An ancient city, Acco has relied on the gulf that it has neighbored since biblical times. Now that gulf is in great danger of turning into a sewage pool due to a pipeline built to carry sewage from regional factories directly to the sea. Over 10,000 Acco residents signed a petition protesting the operation of the ALA Pipeline and the sewage spilled into the Gulf of Acco as part of Zalul’s campaign. This campaign has received enormous support from both the residents and local leaders, notably the mayor, of this UNESCO World Heritage Site.
