Water curtains are a classic water feature that enhances the ambiance of a space and are widely used in hotel lobbies, commercial atriums, corporate exhibition halls, and private gardens. The key to their design lies in ensuring that the water flows down evenly, quietly, and in a controlled manner.

I. Choosing the Right Type

Overflow Trough Style: Water overflows from a top trough and flows down the facade—the most classic design, suitable for both indoor and outdoor use.

Linear Curtain Style: Water falls vertically from openings without touching the surface, creating a strong sense of transparency; ideal for lobbies and exhibition halls.

Fiber-Optic / Digital Water Curtain: Capable of changing colors or displaying patterns; suitable for commercial and entertainment spaces.

The overflow trough style is the top choice for indoor settings due to its low noise level and simple maintenance.

II. Four Key Parameters

| Parameter | Recommended Value | Notes |

| Water Film Thickness | 2–5 mm | Too thin causes the flow to break; too thick causes splashing |

| Water Flow Velocity | 0.3–0.8 m/s | Too fast causes excessive noise; too slow results in an intermittent flow |

| Overflow Outlet Flatness | Within ±1 mm | If not level, the water flow will be skewed |

| Wall Inclination | 3°–5° (slight slope) | Reduces water splashing |

III. Materials and Structure

Water-bearing Surface: Ultra-clear tempered glass (transparent), stainless steel sheet (modern), natural stone (natural)

Overflow Channel: 304/316 stainless steel, with precision-milled edges at the channel opening; equipped with adjustable feet for leveling

Drainage Channel: ≥200 mm wider than the water-bearing surface; covered with a grating to prevent splashing; filled with river pebbles to dissipate energy and reduce noise

Waterproofing: A complete waterproof layer is applied to the interior back panel; a 50–100 mm ventilation gap is left between the wall and the water curtain

IV. Water Circulation System

Pump: Low-noise centrifugal pump mounted on a vibration-damping foundation, with flexible connections at the inlet and outlet

Filtration: Hair filter + 50–100 mesh bag filter to prevent clogging of the overflow outlet

Water Tank: Capacity of 3–5 times the circulating water volume, equipped with automatic water replenishment, overflow, and drainage

Disinfection: Indoor UV disinfection to suppress algae and odors

Freeze Protection: Outdoor piping insulated with heating cables or designed for winter drainage

V. Lighting and Noise Reduction

Lighting: Concealed LED underwater lights (IP68) at the bottom, illuminating upward; 3000K warm white for a premium look; RGB for dynamic effects

Noise Reduction: Energy-dissipating layer in the water collection trough + pump sound insulation + piping designed to avoid right-angle bends + bottom water-guiding channels

VI. Key Points to Avoid Pitfalls

1. The overflow outlet must be leveled—use a level to calibrate each section during installation

2. Manage water quality—hard water causes scaling, and stagnant water promotes algae growth; plan filtration and disinfection in advance

3. Allow for maintenance access—the pump, filter, and overflow channel must all have accessible covers for maintenance

4. Estimate noise levels in advance—for indoor projects, pay special attention to controlling pump and drainage noise

VII. Design Process

Determine requirements → Select and finalize models → Hydraulic calculations → Structural design → System integration → Construction and installation → Commissioning and maintenance

Musical fountains are one of the few types of purchases where “the pitfalls are already in place before you’ve even spent a dime”—you’re not buying a ready-made product, but rather commissioning a manufacturer to design, produce, program, ship, and install it for you, and to ensure it works properly for several years.

Choose the right manufacturer, and the entire project will go so smoothly it’s almost boring: on time, on budget, and still running normally ten years later.

I. Is It a Manufacturer or a Middleman?
The first thing to clarify: Are you dealing with a manufacturer or a trading company?

Trading companies have no factories, no engineering teams, and no control over quality. They take your deposit, outsource the work to the lowest bidder, mark up the price, and spend the rest of their time forwarding emails. When the pump breaks down and you call them, you’ll be speaking to someone who’s never even held a wrench.

A genuine source factory handles design, machining, assembly, and testing entirely in-house. The benefits are tangible:

You can work directly with the engineers who actually build the equipment.
Quality inspections are conducted at every stage—not just spot checks after the goods arrive.
The warranty is backed by the people who actually manufacture the product.
There are no middleman markups.
How to verify: Ask them to send a live video of the factory workshop, photos of the production line, and a business license showing export qualifications. A genuine manufacturer will send these to you within a day, while middlemen will keep stalling.

