However, recent computer modeling studies indicate that coastal wastewater infrastructure, which includes sewer lines and cesspools, is likely to flood with groundwater as sea-level rises. A new study, published by University of Hawai i (UH) at Mānoa earth scientists, is the first to provide direct evidence that tidally-driven groundwater inundation of wastewater infrastructure is occurring today in urban Honolulu, Hawai i. The study shows that higher ocean water levels are leading to wastewater entering storm drains and the coastal ocean creating negative impacts to coastal water quality and ecological health.
