The winning student artwork in the Phoenix Water Department's "Only Rain in the Storm Drain" contest has been turned into official bookmarks currently available for free at all Phoenix library locations.

The winning designs were entered by Levi Wyatt,  9,  first place; Chinmayi Adiga,  12, second; and Winston Reed,  7,  third.

Besides the honor of having their designs turned into bookmarks, winners received a collection of Phoenix Water Department educational materials and souvenirs.

There were 93 entries and 16 finalists.

The judges were Phoenix Mayor Kate Gallego; Rita Hamilton, city librarian; Nazario Prieto, water department assistant director; and Jennifer Calles, water department deputy director.

They evaluated each entry for artistic quality, message, creativity and clarity.

"The bookmarks serve as a critical reminder that only rain should go in the storm drain," city officials stated in a release.

"It's an important message during monsoon season because it's common for people to misuse storm drains by dumping trash and other contaminants in them that can end up in streams and rivers."
