CLEAN ENERGY. POWERING WATERLINE.
In 2025, Waterline expanded its commitment to responsible infrastructure with the installation of a ground-mounted solar array at our corporate headquarters in Seabrook, NH. The system includes 178 solar panels and is designed to produce approximately 120,000 kWh of clean, renewable energy annually, helping power our daily operations while reducing our environmental impact. Through the live monitoring dashboard above, you can see real-time energy production and system performance, providing a transparent look at how solar energy is contributing to our facility each day.
