One of the state’s largest water utility is facing significant challenges with excessive inflow and infiltration (I/I) in its gravity collection system, consisting of over 1,500 miles. Precipitation events often result in immediate flow responses within the collection network, at times up to 3 times the average daily flow ...
According to UN data, water and climate-related events have accounted for half of the human and economic damage caused by disasters over the last fifty years. Figures show that, during this period, weather, climate and water hazards accounted for 45% of recorded deaths (1.3 million people) and 74% of global economic losses.
