Spilling Over

I was doing some work photos at a scheme we are completing in Wakefield (may upload some of the shots later) when the sun disappeared and ruined my afternoon. So I turned my attention to something different and found this weir on a 35m diameter final settlement tank. The water is treated effluent ready to be discharged to river. Fairly clean but I certainly wouldn't drink it
Would this be better as a mono given the lack of colour anyway?
Any other comments very welcome.
