About Us

Grant Tech promotes wastewater excellence by providing operational support to wastewater treatment facilities across North America. We make facilities perform in ways not imagined when they were constructed. We specialize in nutrient removal (ammonia, nitrogen, and phosphorus) and O&M cost savings.

We provide unique “wastewater excellence” training and conceptual wastewater design services.

Our consulting office is in a former shipping captain’s home in historic New London, Connecticut, the city that turncoat Benedict Arnold set afire in 1781.
