These are real pages from the book. The table of contents is the full one: 11 parts and 62 topics.
You've read the treatment train chapter three times. You close the manual...
...and you're not sure anymore if rapid mix comes before floc, or where the chlorine goes. It was just lines of text.
Here the whole plant is one drawing, left to right: intake, rapid mix, floc, settling, filters, chlorine, clearwell and distribution.
And on the pages around it, every process gets its own: the jar test, the gravity filter, breakpoint chlorination, the centrifugal pump and the sample bottle.
First you understand why it's done that way. Then the order sticks on its own.
The exam, source water, coagulation and settling, filtration, disinfection, specialized treatment, equipment, the lab, regulations and safety, water math and a final review: 66 pages, all drawn
Picture this:
Instead of rereading half a page on backwashing without being able to see it...
...you open the page and find the same gravity filter drawn twice: water flowing down in service, and up in backwash.
And coagulation, the jar test, breakpoint chlorination, CT and the pounds formula become drawings and tables you can read at a glance.
You stop repeating and start understanding.
That's exactly what The Water Treatment Operator Sketchbook does. It's not “just another manual.” It's 11 parts and 62 drawn topics, and at the end the frequent mix-ups, formula table drills and an exam day checklist. Because what your brain sees in order, it remembers.
Because what your brain sees organized, it remembers.
Know exactly what you're walking into: Class I vs Class II, WPI (ABC) exams vs state exams, the content areas and question counts, and how to use the formula/conversion table.
The water cycle, surface water and intakes, wells and drawdown, source water contaminants and protection, and hardness, alkalinity and pH basics.
The conventional treatment train, screening and aeration, coagulants and rapid mix, the jar test step by step, floc formation, and sedimentation, tube settlers and sludge.
How granular media filters work, filter runs and head loss, backwash and surface wash, turbidity limits, membrane, slow sand and pressure filters, and backwash water handling.
Free and combined chlorine, breakpoint chlorination, CT and log inactivation, chloramines, ozone, UV and chlorine dioxide, DBPs and MRDLs, and hypochlorite and gas feed systems.
Iron and manganese removal, corrosion control and the LSI, softening and ion exchange, fluoridation, and taste, odor and algae control.
Centrifugal pumps and pump curves, motors and horsepower, valves and backflow prevention, feed pump calibration, meters and analyzers, SCADA, and generators and work orders.
Sampling and chain of custody, pH, alkalinity and hardness tests, turbidity and chlorine residual, coliform and E. coli, iron, manganese, color and odor, and lab safety.
The Safe Drinking Water Act and MCLs, the surface water treatment rules, the Revised Total Coliform Rule, lead and copper, public notification, chemical safety, confined space and lockout/tagout.
Units and constants, area, volume and detention time, flow and pressure, the pounds formula, feed pump settings, filter loading and backwash rates, and dilution, all in the same 4 steps.
The most frequent mix-ups, formula table drills and an exam day checklist.
At the end of the book: Frequent mix-ups, formula table drills and an exam day checklist.
Practice area, volume, detention time, flow, the pounds formula, feed pump settings, filter loading and dilution until you solve them the same way every time.
Review the vocabulary in short sessions: the term on the front, a one-line definition and a tiny sketch on the back, ready to print.

You're coming from another line of work and the CSUS manual reads like a wall of text. Here you see the plant first, from intake to clearwell, one drawing at a time.
A review of every Class I-II content area, one topic per page, plus water math solved the same way every time: data, units, formula, result.
You run the filters and log the residuals every shift. Now you see them on paper, drawn, to go from Class I to Class II and review before your shift.

For operators in training, plant staff going from Class I to Class II, people changing careers and anyone retaking the exam. Each page starts with the drawing, so it works if you're new, and then goes to the operator detail and the math, so it works if you already run the plant. It covers drinking water treatment Class I-II only: not wastewater, not distribution. Check the table of contents above to see every topic.
On the WPI (formerly ABC) Need-to-Know Criteria for Water Treatment Class I and II (2025) and the WPI Formula/Conversion Table (2024), the current eCFR text of 40 CFR Parts 141 and 143, epa.gov, and the California State Water Board Expected Range of Knowledge (Rev. 4/2020). Every MCL is cited with its 40 CFR section. Lead is shown with both values: 15 ppb in the rule as codified on July 1, 2020, and 0.010 mg/L, with compliance no later than November 1, 2027.
No. It's not affiliated with or endorsed by WPI, ABC, EPA or any state program, and it doesn't reproduce exam questions. Many states use the WPI (ABC) Class I-II exams, and the book follows their Need-to-Know Criteria and formula table. California builds its own T1/T2 exam with its own formula sheet, and the book also follows the California Expected Range of Knowledge. Check your state's program to confirm which exam and formula sheet you'll get.
No. It's a visual study aid: it doesn't give a certificate, CEUs or training hours. It doesn't replace state-approved training, on-the-job training, your plant's SOPs or your supervisor's instructions.
No. The 40 problems in the Water Math Workbook, the formula table drills in Part 11 and the optional practice sets offered at checkout are all written for this book. They're not official exam questions: they're there to help you practice.
Yes. The PDF is high resolution, so you can print the whole book or just the pages you want to keep on hand at the plant.
You have a 30-day guarantee: tell us what didn't work and we'll refund 100%.
You don't have to reread the same page hoping it sticks this time.
You don't have to memorize processes you can't picture.
And you definitely don't have to walk into the exam not knowing where to start.
There's an easier way. And it's one click away. Now it's your turn.
