4 uses 400 gallons of potable water per day 1 . Over the course of the summer (June-August, 92day s) Parkland / Spanaway receives approximately 0.93 inches of rain . 2 1. Calculate how many gallons of water storage are req uired to meet the average four-person household’s use for th e summer (3 points). 2. Determine the area of the of a moderate-sized Par kland House roof (see measurements in Figure 1 to the right”3 p oints) 3. Assuming we could capture all of the water that h its the roof, determine how many gallons of rainwater on average are expected to be replenished over the course of the summer. To complete this calculation (include units in your answer!): a. Convert the inches of summer rainfall from above into feet (3 points) b. Multiply your answer in part a by the area in square feet you’ve calculated for th e roof. This will give you a giving you a volume of water in cubic fe et for the entire summer. (3 points) c. Convert cubic feet of water to gallons (1 cubic f t. = 7.48 gallons); this is your estimated summer recharge value in gallons (3 points) 4. Now determine how much additional water catchment or storage would be needed to meet the water needs for the entire summer using rainfall, by subt racting your estimated summer recharge from the tot al volume needed. (3 points) Part IV: What do our data tell us about water and s oil resources at PLU and in Parkland? (28 points) For the questions below, refer to your field data a nd rainwater calculations. 1 2 Figure 1 Part III: What volume of rain barrels are required? (18 points) In this exercise, you will calculate what volume of storage is required to capture enough rainwater to sustain the average use of a household of four for a summer in the United States. An average US household of four 5 1. Use your soil infiltration rates and soil profile data and attempt to infer why the different locati ons may have had different infiltration rates. (10 points) 2. If someone were modifying a yard in Parkland that h as soil and infiltration characteristics similar to campus with sustainability in mind, what modificatio ns would you recommend to maximize sustainability based on what you’ve learned about campus soils? For this question, first provide your definition of a sustainable yard, and then explain your recommendati ons using your field data. (8 points) 3. Storing enough water for what the average US hous ehold would use would take an enormous amount of capacity. Rather than design for the average usage, we can reduce the amount needed by conserving water. What three actions would you taking to reduc e the storage needed?
