| Project Name: | Polluted Runoff Control for Waialee Livestock Farm |
| ASO Log No.: | 04-199 |
| Start/End Date: | January 2004 to January 2006 |
| Federal Funds: | $200,000.00 |
| Matching Funds: | $202,795.00 |
| Contractor: | Dr. P.Y. Yang University of Hawaii College of Tropical Agriculture and Human Resources Department of Molecular Biosciences and Biosystems Engineering 1955 East-West Road, Ag Science Room 218 Honolulu, HI 96822 Phone: (808) 956-8384 |
| Background/ Overview: |
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 |
