For Businesses


We are committed to providing a high level of service at a reasonable price through responsible and strategic fiscal practice. We take a financially responsible, proactive approach to protecting our water system infrastructure. We proactively replace and upgrade equipment, as needed, to prevent system breakdowns and service disruptions and minimize even bigger potential costs in the future. We count on our collaborative business partners to help us with that process.

This may include the businesses we serve, our investors, and the contractors with whom we work.

We are transparent about how we select the partners and contractors that assist us in maintaining our exceptional levels of service. We post all open requests for proposals (RFPs) to invite qualified contractors and businesses to submit their proposals to work with us.

Additionally, we post all of our fees and permit applications online for accessibility and transparency, and our latest financial reports are available to the public for the current and previous years. We also share recent Fitch and S&P Global ratings reports.
