A water screen projection site must be evaluated as an optical, hydraulic and show-control system. Confirm the audience and projector geometry, night-time light conditions, wind exposure and maintenance access before specifying screen dimensions or projector output.
Plan the audience, screen and projector together
Begin with a scaled plan showing the intended water-screen position, audience zone, projector position and maintenance route. Identify possible obstructions and the background seen through or around the water. A spectacular reference image does not establish that the same arrangement will work at a different lake or plaza.
Ask the projection designer to check image size, lens choice, throw distance and the intended viewing angles. Rear projection may suit some installations, but it should not be assumed possible without checking the available space and sightlines. Keep the projector location coordinated with public access and equipment protection.
Why do ambient light and wind matter?
Nearby advertising screens, facade lighting and reflected light can reduce perceived image contrast. Record conditions during the actual intended show time, not only during a daytime survey. Where possible, coordinate surrounding lighting scenes with the performance.
Wind can deform or disperse a water screen. Record exposure and agree operating modes, reduction limits and shutdown criteria with the system designer. A wind sensor is useful only when its location, settings and control response match the installation. Do not copy a universal wind-speed limit or projector-lumen figure from an unrelated project.
Site-survey checklist for a projection show
| Topic | Information to record | Design decision |
|---|---|---|
| Audience | Viewing positions, standing or seated use, access and obstructions. | Screen position, image scale and acceptable viewing zone. |
| Water | Depth, level changes, water quality, debris and service access. | Nozzle arrangement, filtration, support and maintenance approach. |
| Optics | Projector position, available throw distance and night-time light. | Lens and projector evaluation under realistic conditions. |
| Environment | Wind exposure, weather, spray drift and sensitive neighbours. | Operating limits, protection and show scheduling. |
| Interfaces | Power, network/control routes, sound system and local approvals. | System boundaries and responsibility assignment. |
Coordinate content and controls
Story development, water effects, video, lighting and audio should share an agreed show sequence. Use the local destination’s story where it genuinely supports the experience; visual content must also suit the water screen’s changing contrast and shape. Test important imagery for readability rather than relying on desktop previews.
Agree programme switching, scheduled operation, equipment start-up, weather response and recovery after an interruption. Confirm which supplier integrates each interface and who can modify programmes after handover. Avoid unverified promises of universal millisecond synchronisation or image correction that removes all water distortion.
How should you judge a demonstration?
- Observe from the intended audience area, with representative surrounding lighting.
- Record the weather and operating mode so the demonstration can be interpreted fairly.
- Use representative show content, including the imagery that matters most to the owner.
- Check normal start-up, programme changes, weather response and a safe controlled stop.
- Inspect the daytime appearance and access for cleaning, alignment and replacement.
Write acceptance conditions into the specification. A video taken from one flattering angle is not a substitute for an agreed site test.
Review a water-screen reference before specifying equipment
Use the wind and weather planning guide to define the operating response.
