"PVC pipe or plastic piping and ductile line pipe," says Josh Rabon, managing partner for Civil Engineering of Columbia. "Those are the two main types of pipes that are installed now."
"A lot of the old pipe material the galvanized, the cast iron the concrete, those aren't put in now," says Rabon. "Those are the ones that were put in so long ago."
"The PVC is probably a 50-70 year lifespan typically," says Rabon. "The ductile probably pushes a 100 year lifespan. So, the pipes in the ground now are definitely have reached the end of their lifespan, if it hasn't already passed."
Many cities around the state are replacing those old pipes with new ones. However, cities can only go so far.

For example, your city or municipality controls water lines throughout the city, but after the water meter on your property, the pipes are your responsibility.
Some water treatment facilities, like in Columbia, use chemical compounds in the water to treat potential corrosion of pipes in homes, but the the easiest solution for homeowners who are concerned about their water quality could be to use a filter.
"Even discolored water could very well be safe," says Rabon. "But if it doesn't look clean that doesn't give you much peace of mind."
