Is this a community owned pool or is it a privately owned "for profit" pool? If it is privately owned and open to the public for recreational swimming and swim clubs the only incentive the guy has to clean up his act (and pool) is loss of revenue. He can get it in shape for city inspectors and then let it go right back into its unsafe condition. If this is a city owned pool then they should be doing routine inspections and would have performed the needed maintainence. Even if the water gets cleaned up the broken main drain cover is a major violation, and the lack of proper ventilation is going to make someone sick. If this is a city owned or community owned pool and this guy is in charge of maintaining it I would start contacting news media to put some pressure on to make sure it gets cleaned up. Nothing against the coaches but I would be looking for another swim club for my kids, and ask to see the pool's maintainance logs before signing them up.
