In buildings closed by virus, stagnant water can become dangerous
Share Now on:
With restaurants, stadiums and schools closed down, there is a lot of water idling in plumbing systems right now. Scientists say that’s not a healthy state of affairs. Stagnant water can accumulate heavy metals and harmful bacteria — like the kind that causes sometimes-fatal Legionnaire’s disease.
The Environmental Protection Agency has issued guidance on how shuttered facilities can safeguard their water systems — for whenever people return.
So, which water systems are at risk?
“All of them,” said Caitlin Proctor, a microbiologist at Purdue University. “Any building that has had less water use than normal is going to have some sort of water quality deterioration.”
Proctor co-authored a report raising concerns about lead and copper buildup. But she’s especially worried about certain kinds of bacteria — with fancy scientific names.
“These include Legionella pneumophila, Mycobacterium avium,” she said.
One way to kill off bad bugs is “shock disinfection.” That’s when an engineer floods the pipes with a boatload of bleach before people start using the water again. But that can cost tens of thousands of dollars per building. Proctor said there’s a cheaper alternative.
“The best way to prevent these kind of issues is to keep the water moving,” she said.
With people gone, keep the taps — and other plumbing fixtures — on. Simple enough for a stand-alone office building, but what if you run, say, a massive university campus with a marathon’s length of water pipe and north of 100 buildings? Can you really keep all those toilets flushing?
“Actually, we are,” said Gary Rudolph, senior utilities manager at the University of Central Florida. Usually, campus plumbing serves 40,000 students. But now, things are sort of quiet, Rudolph said. With no students, letting the water run is a full-time job. Maintenance crews visit each building every other week.
They’re “making sure all the urinals are flushed, the toilets are flushed [and] the faucets are run,” Rudolph said. It’s essential work that costs $1,300 a day in labor. But Rudolph said the empty school is using water at two-thirds its normal rate. “If there’s any showers in the building, we run those.”
While it is resources going down the drain, he hopes it will save the university from having to pay for shock disinfection down the line.
“And when people come back to campus, it will be just normal,” Rudolph said. “You just come back, take a shower, drink the water. Do whatever you normally do when they were here before.”
There’s still no word on when students will be back to do the flushing.
COVID-19 Economy FAQs
What’s the latest on the extra COVID-19 unemployment benefits?
As of now, those $600-a-week payments will stop at the end of July. For many, unemployment payments have been a lifeline, but one that is about to end, if nothing changes. The debate over whether or not to extend these benefits continues among lawmakers.
With a spike in the number of COVID-19 cases, are restaurants and bars shutting back down?
The latest jobs report shows that 4.8 million Americans went back to work in June. More than 30% of those job gains were from bars and restaurants. But those industries are in trouble again. For example, because of the steep rise in COVID-19 cases in Texas, Gov. Greg Abbott, a Republican, increased restrictions on restaurant capacities and closed bars. It’s created a logistical nightmare.
Which businesses got Paycheck Protection Program loans?
The numbers are in — well, at least in part. The federal government has released the names of companies that received loans of $150,000 or more through the Paycheck Protection Program.
Some of the companies people are surprised got loans include Kanye West’s fashion line, Yeezy, TGI Fridays and P.F. Chang’s. The companies you might not recognize, particularly some smaller businesses, were able to hire back staff or partially reopen thanks to the loans.
