compared to other types of equipment. impacts of climate change on sanitary engineering vary based on region and the sanitation solutions employed there. in the arctic, permafrost melting has caused damage to pipes and other infrastructure. in the northeastern united states, increased precipitation has overwhelmed aging infrastructure not equipped to handle the massive volume of water from heavy precipitation. in the western united states, prolonged drought has decreased water availability. this has led some wastewater facilities to expand recycled and reclaimed water programs. climate change has also affected water distribution pipes. physical stress from climate change-related conditions such as extreme rainfall or drought increases the rate of pipe corrosion, adding to facility cost.
