The island's aging water systems are set for a major overhaul, and it could come with a hefty price tag. This morning, the Consolidated Commission on Utilities gave the go-ahead for Guam Waterworks Authority to pursue a $250 million bond borrowing, part of a massive effort to fix leaks, upgrade wastewater systems, and tackle new contaminants like PFAS and dieldrin.

If approved by the Guam Economic Development Authority and the Public Utilities Commission, GWA hopes to hit the bond market by July. But this is just the beginning. GWA's five-year plan outlines nearly $900 million in improvements, much of it to comply with a federal settlement over environmental standards. And by 2037, GWA is expected to spend as much as $3 billion.

The funds will be repaid over time, with monthly water bills expected to rise by around $20 for most residents starting October 1. Officials say the increases are already baked into rates through 2029, but more hikes could come if future borrowing is needed.

Still, leaders stress the upgrades are necessary, and say they’re looking to Washington for help to ease the burden on ratepayers.
