For a water treatment enquiry in Yunnan, prepare the actual location, water sample information, intended use, demand and interfaces. Regional names help organise enquiry documents. They do not establish local water quality, a branch office, a completed project or a fixed on-site response commitment.
Five document groups for every region
| Document group | Information to provide |
|---|---|
| Project location | Actual location, equipment room, transport and installation conditions |
| Source and testing | Water source, sampling point, date, method and laboratory report |
| Use and demand | Process, cleaning, domestic or cultivation use; daily demand and hourly peaks |
| Equipment and interfaces | Actual models, pipe sizes, power, drainage and modification scope |
| Handover and services | Responsibilities for supply, installation, commissioning, maintenance and acceptance; confirm costs and dates for the particular project in writing |
Kunming: factory, building and cultivation interfaces
State the project location and separate process, cleaning and domestic water requirements.
- RO membrane maintenance and replacement checklist
- Thin-wall stainless steel press-fit piping: standards and compatibility
Qujing: different water quality tasks in production
Match each production step with its water quality requirements, operating hours and measurement points. An industry name alone does not determine the treatment process.
- EDI handover: feedwater, measuring points and start-up interlocks
- Comparing RO recovery: water balance, concentrate and operating costs
Yuxi: cultivation samples and existing equipment records
Identify the raw water, treated blending water and nutrient solution sampling points. Cultivation and production water require separate acceptance objectives.
- Source-water testing for soilless cultivation: what EC, pH and alkalinity tell you
- UF integrity checks: what online readings and direct tests show
Dali: multiple uses and pipework changes
Separate drinking, business and production water requirements. Provide actual interfaces for pipework modifications; the premises type alone does not establish drinking water suitability.
- Does low TDS mean drinking water is safe? Define the tests first
- Thin-wall stainless steel press-fit piping: standards and compatibility
Honghe: irrigation zones and peak demand
Record each irrigation zone, its area, operating schedule and storage arrangements. Add the measurement point and sampling time to EC and pH readings.
- Source-water testing for soilless cultivation: what EC, pH and alkalinity tell you
- Comparing RO recovery: water balance, concentrate and operating costs
Lijiang: multiple consumption points and the pump room
List hourly peak demand and storage needs for multiple consumption points. Confirm the project location and pump room layout from site information.
- High-altitude pump selection: location, temperature and suction layout
- Does low TDS mean drinking water is safe? Define the tests first
Diqing: actual location and minimum water level
Provide the actual project location, water temperature range and minimum operating water level. The prefecture name does not replace checks of pressure conditions or equipment suitability.
- High-altitude pump selection: location, temperature and suction layout
- RO membrane maintenance and replacement checklist
Zhaotong: operating hours and usable output
Record operating hours, usable water demand and flushing water separately. Daily output alone is insufficient for comparing quotations.
- Comparing RO recovery: water balance, concentrate and operating costs
- RO membrane maintenance and replacement checklist
Baoshan: consumable replacement and component traceability
Prepare full membrane and cartridge models, quantities, batches and records before and after replacement. Mark details that photographs cannot establish as awaiting confirmation.
- UF integrity checks: what online readings and direct tests show
- Thin-wall stainless steel press-fit piping: standards and compatibility
Chuxiong: equipment interfaces and modification scope
Provide existing interfaces, dimensions and the proposed modification scope. Check documents for pipes, fittings and seals separately.
- Thin-wall stainless steel press-fit piping: standards and compatibility
- EDI handover: feedwater, measuring points and start-up interlocks
Wenshan: separate raw water information from the intended use
State the source, test date and intended use of the water. Keep testing objectives and delivery agreements separate for different uses.
- Does low TDS mean drinking water is safe? Define the tests first
- Source-water testing for soilless cultivation: what EC, pH and alkalinity tell you
Xishuangbanna: irrigation zones and filtration handover
Mark cultivation zones and the filtration-to-irrigation handover points on the site documents. Do not infer local raw water characteristics before testing.
- Source-water testing for soilless cultivation: what EC, pH and alkalinity tell you
- UF integrity checks: what online readings and direct tests show
Puer: sampling points for processing, cleaning and drinking
List processing, cleaning and drinking water tasks and sampling points separately. A TDS reading cannot replace verification for each intended use.
- Does low TDS mean drinking water is safe? Define the tests first
- Comparing RO recovery: water balance, concentrate and operating costs
Lincang: fault history and maintenance evidence
Keep the time of the fault, readings, actions taken and retest results. Data obtained after adjustments should not replace the original fault evidence.
- RO membrane maintenance and replacement checklist
- UF integrity checks: what online readings and direct tests show
Dehong: procurement lists and change records
Match equipment and fittings with full models or fields awaiting confirmation. Record substitutions and procurement list changes individually.
- Thin-wall stainless steel press-fit piping: standards and compatibility
- EDI handover: feedwater, measuring points and start-up interlocks
Nujiang: site location and delivery access
Provide the actual location, pump room and transport or installation conditions. Review the documents remotely before confirming supply and site services.
- High-altitude pump selection: location, temperature and suction layout
- Comparing RO recovery: water balance, concentrate and operating costs
Using the documents
Review equipment and consumable requirements remotely before confirming supply, installation or site services against actual conditions. Mark missing models, test items and interfaces as awaiting confirmation. Do not replace them with assumptions about the region or equipment appearance. Confirm applicable requirements separately for drinking, industrial and cultivation uses.
