Complete the blank project-value column and share the file with your enquiry. This is a planning worksheet, not an equipment specification.
| Parameter / interface | Unit / format | Why it matters |
|---|---|---|
| Average / maximum daily flow | m³/day | Provide both values with the measurement or estimation basis. |
| Peak hourly inflow | m³/h and duration | Describe morning, evening and intermittent discharge peaks. |
| BOD₅ / COD / TSS | mg/L | Attach laboratory results with sampling date and location. |
| Nitrogen / phosphorus / pH | mg/L; pH | Identify the parameters required by the project treatment target. |
| Wastewater temperature / occupancy | °C; seasonal profile | Describe cold conditions and periods of low or zero loading. |
| Effluent target and sampling point | Project requirement | Attach the project limits and define how acceptance is measured. |
| Sludge route / site utilities | Site plan and responsibility | Identify disposal access, electrical supply and civil-work boundaries. |
