines of S/10,000 to S/30,000 under Supreme Decree 010‑2019.
