A boil-water order was lifted for Indian Hills residents on Friday night after a second test came back clean.
The test from the lab in Sparks arrived later than expected, according to District Manager John Lufrano.
He said he will use the reverse 911 system to contact residents as well as posting the news on the district's web site at indianhillsnevada.com.
The order was issued after portions of the water system went dry on Wednesday morning after the computer that controls the pumps fried its central processing unit and failed to alert district employees to the problem.
It's standard procedure to issue a boil-water order after a water system runs dry in case contaminants are drawn back into the system through leaky portions.
Lufrano said the first test came back clean on Thursday.
