✍️ Sample UMC Questions & Answers
1. Which term describes a comprehensive plan that sets long-term water supply and demand projections to ensure a utility can reliably serve customers 20–50 years into the future?
An integrated water supply plan (or urban water management plan in some states) projects long-term demand, evaluates supply options, and guides infrastructure and conservation investments to maintain reliability across a planning horizon.
2. The 'revenue decoupling' mechanism breaks the link between a utility's revenues and:
Revenue decoupling adjusts rates so utilities recover a fixed revenue per customer regardless of how much is sold, eliminating the financial incentive to maximize sales over efficiency.
3. A utility's strategic workforce plan reveals that 35% of its engineering staff will be eligible to retire within five years. This finding primarily calls for action in which HR area?
A large impending retirement wave requires focused succession planning and knowledge transfer initiatives to prevent critical skill gaps.
4. A utility transitions from a flat rate to a tiered rate structure. Which customer group is MOST likely to experience a bill decrease?
Under tiered rates, low-consumption customers pay the lower first-tier price for all or most of their usage, typically reducing their bills compared to a flat average rate.
5. A 'buy-in' or 'system capacity' fee differs from an annual service charge primarily because it:
Buy-in fees make new customers pay their proportionate share of the existing system's asset value, ensuring existing ratepayers are not subsidizing new growth.
6. A utility's asset registry shows a pump station with a condition score of 4 out of 5 (poor). What action is most consistent with sound asset management practice?
A poor condition score signals that the asset is approaching end of useful life and should be elevated to capital planning for timely renewal.
