From need to process train
Flow, pollution load, variation, footprint, energy, sludge, maintenance and discharge or reuse requirements guide the solution.
10Engineering & Infrastructure
Water, wastewater and nature-based treatment
Treat, reuse and preserve water through a process matched to influent quality and final use.
Characterise. Treat. Secure. Reuse where appropriate.
A/01
Design principle
Data • Interfaces • Evidence
What water quality is required, for which use and with what level of control?
01Wastewater and greywater treatment
02Biological, physical and physico-chemical processes
03Constructed wetlands and planted filters
04Reuse for irrigation or technical purposes
05Sustainable stormwater management
06Analytical monitoring and health protection
Natural or intensive systems
Constructed wetlands, compact biological processes and advanced treatment may be combined.
Controlled reuse
Any reuse, especially potable reuse, depends on analysis, multiple barriers, continuous monitoring and applicable health requirements.
Assignment method
From observation to performance evidence.
The approach maintains continuity from diagnosis and design through delivery and operation.
Measure influent flow and quality
Define discharge or final use
Compare natural and intensive processes
Design barriers, sludge and control
Commission and monitor quality
Deliverables
Documents designed to decide, procure, control and operate.
A deliverable is not a formality: it organises assumptions, responsibilities, interfaces and required evidence.
Characterisation campaign and pollution balance
Multi-criteria process comparison
Hydraulic diagrams, equipment and civil works
Analytical, operation, safety and sludge plan
Typical assignment — method illustrationApplied scenario
A response built around the real problem.
- Situation
- A site seeks to treat effluent and is considering reuse.
- ANTA response
- Influent, variability, footprint, energy, skills, risks and final use define the process.
- Expected outcome
- A process that is suitable, controllable and fit for purpose.
This scenario illustrates a working method; it is neither a client reference nor a performance commitment without a study.
Interfaces
No lasting performance is designed in isolation.
Disciplines are connected to control transfers of load, energy, water, air, data and responsibility.
