DALLAS (CBSDFW.COM) – One danger from post-disaster cleanups is disease, especially from human waste.   A Dallas company already has hundreds of portable toilets throughout the Gulf Coast.

United Site Services is better known more for toilet amenities at outdoor settings, like golf tournaments or construction sites. But hundreds of these are already in Louisiana, and thousands more can be added on short notice.

“We have a lot of emergency services that will call us,” said United’s Senior Account Manager Jeremy Glenn.

United is a national chain with two service centers in North Texas. Besides daily customers, the company also has full-time emergency response teams to help in disasters.

“It is a lot of emergency services ranging from FEMA to the different state departments – just different evacuation centers and things of that nature that already have us as contacts,” Glenn said.

The familiar porta-potty is best known, but there are other sophisticated units.  In addition to chemical toilets they’re also sending these comfort stations complete with flushing toilets and sinks with soap and water.

“We can send shower trailers,” Glenn said.  “We can send portable sinks;  we can send portable restrooms; we can send hand sanitizers and hand sanitizer stations.”

So far 350 toilets, 250 sinks, and nearly 80 showers on trailers from here and elsewhere in Texas. 400 more can be sent from here alone on 24-hour’s notice.

“Post-disaster response is really the most critical because it’s the cleanup involved that’s going to continue to need our services on-site,” Glenn said.

Relief stations provide more than a dose of comfort and privacy; they’re a way to contain waste and fight the spread of disease.

“We have the footprint,” Glenn said. “We have the manpower; we have the equipment and services, and we can even step outside our region and help other regions across the nation to help out.”

There are drivers here waiting to get calls, according to Glenn. Three thousand units from all over the country can be trucked in if the need arises.
