AWWA Releases Water Main Condition Assessment Manual

On June 24, the American Water Works Association (AWWA) released the first edition of its M77 Condition Assessment of Water Mains.

As infrastructure ages, utilities are increasingly challenged to maintain service levels while maintaining affordable water rates. Water main condition assessment helps utilities meet this challenge by identifying more precisely where money is best spent, leaving pipelines that have adequate integrity in place and preventing the unnecessary failure of others.
