Key Terms

2 terms

liquid chlorine disinfection system technical

"A liquid chlorine disinfection system upgrade at the Peoria Water Treatment Plant."

A liquid chlorine disinfection system stores and meters a liquid form of chlorine into water supplies to kill bacteria, viruses and other contaminants, similar to adding measured bleach to a swimming pool to keep it safe. Investors care because these systems are critical for regulatory compliance, public health and reliable service; they create recurring revenue for chemical suppliers and maintenance providers while carrying safety, liability and capital-cost implications for operators.

wastewater lagoon berm technical

"An enhancement to the Warren Levis Wastewater Lagoon Berm in Godfrey to address erosion..."

A wastewater lagoon berm is the raised earthen rim or embankment that surrounds a holding pond used to store and treat wastewater. Like the edge around a backyard pond, the berm keeps liquid contained, prevents overflows and controls runoff; for investors it signals ongoing maintenance, inspection needs and potential environmental liability or regulatory costs if it fails or requires upgrades.
