Sensor Monitors Level
The float sensor sits inside the reservoir and continuously tracks the water level. No manual checking required.
Product Specifications
Irrigation Automation
The WaterUps Solenoid Reservoir Controller automatically monitors the water level in your wicking reservoir and fills it when it gets too low — stopping before overflow. Fully automated, zero-waste irrigation for commercial landscape installations.
System Operation
How the Controller Works
A simple, reliable four-step cycle that keeps your wicking reservoir at the optimal level — automatically, around the clock.
Low Level Detected
When the water level drops below the configured threshold (20% of reservoir capacity), the controller triggers the solenoid valve to open.
Reservoir Fills
Water flows through the solenoid valve from the connected supply (mains, tank, or recycled water) and fills the reservoir from below.
Full Level Reached — Valve Closes
When the reservoir reaches the configured full level (below the overflow pipe), the controller closes the solenoid valve. The system returns to monitoring mode.

Features
What Makes It Different
Automatic Reservoir Monitoring
The float sensor continuously monitors the water level in the reservoir. When the level drops below the configured threshold, the solenoid valve opens and begins filling.
Overflow Prevention
The controller automatically shuts off the solenoid valve before the reservoir reaches overflow level — protecting the planting medium from waterlogging and preventing water waste.
Low-Power Operation
Designed for low-power operation, the controller can be adjusted for battery or solar-powered installations — ideal for remote streetscape and park installations without mains power access.
Optimal Thresholds
Fill trigger and shutoff levels are designed to balance consistent soil moisture, power loss protection and rain water collection.
Compatible with BMS & SCADA
The controller can be integrated with building management systems (BMS) and SCADA platforms for centralised monitoring of large commercial and civic installations.
Future Remote Monitoring
An IoT connected module is currently in development — providing real-time reservoir level data.

Applications
Where Automation Makes the Difference
Indoor Installations
Automate filling and eliminate risk of overflow events — no seepage, staining or slip risk.
Rooftop & Podium Gardens
Remote-access rooftop gardens benefit most from automation — no staff required to monitor or fill reservoirs.
Public Parks & Civic Spaces
Reduce maintenance crew visits and ensure consistent plant health in high-visibility public spaces.
Stormwater Reuse Systems
Connect the controller to a stormwater tank — design your system to automatically draw from captured rainwater instead of mains supply.
Community & School Gardens
Ideal for installations where regular maintenance is not guaranteed — the system keeps plants healthy during school holidays and weekends.
Hotel & Hospitality
Maintain lush, healthy planting in high-profile hospitality settings without relying on maintenance staff to monitor water levels.
