ECUA is still working to replace over 15,000 blue cans in North Escambia. The cans were used by Allied Waste, a company that ECUA took over in January 2009. ECUA customers are asked to leave their blue cans at the curb after this week’s pick up as crews will be working each day to replace them. Cans that already have the ECUA logo are not included. ECUA spokesperson Nathalie Bowers said the old cans are at least 12 years old and will be recycled.
