Free course · SCADA
Water and Wastewater Treatment Plant Automation
How drinking water, wastewater and desalination plants are measured and controlled: the process trains, level, flow and water quality instruments, pump station duty and standby logic, VFDs and pump protection, coagulant and chlorine dosing, filter backwash sequences, RO train control, dissolved oxygen and blower control, SCADA, telemetry and alarms, cybersecurity and compliance data, ending with a pump station control narrative.
Free to learn. Verifiable certificate £19 when you pass the final exam (optional, VAT included).

Outcome
What you will be able to do
Draw the process train of a drinking water plant, a wastewater plant and an RO desalination plant and name the instruments and control loops on each; scale level and flow signals and convert weir heads to flow; choose and calibrate pH, turbidity, chlorine and dissolved oxygen analysers and work out sample lag; set wet well levels, size the effective volume and write duty, standby, assist and alternation logic; apply the affinity laws, static head and pump protections to VFD-driven pumps; size flow-paced coagulant and chlorine dosing and check CT; write a filter backwash sequence with its permissives and turbidity triggers; control an RO train and decide when to clean from normalized data; control dissolved oxygen with a cascade and most-open-valve logic and set RAS and WAS from SRT; design telemetry, alarms and secure remote access; and write a control narrative, I/O list and test plan for a pump station.
- Draw water, wastewater and RO process trains with their instruments and control loops
- Choose level, open channel flow and water quality instruments, scale signals and allow for sample lag
- Set wet well levels and write duty, assist, standby, alternation and fail-over logic
- Apply affinity laws, static head, VFD limits and pump protections, and track kWh per m³
- Size flow-paced coagulant and chlorine dosing, check CT and write a filter backwash sequence
- Control an RO train and decide when to clean from normalized data
- Control dissolved oxygen with a cascade and most-open-valve logic, and set RAS and WAS from SRT
- Design telemetry, alarms and secure remote access, and write a control narrative, I/O list and SAT
Software
None is required. A spreadsheet (LibreOffice Calc is free) is used for the calculations, and any PLC or SCADA software you already use (for example Ignition Maker Edition or CODESYS) can be used to try the pump station logic, but every exercise can be done on paper.
Hardware
None. Any laptop that runs a spreadsheet is enough.

EDWartens Lab
Practise this in the EDWartens Lab
Run a tank and pump process in the Lab, read the trends and check alarms the way an operator screen would show them.
Works alongside Water and Wastewater Treatment Plant Automation. The Lab is process control practice in your browser: no install, no hardware, free to use. Sign in as a learner and it opens with your account.

Why practise in a lab
Technical work is judged on what you can do: wiring, commissioning, finding a fault. Doing a task yourself teaches more than watching it a second time, and a lab lets you try it safely before you meet real equipment. It does not replace working on real hardware.
- Practise safely, so a mistake costs nothing.
- The lab checks your work like a site test, so you know when it is right.
- Free, in your browser, with nothing to install.
Certificate
An optional certificate when you pass
Learning is free. Pass the final exam and you can have a certificate for £19, including VAT, with a number employers can check online. It records that you completed a free online course; it is not a regulated qualification or a CPD certificate.
- Your name, the course, its study time and your final exam score
- A unique certificate number and a QR code to its verification page
- Issued by Wartens Ltd; add it to your LinkedIn profile in one click
- Pay now or after you pass: it is issued the moment you pass the final
