9. Design and construction of the ponggol pigwaste plant

The Ponggol Pigwaste Plant was designed to treat the wastes from a farm with a standing pig population of 35 000. It included eight unit operations that could be combined to provide different levels of treatment. The cost of construction in 1985 was 2 million USD or 61 USD/SPP. The plant was operated for several years. During the first year of operation, the annual operating cost (AOC) was 2.75-5.83 USD per pig marketed per year. This chapter highlights the steps taken in construction, the design parameters and considerations, the cost of construction, and the cost of operation.
