As an example, for an outlay of $100,000 per year per site (excluding initial monitoring system installation) an EnviroSuite solution across two wastewater treatment plants produced a $700,000 return in one year through improved odor management, reduced plant operating costs, efficient complaints resolution, and avoided degradation to asset health. This did not include any of the intangible benefits of improved community relations, for example.
