Estimating Home Water Use NeedsEstimating Farm Water Use NeedsSources of Water Use EstimatesIn general, we use 50 to 100 gallons per per per day in our homes (200 to 400 gallons per day for a family of four). The household water use estimates given in Table 1 can be used to calculate more specific daily water use values for your home. For the purposes of planning a water system, the total daily water use is less important than the peak daily water use or the peak demand. In reality, most of the water used in the home occurs ovSee more on extension.psu.eduEstimated Reading Time 6 minsPublished Jun 11, 2015Tank Volume CalculatorTotal volume of a cylinder shaped tank is the area, A, of the circular end times the length, l.
