Aqualia wins 26-year Peru wastewater PPP in Cajamarca

Aqualia secured a major public-private partnership to design, finance, build, operate and maintain the Cajamarca Wastewater Treatment Plant in Peru. The project is expected to improve sanitation for more than 365,000 residents while expanding the company’s Peru portfolio to nearly €1 billion.

Why it matters: - The Cajamarca project will modernize wastewater service for more than 365,000 residents. - The new plant is designed to reduce untreated discharges into the Mashcón and Cajamarquino rivers. - The 26-year concession adds to Aqualia’s international pipeline and deepens its position in Peru’s water infrastructure market.

What happened: - Aqualia won the contract to design, finance, build, operate and maintain the Cajamarca Wastewater Treatment Plant in Peru. - Perú’s investment promotion agency, PROINVERSIÓN, led the public-private partnership. - The award covers a 26-year concession. - The announcement was made July 29, 2026.

The details: - The plant will handle an average flow of about 592 liters per second. - The project includes a wastewater collection and conveyance system. - The new infrastructure is intended to improve public health, protect local waterways and raise quality of life in Cajamarca. - Aqualia said the award lifts its Peru project portfolio to nearly €1 billion. - The company also cited the 2025 award of the Chincha Sanitation Project as part of that expansion. - During the award ceremony, PROINVERSIÓN Executive President Luis Del Carpio stressed continued investment in public infrastructure through PPPs. - Government officials, IDB representatives and leaders from Peru’s Ministry of Housing, Construction and Sanitation attended the ceremony.

Between the lines: - The project signals continued confidence in Aqualia’s technical, financial and operational capacity on complex water projects. - The award also reinforces a broader push in Peru to use PPPs to close infrastructure gaps. - Aqualia is using the Peru win to bolster its global sustainable water platform, while MDS Aqualia points to the same expertise in Texas. - MDS Aqualia manages water and wastewater utilities for more than 450,000 residents in Texas and says it has more than 250 professionals.

What's next: - Aqualia will move into the design, financing and construction phases before the plant begins long-term operations. - The Cajamarca facility is expected to become a key piece of regional sanitation infrastructure once complete. - Aqualia and MDS Aqualia are likely to continue pursuing utility and wastewater work in fast-growing markets.

The bottom line: - Aqualia just locked in a long-duration Peru deal that combines public-health impact, environmental cleanup and a larger foothold in Latin America.
