What to know about plumbing in Baton Rouge
Brown water is usually manganese
Baton Rouge Water Company says its water is naturally filtered through underground sand and rock and is chlorinated at 1.4 parts per million. It also contains manganese, a natural mineral that settles in the distribution lines and can tint water brown when a fire, construction or a main break stirs it up. The company suggests running cold water for two to three minutes to clear it; if discoloration keeps coming back only inside your home, have a plumber look at your own pipes and water heater.

Where the company's pipe ends and yours begins
Baton Rouge Water Company owns the service line from the water main to the meter, while the plumbing line from the meter to the building belongs to the property owner. The company is building an inventory that classifies lines as lead, non-lead, galvanized requiring replacement or unknown, and customers can search their address online. If your line is listed as unknown, a plumber can check the material where the pipe enters your home. Source: Baton Rouge Water Company: Service and Plumbing Line Material Inventory
