The Oak Brook Village Board approved the sale during its virtual meeting on Tuesday night, giving Aqua Illinois control of a portion of the water in Oak Brook.

“Without selling this, our water rates go up 48 percent for our residents, who voted for us to come and do sensible things,” said Oak Brook Village Trustee Ed Tiesenga.

Supporters claim the sale will save millions of dollars in the long run, but critics say they are worried about Aqua’s track record.
