Save Water and Money with a Pool Cover!

How can a family save water with a pool cover?

If a family has a rectangular swimming pool that measures 15 ft by 20 ft and water evaporates from the pool at a rate of 50 gallons per square foot per year, how much water can the family save by using a pool cover that reduces evaporation by 90%?

Answer:

By using a pool cover, the family can save an impressive amount of water!

Final Answer: Using a pool cover can save the family 13,500 gallons of water per year.

Explanation:

To find out how much water the family can save with a pool cover, we first calculate the evaporation rate without the cover. The area of the pool is 15 ft x 20 ft = 300 sq ft. At a rate of 50 gallons per square foot per year, the total evaporation for the pool is 300 sq ft x 50 gallons/sq ft/year = 15,000 gallons/year.

When using a pool cover that reduces evaporation by 90%, the family will save 90% of the evaporation amount, which is 0.9 x 15,000 gallons = 13,500 gallons/year.

Therefore, by simply using a pool cover, the family can save a significant amount of water and money in the long run! It's a win-win situation for both the environment and your wallet.
