the blue 6 or 7 gallon containers with spigots are convenient( I have 2)... I rotate water from pre hurricane season to next... freeze 2 liter bottles for ice in my 5 day cooler with approaching storms (limited freezer space)....store 33gal non potable water in a Rubbermaid trash barrel in my tub/shower... gives me access to flush toilet (pour into bowl...very slowly) and still have a drain to take a shower.... another 33gal container is placed under the eaves in a wind protected area to catch rain water... neighbor has a 20,000 gal pool... have ordered a Sawyer .1 micron 5 gal filter assembly
