Size production and storage
Estimate rinse litres per job and your refill window. A purification unit’s output is not the same as the instantaneous flow needed by a pressure-washing pump.
RO water. Plan for volume.
Reverse osmosis uses a membrane to separate much of the dissolved mineral load from the water. It can reduce the workload on a final DI stage when producing larger volumes of rinse water.

Storage & wash pump
Illustrative water path; final plumbing and pressure requirements depend on the selected equipment.
Where RO fits.
- Repeat jobs with larger pure-water requirements.
- Source water that would consume DI resin quickly.
- A custom ground rig with space for treatment and storage.
The trade-off
RO adds filters, membrane maintenance and a reject-water stream. Production depends on inlet conditions; plan treatment capacity and buffer storage separately from the wash pump’s flow.
With SF13 or a custom rig
SF13 / HoverWash 13 does not include DI or RO. Specify a separate treated-water supply, or integrate purification and storage into a custom NECSS van or trailer build. A heat box is a separate choice and does not purify water.
Design around the working day.
Plan the water connections
Allow for source-water supply, the treated-water path and reject-water handling. Follow the equipment manufacturer’s inlet and drain requirements.
Build a maintenance routine
Replace pre-filters and service the membrane as specified. Follow the manufacturer’s storage and freeze-protection instructions when the rig is parked.
Check the final rinse
Monitor treated water and the final DI stage where fitted. Confirm the result on a test panel before committing to a full facade.

Compare the other approach.
For smaller demand or lower-TDS water, a simpler DI setup may fit. DI can also polish RO output.
