The study identified and evaluated the various options for the expansion and improvement of the waste water treatment lagoon for Clark Water Corporation (CWC).
The study conducted also addressed the following major concerns in the operation of the waste water treatment facility:
- Effluent quality does not meet DENR DAO 35 in color, COD, TSS, pH, oil and grease and coliform .
- The existing facility was designed to treat domestic wastewater, while the waste water generated from the Clark Export Processing Zone is a mixture of domestic and industrial zone wastewater.
- Sludge accumulated at the existing anaerobic ponds and the other ponds could not be evacuated because the lagoons have no sludge drying beds.
