That sump looks great. You have some solid DIY skills. Just keep an eye out for detritus buildup in that small area before the filter socks.

Tom - I'll be watching for detritus in the drain chamber. From what I have read, the drain flow turbulence in the small chamber keeps the detritus from settling and moving on. I have no practical experience to know if the design or sock silencers will even work. I just mimicked commercial designs. This is on the job training for me :]
