Narrative:

The 'a' flight attendant called the cockpit and said he had a big problem; all the lavatories were full. After contacting dispatch and maintenance and the captain checked the lavatories herself; it was determined the lavatories were all full. Den was decided as the divert airport as we still had 3 hours remaining in the flight. We diverted into denver for full lavatories. It appeared bos svced the lavatories with blue fluid; but did not empty them. On ground in den; we had to wait for a guide man; had to call for lavatory trucks; and had to call for the fueler. No customer service supervisor met the flight.
