Tetra Tech is providing engineering solutions to help the community of Sanibel Island, Florida, improve their water quality, helping to preserve wildlife and vegetation.

Tetra Tech is using high-end engineering solutions to improve the community’s current water treatment. We changed their two-stage biological treatment process to a four-stage process, complimented by a membrane bioreactor system. Our four-stage process will reduce the phosphorous and nitrogen levels in the water by 50 to 70 percent. By significantly improving the water quality, we are preventing algae blooms and dissolved oxygen levels in the water, which could lead to negative impacts on wildlife.
