Fort Lauderdale is about to get its water from a different place. On Thursday, October 15, at 10 a.m., the city holds the grand opening and ribbon cutting of the Prospect Lake Clean Water Center at 3501 West Prospect Road, the treatment plant built to take over from the Fiveash plant that has served the city for close to 70 years. The city is calling it a landmark investment in the future of its water, and it is inviting the community to come watch the ribbon fall.

For most residents, a water plant is something you never think about until the day it matters. This one is worth a minute of attention, because it is the biggest change to what comes out of Fort Lauderdale taps in generations, and it was designed from the start around the two things people here ask about most: how the water looks, and whether the system can take a direct hit from a storm.

What the new plant actually does

The Prospect Lake Clean Water Center is sized to treat 50 million gallons of drinking water a day. It draws groundwater from the Biscayne Aquifer, the shallow limestone aquifer under South Florida that supplies most of the region, and it sits on the city's Prospect Wellfield site in the northwest part of town.

The bigger change is in how that water gets cleaned. Older South Florida plants, Fiveash among them, were built around an earlier generation of treatment. Prospect Lake runs the water through a newer sequence instead: pressurized filters packed with layers of media, stripping towers, then nanofiltration, which pushes water through membranes with pores fine enough to hold back dissolved material, and finally ion exchange. According to IDE Technologies, the company that designed the process, the ion exchange step is there specifically to remove color.

That detail will mean something to anyone who has filled a glass in Fort Lauderdale and looked at it twice. Treating for color at the plant is the part of the job a treatment plant can control. What happens between the plant and your kitchen still depends on the pipes in between, so expect the change to be a process rather than a switch flipped on Thursday morning.

The plant is also built to stand up to a Category 5 hurricane, which matters in a place where drinking water is one of the first things people worry about after a storm passes.

Why Fiveash is stepping aside

Fiveash has been treating the city's water for nearly seven decades, and when the deal for its replacement was announced in February 2023, the companies involved said the old plant was close to wearing out. Rather than keep patching a plant that old, the city chose to build a replacement from the ground up on a different site.

Construction formally started with a groundbreaking in January 2024, so Thursday's ceremony caps a build of under three years from the first shovel to the ribbon. For an industrial plant this size, that is a quick turnaround.

An unusual way to pay for a plant

How the plant came together is part of the story. Fort Lauderdale did not simply hire a contractor and write a check. It set up a public private partnership with two companies: IDE Technologies, a water treatment firm that has built more than 400 plants in 40 countries, and Ridgewood Infrastructure, a U.S. investor focused on water and utilities. Kiewit, one of the country's largest builders, is also listed as a partner on the city's event flyer.

Under the arrangement, the private partners put up a quarter of the project's cost and carry the risk of building it, along with the long term risk of running and maintaining it. The contract runs for 30 years. In plain terms, if something in the plant goes wrong, a large share of that problem is theirs, not just the city's.

The structure drew attention well beyond Broward County. In 2023 the project was named Best P3 Utility Project of the Year and Water Deal of the Year for water treatment in North America, two industry awards for how the financing and the risk were set up.

If you want to go Thursday

The ceremony starts at 10 a.m. on Thursday, October 15. The plant is on West Prospect Road just west of NW 31st Avenue. The city's map shows the entrance off Prospect Road at NW 35th Avenue, with parking on site north of the road and the ceremony area beside it. Ribbon cuttings like this usually run short, so plan to arrive a little early.

The city says the plant will serve Fort Lauderdale and surrounding communities, so this is not only a Fort Lauderdale story. If your water bill comes from the city, there is a good chance this is where your water will be treated from now on, whether you live near Las Olas, out by the Galt, or in one of the neighboring Broward communities on the city's system.

What it means at home

Most infrastructure news arrives as a bill or a detour. This is the other kind: a plant built to last decades, rated for the worst storm the coast can throw at it, with color treatment written into its design, and with private partners on the hook for running it well for the next 30 years. You will not see it from Las Olas or the beach, but you will drink from it every day.

If you have ever wondered what happens to your water before it reaches the tap, Thursday morning on West Prospect Road is the rare chance to see the answer in person, on the day it officially becomes Fort Lauderdale's.
