Flood Scenario Office of Water (4608T) EPA 817-R September

Flood Scenario A succession of storms brought significant and widespread heavy rains Heavy rains were the result of a number of slow- moving storms and unseasonably warm temperatures Over several weeks, heavy rains began saturating soils, filling local reservoirs, and clogging storm drains with debris Impact felt over a (insert size of impacted area) region Office of Water (4608T) EPA 817-R September

Flood Scenario (cont.) A strong storm system then brings heavy precipitation, high temperatures, humidity, and winds producing major flooding Magnitude of flooding varies, but it is a major event Officials report creeks and rivers at 8 to 12 feet above flood stage – highest levels since 1950s NWS extends flood watch over next 2 to 3 days Sandbag barriers constructed around vulnerable areas, such as drinking water and wastewater treatment plants and low lying pump stations Many people evacuate the area Office of Water (4608T) EPA 817-R September

Drinking water utilities experience significant challenges 75 percent of area is without power Utilities request generators Placement of generators is challenging due to flooding Fuel shortages for generators expected Downed trees, violent washouts rupture numerous pipes System pressure dropping Fire departments concerned that loss of water pressure jeopardizes their firefighting capabilities Utilities do not have enough field crews to fix all of the problems Office of Water (4608T) EPA 817-R September

Drinking water utilities experience significant challenges (cont.) River flooding and large amounts of debris clog water intakes A possible crude oil spill into a major drinking water source reported Utilities receive growing numbers of consumer complaints regarding cloudy, poor-tasting drinking water Utility representatives admit that amount of time required for completing damage assessment and repair is unknown at this point Government officials, media clamoring for information and situation updates Office of Water (4608T) EPA 817-R September

Wastewater utilities also face several challenges Washouts, downed trees rupture collection and transmission lines Flooding knocks out more than 50% of area pump stations, many backup pumps fail Power loss shuts down many lift stations, causing sewage overflows and extensive combined sewer discharges into the streets Raw sewage in the streets may cause cross- contamination to due broken water mains Local industry spokespersons ask utilities to speed up repairs to continue normal discharges of industrial effluent and remain on-line Office of Water (4608T) EPA 817-R September
