For many small and medium enterprises and housing estates, conventional wastewater treatment system are technically sophisticated and costly, and it often requires high energy inputs for operation and rely on sophisticated maintenance services to ensure continuous operation of the project. In most cases, this requirement is highly unsuitable to SMEs. Many governments passed new environmental regulations to meet the standard for wastewater discharge for such small and medium enterprises and housing estates. They are responsible for the wastewater pollution which should be treated on-site, before discharging it to the bodies of water.

                                                        

Public Institutions like Iloilo Mission Hospital (IMH) highly needed a Wastewater Treatment Plant, this hospital was considered as one of the major sources of domestic wastewater in the area. This domestic wastewater generally includes materials disposed through toilets, sinks, tubs, showers, floor drains, washing dishes and laundry washing machines. Like other hospital or a health care industry, this wastewater must be treated and disposed of, in a manner that minimizes potential harm to public health and bad impacts to the environment. When untreated, wastewater is discharged to water bodies such as creeks, river and streams and sea which contaminate water with harmful bacteria and nutrients, and it causes a foul odor which can affect the community and patients. Without the treatment plant, it is obvious that the discharged wastewater quality does not meet the Philippines effluent standard.
 

                         

Iloilo Mission Hospital wastewater effluent generated from different sources shall be treated by a combination of Anaerobic and Aerobic processes to significantly reduce the pollution level before discharge.
