Water Treatment and RO Plant Service Management

Water treatment service means filter changes, membrane replacements and plant servicing for homes, offices and industry, repeated across a large installed base. Here is how to run it so no filter change gets missed.

Water treatment businesses, from domestic RO filters to commercial and industrial plants, earn much of their revenue after the sale: filter changes, membrane replacements, sanitisation and plant servicing. The business relies on every unit being serviced on time, and on customers trusting that it was.

Know every unit

Keep a record for each installed unit with:

the customer and site;
type and model (domestic RO, commercial RO, softener, UV system or industrial plant);
serial number and install date;
warranty;
the consumables it takes, meaning which filters and which membrane.

Schedule by interval

Filters are changed at set intervals: every three, six or twelve months depending on the stage and the water quality. You can schedule this in two ways.

Fixed calendar: every six months on the same date, which is easy for customers to remember.
From the last service: 90 days after the last filter change was actually done. This works better when visits slip, because the next one moves too.

Set the schedule per unit and let the visits appear ahead of time. Keep an eye on the overdue list, since a missed filter change usually turns into a complaint.

Consumables

Filters, membranes, UV lamps and chemicals are the core of the business. Keep them by location (the warehouse and each van) and record what was fitted on each visit. Van stock stays accurate, and each unit builds a history of the consumables replaced.

A standard visit

A checklist for each visit type keeps the work consistent:

Filters changed (which stages).
Membrane checked or replaced.
Sanitisation done.
Leaks checked.
Water quality tested and the reading noted.
Customer shown the unit working.

Photos of the old filters are an easy way to show the customer why the change was needed.

Commercial and industrial plants

Larger plants need more: regular site visits, chemical dosing checks, and records for the customer's own compliance. If plant components are serviced separately, make each one its own asset.

In Movtro

In Movtro each unit or plant is an asset at the customer's site with model, serial number, install date and warranty, and every visit shows in its history. Recurring jobs schedule filter changes on a fixed calendar or counted from the last completed visit, and flag overdue visits. Filters, membranes and chemicals are held as stock by location, and technicians record what they used on each job. Checklists, photos, notes and the customer's signature are captured on the phone, even without signal.

Water quality readings such as TDS go into the checklist with an allowed range, and results outside it are flagged for review.
