Category - Caring for Our Water

Each of the following is a category of water-efficient products for use in industrial, commercial or agricultural applications, except:
  1. Center-pivot irrigation systems
  2. Central core piping
  3. Dental vacuum system
  4. Ice machine retrofits
Explanation
Answer: B - Central core piping is not a category of water-efficient products for use in industrial, commercial or agricultural applications. Center-pivot irrigation systems greatly increase the efficiency of water application for irrigated crops. Dental vacuum systems changed the operation from wet vacuuming to dry vacuuming, thus saving water. Ice machine retrofits change the systems from water-cooled to air-cooled, again saving water.
