Welcome to the St. Cloud Utilities Customer Service Water Information Portal. The purpose of this page is to keep residents and customers of the Utility System informed on a variety of topics of concern including water quality and discoloration, updates on the utility projects and ongoing efforts to address water concerns. 

Water Quality

The City of St. Cloud Environmental Utility department takes drinking water samples regularly for testing by a third-party laboratory to ensure that the drinking water meets all regulatory requirements and is safe to drink.  The results of these samples are reported to the Florida Department of Environmental Protection (FDEP) which is responsible to the Environmental Protection Agency for administration of the federal Safe Drinking Water Act for the State of Florida.  The FDEP requires that all municipal water systems sample and test for a number of Organic and Inorganic Chemicals, Radionuclides, Disinfection By-products, and Bacteria. In all, the City tests for 80 different compounds, disinfection by-products 4 times a year, 70 bacteriological samples every month. To date the City water system is incompliance with all water quality parameters.

Water Treatment Plant No. 4 Polishing Filter Replacement Project

The City of St. Cloud’s Water Treatment Plant No. 4 utilizes two Polishing Filters to catch and remove resin and other fine particles (the main cause of water discoloration) after primary treatment.  The original Polishing Filters structurally failed and lost operational capacity.  In 2018, the City implemented a project to replace the failed polishers. The project’s main objective is to replace the two existing aluminum Polishing Filters with stainless steel Polishing Filters.  The project also includes replacement of valves and new instrumentation. Completion of the project is anticipated soon. 

*UPDATE as of January 14, 2020

In an effort to resolve ongoing issues associated with the City’s water filtering system, the Utilities Department will soon be implementing an innovative new technology with the capability to effectively and efficiently clean city water lines.    

Known as “ice pigging,” the process injects an ice slurry into a water line through a city fire hydrant, pushing the slurry through the line only to exit through a different fire hydrant. This process has the potential to fully clean a water line. St. Cloud learned about and investigated ice pigging after it was used successfully by neighboring Orange County Utilities.

This new step comes after installation last December of two new polishing filters at Water Treatment Plan No. 4. The filters went online in December and are working properly and creating clean water. Turbidity, clarity of the finished water, has improved significantly with the new polishers. Meanwhile, filter optimization and backwashing sequences continue as part of the process. However, resin particles that were lost to the system from the previous failed polishers remain in the system and continue to impact residents in their homes.

Environmental Utilities has completed two cycles of unidirectional flushing through the areas most impacted by discolored water and sediment. While this process has shown positive results in removing large amounts of sediment and discoloration, it has not significantly improved the overall water quality in the affected areas. The City is evaluating the unidirectional flushing process to improve outcomes from this process.

The City Council approved $407,000 for the ice pigging initiative with monies in the utilities budget; residents will see no rate changes as a result of this issue. The ice pigging, which is expected to begin in early February and take about five weeks, will target the areas affected most by this issue, which equates to about 27.5 miles of water line. 

As stated earlier, the City is keenly aware of the inconvenience and unpleasant nature of this issue. Our intent is that this high technology process will substantially improve the water quality and significantly reduce the incidents of discolored water. .

Unidirectional Flushing Program

The City’s Unidirectional Flushing Program is our main tool in tackling the water discoloration and sedimentation issue in the distribution system.  Unidirectional flushing is different from conventional flushing in many ways.  It involves manipulating valves to divert flow and create high scouring velocities in the pipes to flush out the accumulated resin sediment. The Unidirectional flushing program is progressing in a systematic manner through the portions of the water distribution system most impacted by the resin sediment in the water. The City anticipates that it will take several rounds of the Unidirectional flushing to clear the distribution system in these most affected areas. 

The City of St. Cloud is committed to providing clean drinking water to all of its users.  The City is also committed to being as transparent as possible with any challenges that the Utility faces.  We will keep this web page updated weekly to provide relevant information about the water quality and project progress.  For any additional questions, please reach out to the Utility’s Customer Service Center at 407-957-7344 or

Flushing program questions and answers

What is hydrant flushing?

 Hydrant Flushing refers to flowing water at high volume for maintenance purposes. Periodically you will see Environmental Utilities personnel flushing hydrants in your area. This is done to remove sediment from pipes in order to maintain clarity and quality in the distribution piping. 

Why is it important to routinely flush the water system?

 The City flushes the water distribution system to improve water quality by removing sediment and scale that builds up over time. 

When does flushing normally occur?

Environmental Utilities personnel flush weekly throughout the year so that the water does not stagnate in less active parts of the water distribution system. 

Is Environmental Utilities the only ones that flush the lines?

No, Fire Departments are required to flush hydrants when they are testing hydrants to make sure adequate flow and pressure is available.

Will I be told when the City is flushing my area? 

The City will provide notification of the area in which flushing will occur in advance through posting signs, email notifications, online, and automated calls. We ask for everyone’s patience during flushing and that you do what you can not to be adversely affected by the water quality that may result during this time. To find out when flushing is scheduled to happen in your area, please visit

How will this affect my water? 

During the flushing process, water customers may experience fluctuations in pressure and discolored water. Although the water does not pose a health risk, it is recommended to avoid drinking the water until it runs clear. It is ok to use the water for showering, bathing, and toilet flushing. Do not use for laundry.

What should I do if my water is discolored after flushing?

If you notice discolored water after flushing, turn on several cold water taps in your home to allow new water to work its way into your pipes. Let the water run for several minutes until the discoloration is gone and the water runs clear. In some infrequent cases, customers may experience slight discoloration for a few hours. This discoloration only affects the appearance of the water; it does not affect the water quality or taste. Do not do laundry until completely clear. If discoloration continues, please contact customer service at 407-957-7344.

What should I do if my water pressure is still low or I have no pressure?

If you are experiencing low pressure at only one or two taps, remove and make sure the aerator or screen is clean. If you have low water pressure in your entire house, the meter or service line could be plugged. Please call customer service at 407-957-7344.

Is water main flushing a waste of water?

No. Flushing is an essential part of water system maintenance. It is the most effective way to keep our drinking water safe, clean, and pleasant tasting. Our technicians keep very accurate records of the amount of water that is being flushed, so this water is accounted for and tracked.
