The Ritchie Omni 1 Green Automatic Waterer (Part #18516) delivers dependable, energy-efficient hydration for horses and cattle in a compact, insulated design. Finished in durable green, this model offers the same trusted performance and specifications as the yellow Omni 1 — the only difference between the two units is the exterior color.
Combining the durability of a stainless steel trough with the efficiency of a fully insulated poly housing, the Omni 1 is engineered for both performance and animal safety. Smooth, rounded edges help protect livestock while the insulated construction improves energy efficiency and helps maintain water temperature year-round.
Designed for cold climates and winter reliability, the Omni 1 features thermostatically controlled heating elements mounted beneath the stainless steel trough to help prevent freezing. A fast-refill valve ensures consistent water availability, making this heated automatic waterer ideal for stalls, smaller pens, or paddocks serving up to 20 head of cattle or horses.

Additional Accessories and Considerations:
- Anchor Bolts: Use 5" x 3/8" anchor bolts to secure the unit.
- Sealant: Apply an all-weather sealant around the base to prevent air gaps and cold from penetrating underneath.
- Electric Requirements: The Omni Series requires electricity for its heating system but remains energy efficient throughout winter.
- Water Pressure Regulation: High water pressure exceeding 60 PSI may cause valve leaks. Install a pressure regulator to maintain optimal performance.
- Stop and Waste Valve: Consider adding one to drain the line back to the source when not in use. This is a long-term solution to protect your waterline.
- Level Installation: Ensure the waterer is installed on a level surface for proper operation.
To install a Ritchie automatic waterer, you’ll need a buried waterline and a concrete pad.
