Dry fountains, also known as invisible fountains, feature no exposed water basins; the surface is walkable; all equipment is fully buried underground; they drain quickly; operate at low pressure for safety; and support interactive features. They are widely used in public spaces such as municipal plazas, commercial plazas, and recreational parks.

I. Preliminary Survey and Requirements Confirmation
1. Site Survey: Verify ground load-bearing capacity, foot traffic volume, ground levelness, and underground utilities to avoid construction conflicts.
2. Functional Definition: Determine modes such as standard landscape, music, motion sensing, and children’s interactive modes; confirm spray height, performance styles, and activation/deactivation methods (timed / sensor-activated / manual).
3. Parameter Confirmation: Standard spray height ≤ 1.5 m; confirm drainage slope, excavation depth, paving style, and winter freeze protection requirements.
4. Water and Electricity Verification: Confirm low-voltage power supply, grounding conditions, and the layout of water supply and drainage networks.

Many people only see how spectacular the water screen show is, but fail to realize just how meticulous the setup process is behind the scenes. Let’s get straight to the point—we generally follow these 7 steps to set up a light and water screen projection show.

Step 1 On-Site Reconnaissance + Layout and Positioning The design drawings do not necessarily match the actual site. The first thing to do upon arrival is to conduct an on-site reconnaissance using the drawings: verify the water boundaries, water depth, power supply points, control room location, and audience area—check everything on-site. Then, lay out and mark the positions—nozzle arrays, floating anchor points, projector positions, and lighting positions—using GPS or a total station to achieve millimeter-level accuracy. If this step is done incorrectly, everything that follows will be off.

Step 2: Foundation and Utility Connections First, pour or assemble the foundations for the onshore control room and power distribution cabinets; simultaneously, pre-install underwater and shoreline cable trenches, as well as water supply and drainage pipes. Allow ample power capacity (as the peak power consumption of pumps, projectors, and lighting combined is significant), and install independent grounding and lightning protection. This step represents the “invisible foundation” of the project.

Step 3: On-Site Assembly of Modular Equipment This is the core advantage of the source factory: nozzles, pump assemblies, valve assemblies, and control cabinets are prefabricated, pressure-tested, and aged-tested at the factory; upon arrival, they are “modules,” not “parts.” The above-water components are assembled using modular floats or fixed steel brackets, while shore-based equipment is mounted on racks in the control room. On-site assembly involves assembling like building blocks, not on-the-spot welding or splicing.

Step 4: Pipeline Installation and System Wiring. Water supply and return pipes are spliced, sealed, and pressure-tested; power cables and control buses (DMX/network) are routed in separate conduits, with high- and low-voltage circuits isolated. All underwater joints are waterproofed and double-sealed. Each circuit is numbered and tagged for easy identification during future operation and maintenance.

Step 5 Individual Component Commissioning (Three Separate Tasks) ① Water Pattern Calibration: Adjust the angle and flow rate of each nozzle individually to ensure the water curtain is as smooth as a mirror and the spray height is consistent. ② Projector Focus: Adjust the camera position, focal length, and trapezoidal correction to ensure the image is distortion-free and color-accurate. ③ Lighting Programming: Program the underwater RGB lights, lasers, and wall-washing lights frame by frame according to the scene breakdown. Ensure each component functions independently before proceeding to synchronized testing.

Step 6 Synchronized Rehearsal: As the music plays, synchronize the five elements—water, screen, lighting, projection, and sound. Start with a slow playback to identify the beat, then run at full speed, repeating the process at least three times: check if the water patterns keep pace with the drumbeat, if the projection is obscured by water mist, and if the lighting is overpowering the visuals. All issues will be exposed and resolved during this step.

Step 7: Acceptance, Delivery, and Operations Handover—Prepare a debugging report, operating manual, and emergency response plan; train the client’s staff on startup, shutdown, and daily inspections; set up a remote maintenance channel so that adding holiday programs or performing component upgrades can be handled with a single phone call. Delivery isn’t the end—it’s the beginning of long-term support.

Many clients approach us and say, “I want to build a fountain, and my budget is roughly this much.”

01 First, figure out: Who is this fountain for?

The first step in design isn’t selecting nozzles—it’s defining the concept. Different plazas require vastly different pool sizes, nozzle types, and control systems:

City Landmark Plazas—They need to be awe-inspiring and photogenic. Musical fountains and large-span water curtains are the mainstream choices, complemented by lighting for nighttime displays.

Commercial Complexes—The goal is to attract crowds and drive foot traffic. Interactive dry fountains and jumping fountains are ideal; children love to play with them, and young people love to take photos.

Residential Communities / Parks — Safety is the top priority; quiet, small fountains or low water features are sufficient, and water depth must be kept to a minimum.

If the positioning isn’t nailed down from the start, the entire project will end up requiring rework. I’ve seen many projects where government plazas were built on a commercial plaza budget, resulting in fountains that looked like showers; conversely, commercial plazas were designed as if they were landmark plazas, leading to unsustainable maintenance costs and eventual shutdowns.

02 Hard Requirements for Pool Design (Major Pitfalls)

The pool is the “foundation” of a fountain; if the foundation is flawed, even the best equipment is useless.

Water Depth: Pools for purely aesthetic purposes are generally 0.3–0.6 m deep; children’s interactive areas should be even shallower and must feature non-slip surfaces and rounded edges; dry fountain areas must ensure no water accumulation and no tripping hazards.

Pool Structure: Reinforced concrete pool walls + flexible waterproofing membrane (SBS or polyurethane). Don’t trust “brick-built with a coat of waterproofing paint”—it’s bound to crack within six months.

Circulation and Filtration: The water that’s sprayed out must be recirculated. A circulation pump and filtration system are mandatory; otherwise, the water will turn green within a week and become a mosquito breeding ground in the summer.

Electrical Safety: Underwater lights and pumps must meet IP68 waterproofing standards and be equipped with ground fault circuit interrupters (GFCIs) and equipotential bonding. This is a red line—not an optional requirement.

Overflow and Drainage: The system must be able to overflow and drain during heavy rain and be quickly drained for maintenance; otherwise, the pool will turn into a reservoir the moment it rains heavily.
