I agree. More information regarding your process and product makes a huge difference regarding the answer.
"Our plant is looking to start running production 24 hours a day for 4 days a week with one cleaning of production equipment at the end of the week."
Depending on the products and environment you are producing them in, when you validate your SSOP you might find that you've stretched it just a little too far (environmental swabbing, etc.). Your sanitation chemical rep should be able to assist you with validating the SSOP, and also recommending other (expensive) systems to put in place in order to make extended runs possible (i.e. sanitizer sprays for conveyor belts).
"One question I have is that we have several drains and standing water areas that need to be sprayed with a higher concentration of sanitizer."
Is it possible to repair poor drainage areas and eliminate the standing water instead of figuring out how much sanitizer you need to dose the problem areas with?
It's dangerous territory when you try to cancel out increased risk with improved production.
Wish you the best of luck with this project!
