SAN DIEGO (KGTV) -- The city of San Diego says that for the fourth year in a row, the number of water main breaks in the city has gone down.

"It's a huge project throughout the city," Arian Collins with the City of San Diego said.

Since 2013, the city has taken around 180 miles of cast iron water pipes and replaced them with longer-lasting PVC. Last year, the city had only 33 water main breaks, compared to 131 at its peak in 2010.

"Some of our cast iron water mains are 100 years old, so they've gone way past their life expectancy," Collins said.

The city hopes to replace the remaining 55 miles of cast iron with PVC pipes by 2025.

During the last decade, the city has paid more than $2.3 million in damages from claims and lawsuits caused by broken water mains.
