When Precision Slips, Everything Else Follows
Chemical dosing may seem like a small detail in a water system — but when it’s done wrong, the consequences can be catastrophic.
Unmonitored or mismanaged dosing doesn’t just waste product — it corrodes infrastructure, jeopardizes public health, and can lead to environmental violations that cripple your operations.
Let’s break down the hidden dangers of under- and over-dosing, and how to build a resilient, compliant dosing strategy that protects your system and your people.
What Is Chemical Dosing?
Chemical dosing is the controlled addition of chemicals into a water or wastewater system to achieve treatment goals.
Common agents include:
-
Soda Ash – Adjusts pH and alkalinity
-
Chlorine – Disinfection
-
Phosphates – Protects pipes from corrosion and scale
-
Acids – pH reduction
-
Coagulants – Sediment removal in treatment plants
But these chemicals are only effective when precisely dosed. Anything less invites trouble.
What Happens When Dosing Goes Wrong?
Infrastructure Damage
-
Overdosing soda ash or chlorine can lead to pipe scaling, corrosion, or valve failure
-
Underdosing leaves water chemically unstable, which can erode metallic components over time
Public Health Risks
-
Too much chlorine = disinfection byproducts (DBPs) like trihalomethanes
-
Too little = pathogen risk and potential outbreak
-
Dosing imbalances can also affect taste, odor, and customer trust
Regulatory Penalties
-
Incomplete or missing dosing records? That’s a fast track to audit failure, fines, or shutdowns
-
SWRCB and EPA require clear documentation for chemical usage, calibration, and monitoring
Environmental Harm
-
Overdosed systems can dump chemicals into the environment, harming aquatic life
-
Underdosed wastewater may carry untreated organics or nutrients, triggering violations
Operational Inefficiency
-
Wasted chemicals = wasted money
-
Unstable dosing causes reactive maintenance, downtime, and premature equipment replacement
5 Steps to Smart, Safe Chemical Dosing
1. Monitor & Calibrate Regularly
Install automated dosing pumps with flow-proportional logic and real-time monitoring.
Schedule monthly calibration checks or more frequently for critical systems.
2. Train Staff Thoroughly
All staff handling chemicals should be trained in:
-
Proper mixing and storage
-
Chemical reaction awareness
-
How to interpret dosing data and respond to anomalies
3. Conduct Routine System Inspections
Audit not just the pump — but the entire feed line. Look for scaling, leaks, and signs of corrosion at injection points.
4. Keep Detailed Records
Log:
-
Daily dosing volumes
-
Calibration data
-
Chemical deliveries and inventory
-
Any adjustments or anomalies
This is your lifeline during an inspection or regulatory review.
5. Use Analytics for Optimization
Modern systems let you track chemical trends over time, helping you spot overuse, seasonal shifts, or underperforming equipment before it fails.
