Which of the following is NOT a type of water rate structure?

• A. Uniform Rate
• B. Linear Rate
• C. Seasonal Rate
• D. Increasing Block Rate

Answer: (B)

Pricing water is about how charges change with how much you use or when you use it. The familiar structures include a uniform rate, where every unit costs the same; a seasonal rate, with prices that vary by time of year; and an increasing block rate, where the unit price rises as you use more water. A linear rate isn’t treated as its own distinct structure; it’s simply a constant price per unit, a straightforward proportional charge. That lack of tiering or seasonal adjustment means it isn’t considered a separate rate design, even though it results in a direct, linear relationship between usage and bill.
