The water requirements for linen washing, hot water, and drinking water cannot be merged into one set of criteria. Consult the instructions for each piece of equipment first, then check raw water, hardness, demand, and site service scope.
Build a requirements sheet for each water-use stage
Laundry equipment, hot-water equipment, and drinking-water points have different uses. Organize their individual feedwater requirements, daily volumes, peaks, and operating hours. List testing and management for the drinking-water system separately. Water treated for other stages cannot automatically be classified as drinking water.
Check raw water and regeneration for a softening proposal
For stages requiring hardness control, first confirm raw-water tests, target requirements, and continuous-supply arrangements, then discuss resin, controls, and regeneration provisions. If an existing hot-water system develops scale, also check temperature, makeup water, and maintenance history. A “descaling product” name cannot support a promise to restore all equipment performance.
Include long-term management in the handover
Confirm who is responsible for salt replenishment, inspections, sampling, abnormal-condition contacts, and shutdown arrangements. Proposal comparisons should include storage, piping, drainage, site coordination, and maintenance scope. Without measurements and records under the same conditions, do not advertise fixed percentages for water savings, salt savings, or reduced energy consumption.
Documents to prepare
| Item to check | Information or records | Confirm the application |
|---|---|---|
| Laundry | Equipment instructions, hardness, and operating shifts | Check treatment and regeneration |
| Hot water | Makeup-water volume, temperature conditions, and maintenance records | Define the makeup-water task |
| Handover | Personnel, testing, abnormal conditions, and expense scope | Support ongoing management |
