Define this task first
Specify uses for cultivation and production water first
For soilless cultivation, describe the crop, nutrient solution, and reuse arrangements. For production, provide process requirements. Testing and selection cannot be determined solely by an equipment name or project location.
At which stages is the same water used, and do their requirements differ?
What EC, pH, and alkalinity each represent
EC reflects overall electrical conductivity and cannot alone establish the composition of individual ions. pH and alkalinity are also different parameters. When testing, clearly identify the water sample source, sampling time, and units. Add relevant parameters according to actual water preparation and management requirements. Do not determine the entire process from one EC value.
Check the source of clogging before selecting filtration upstream of drip irrigation
Describe the water source, piping, emitter specifications, existing filtration stages, and abnormal symptoms. Sediment, deposits, and other causes need separate assessment. Filters, ultrafiltration, softening, and RO have different treatment duties. Do not assume every drip irrigation blockage can be solved by one type of equipment.
Confirm nutrient solution water preparation together with supply timing
Record the water quantity for each preparation, preparation frequency, peak irrigation periods, and storage and reuse arrangements. Agree verification of treated water quality separately from nutrient solution formulation adjustments. Do not treat the main unit's flow rate or outlet conductivity as evidence of crop yield or quality.
Describe irrigation water and nutrient solution conveyance separately
For thin-wall stainless steel water pipe requirements involving cultivation in Yuxi, distinguish raw water, treated water, nutrient solution, and return water. Press-fit fitting provision in Yuxi requires checks of the fluids in contact with the fittings and cleaning arrangements. Design and product documents determine whether stainless steel is used and which grade applies. Pipe selection does not imply increased yield or guaranteed crop results.
Label raw water, prepared solution and return solution separately
If the project involves fertigation or soilless cultivation, assign separate identifiers to raw water, treated water, prepared nutrient solution and return solution. Record sampling time, temperature, EC units, pH and instrument calibration. EC provides information related to the electrical conductivity of dissolved salts; it does not identify individual salts, nutrient balance or pathogen risk on its own. Neither pH nor alkalinity substitutes for the other. The cultivation lead should record fertilizer addition order, crop stage and return proportion separately so that anomalies can be traced across treatment, solution preparation and irrigation management.
Cultivation projects in Yuxi: connect water analysis with irrigation zoning
Match the water-quality records to the actual source and the supply records to each irrigation zone. List the zones operating together, emitter or sprinkler documents, and normal-filtration and backwash conditions. For water preparation, also provide raw-water EC, pH, alkalinity and relevant ion tests. Confirm filtration requirements and fertilizer-management targets separately.
Pipe and fitting integration information
Display of pipes, basic press-fit components, and threaded/flange adapters. Check specifications, connections, and supply responsibilities for the actual use.

Information to bring to this discussion
The table below can serve as a checklist for this inquiry. Mark unavailable information "pending confirmation" and distinguish estimates from measured records. Do not upload identity documents, customer lists, or internal confidential materials.
| Discussion item | Information to prepare | Confirmation needed |
|---|---|---|
| Test samples | Raw water, treated water, nutrient solution, or return water | Sample name and sampling time |
| Irrigation system | Emitters, piping, filtration, and clogging records | Treatment duties and filtration requirements |
| Water preparation schedule | Quantity per preparation, frequency, storage, and reuse | Actual supply capacity and management responsibilities |
| Fluids and cleaning | Whether water or nutrient solution is conveyed, cleaning chemical information, and reuse arrangements | Suitability of materials and seals for the actual fluid |
| Solution measurement-point identifiers | Identifiers for four sample types, time, temperature, EC units, pH and calibration records | How treatment and cultivation leads jointly trace an abnormal batch |
Expand the general inquiry and delivery checklist
- 01Project location
- Prefecture or city, district or county, intake point, equipment installation location, and whether different locations are involved. Do not upload identity documents or customer lists for an initial inquiry.
- 02Water source and testing
- Tap water, well water, surface water, or other sources; record sampling points, dates, testing organizations, and the report's applicable scope. Do not infer water quality from a city name.
- 03Treated-water use
- Production, cleaning, cultivation, drip irrigation, or other uses; provide the corresponding process, crop, or actual usage requirements. Acceptance requirements may differ by use.
- 04Demand and schedule
- Daily demand, peak hourly demand, permitted operating time, and storage arrangements. Mark values for confirmation when measured data are unavailable. Estimates must not be recorded as equipment guarantees.
- 05Equipment and site
- Existing equipment models, consumable specifications, power supply, space, drainage, operating environment, and site-access conditions. Equipment photos should avoid capturing personal or confidential information.
- 06Budget and delivery
- Specify the budget, supply list, transportation, unloading, installation, commissioning, acceptance, and after-sales scope. Timing and expenses are governed by the confirmations for this project.
- 07Plateau site and water temperature
- Actual installation altitude, seasonal feed-water temperatures, pump inlet pressure or water level, suction piping and power; review the specific model. Altitude is not a water-quality test.
- 08Sampling points and operating baseline
- Sampling locations, dates, units, temperature compensation, and normal and abnormal records. Keep raw water, treated water, nutrient solution and return water separate.
