Miami Beach Public Works employees battled wind and rain from Tropical Storm Isaac to patch the last of four broken water mains and restored water service to Belle Isle at roughly 2:50 p.m.
The final fix was made in an 8-inch pipe under Venetian Way just east of the bridge to Rivo Alto Isle.
Miami Beach is advising Belle Isle resident to boil water as a precaution until the water can be tested to determine it is safe. That is likely to take two days.
The same is true for residents of Sunset Harbour and Alton Road and West Avenue who received a similar advisory on Saturday.
The fix in the Belle Isle main marked the end of a 36-hour period when four city water lines failed – two 20-inch mains in Sunset Harbour, a smaller line on Rivo Alto and the Belle Isle water line.
