Choosing a Sprinkler Pump for Grey Water Recycling in the Caribbean

Designing an irrigation system for a school in Antigua presents unique challenges: no fresh water supply, reliance on grey water stored in two inground tanks, and a soccer field 200–400 feet away. The system must run on 110V/60Hz power and connect to standard ¾-inch garden hoses with Y-splitters for sprinklers. A previous attempt with a rental submersible pump failed—poor pressure with one sprinkler, none with two, and the pump burned out.

Key Considerations

• Water Source: Two grey water tanks, 200 feet apart, each roughly equidistant from the field.
• Power: 110V/60Hz (US standard).
• Delivery: Equipment can be shipped to Miami and forwarded to Antigua.
• Durability: Warranty support is impractical; the pump must be robust.
• Configuration: Portable or fixed, submersible or surface—flexibility is welcome.

Recommended Approach

This scenario requires professional irrigation design, not just pump selection. Factors like total dynamic head, flow requirements for multiple sprinklers, pipe sizing, and pump curve matching are critical. A centrifugal surface pump with a suction lift capacity (if tanks are below grade) or a submersible pump rated for dirty water (grey water) would be appropriate. The pump must deliver enough pressure (typically 40–60 psi) and flow (10–20 GPM) to run multiple sprinklers simultaneously through 200–400 feet of hose.

Because the design involves hydraulic calculations, pipe friction losses, and pump sizing, it's best handled via direct consultation. I've worked in Antigua and understand the local conditions. Please contact me at my work email to discuss specifications, pump models, and system layout in detail.
