1.6 Utility Management, Administration & Recordkeeping

Management questions surprise candidates who prepared only for process chemistry. The official MoDNR test descriptions list MANAGEMENT as a scored objective on Drinking Water C (3 items plus 1 calculation), Distribution System 1 (3 items), Distribution System 2 (1 plus 1 calculation) and Distribution System 3 (3 plus 1 calculation). Small-system operators are frequently the whole management team, so the exam treats administration as core competence.

Records: What to Keep and For How Long

Record retention is the most concrete management topic and the easiest to test.

Missouri layers its own requirements on top. Operators must maintain the drinking-water operating reports required by the applicable rule, approval or department form and the DMRs required by each wastewater permit, plus the facility’s daily logs, chemical-use records, calibration records and approved/as-built system records. The department's renewal training rules explicitly credit courses on record keeping, which tells you how the regulator views its importance.

A practical rule: the log entry must let a stranger reconstruct what happened. Time, reading, action taken, and the initials of the operator who took it. Entries are made in ink, and corrections are struck through with a single line and initialled — never erased or overwritten, because an altered log is evidence of falsification, which is grounds for revocation.

Rate Structures and Financial Management

A public water or wastewater utility must fund three separate things:

1. Operations and maintenance (O&M) — chemicals, power, labour, laboratory fees, routine repairs.
2. Debt service — principal and interest on loans such as State Revolving Fund borrowings.
3. Capital reserve / depreciation — money set aside now to replace assets that will fail later.

The classic small-system failure is setting rates to cover only the first two. The plant runs, the loan is paid, and nothing is saved. Twenty years later the clarifier drive or the elevated tank needs replacing and there is no money, so the system defers, deteriorates and eventually faces an emergency rate increase or a consent order.

Water Loss and Unaccounted-For Water

$\text{Unaccounted-for water (\%)} = \frac{\text{Water produced} - \text{Water sold}}{\text{Water produced}} \times 100$

Worked example. A system pumps 42.0 million gallons in a year and bills 35.7 million gallons.

$\frac{42.0 - 35.7}{42.0} \times 100 = \frac{6.3}{42.0} \times 100 = 15.0\%$

The simple percentage is useful for trending, but it is not a universal pass/fail band and “produced minus sold” also includes authorized unbilled use and data error. Validate production/customer-meter periods, estimate authorized uses, separate apparent from real loss, and compare the result with the utility’s baseline and a recognized water-audit/economic-loss analysis. Investigate material changes and losses. Common components include:

• Real losses — leaking mains, services and joints; overflowing storage tanks.
• Apparent losses — customer meters under-registering as they age (worn meters read low, never high), billing errors, and data transfer mistakes.
• Authorised unbilled use — hydrant flushing, main disinfection, fire fighting, street cleaning. This should be estimated and recorded rather than absorbed into "loss".

Staffing, Coverage and Certification Management

• Every classified facility needs a chief operator certified at or above the facility's classification, and the owner must notify MoDNR in writing within fifteen calendar days when the chief operator is replaced.
• Certificates renew every three years, and the renewal hours differ by level. A manager running a small system with a DS-I operator budgets 10 hours per cycle for that person; a DS-III operator needs 30.
• Succession planning matters disproportionately in Missouri's many small systems: a single certified operator retiring can put a system out of compliance overnight, which is why the department funds an operator certification training voucher program.

Public Communication

• Consumer Confidence Report (CCR): every community water system must deliver an annual water quality report to its customers by July 1 covering the previous calendar year, listing detected contaminants, MCLs, likely sources and any violations.
• Public notification: tiered by severity. Tier 1 (acute risk, such as E. coli presence or a nitrate MCL exceedance) requires notice within 24 hours by broadcast media or hand delivery. Tier 2 requires notice within 30 days. Tier 3 may be included in the annual CCR.
• Boil water orders, main break notifications and planned outage notices are operational communications the operator usually drafts and the department may review.
