Five Ways Small Utilities Can Save Money Without Sacrificing Water Quality

Jul 24

For a small water utility, every dollar matters.

Unlike large systems with dedicated engineering departments, maintenance divisions, laboratories, and substantial capital budgets, smaller utilities may have only a handful of employees responsible for keeping an entire system operating.

Meanwhile, the bills don't stop.

Chemical costs rise. Electricity costs fluctuate. Pumps wear out. Water mains break. Regulations change. And customers still expect safe drinking water every time they turn on the tap.

The answer isn't cutting corners. It's operating smarter.

EPA's guidance for rural and small systems emphasizes improving performance through effective management, assessment, prioritization, and measurable improvements.

Here are five areas where small utilities can potentially reduce operating costs without sacrificing water quality or reliability.

1. Optimize Chemical Feed—Don't Just Feed What You've Always Fed

One of the easiest habits to develop in water treatment is also one of the most expensive:

"That's what we've always fed."

Chemical dosages should respond to actual water conditions—not just historical settings.

Raw-water quality changes throughout the year. Temperature, pH, alkalinity, turbidity, organic matter, ammonia, and other characteristics can influence treatment performance.

Depending on the treatment process, optimization may include evaluating:

Coagulant dosage
Polymer dosage
Disinfectant feed
Ammonia feed
pH adjustment
Corrosion-control chemicals
Fluoride feed, where applicable

Chemical-feed optimization isn't simply about using less chemical.

It's about using the correct amount.

Underfeeding can create treatment and compliance problems. Overfeeding can waste money and potentially create additional water-quality problems.

WaterOperator.org notes that chemical-feed control is a critical treatment step and identifies equipment failures, changing source-water characteristics, and temperature changes among factors that can contribute to chemical-feed problems.

Start with the data

Operators should routinely compare chemical dosage against treatment performance.

Look at trends.

If a plant increased coagulant dosage six months ago because of a raw-water event, ask whether that dosage is still necessary.

If disinfectant demand changes seasonally, determine whether the feed rate should change with it.

And when appropriate, use tools such as jar testing, online instrumentation, laboratory data, SCADA trends, and calculated feed rates to support those decisions.

A few unnecessary gallons of chemical every day might not look significant.

Multiply that by 365 days, however, and suddenly you're talking about real money.

2. Make Your Pumps Work Smarter

Pumping water isn't cheap.

In fact, energy can represent a substantial portion of a drinking water utility's operating expenses. EPA estimates that energy can account for as much as 40% of operating costs for drinking water systems and says efficiency improvements can potentially reduce energy use and costs considerably.

That makes pumps a logical place to look for savings.

A pump operating inefficiently doesn't necessarily announce itself with an alarm.

It may simply keep running—and keep increasing the electric bill.

Common efficiency problems can include:

Worn impellers
Improperly sized pumps
Excessive throttling
Poorly maintained motors
Operating outside the pump's efficient range
Unnecessary pressure
Inefficient pumping schedules
Frequent starts and stops

Utilities should compare pump performance over time.

Track things such as:

Flow + discharge pressure + runtime + energy consumption.

If the same pump now requires substantially more runtime or electricity to move the same volume of water, something deserves investigation.

Variable-frequency drives (VFDs) may also improve efficiency in appropriate applications, but technology isn't automatically the answer. Sometimes the cheapest efficiency improvement is simply repairing and properly operating the equipment already installed.

3. Preventive Maintenance Is Cheaper Than Emergency Maintenance

There's an old rule in operations:

Equipment rarely breaks when it's convenient.

The pump that has been making a strange noise for three months probably won't fail Tuesday morning when the maintenance crew is fully staffed.

It'll fail Saturday night during peak demand.

That's just how Murphy runs his utility.

Preventive maintenance helps small systems break this expensive cycle.

WaterOperator.org highlights preventive-maintenance resources specifically developed for small systems, including tools for tracking daily, weekly, and monthly O&M activities and preserving system knowledge.

A basic preventive-maintenance program should address critical assets such as:

Pumps
Motors
Valves
Chemical feeders
Analyzers
Generators
Storage facilities
Electrical equipment
Instrumentation
Emergency equipment

The objective isn't to maintain everything equally.

Prioritize equipment based on the consequence of failure.