II. Certifications and Compliance
Musical fountains are electrically powered devices submerged in water, so compliance requirements are very high—especially if you plan to import into the EU or North American markets.

Check whether the manufacturer can provide:

CE certification (EMC) for the electrical components
IP68 waterproof rating covering submersible pumps and underwater lights
Any other regional certifications required by your target market
Certifications aren’t just for show. They provide you with legal protection in case of problems and serve as the fastest way to weed out “OEM middlemen”—those who merely slap logos on brochures and can be spotted at a glance.

III. Control System Technology
The control system is the fountain’s brain; it determines whether your fountain truly “dances to the music” or merely sprays water on a timer.

These are two fundamentally different technical approaches that cannot be used interchangeably:

Comparison Criteria DMX Control System Traditional PLC Control
Music Synchronization Accuracy Millisecond-level, frame-by-frame synchronization Second-level, threshold-triggered
Programming Method Timeline editing, WYSIWYG Ladder diagram programming, long debugging cycle
Scalability Modular, add or remove points at any time Limited by the number of physical I/O points
Maintenance Remote diagnostics, firmware updates Requires on-site technicians
Suitable Applications Musical fountains, integrated sound-light-and-water effects Simple循环 water features
For musical fountains, DMX is the industry standard. Manufacturers still heavily promoting PLCs are either selling you something that isn’t a musical fountain at all—just a water feature—or are still using technology from a decade ago. Neither of these is what you want.

IV. Modular Product Design
Traditional fountains are “one-time deals”: dig the pool, bury the pipes, install the equipment—and once it’s done, it can’t be changed. When you want to switch programs, you have to tear it all down and start over.

Modular fountains turn pumps, nozzles, lights, and control nodes into standardized, interchangeable building blocks. The benefits are immediate:

If something breaks, just replace the single module—no need to shut down the entire system
To change a show, you only need to modify the program—no hardware changes required
The entire system can be relocated and reused during site renovations
Ask this directly: “Are all your modules pre-assembled and pre-tested at the factory before shipment?” A reputable manufacturer will answer with a straightforward “Yes”—without hesitation.

V. Verifiable Case Studies
Anyone can post numbers like “1,000+ projects” on their website. If it can’t be verified, it’s zero.

Ask them to provide evidence:

Photos and videos of completed projects—not 3D renderings
Client references you can contact directly
Case studies in your region, or at least in your specific climate conditions
Manufacturers who’ve installed hundreds of musical fountains have already encountered every pitfall you can’t even imagine. This experience is the difference between “smooth acceptance in two weeks” and “endless troubleshooting for half a year.”

VI. One Team Handles Everything from Design to Maintenance
This is the aspect most easily overlooked, yet it quietly determines the project’s success or failure. Some companies only handle design, some only construction, and some only installation—very few can handle all three in-house.

Once design, construction, and commissioning are split among multiple companies, every handoff becomes a leak in the budget: responsibility gets passed back and forth, and the schedule gets delayed time and time again.

A full-chain team (design + construction + installation + maintenance—all handled by a single provider from start to finish) offers you a straightforward solution:

There is only one party to hold accountable for the entire project.
The design intent is carried through unchanged from the blueprints all the way to commissioning.
When problems arise, the response is swift because the same team of engineers is still on the job.

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.

II. Concept and Layout Design
1. Overall Layout: Employ symmetrical, matrix, and curved designs to complement the plaza’s style. When the system is shut down, the ground remains completely level, ensuring unobstructed pedestrian traffic and full site usability.
2. Water Feature Combinations: Select jumping fountains, rippling fountains, and steady-flow fountains; avoid large swinging features or extremely high water columns to effectively prevent water splashes from wetting pedestrians or causing disturbances to nearby residents.
3. Lighting Configuration: IP68-rated, pressure-resistant in-ground lights are installed to enable synchronized color changes between music, water patterns, and lighting, creating a rich nighttime visual experience.
4. Control System: Supports scheduled operation, music synchronization, and motion-sensor interaction, catering to diverse scenarios such as nighttime viewing and family-friendly activities.
5. Proposal Delivery: Provide floor plans, renderings, and performance proposals for client review and final approval.

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.
