Define this task first
Check raw water and reuse first for cultivation water
For cultivation or drip-irrigation water inquiries, distinguish raw water, treated water, nutrient solution, and return water first. Organize testing information according to crop and system requirements. Water-treatment equipment cannot replace complete nutrient management.
Is the test sample raw water, nutrient solution, or return water?
Create separate records for raw water and return water
Record each sample's source, sampling point, date, usage stage, and whether it has been treated. Return water has already participated in cultivation and cannot be treated directly as newly drawn raw water. Confirm test items and subsequent arrangements using the actual system and growing-management requirements.
Filtration, water preparation, and reuse are different tasks
Describe the existing configurations for upstream filtration, storage, nutrient-solution preparation, and reuse. Treatment and monitoring needs may differ at each stage. One purification unit cannot directly serve as a complete reuse-management plan. Agree on equipment configuration and growing-management responsibilities separately.
Connect the water-supply schedule with preparation management
Provide crop, irrigation frequency, volume per event, tank, and piping information, and record actual blending and water-use arrangements. Output-water criteria describe only the subject tested. They do not replace verification of nutrient formulations, crop health, or environmental management.
Use consistent drawing versions for phased purchasing
If thin-wall stainless steel water pipes for Xishuangbanna are purchased in stages, retain the drawing version and change records for each order list. For press-fit fittings in Xishuangbanna, check the same series, dimensions, and transition connections at each stage. Confirm transportation, storage, and handover requirements each time. Do not assume different batches are automatically compatible.
Specify filtration and disinfection tasks for cultivation return water separately
If the project uses return water, map collection, storage, filtration, treatment and preparation of the next solution, and keep records of fresh-water additions and return-water discharge. Particle filtration, reduction of dissolved salts and pathogen control are different tasks; installing UF or RO does not remove the need for relevant verification. The cultivation and treatment leads should set monitoring points, cleaning, sampling and reuse decisions using the actual crop, return-water analysis and equipment conditions. No universal regional recipe is prescribed.
Cultivation-water reuse in Xishuangbanna: separate raw-water and return-water files
For nutrient-solution return or other reused water, identify its source, mixing status, collection point, tests and management targets. Review raw-water pretreatment, return-water treatment and nutrient adjustment separately. The presence of RO, UF or a filter does not establish that reused water is suitable for crops or safe for human drinking.
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 |
|---|---|---|
| Water sample subject | Raw water, treated water, nutrient solution, and return water | Match sampling and testing to each subject separately |
| System stages | Filtration, storage, preparation, and reuse processes | Treatment tasks and responsibility scope |
| Operating arrangements | Crop, frequency, demand, and blending records | Whether equipment supply matches management requirements |
| Phased provisions | Drawing versions, quantities by stage, previously purchased series, and change records | Compatibility of subsequent batches and handover scope |
| Return-water treatment path | Collection and reuse diagram, make-up and discharge records, sampling points and cleaning records | How particles, salts and pathogen-control tasks are verified separately, and who decides on reuse |
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.