Ask:

What happens if this piece of equipment fails tonight?

If the answer is "We lose treatment capacity," "We can't maintain pressure," or "We risk compliance," that asset belongs near the top of the list.

Asset management helps utilities understand asset condition and future needs so that investments can be prioritized before failures become emergencies.

A $500 repair performed today can be considerably cheaper than an emergency callout, equipment replacement, lost production, and regulatory problem tomorrow.

4. Stop Paying to Treat Water You Never Sell

Water loss is one of the most frustrating expenses in the industry.

Think about what happens before treated water enters the distribution system.

The utility may have already paid to:

Pump it. Treat it. Disinfect it. Test it. Store it. Pump it again.

Then a leaking main sends that investment into the ground.

Water-loss reduction therefore isn't just a conservation program.

It's a financial-management strategy.

EPA provides specific water-efficiency and water-loss resources for small drinking-water systems and emphasizes tailoring water-loss control programs to individual systems.

Utilities can begin by examining:

Production versus billed consumption
Meter accuracy
Unaccounted-for water
Repeated main breaks
Pressure zones
Storage overflows
Known leak areas
Aging service lines
Large customer meters

Not every gallon of apparent loss represents a physical leak. Meter inaccuracies, accounting errors, unauthorized consumption, and data problems can also contribute.

That's why the first step is understanding where the water is actually going.

Once high-loss areas are identified, repair and replacement projects can be prioritized instead of simply replacing infrastructure based on age alone.

5. Manage Energy Like You Manage Chemicals

Most operators would notice if chemical consumption suddenly increased 25%.

Would someone notice the same increase in electrical consumption?

They should.

EPA recommends establishing an energy-use baseline as an early step toward managing utility energy costs. The agency also provides an Energy Use Assessment Tool specifically intended to help small- and medium-sized systems analyze utility bills, equipment, energy consumption, and costs.

Utilities can examine:

Pump scheduling
Peak electrical demand
HVAC operation
Lighting
Treatment equipment
Building efficiency
Storage-tank operating levels
Well and booster-pump runtimes
Equipment left operating unnecessarily

Sometimes the solution isn't new equipment.

It may simply involve changing when equipment operates.

For example, where operational requirements and electric-rate structures allow it, pumping during lower-cost periods and using storage strategically may reduce costs.

WaterOperator.org has also highlighted energy audits as a way for systems to identify where energy is being consumed and prioritize cost-saving opportunities.

The principle is straightforward:

If you don't measure energy consumption, you can't effectively manage it.

Saving Money Doesn't Mean Cutting Corners

There's an important distinction between cost cutting and optimization.

Cost cutting asks:

"What can we eliminate?"

Optimization asks:

"How can we achieve the same—or better—performance with the resources we already have?"

For water utilities, the second question is far more valuable.

A properly optimized system can potentially:

Reduce chemical consumption
Reduce electricity costs
Extend equipment life
Reduce emergency repairs
Decrease water loss
Improve operational reliability
Strengthen regulatory compliance

And none of those require lowering water-quality standards.

In many cases, better operational control saves money precisely because it improves performance.

The Operator Is Part of the Financial Strategy

Small utilities sometimes view budgeting as something that happens in city hall or the manager's office.

But operators influence utility finances every shift.

Every chemical adjustment, pump selection, equipment inspection, leak report, maintenance decision, and operational change can have a financial impact.

An experienced operator who identifies a failing pump before catastrophic failure may save thousands of dollars.

An operator who recognizes unnecessary chemical feed may save thousands more.

And an operator who notices a developing leak or unusual electrical trend may prevent an even larger expense.

That's why investing in operator knowledge isn't simply a training expense.

It's an operational investment.

The Bottom Line

Small utilities don't necessarily need enormous budgets to become more efficient.

They need good information, good operators, good maintenance, and the willingness to examine how their systems actually perform.

Start with five areas:

Chemical Optimization • Pump Efficiency • Preventive Maintenance • Leak Reduction • Energy Management

Measure what you're doing.

Establish a baseline.

Make one improvement.

Measure again.

Then keep going.

Because ultimately, efficiency isn't about doing less.

It's about getting more value from every dollar while continuing to deliver safe, reliable drinking water to the communities that depend on us.
