at the same time, the film had a quote that "all drains lead back to the ocean" (nemo escapes from the aquarium by going down a sink drain, ending up in the sea). since water typically undergoes treatment before leading to the ocean, the jwc environmental company quipped that a more realistic title for the movie might be "grinding nemo". however, in sydney, much of the sewer system does really pass directly to outfall pipes deep offshore, without a high level of treatment (although pumping and some filtering occur). additionally, according to the dvd, there was a cut sequence with nemo going through a treatment plant's mechanisms before ending up in the ocean pipes. however, in the final product, logos for "sydney water treatment" are featured prominently along the path to the ocean, implying that nemo really did pass through some water treatment.
