Reference material built for the field.
Glossaries, study notes, and technical explainers to support operator education beyond our videos and articles.
Five ways to use the resource library.
Learn, calculate, troubleshoot, study, or download — pick the path that matches what you came here to do and we'll take you straight to the right shelf.
Reference library
Process control, equipment, compliance, and collections reference — eight disciplines, learning paths, and deep technical articles.
Operator math
Detention time, F/M, MCRT, chlorine CT, pumping, and solids loading — every formula operators run on shift.
Process problems
Poor settling, bulking, foaming, nitrification failure, EBPR breakdown, and toxic inhibition — diagnosed.
Certification prep
Practice quizzes, training tiers, formula cheat sheets, and study strategy for state operator certification exams.
Field forms & templates
Confined space permits, LOTO, DMRs, daily rounds, chain of custody, and lift station logs — ready to print.
Wastewater field tools & resources on Amazon
Curated PPE, sampling, process-control, and study gear we actually use — one click to Amazon.

Every operational discipline in the industry, organized in one place. Categories are being filled in continuously — explore what's live today.
Choose a topic to explore.
Process Control
Cheat sheets, glossary terms, and calculations for keeping your plant's biological process in balance.
Equipment Explainers
Field guides to the pumps, blowers, and clarifiers that keep a plant running: how they work and what to watch.
Operator Training
Certification study notes and safety fundamentals to help operators prepare for exams and daily plant work.
Collection Systems
Gravity sewers, manholes, and the inflow/infiltration fight that determines how much of a plant's capacity is spent on clean rainwater.
Lift Stations
Wet wells, pump controls, and force mains: the collection-system stations that move sewage uphill or across long distances.
Pump Stations
Station configuration, redundancy, and standby power planning for larger pumping facilities beyond a standard collection-system lift station.
Laboratory Operations
Sample collection, standard test methods, and the QA/QC program that makes a plant's lab data defensible in an audit.
SCADA & Instrumentation
How PLCs, RTUs, and a central SCADA system work together to monitor and control a plant and its remote stations, and how to keep that system secure.
Asset Management
Inventorying, assessing, and prioritizing capital investment across a utility's pipes, plants, and equipment for the long term.
Energy Management
Where a plant's electricity actually goes, and the operational and capital changes that measurably reduce it.
Water Reuse
Treatment, regulation, and public communication considerations behind turning treated effluent into a reliable, reused water supply.
Leadership for Wastewater Operators
Supervisor and lead operator skills: communication, accountability, and decision-making in a plant that never stops running.
Industrial Pretreatment Programs
Controlling industrial discharges at the source rather than the plant — local limits, permits, and sampling that keep the biology alive.
Electrical Systems at a Wastewater Plant
Reading motor control centers, drives, and protective devices — the electrical vocabulary supervisors and operators need to talk to electricians.
Mechanical Maintenance
Preventive maintenance, lubrication, alignment, and root cause analysis — the work that keeps pumps, blowers, and drives turning year after year.
Wastewater Plant Safety
Confined space, lockout/tagout, hazard communication, and biological hazards — protecting operators in a uniquely hazardous workplace.
Regulations Shaping the Wastewater Industry
Where the rules come from: federal statutes, state primacy, and how the language regulators enforce actually gets written.
Permit Compliance
Reading your NPDES permit, managing DMRs, and staying within the limits — the operator's daily compliance work.
Day-to-Day Operations
How a shift is actually run: rounds, setpoints, sampling cadence, and the logs that prove the plant was operated correctly.
Plant and Utility Management
Budgeting, capital planning, asset strategy, and staff development — the work managers do that operators rarely see but everything depends on.
Emergency Response and Continuity
Power outages, floods, chemical spills, and cyber incidents — the plans, training, and equipment that keep the plant running through the worst day.
Biosolids Management
Stabilization, dewatering, beneficial use, and disposal — turning the unwanted solid fraction into a regulated, manageable product.
Odor Control
Identifying odor sources, ranking them by impact, and choosing control methods that match the actual chemistry at each location.
Tools & Calculators
Interactive calculators operators can plug their own plant numbers into for an accurate result — dosing, hydraulics, disinfection, and process control.
