Exercise
Scenario:
A waste-to-energy facility uses a significant amount of water in its operations. The facility manager wants to implement water meters to improve efficiency and reduce costs. They currently use 100,000 gallons of water per day. After installing water meters, they notice a 10% reduction in water usage.
Task:
Calculate the daily water usage after implementing water meters and determine the amount of water saved per day.
Exercice Correction
Water usage reduction: 100,000 gallons * 10% = 10,000 gallons Daily water usage after meters: 100,000 gallons - 10,000 gallons = 90,000 gallons Water saved per day: 10,000 gallons
