Dear school children!

Dear school children!

The well-deserved break is finally arrived!

After we hung out together on the Central wastewater plant in Zagreb, during the last school year, we expect your interest in the following school year to.

Until then, draw, write, sing, rejoice, swim, have fun and rest for the new school days in the fall.

Have a lovely school holidays!

Your ZOV team
