Raw Water Intake
The raw water intake is located 100 feet below the surface of the Niagara River. The tunnel is seven feet in diameter and over 6,000 feet long. The water is gravity-fed through the tunnel. A pretreatment process has been added to the tunnel to prevent the growth of zebra mussels and aid in oxidation of organics that cause taste and odor problems.
Upon entering the water plant, the water passes through a screening process that removes debris, small fish and heavy algae growth to prevent damage to plant operating equipment. From here, a combination of four low-pressure pumps lifts the raw water to the main treatment building.
- Aluminum Sulfate - A coagulant that causes small particles to stick together
- Lime - Added to raise the pH of the water to prevent corrosiveness
- Limestone - Added to provide more weight to the coagulated particles so they settle more easily
- Fluoride - Added to help prevent dental cavitiess in young children
- Potassium Permanganate - Added to help remove taste and odors and prevent zebra mussel infestation
- Chlorine - Disinfects harmful bacteria
- Carbon - Added to improve taste and reduce odor in water
