CHARLESTON, W.Va. (WSAZ) - A deeper look by WSAZ at two major water disruptions yielded new information Thursday.

Both incidents, one occurring on Patrick Street in Charleston and the other near Red House in Putnam County, involved West Virginia American Water.

WSAZ reached out asking how the incidents occurred and about any history of leaks or maintenance.

A spokeswoman said the company does not have an exact cause, but she provided more answers to WSAZ about the water lines in question.

First, there was Patrick Street in Charleston. The company says the line was 72 years old and had no no prior history of leaks.

In Putnam County, near Red House, West Virginia American said the water main and valve along state Route 62 is much younger, just 29 years old. The spokeswoman said the the valve and main had no prior history of leaks, and the valve in question passed annual inspection just last year and met all requirements.

Officials said Wednesday that the valve malfunctioned as crews attempted to restore service from a related water main break.

West Virginia American said there is no prior history of work or maintenance at either location -- Charleston or Red House. The spokeswoman said no such effort had been required due to the age and condition of its infrastructure.

She says, in all such events, the company will assess possible causes and review options for improvement, infrastructure upgrades paid for by the customer through an infrastructure surcharge on your monthly bill.

West Virginia American is currently seeking a $2 to $3 increase in that surcharge, depending upon how much water your family uses.

That surcharge increase is pending before the state Public Service Commission. If approved, the company says it will pay for for $40 million in investment. That includes more than $23 million in water main upgrades, most occurring in the Kanawha Valley.
