Panama's Ministry of Health (Minsa) held a pre-qualification market day on July 31 for the Caimito Wastewater Treatment Plant (PTAR) in Panama Oeste province. The reference price for the new tender: $139 million.
The project covers design validation, final engineering, construction, and a full operation-and-maintenance contract. It is intended to serve more than 254,000 residents across communities including Vista Alegre, Puerto Caimito, Barrio Balboa, Barrio Colón, and Playa Leona, with the broader goal of handling population growth across the districts of Arraiján (299,079 inhabitants, per the latest census) and La Chorrera (258,221).
This is not the first lap. The plant was previously tendered under the prior administration for $111.4 million and awarded in June 2023 to the Consorcio Aguas de Puerto Caimito Oeste. The contract was subsequently returned to Minsa by the Contraloría General de la República without the required countersignature — and according to Minsa, the contractor itself indicated the project could not be executed under the conditions and price at which it had been tendered. The new reference figure of $139 million reflects that reality.
Health Minister Fernando Boyd Galindo framed the investment in public-health terms. 'Each treatment plant represents a barrier against the spread of disease and a direct investment in community well-being,' he said. María Fernanda de Mendoza, coordinator of the Programa Saneamiento de Panamá, described the July 31 session as a market-sounding exercise, not a formal bid stage: 'We are convinced that the success of these initiatives depends on participatory and transparent processes.'
Financing comes from a multilateral stack: the Inter-American Development Bank (IDB), CAF – Development Bank of Latin America and the Caribbean, and Spain's AECID. All three had representatives at the pre-qualification event alongside interested private firms. The Programa Saneamiento de Panamá, which is managing the process, claims 25 years of sanitation infrastructure work in the country. Sewage network construction in Arraiján and La Chorrera is already under way and will feed into the future plant.
Here's the thing. The $27.6 million jump from the original award to the new reference price is the real story. A contract that cleared a competitive tender, got awarded, and then came back unsigned — with the winning consortium saying the numbers didn't work — is a procurement failure, not a technicality. The Mulino administration is doing the right thing by re-running a transparent pre-qualification rather than patching the old process. But taxpayers and multilateral lenders deserve a clear accounting of what changed between $111.4 million and $139 million. Transparency in the framing is not the same as transparency in the arithmetic.
