Water suppply coming from spring sources and groundwater sources is treated with chlorine solution either by dript-type method or a hypochlorinator to ensure the the water supply is sufficiently disinfected before it is pumped into a reservoir or is pumped directly into the distribution lines for the consuming public in 35 out of 64 barangays of the City of Sorsogon.

SCWD's system of transmission and distribution lines as of December 31, 2022 is composed of approximately 300 kilometers of pipelines, ranging in diameter from 32mm (1-1/2") tp 300mm (12") and strategically placed gate valves/isolation valves numbering approximately 200 for proper water supply management. Pipe materials are primarily polyvinyl chloride and high density polyethylene, with older portions consisting of galvanized iron, cast iron and steel pipes.

Air release valves are installed along transmission and distributions line to expel air and facilitate water flow while blow-off points and fire hydrants are installed in strategic locations for flushing works and fire suppresion activities, respectively.

SCWD has 113 pressure monitoring points in the 34 barangays where regular pressure monitoring is performed. As of December 31, 2022, the SCWD service area has water supply at an average of 17 hours per day at an average preassure of 13.03 PSI.

Monthly average pressure monitored by SCWD at these points are as shown at the table below.

Service connections are either individually tapped or grouped into water meter clusters for meter reading and maintenance works.

It is not enough that potable water is available for distribution. The water distribution system must also be in tiptop condition to ensure efficient water service delivery to our beloved water consumers.
