Brief Description of the Division’s Function

All raw water and treated water distribution lines are monitored and managed by the Engineering Division. Improvements, expansions, extensions and maintenance falls under their function. The Engineering Division is responsible in the planning, design and construction of the District’s facilities and preparation of as-built plans of completed works and projects. It is also responsible in the operation, maintenance and improvements of all transmission and distribution mains including all its installed appurtenances and accessories in order to ensure delivery of sufficient potable water 24/7 to the customers through the highest level of professionalism and efficiency. It is likewise responsible in the proper identification, selection and utilization of materials and equipment in accordance to technical standards set by competent authorities in terms of quality and proper size.



Management Procedures are compilations of actions to be taken in every step of the Water Supply System. It defines the actions to be taken during normal and emergency operational conditions and details the steps or procedures to follow in specific incidents and situations (corrective actions) when critical limits are exceeded. Management Procedures or commonly referred to as “Standard Operating Procedures” (SOPs), are documented and updated from time to time to comply with the changing trends in the water supply system of SANWAD.

The Management Procedures are prepared by experienced personnel on the different steps and critical points of the system. Such procedures are based on historical records of the Treatment and Distribution section. Developments pertaining to corrective actions were undertaken to comply with the present set-up of the water supply system. Such updates, developments or adjustments are consistently documented to form part of the SANWAD Standard Operational Procedures for Water Safety Actions.

At present, the Engineering Division has a Rapid Action Team that responds to emergencies like leak repairs or no-water complaints beyond office hours. The Production Division likewise has formulated its own crisis control scheme. Each section hastily applies its operational procedures which were all crafted from experience and historical events from years of Plant operation.

SANWAD Management Procedures require the formulation of a Crisis Management Plan (CMP). Its sole purpose is to standardize all procedural matters pertaining to emergency situations in the water supply system during disasters, whether natural or man-made. Subsequently, a CRISIS MANAGEMENT TEAM (CMT) and a CRISIS RESPONSE TEAM (CRT) is to be activated to effectively and promptly respond to emergencies and counteract possible impacts on the health targets and water supply.

As part of SANWAD’s non-stop quest for excellence, the effectiveness and efficiency to accomplish its mission and vision is at the heart of this Water Safety Plan. As such, it is extremely necessary to conduct regular monitoring of each process step and apply corresponding corrective actions for every deviation in the water supply system. Moreover, incident reports are to be constantly chronicled for future reference.


The Operation and Maintenance Section of the Engineering Division shall be in charge of implementing Standard Operating Procedure when hazardous events occur at any point of the SANWAD distribution system. The Property Supply Office of the Admin/Finance Division shall provide the needed materials or equipment to address hazardous event.

For the case indicated above, the Customer Services Section of the Commercial Division is tasked with the Information Dissemination program of the Santiago Water District. Advisories for low water or no water occurrences as well as quality of water shall be circulated via broadcast media.
