The new eight-inch water line on Canary Street is in service, Mayor Margaret Wuerstle announced Thursday.
The line, paid for with federal grant money, boosts the water flow in the 600 blocks of Canary and Swan streets.
Also, the tops of all fire hydrants have been color-coded to indicate water main size. Orange, green and blue caps indicate flows near or exceeding 1,000 gallons per minute.
Three hydrants were installed this summer on Seel and West Fifth streets to boost fire-fighting flows to more than 1,000 gallons per minute.
The Newton Street drainage project is completed, but the contractor, S. St. George Enterprises, will finish the landscaping within the next few weeks.
The drainage project in West Green and Dove streets and Wilson and Pennsylvania avenues is about half-finished. The project includes 42 new storm water receivers and four new ditch inlets.
A storm inlet that runs into the sanitary sewer will be eliminated by the project, the mayor said.
