Many water treatment needs are services, not products: someone to design a plant, build it, run it, troubleshoot it or test its output. Services are harder to compare than equipment because the deliverable is partly people and judgement.
The way to make services comparable is to define scope, guarantees and evidence clearly before asking for prices.
What falls under this category
- Studies and design
- Water audits, feasibility studies, process design and detailed engineering.
- Project delivery
- EPC or turnkey contracts, installation, commissioning, upgrades and retrofits.
- Operation and maintenance
- O&M contracts, annual maintenance contracts, operator training and remote monitoring.
- Specialist services
- Membrane cleaning and autopsy, resin analysis, laboratory testing and troubleshooting.
- Alternative models
- Mobile or rental treatment units and build-own-operate arrangements where you buy treated water rather than a plant.
How to evaluate providers
- Relevant references
- Projects with a similar application, capacity and water source, with contacts you can call and, ideally, a site you can visit.
- Defined scope
- Deliverables, exclusions and battery limits (exactly where the provider's scope starts and ends).
- Performance guarantees
- Treated-water quality and quantity, and consumption of power and chemicals, with the test method used to prove them and the remedy if they are missed.
- Service levels
- For O&M: staffing, response times, what spares and consumables are included, and how performance is reported.
- Documentation
- Operation manuals, as-built drawings, piping and instrumentation diagrams, and factory and site acceptance test records.
- Credentials
- Insurance, safety record, licences required locally and staff qualifications.
What to include in your brief
- The problem to be solved and the outcome you need.
- The data you already have, such as water analyses, flow records and drawings.
- Site constraints and access.
- Timeline and preferred contract type.
- How you will compare offers, so providers can address it.
Common sourcing mistakes
- A vague scope that turns into a series of change orders.
- Guarantees with no agreed way of measuring them.
- Choosing the lowest O&M bid without a service-level agreement.
- Accepting handover without as-built documents and operator training.
