    I was looking forward to hearing your take on this, Rjonsun.
    Rob is very well informed but with your background you have the capability of detailed observation & a description that very few can offer...thank you.

    I've always heard the color of the water is caused by the color of the peat that washes down the river after a rainstorm in the hills.

    I wonder what some of the more unexpected things turn up on those bar grates....

    Overview of the plant. On the first photo you can clearly see the 3 large pans on the right side of the plant. The water enters from the headworks at the foreground. Barely into the first pan you can see a type of baffle or dike that keeps any floatables or heavy sludge from passing farther into the pan. It is then cleaned out by the workers, but I don't know how often. The second shot shows all 6 pans which is in a 3 pan side by side configuration. Water enters equally into the top two pans and flow through the system.

    The first photo shows how the water used to flow from one pan to the next, through these large tubes. They have been filled with cememt. The second photos show the new weir system with a baffle that more efficiently allows water to flow from one pan to the next. This would be similar to something in the States.

    The first 2 photos are from 2011 and show the final pan flowing to the pipe which goes to the river a distance of about 50 feet or so.

    The next photos are recent and show a now grated final pan flowing to the pipe. The effluent quality seems about the same both years.....GREEN, which is the expected algae. The last photo is in the final pan and shows how green the water actually is! Some of the previous overview photos of the plant give the indication the water was blue, but that was just the sky reflection. I'm guessing that a couple hundred feet downstream from the outfall you can not see any green in the water anylonger.

    Some of the birds which were abundant. A nice shot of some of the workers. I thinks there were 5 there that day. Two of the fellows I recognized from the previuous visit.

    Yes, I do drink the tap water in Jamaica. negril tap water isn't coming from that section of the Negril River.
    Some of the stuff I've found on a bar screen???? Gold fish, snakes, wood, stones, walnuts, religous medals, underware and clothing, little kids plastic toys (we actually have a little display of this...I know, you have to have a twisted mind) US paper money (and we do disinfect it and spend it but don't tell the recipient). But the wierdest thing we ever found was a glass eyeball.
