You may spot Honolulu Board of Water Supply contractors in your neighborhoods over the next year.

The agency has hired the Royal Contracting Company and EKNA Services to change equipment in meter boxes that will help make the automatic reading system more efficient.

That is when Board of Water Supply crews drive through neighborhoods to obtain water usage data.

Eighty-thousand units will be changed on O'ahu at a cost of about $5 million.

"Our customers will see somebody in a Royal Contracting uniform and vest and a truck out there on the sidewalk, looking at the meter, opening up the meter box, and doing work in the meter box. We don't want our customers alarmed. This is actually a BWS hired contractor, but we also want to let our customers know to be careful for scams," Ernest Lau of the Board of Water Supply said.

Work will take place seven days a week between 7:30 a.m. and 10:30 p.m. 

The work will not affect water service and there is no cost to customers.

The contractors will be wearing yellow vests with the company logo and will carry ID badges.
