Short answerEQIP funds a solar stock-water system as a set of NRCS conservation practices, chiefly Pumping Plant (533) with Watering Facility (614) and Livestock Pipeline (516), often alongside Water Well (642), Spring Development (574), Fence (382) and Grazing Management (528). Apply through your local NRCS office and sign the contract before buying anything.
Key takeaways
- Solar stock water is funded as practices: 533, 614, 516, plus 642, 574, 382, 528 as needed.
- The 2026 Pumping Plant standard sets PV sizing criteria, including 10 years of degradation.
- Sign the EQIP contract before buying anything.
The practices
| Code | Practice | Covers |
|---|---|---|
| 533 | Pumping Plant | The pump and its power unit, including photovoltaic panels |
| 614 | Watering Facility | Troughs and tanks |
| 516 | Livestock Pipeline | Pipe from source to troughs |
| 642 | Water Well | A new well where one is needed |
| 574 | Spring Development | Collecting and protecting a spring |
| 382 | Fence | Excluding stock from streams, protecting the installation |
| 528 | Grazing Management | The grazing plan the water supports |
What the 533 standard asks of a solar array
The national Pumping Plant standard, updated in 2026, names photovoltaic panels as an accepted power unit and sets design criteria for them. In summary:
- Size the array from average solar data for the location and the time of year pumping happens, following the pump maker's recommendations.
- Make sure the array runs the pump at the design flow rate, with an allowance for at least 10 years of panel degradation at no more than 1% a year.
- Orient fixed arrays for maximum efficiency and base tilt on latitude and season; mount them to resist wind and movement.
- Install electrical work to the National Electrical Code.
- Consider mobile panels for rotational grazing, and tracking or seasonally tilted panels.
How payment works
Each state publishes a payment schedule with a rate for each practice scenario, re-evaluated every year from local material and labour costs. Historically underserved producers (beginning, limited resource, socially disadvantaged and veteran farmers and ranchers) can receive higher rates. Payment comes after the practice is installed and certified against the standard.
- Contact the NRCS office at your USDA Service Center.
- Work out a conservation plan that includes the water system.
- Apply before your state's ranking date.
- Do not buy or install anything until the contract is signed.
EQIP vs REAP
For a stock-water system, EQIP is usually the better fit. USDA Rural Development's REAP page said in October 2026 that it was not accepting REAP grant applications, and under the rule effective 16 October 2026 a REAP grant covers at most 25% and only after the system is built and running. See USDA REAP and EQIP.
Questions
- What NRCS practice code covers a solar water pump?
- Pumping Plant, Conservation Practice Standard 533. Its 2026 national standard lists photovoltaic panels as an accepted power unit. A stock-water system usually also includes Watering Facility (614) and Livestock Pipeline (516).
- Will EQIP pay for a solar pump I already installed?
- Generally no. EQIP contracts must be in place before the practice is installed. Contact your NRCS office before buying anything.
Size the system before you meet NRCS: daily water, lift, panels and tank.
