Water filter when using foot (versus electric) pump

If you have a foot pump to your sink, share with me about your water filter system.

I'm pretty clear about the water I drink and have been hauling the drinking and cooking water that I use in my house from a fresh spring for over a decade. I don't drink tap, city, or plastic bottled water. Obviously this makes things not so easy when I need to refill my van water tank. I'll have to deal.

Nothing is set in stone but, as of right now, my plan is to have 18+/-gallon water tank with foot pump. I don't want any more electrical and I also think I'll save more water this way (plus more exercise is good).

How have you set this up? I know there's a filter I can get for at the hose before I fill the tank but what do you do indoors? Does it work well enough with a foot pump? Is there enough pressure built?

TIA for your wisdom and experience. And pics of your set-up would be great, including the ends of the water tank... your set-up for filling the thing.
