Manure Pits
NRCS Concrete-Lined Manure Pit Description
A concrete-lined manure pit, designed in accordance with USDA NRCS Conservation Practice Standard 313 (Waste Storage Facility), is a reinforced concrete structure constructed to safely store liquid and semi-solid livestock manure. The concrete liner provides structural integrity and prevents seepage to groundwater, ensuring compliance with environmental protection requirements.
These pits are typically rectangular or circular in shape and can be below-grade, partially in-ground, or fully above-grade, depending on site conditions. The liner thickness, reinforcement, and joint design are engineered based on soil bearing capacity, hydrostatic pressure, and waste load.
Key Features:
Impermeable Concrete Liner: Prevents leakage and protects groundwater.
Reinforced Walls and Floor: Designed to resist lateral earth and fluid pressures.
Integrated Drainage and Pump-Out Systems: Allow controlled removal and transfer of manure for field application.
Slope Design: Floors are often sloped toward a sump or pump-out area for complete cleanout.
Compliance: Built under NRCS Standard 313 and local environmental regulations.
Concrete-lined manure pits are essential components of modern dairy and livestock operations, providing a durable, low-maintenance storage solution that supports nutrient management plans and environmental stewardship.
