ABSTRACT

The Municipality of Dr. Jose P. Rizal is located in the southwestern shores of the
province of Palawan characterized by topography of hilly to mountainous terrain. It is
approximately 207 kilometers away from the City of Puerto Princesa, the capital city of
Palawan. It is a first-class municipality composed of 11 barangays. The economy is
predominantly agriculture where the predominant sources of livelihood is farming and
fishing. Barangay Punta-baja is the center where the seat of government is located.

Rizal Waterworks was conceptualized and implemented through the

collaborative effort of the Provincial Government of Palawan (PGP) and the Local
Government Unit of Rizal (LGU-Rizal) to provide clean and potable water supply to its
constituents. PGP spearheaded the project by conducting the feasibility study and
providing the detailed engineering design. The LGU-Rizal, as the main proponent of the
project, financed the required funding through a 20-year loan grant from a government
financing institution.

Around Sixty Percent (60%) of the Municipality’s domestic water comes from Rizal
Waterworks, an LGU-run water utility, which started its operation in February 2016, by virtue
of Municipal Ordinance 2017-015. At the onset, it covers only 1 barangay, the Barangay
Punta-Baja, but eventually expanded its operations to cover the whole barangays of the
Municipality. It provides a level III water service.

Rizal Waterworks gets its source from surface water and ground water. It has a total
length of pipeline laid of 123,567 linear meters, covering 11 barangays of the Municipality. It
is mandated to provide safe, potable, affordable and dependable water to its service areas.
Currently, it has 3,089 household connections translating to approximately a population of
12,356. It is the only water service provider in the Municipality.

Rizal Waterworks draws its raw water from three (3) major river systems and five (5)
deepwells located in various locations within the municipality. It consist of three (3) river-fed
water treatment systems and five (5) solar powered deepwell water systems with a total
combined production capacity of 6,300 m3/day (CMD). Production of water strictly follows
the Philippine National Standards for Drinking Water (PNSWD).
 The Water Safety Plan (WSP) focuses on monitoring the safety of drinking water
supply from its catchment to Rizal waterworks concesssionaires. This WSP comprises the
protection of the water sources, water treatment plants, pumps and reservoirs from risks
that will endanger the quality of water being delivered.

The plan covers the Rizal Waterworks’ water supply and distribution systems in all
Water Treatment Plants and the 5 solar-powered deepwell stations.

INTRODUCTION

The Municipality of Dr. Jose P. Rizal was formerly a part and under the administrative
jurisdiction of the Municipality of Quezon. The municipality was created as Marcos town on
April 14, 1983 by virtue of Batas Pambansa No. 386 and was renamed Dr. Jose P. Rizal by
virtue of Republic Act No.6652 dated July 27, 1987 which lapsed into law and become
effective on April 17, 1988, to give tribute to our national hero. Rizal is noted for its rich and
abundant natural resources. It is bounded by the Municipality of Bataraza in the south, by
the Municipality of Quezon in the north, by the Municipality of Brooke’s Point in the east
and on the west by the West Philippine Sea. The Municipality has a total land area of
125,915.46 hectares, and is composed of eleven (11) barangays. According to the 2022
census, the town had a population of 58,936 people in 14,734 households, and a growth
rate of 2.44%.

The Rizal Waterworks is an LGU-owned and run water utility, established by

virtue of Municipal Ordinance 2017-015, an ordinance establishing the Rizal
Waterworks Office (RWO), which started its operation in February 2016. At the onset, it
covers only 1 barangay, the Barangay Punta-baja, with only 100 Hh connections but
eventually expanded its operations to cover the 11 barangays of the Municipality. It
provides a level III water service to all its concessionaires.

The Rizal Waterworks was established as an economic enterprise under the

umbrella of the Municipal Economic Enterprise Development Office (MEEDO), a line-
department of the LGU-Rizal, which is mandated to operate and manage all
established economic enterprises.

At present, the Rizal Waterworks is the only water service provider within the
jurisdiction of the municipality of Rizal. It provides a level III water service and
currently has 58 personnel or a ratio of 1:53 per service connection.
OUR VISSION

A premier financially self-sustaining LGU-run water utility, having adequate ang

highly competent personnel, with sufficient and innovative equipment and facilities,
providing potable, adequate, reliable and affordable water supply to its
concessionaires.

OUR MISSION
To equitably provide potable, adequate and reliable water supply, accessible to all
waterless households in the target service areas at affordable and reasonable cost.

LEGAL BASIS

Department of Health (DOH) Administrative Order No. 2014-027 mandates all

drinking-water service providers to develop and implement a Water Safety Plan (WSP).

In compliance to this, the Rizal Waterworks organized and commissioned a

team of experts to formulate and develop a Water Safety Plan. The newly assembled
team underwent a rigorous training, workshops and walk-throughs to identify and
assess the hazards and risks that may jeopardize the water quality being supplied to
water consumers. The team conducted periodic meetings and consultations to
ensure that the WSP addresses the identified hazards. Moreover, control measures
were considered for each identified hazard.

The WSP focuses on monitoring the water safety from its source to the
concessionaires. It involves the protection of the water sources, the transmission
lines, water treatment plants, pumps, reservoirs and distribution lines from all risks
that will endager the water quality being supplied to concessionaires.

Specifically, this plan aims to:

1. Ensure safety and potability of supplied water from its source to the tap of
every home of all concessionaires;
2. Prevent contamination of water by identifying potential risks and
addressing these risks quickly and effectively with appropriate control
measures;
3. Provide policies and procedures to maintain quantity and quality of service
even during adverse conditions;
4. Facilitates decision-making on critical issues in a potentially stressful
environment and define responsibilities and roles during emergency
situation;
5. Provide procedures for lessons learned following every emergency or
unforeseen events to guarantee that every hazard and issues are covered
and prevent re-occurrence in the future.
