Water suppliers in the greater Tampa Bay region share how they prepare for storms like Hurricane Ian

A water expert explains how the Tampa Bay region can prepare utilities for a storm similar to Hurricane Ian. Plus, some providers in the area share what precautions they are taking to fortify their systems.

Hurricane Ian knocked out electricity in much of Southwest Florida, which cut power to pumps that deliver freshwater to homes and businesses. The underground system of pipes that deliver the water was also damaged, leading to a loss of pressure and possibly contaminating the drinking water supply.

In response, much of the area was placed under a boil-water notice that lasted for weeks.

So would the utilities that deliver water to residents in the Tampa Bay area be able to continue operating if the region took a direct hit from a similar storm? To find out, WUSF reached out to several water departments in the area along with Tampa Bay Water, which supplies drinking water to government utilities that serve more than 2.5 million people in parts of Hillsborough, Pinellas and Pasco counties.

Tampa Bay Water

Charles (Chuck) H. Carden is the general manager of Tampa Bay Water.

The agency's facilities are tested every 10 years, according to Carden.

"We do 'what if' scenarios. If we lose any power or loss of water or a pipe, how do we get water to our customers? And then that report will show where we're weak in certain spots and then we will put in capital improvement projects to try to eliminate that from happening," he said.

Carden said they have backup generators at their critical facilities.

"And then you want to look at where your pipes are exposed to possibly wind damage and so you would harden them up or go underground with them where you can so you won't have pipes being blown off because of the wind," Carden said.

But the agency just collects the water, which means it's up to each individual government utility to maintain the distribution of water to their customers.

Hillsborough County

The director of Hillsborough County’s Water Resources Department, Lisa Rhea, said in an email that their facilities are equipped with diesel-powered emergency generators, which are tested monthly, to provide electricity in the event of a power outage.

Rhea said that when a tropical event approaches, they top-off the diesel storage tanks, which can provide four to 14 days of continuous operation depending on location and water demand from customers.

“In extreme disasters, like what Lee County faced with Hurricane Ian, the supply chain is disrupted. This is evident to the public at gas stations and grocery stores but it also impacts the supplies needed to run water plants,” she said. “The delivery of diesel and other important supplies, like chlorine for disinfection, may be delayed because the delivery trucks cannot get to the locations.”

She added that breaks in the pipes are often not within officials’ control, as underground pipes sometimes get wrapped by tree roots. The rain from a storm can soften the soil, and then the wind or storm surge can knock trees down, pulling the root-wrapped pipes along with them.

“There is one major difference to keep in mind when comparing Hillsborough County’s water system to Lee County’s water system: the lowest elevation water treatment plant elevation is 25-feet above sea level so we would not have been impacted by the storm surge seen in Lee County,” said Rhea.

“Unfortunately, coastal facilities, like those in Lee County, were under water from the storm surge which can damage electrical equipment and contaminate tanks or other systems.”

Tampa

The Tampa Water Department also maintains several days’ worth of fuel onsite at their water treatment plant to power backup generators in case of a power loss, according to Sonia M. Quiñones, supervisor of Communications and Conservation.

She said that as part of their advance prep for Ian, they also had dozens of employees who remained onsite during the storm to ensure normal water treatment operations continued throughout.

“Our distribution team — which is responsible for maintaining and repairing water mains and other assets in our service area — had teams that mobilized at an Emergency Response Center (ERC). They stayed there to respond to emergencies (until they had to hunker down for the storm) and then went into action afterward to clear out their assigned routes of debris and assess post storm needs,” she said in an email.

Plus, in anticipation of the expected high amount of rainfall, the city’s Water Production team coordinated with the Southwest Florida Water Management District to lower the level of water in the Hillsborough River Reservoir.

“We lowered the reservoir by 2.5 feet over the course of three days immediately before Ian hit the area. This action was taken as a flood control measure. We ultimately released approximately 500 million gallons of water,” she said.

Pinellas County

The utilities department provides drinking water, sewer, and reclaimed water services to more than 500,000 residents and 6.7 million annual visitors to unincorporated Pinellas County, department officials said in an email.

As part of their annual emergency preparedness, Pinellas County Utilities employees participate in training and seminars to practice responding to different emergency scenarios. They are required to complete FEMA training related to their emergency role.

The county also ensures all backup power systems are periodically maintained and fueled, the email said. Pinellas is a member of the Florida Water/Wastewater Agency Response Network, a utilities network supporting disaster response, and has preapproved agreements to rapidly deploy resources across state jurisdictions. Plus, the county assesses regular wastewater and drinking water systems to identify and test equipment and resources used for disaster response.

"Should a Category 3, 4, or 5 hurricane make direct landfall in Pinellas County, there could be significant issues related to drinking water pressure, drinking water quality, and sewer system operations. Pinellas County includes information on what to do if the water supply is affected and if there is a sewer outage in its Hurricane Preparedness Guide," officials said in the email.

St. Petersburg

The city of St. Petersburg also has the option for generator power at its two pumping stations at Washington Terrace and Oberly.

"Both pumping stations are located on relatively higher elevations and should not be as impacted as the rest of the city from flooding inundation," said John Palenchar, director of Water Resources, in an email.

"The pumping stations are redundant and the city can be supplied with water from either one of the pumping stations if one is unable to operate."

St. Petersburg also has an Emergency Water Distribution Plan, in case a severe storm or other event limits the use of their regular system. The plan is focused on the distribution of water to the community before the arrival of disaster relief aid from Florida and/or the Federal Emergency Management Agency.

"During storm preparation, the EWD Plan requires reserving 18 million gallons of water in storage tanks at the Oberly and Washington Terrace water pumping stations. Based on providing up to 2.5 gallons of drinking water per person per day, this storage is sufficient to serve the city’s population for several days," Palenchar said.

Water operations officials in Pasco County did not respond to emails and/or calls for this story.
