When On-Site Training Pays for Itself: A Real-World Jar Testing Example
How Jar Testing saved thousands:
One of the most common challenges we see at small and mid-sized water treatment plants is chemical dosing that feels more reactive than controlled. Operators know something isn’t quite right, but without time, tools, or confidence to troubleshoot, small inefficiencies can quietly turn into big costs.
Recently, WtrWrx Services worked with an Illinois community water treatment plant facing exactly this situation.
Rather than delivering a classroom-style presentation, we provided on-site, facility-specific training focused on jar testing and chemical dosing, using the plant’s actual source water, treatment chemicals, and equipment.
Training Using the Plant’s Own Water and Chemistry
During the on-site session, operators walked through:
How to properly set up and run jar tests
What to look for when results don’t match expectations
How to troubleshoot dosing issues using visual and performance indicators
How to translate jar test results into confident, real-world dosing adjustments
Because the training was conducted with the facility’s own water and chemicals, the results were immediately relevant. Operators weren’t learning theory—they were solving their own process challenges in real time.
Immediate Results and Long-Term Savings
By the end of the training, the operations team was able to:
Identify inefficiencies in their existing chemical dosing approach
Make informed adjustments based on jar testing results
Establish a repeatable process that they could continue using independently
Those changes led to significant annual chemical cost savings, ultimately more than offsetting the cost of the on-site training itself.
Just as importantly, the operators left with greater confidence in their decision-making and a clearer understanding of how to respond when conditions change.
Why Facility-Specific Training Matters
Every treatment plant is different. Source water quality, seasonal variability, treatment goals, and available resources all play a role in how systems perform.
That’s why on-site training can be so effective:
It uses your water, your chemistry, and your equipment
Operators learn by doing, not just listening
Improvements can be implemented immediately
Benefits extend beyond compliance to cost control and system reliability
Training That Supports Operators and Communities
At WtrWrx Services, our goal is to support operators with practical, field-tested solutions that make daily operations easier and more effective. When operators are empowered to make confident treatment decisions, the entire community benefits—from improved water quality to better use of limited resources.
If your system could benefit from on-site training tailored to your facility and your operators, we’re happy to talk about options that fit your needs.
