David.......you must use a couple of large settling tanks first, into those tanks you would add our 100% organic solution, SOLUTEK. Inlet to tanks needs to be filtered at about 60 to 100 microns. Once water has an average residency time of 7 days it will be relatively clean.....then there are several ways to go...either filter again at 3 to 4 microns and use UV sanitation of filter at .03 microns and it will be perfect to drink. It all depends on just how far you want to go. If you ony filter once and users can boil the water for 8 mins. it will be safe.
