How we do it
We take on the entire project
We focus on large water projects with private financing and long-term contracts: we structure, finance, build and operate them.
Structuring and financing
We develop the project and put together the structure that makes it viable.
- Opportunity identification and development
- Technical, legal and financial structuring
- Financial models and guarantee structures
- PPP projects and unsolicited proposals
- Equity investment and financial close
- Partnerships with strategic partners and investors
Engineering and construction
We deliver large-scale infrastructure to the group’s technical standard.
- Basic and detailed engineering
- Permitting and approvals
- Desalination, drinking water and treatment plants
- Large pipelines and pumping systems
- Commissioning
Long-term operation and management
We stay in charge of the infrastructure for the full term of the contract.
- Comprehensive operation and maintenance
- Service level compliance
- Billing and customer service
- Asset replacement and renewal
- Infrastructure handover at the end of the contract
Water & industry
Keeping water from holding operations back
Under Mexico’s new General Water Law, access to water is no longer guaranteed by a concession: for industry, water becomes a strategic variable.
30%of the country’s aquifers have no availability left for new concessions
114overexploited aquifers, three times as many as in the 1970s
15–40%less water available by 2050 in industrial regions
64%of Mexico’s territory was in drought in April 2025
Solutions to operate in the new context
At GSA, we develop the infrastructure that lets industry reduce its reliance on conventional sources and secure the water it needs.
Reuse and circularity
Treatment of industrial and municipal wastewater for reuse in processes, cooling and utilities.
Alternative sources
Desalination, exchanging first-use water for treated water, aquifer recharge and rainwater harvesting.
Efficiency and control
Water audits, metering and telemetry to cut consumption and comply with the new rules.
