City’s new solar compacting mailboxes allowing for even less frequent collection


Has that letter you mailed four weeks ago--or even four months ago--arrived at its destination? Did you think your package was lost in the mail? Did you call the Postal Service to complain? Perhaps you resent your letter or package ... several times.

Well, with the city's new solar compacting mailboxes, chances are your mail is likely still in the box, and, at one-twentieth it's original size.

The City of Philadelphia and the United States Postal Service have agreed that the latest attempt to streamline costs (email and text messaging are greatly reducing USPS revenue) has been a huge success. The USPS Solar Mailbox Pilot Program began in Philadelphia in June with about 20 units, with more added every couple of weeks. They can be seen at many corners in and around Center City and, as the name suggests, are powered by the sun.

“With these solar compacting mailboxes I can go three to four weeks in between pickups for some of the mailboxes on my route,” said Rebbecca Stevens a mail carrier in the Fairmount section of Philadelphia.

"I haven't even looked in that mailbox since July," said Hank Tanner gesturing towards a box on Front Street.

What does it take to increase the capacity of a standard size mailbox by twentyfold? How about 30 tons of compacting force per square inch of diamond-coated steel. Engineers agree that there is a fine line between compacting and turning your mail into pulp.

"Thirty-one pounds per square inch was turning a simple letter-size envelop into apple sauce. We are really urging customers not to place small boxes with fragile or non-fragile items into the new mailboxes," said Betty Sharon a consultant to the pilot program and employee of Lockheed Martin. "Unless the boxes are steel and concrete reinforced, but even then I wouldn't do it."

Though the less frequent collections are benefiting postal carriers, customers are experiencing much longer delivery times for a simple letter.

"My cable, electricity, water and heat have all been turned off," said Greg Dallenbach. "[USPS] is telling me my September heating bill should arrive at PGW any day now."
