It’s Raining. Really!

Patrick Gourley from Christ’s Church of the Valley in San Dimas, California made in rain during their worship services. Really. Rain.

For their Good Friday services they wanted to juxtapose the idea of desert and dryness with water and life. So they first made a background out of crushed aluminum screening stretched onto frames. The upper center panels were on a counterweight system and raised to reveal a cross during the climax of the service.

Then they installed two rain pipes – one upstage and one downstage of the band. That left the band in the middle of the rain nice and dry. The pipes were made out of ABS with holes drilled every few inches. They hung them with turn buckles to make sure the pipe was level the entire length for consistent flow. Regulators were installed to control intensity of the rain throughout the service. The rain fell into troughs on the floor that were lined with black plastic sheeting. The troughs were built on a slope so water would pool at one end were pumps were located to pump the water outside to a drain. They also filled the troughs with left over screen material which cut down the noise and limited water from splashing out.

They were not able to make it a closed system where the pump would circulate the water due to the height and the pressure that was required to get it to the pipes in the ceiling.

They also took great care and caution with all of the power that was required for band and lighting.

Creating Atmospheric Rain Effects for Worship Services

Incorporating actual water effects into a worship environment represents one of the most ambitious undertakings in church stage design. The technical challenges of creating convincing rain while maintaining safety, protecting equipment, and ensuring reliable operation require careful planning and engineering. This installation from Christ’s Church of the Valley demonstrates how thoughtful design can transform a conceptual vision into a powerful experiential element that reinforces the message being communicated.

The theological symbolism of water runs deep throughout Christian tradition, making rain a particularly meaningful visual metaphor for services focused on themes of renewal, cleansing, and life. By juxtaposing the arid desert imagery with falling water, the design team created a visual narrative arc that paralleled the spiritual journey from dryness to abundance. The crushed aluminum screening backdrop provided an appropriately stark, desert-like texture that contrasted dramatically with the shimmering water effects in front of it.

The mechanical engineering behind the rain system reveals sophisticated problem-solving that balanced aesthetic goals with practical constraints. ABS pipe was selected for its durability, light weight, and ease of modification. The decision to drill holes at regular intervals rather than using commercial rain nozzles allowed for custom control over droplet size and distribution. Turnbuckles provided the precise leveling necessary for consistent water flow across the entire length of the pipe, preventing the uneven dripping that would break the illusion of natural rainfall.

Water management proved to be one of the most complex aspects of the installation. The sloped trough design with submersible pumps at the collection point created an efficient removal system that prevented flooding while allowing the effect to run continuously throughout the service. The addition of leftover screen material in the troughs demonstrates resourceful thinking, serving the dual purpose of sound dampening and splash containment. This attention to detail ensured that the water effects enhanced rather than distracted from the worship experience.

Safety considerations were paramount given the combination of water and electrical systems in close proximity. The team’s careful planning around power distribution for band equipment and lighting prevented any dangerous interactions between water and electricity. Modern churches attempting similar effects should consult with licensed electricians and consider GFCI protection for all circuits in the vicinity of water effects, along with backup shutoff systems that can instantly stop water flow if needed.

Pro Tips for Water Effects in Church Stage Design

Plan Your Water Source and Drainage First: Before designing any water effect, confirm that your venue has adequate water supply and drainage capabilities. The Christ’s Church team had to pump water outside rather than recirculating it due to pressure limitations. Test your drainage capacity by running water at the intended flow rate for the expected duration of your service to ensure no flooding occurs.

Use GFCI Protection: Any electrical equipment near water must be connected to Ground Fault Circuit Interrupter (GFCI) protected circuits. This includes lighting, sound equipment, and band instruments. Have a licensed electrician review your setup before the first service with water effects to ensure compliance with local codes and insurance requirements.

Rehearse with Water: Water effects behave differently in practice than in theory. Schedule multiple rehearsals with the full water system running to identify issues like splashing, noise, or lighting reflections that might not be apparent during dry runs. The screen material in the troughs was a solution discovered during rehearsal that significantly improved the final effect.

Have Emergency Shutoffs: Install easily accessible shutoff valves that can stop water flow instantly if problems arise during a service. Train multiple team members on their location and operation. Consider installing floor sensors that can automatically shut off water if levels rise above safe thresholds.
