# Supplies & Procurement — Water Treatment

Specify, source and manage the supplies and materials used in treatment works and pumping stations. The deliverable is a procurement list with specifications, stock levels and supplier checks.
This skill is written for a water treatment operator working with the public, via water companies in treatment works and pumping stations.

## When to use
- You are a water treatment operator preparing, delivering or reviewing this part of your work in treatment works and pumping stations.
- You need a defensible, repeatable approach that produces a procurement list with specifications, stock levels and supplier checks.
- A colleague, auditor or client asks how this was done and what evidence supports it.

## Key Concepts
| Term | Meaning |
|------|---------|
| Coagulation | a treatment stage clumping fine particles for removal |
| Turbidity | the cloudiness of water from suspended particles |
| Consent limits | legal limits on what treated water must achieve |

## Workflow
1. **Step 1** - List what the work consumes, drawing on process logs and the kit centred on treatment plant systems, with exact specifications
2. **Step 2** - Set minimum stock levels from usage rates and lead times so work never stalls waiting for supplies
3. **Step 3** - Compare suppliers on quality, reliability and total cost — not unit price alone — and check credentials
4. **Step 4** - Receive and inspect deliveries; reject or quarantine substandard stock before it can contribute to contamination reaching supply
5. **Step 5** - Track usage and waste monthly; adjust order quantities and challenge specifications that no longer fit

## Profession-Specific Components
| Component | Details for Water Treatment |
|-----------|-------------------------------|
| Core documentation | process logs; sample results; maintenance records; incident reports |
| Core tools & equipment | treatment plant systems; laboratory equipment; dosing pumps; SCADA monitoring |
| People involved | the public, via water companies; the water treatment operator; colleagues and other services in treatment works and pumping stations |
| Primary record | process logs — keep it current, dated and attributable |

## Output Format
**Context:** [Situation in treatment works and pumping stations] | **Objective:** [What this must achieve] | **Audience:** [the public, via water companies and other stakeholders]

The finished output is a procurement list with specifications, stock levels and supplier checks, structured as:
1. Summary of position and evidence
2. Detail, following the workflow above
3. Decisions, actions, owners and dates
4. Review point and escalation route

### Action Plan
1. **Immediate:** Confirm scope, consent and the evidence available in process logs.
2. **Short-term:** Complete the workflow steps and record outcomes against water quality compliance.
3. **Medium-term:** Review results, close actions, and update local procedures in treatment works and pumping stations.

## Success Metrics
| Metric | Target | Method |
|--------|--------|--------|
| water quality compliance | Agree a local target and track the trend | Measured from process logs and reviewed on a set cycle |
| process efficiency | Agree a local target and track the trend | Measured from process logs and reviewed on a set cycle |
| sample pass rates | Agree a local target and track the trend | Measured from process logs and reviewed on a set cycle |
| response to alarms | Agree a local target and track the trend | Measured from process logs and reviewed on a set cycle |

## Guardrails & Quality Checks
- Never let this happen: contamination reaching supply.
- Never let this happen: chemical dosing errors.
- Never let this happen: process failures.
- Work only within the competence and authority of a water treatment operator; escalate or refer anything beyond it.
- Record facts and observations, not speculation, and keep records confidential to treatment works and pumping stations's rules.
- Verify names, dates, figures and measurements twice before anything is issued or signed off.
- Use only real, verified information from the case in hand — never invent results, credentials or evidence.

## Example (illustrative)
A water treatment operator in treatment works and pumping stations applies this workflow for the public, via water companies: they open
process logs, work through the five steps using treatment plant systems, and close by recording
the outcome against water quality compliance and agreeing the next review date. (Illustrative example only —
replace with the real details of the case in hand.)
