Air Selangor is a large water distribution company owned by the Malaysian state of Selangor. The public utility serves a population of 8.4 million residents and manages over 6200 kilometers of trunk mains, ranging from 300mm up to 2200mm, with much of the pipelines located in remote areas of the state.

Evansville is located on the north bank of the Ohio River in southwest Indiana. The City’s sewer system, parts of which are more than 100 years old, serves a population of 163,000, with combined sewers making up almost 40 percent of the total sewer area.

In 2002, the EPA entered into a federal consent decree with MSD, mandating the elimination of sanitary sewer overflows and significant mitigation of combined sewer overflows into receiving waterways. Engineers estimated the cost to mitigate the sewer overflows at $3.1 billion, an unacceptable capital expense to pass along to MSD’s customers.

Predictive monitoring and automated control optimized combined sewer operations, reducing overflow volumes and deferring major capital infrastructure investment.
