Reducing waste, emissions, and pollution through our proven technologies and dedication to
preserving the planet
Seven Seas Water Group is a dedicated supporter of the United Nation’s 17 Sustainable Development Goals (SDGs). We recognize that our ability to deliver clean water and treat wastewater has a direct impact on the environment, people, and planet. Everything we do revolves around our vision of making a positive impact in water-stressed regions and helping build and maintain critical water infrastructure in the U.S. and around the world.

In recent years, our public-private partnership (P3) and build-own-operate-transfer models have expanded rapidly, giving more regions access to the updated, sustainable water infrastructure they need, even in the absence of investment capital.

We continue to build infrastructure sustainably, earning a Silver Earthquake Rating and the first-ever USRC Gold Wind Rating for our resilient water facility in the Caribbean. Our decentralized strategies maximize water resources and decouple growth from environmental harm. Our clients know our commitment to sustainability is not a slogan but a business model, and we look forward to growing with them in the future.

When it comes to water management, the United States has set a 2050 Net Zero goal. According to the U.S. Environmental Protection Agency, Net Zero focuses on water conservation, lower energy use, diminishing solid waste, saving money, and increasing sustainability and resilience.

Seven Seas Water Group has followed suit, taking new steps toward the company’s own 2050 Net Zero goal. Learn more about our efforts here.

What Is the GRESB Assessment?

In 2023, Seven Seas Water Group underwent its third GRESB Infrastructure Asset Assessment. This global evaluation provides objective scoring and peer benchmarking of ESG performance. Seven Seas attained GRESB’s top five-star rating with a score of 100/100, ranking 1st among 6 peers.

We believe our WaaS® model and the strength of Morgan Stanley backing are an unbeatable combination when it comes to delivering updated water infrastructure, and our GRESB rating highlights the ESG value of all of our projects.

Latest Sustainability Project

Lima, St. Thomas
Many phases of the Seven Seas’ water and wastewater treatment operations are benefiting from efficiencies. At our Lima, St. Thomas plant, 20 solar panels have been installed, with an estimated 71% offset of annual usage. Our impact is estimated as 13,843 kWh annually avoided from the grid, the equivalent of 9.8 metric tons of carbon dioxide.

Our Water and Wastewater Solutions Make a Positive Environmental Impact

Energy-Efficient Plant Designs

The energy recovery systems in Seven Seas desalination plants deliver up to a 60% energy savings for a significantly smaller carbon footprint compared to conventional structures. In 2021, these systems saved 62.5 MWh of energy and prevented the release of 32 tons of carbon dioxide into the atmosphere.

Reducing Reliance on Fossil Fuels

Seven Seas is actively pursuing carbon footprint reduction and phasing in alternative energy sources — including solar energy where viable — in all of our operations. In Trinidad, we are installing more than 2,000 watts of solar lighting, and regularly conduct energy audits on selected sites as we work toward our 2050 carbon net-zero goal companywide. In 2023, 5 MWh of the energy we use is sourced from renewable energy, which is a 400% increase from the previous year — the equivalent of 3.5 metric tons of CO2 avoided.

Because of Seven Seas operations, many service areas no longer need to rely on energy-inefficient water tanker trucks, eliminating up to 140,000 tons of carbon dioxide equivalent pollution each year.

Sustainable Production

The shipping industry is responsible for almost 3% of the world’s total CO2 emissions. We use powerful logistics strategies to consolidate shipments and reduce our carbon footprint and landfill waste. Seven Seas actively participates and promotes waste recycling and reuse wherever opportunities exist.


Protecting Marine Life in Trinidad

In the island nation of Trinidad and Tobago, a 6.7 MGD (25,379m3/d) Seven Seas desalination plant serves the borough of Point Fortin. Seven Seas initiated an environmental management program to monitor effluent quality, including benthic fauna surveys to monitor the effect of brine outfall on the marine ecosystem. Seven Seas subsequently made adjustments to the plant to protect sensitive marine life.

According to a Harvard study, the project produces fresh water of exceptional quality and has outperformed industry norms in monitoring its effluent. The researchers concluded, “This project creates a clear net positive impact on the community, achieving water supply for 29,000 people.”
