Waialee Livestock Farm located in Waialee, Oahu, is close to Sunset Beach and Waialee Beach Park. It is a 135 acre farm operating as a dairy cow and sheep facility. The polluted runoff from the operation is affecting the coastal water via leaching from a small wetland and overflow from storm water. Polluted runoff includes dairy cow manure, fertilizer, soil erosion, sheep feed, and wastewater effluent from oxidation pond.
Objectives/Goals: To prevent and reduce NPS pollution by implementing a best management practice at the Waialee Livestock Farm to properly control manure and wastewater contaminants from entering into the surface and ground water resources in the Waialee Coastal waters.
Methods Employed: • A two stage anaerobic bioreactor with an aerobic Entrapped Mixed Microbial Cell bioreactor will be installed
• A new drainage system and fencing will be installed
• An aeration device with biological treatment support will be installed in the existing oxidation pond
Pollutants of Concern: Organic loading and nitrogen loading
Watershed: Paumalu, island of Oahu
Size of Project: 135 acres
Affected Water Bodies: Waialee Beach
Deliverables: • A demonstration wastewater treatment and runoff control system for farmers, students, researchers
• An illustration board for display of the system
• Video tape with instruction
• Web site to illustrate efforts
