Ice Pigging update 6/1/20

During the past two weeks ice pigging has continued in the Mallard Pond and Portofina developments, and over the next two weeks will be performed in the Deer Creek and Briarwood Estates developments. After this phase is complete, the City will temporarily cease ice pigging to assess the results and make a decision about whether to continue, and if so, project location(s) and timing. Throughout the process, it is important to note that workers have performed ice pigging while following CDC, state, and local guidelines in relation to the COVID-19 pandemic.

             Meanwhile, a second round of line swabbing was initiated May 10th with four days of swabbing (May 10-13) this week on Partin Settlement Road, the Osceola County government complex, from the government complex through Emerald Lakes to Neptune Middle School, and Canoe Creek Woods subdivision. Next week’s schedule includes four more days of line swabbing (May 17-20) in the Indian Lakes subdivision, Michigan Avenue from south of Bulldog Lane to the golf course, and the Southern Pines subdivision.  This process, which complements ice pigging, requires the water line to be turned off briefly in order to allow it to be swabbed, disinfected and then returned to service.  Immediately after the water line is turned back on, customers served by the line were placed under a precautionary boil water notice for two days while bacteriological tests are performed to ensure that the line has been properly disinfected. Customers affected by the work were provided several advance notices along with a supply of bottled water for the duration of the precautionary boil water notice period. After next week line swabbing will be paused for the next three weeks while the contractor performs work for other entities, staff prepares areas for additional line swabbing in the latter part of June, and the results are evaluated for further action.             

Customer Service continues to survey customers in developments that have received ice pigging in order to gauge customer satisfaction and gain feedback on the success or any customer issues that may have occurred as a result. The survey is being distributed through Constant Contact and is sent to those customers for whom Customer Service has e-mail addresses. Surveys of Mallard Pond and Portofina customers will be conducted in the coming week.

            Information has been disseminated to customers in the utilities bill insert and through the website instructing them to flush their hot water heater after the water line serving their residence has received the ice pigging. Detailed step-by-step instructions are provided in both the bill insert and on the website.

            We would like to hear from those customers who are still seeing discolored water/particles, or experiencing low pressure after ice pigging is completed. Please contact our Customer Service Department at 407-957-7344, so we have record of the occurrence and can attend to it accordingly. 

Update 5/1/20

   The City has executed a fourth amendment to its contract with Suez to continue the ice pigging process through the month of May, with the City evaluating whether this will ultimately conclude the process. Meanwhile, progress continues with this week’s work in Pine Chase, Cypress Pointe, Canoe Creek Villas, Village Green, Crestwood Apartments, and Inglewood Meadows Apartments. Last week, Environmental Utilities and Suez completed Pawley’s Loop North and South, Natchez Trace, The Sanctuary, Burberry Place and Tybee. Workers have continued the ice pigging while also following CDC, state and local guidelines in relation to the COVID-19 pandemic.

    Line swabbing continued when last week work was  performed on the water main on Canoe Creek Road from just south of 17th Street to the intersection with Old Canoe Creek Road on Monday April 20th and Tuesday April 21st followed by the  water main on Neptune Road from the Police Department to the Cane Brake Subdivision on Wednesday April 22nd.  The process, which complements ice pigging, requires the water line to be turned off briefly in order to allow it to be swabbed, disinfected and then returned to service.  Immediately after the water line was turned back on, customers served by the line were placed under a precautionary boil water notice for two days while bacteriological tests were performed to ensure that the line has been properly disinfected. Customers affected by the work were provided several advance notices along with a supply of bottled water for the precautionary boil water notice period. Line swabbing will be paused for the next 2-3 weeks while the contractor performs work for other entities and staff prepares areas for additional line swabbing later this month.

Update 2/27/20
The “ice pigging” process, activated on February 10, heads toward week four, targeting the most affected by discolored water and sediment. Suez North America, the company contracted to perform “ice pigging” of the main water lines  along Old Canoe Creek Road. Ice pigging is now being done in residential neighborhoods located between Old Canoe Creek Road and Canoe Creek Road. At this time, ice pigging is scheduled to continue through the third week of March and the City is in discussions with the company to extend the contract for additional work.

Ice pigging is an innovative process developed in Europe; it completely cleans the inside of a water line through the process of injecting a thick slurry of ice into a segment of a water line through a fire hydrant. The slurry moves along the inside of the pipe pushing out everything in the line ahead of the slurry (pig) through another fire hydrant downstream. 

“At this point, we are guardedly optimistic that this effort will prove successful,” said Brian Wheeler, interim utilities director. “We are seeing very good results at this early phase and that’s very encouraging.”

Prior to the start of this process the water storage tanks at Water Plant No.4, where the issue began, were cleaned to ensure that sediment that had accumulated in the tanks was removed.

The polishing filters at Water Treatment Plant No. 4 have been in operation since early December. The finished water from the plant is not discolored and does not contain any sediment particles. Working closely with the contractor, the water plant staff continues to monitor the systems to ensure they are in proper working order. With the water treatment plant operating properly the focus is on removing the accumulated sediment and discoloration from the distribution system with the ice pigging.

City Will Activate “Ice Pigging” Next Week To Clean Water System

Beginning Monday, Feb. 10, the City of St. Cloud will activate an innovative new technology known as “ice pigging” intended to effectively clean city water lines. The process will be conducted in some of the most affected residential communities beginning with Old Canoe Creek Road from Neptune south to Zion. The initiative is expected to be completed by March 23.

The ice pigging process will be activated through the use of city fire hydrants where ice slurries are to be injected in order to travel through water lines. The ice essentially scrapes away and captures residual particles that have appeared in residential water. Particles and discoloration are residual effects from failed polishers at the city’s main water plant. They have been replaced with new polisher filters which became operational in December. While the new filters work properly and despite an aggressive unidirectional flushing effort, sediment and discoloration in water has not been completely resolved, prompting the decision to engage the ice pigging process.

“We are optimistic that this process will substantially improve and hopefully resolve the issue of sediment and discoloration for those communities,” said Brian Wheeler, Interim Director of Environmental Utilities for St. Cloud.

The service is expected to conclude on March 23 and will be conducted by Suez Environmental North America.  The cost is estimated at $454,000 and is being paid from Utility contingency funds; citizens will see no rate increase as a result of this process.

The City will begin customer notifications that will direct residents when not to use water during the actual ice pigging process, which is expected to last between two and four hours, as well as the work schedule. Updates will be posted on the City’s social media sites along with Frequently Asked Questions which are updated on an as needed basis.
