Effective wastewater management is key to protecting health, the environment, and water resources. At NSI, we specialize in advanced solutions for collecting, treating, and disposing of wastewater, transforming it into a valuable resource for a cleaner, healthier world.

Your challenges

Outdated or overloaded wastewater infrastructure

Aging systems can't keep up with population growth or extreme weather, leading to frequent breakdowns and inefficiencies.

High maintenance costs and limited monitoring

Without smart monitoring tools, identifying issues is reactive and expensive, increasing operational costs and service delays.

Strict environmental regulations

New laws demand advanced treatment and higher water quality, which many systems aren't equipped to meet.

Community concerns over public health and water quality

To maintain public trust and protect both health and the environment, wastewater systems must reliably remove harmful pollutants such as PFAS, micropollutants, and nitrogen—substances that citizens rightly expect to be managed with the highest standards.

How can NSI meet your needs?

At Saur, we understand the daily challenges facing municipalities. Our municipal wastewater solutions are built to reduce your operational burden, enhance system performance, ensure regulatory compliance, and move toward a more sustainable future. We combine decades of experience with smart technologies and a commitment to public health and environmental protection.
