Infrastructure and Utilities Sector: Water Supply

The information contained in this article were based on the Comprehensive Land Use Plan (CLUP) of Rosario, Batangas for the planning period 2000-2010 and were current in 1999 except in places where updates were duly noted.

THIS SOCIO-ECONOMIC PROFILE reports about three major sectors including the Social Sector, the Economic Sector and Infrastructure and Utilities Sector. The Infrastructure and Utilities Sector consists of the following sub-sectors: transportation, water supply, power services, and communication. This article covers the Water Supply Sub-Sector.

EXISTING SITUATION
Waterworks System
The waterworks system of Rosario, considered as a level III water supply service is being operated and managed by the Rosario Water District. The system source its water from barangays San Roque , Quilib, Bagong Pook, Namunga and Tombol Hill in Poblacion B.

There are 6 interconnected pumps, with each source having one pump each, except with Tombol Hill with 2 pumps. The total capacity of these source and pumps is about 49 liters per second or 4,233,600 liters per day. There are total of ten (10) barangays covered with 60 percent of the total households in those barangays served by the system and 40 percent unserved.

Location of Water Sources, Capacity and Service Coverage of Waterworks System Municipality of Rosario, Batangas: 1999
  • Poblacion B (2 pumps) in Tombol Hill - 1,036,800 liters/day covering Poblacion A, B, C, D & E serving 1,207 households

The standard water demand requirement for residential consumer of level III water supply system as developed by the Local Water Utilities Administration (LWUA) is 100-110 liters per capita per day (lcpd) per individual connection. With the current domestic or residential connections of 2,155 households with an average household member of 5 persons, the required volume of water for residential consumption is 1,185,250 liters per day.

For commercial/industrial connections the standard is 1.0-2.0 m3/day/connection. With the present number of commercial and semi-commercial connection, the requirements are 624 m3/day.

With present total type of consumers/connection of existing waterworks system, the requirements is 1,809,250 liters per capita per day. Considering the present capacity, which is 4,233,600 Lcpd, the present system is adequate. There is still an excess of 2,424,350 liters. The system had just been expanded and is still in the process of registering new subscribers and customers for wider coverage.

Level I System
The majority of the population about 86% get water from level I sources such as individual water system with generated and tank tubed/piped deep wells, shallow wells, dug wells, spring, lake, river and rain water. There are also water peddlers that delivers water to households. Household survey shows that there are about 4,602 households that get water from faucets of individual water system put by each household with own generating unit and water tank. Dug wells are the least source of water supply with 252 households during water from said sources of water supply.

Sources of Level I Water Supply Services Municipality of Rosario, Batangas: 1999
Type of Water Source, Number of Households and Percent to Total
  • Faucets (Industrial Water System) - 4,602 households - 34%
  • Deep wells/Shallow wells - 4,206 households - 31%
  • Dug wells - 252 households - 2%
  • Rainwater and Springs - 1,450 households - 11%
  • Peddlers - 2,971 households - 22%
  • Total 13,481 households - 100%

DEVELOPMENT NEEDS
The current situation in water supply service can be said to be adequate in some aspects but is generally inadequate. The present waterworks system has a capacity of 4,233,600 liters per day, while based on listed consumers, the total consumption is only 1,809,250 liters per day, thus an excess of 2,424,250 liters per day. The system can still accommodate about 4,408 households.

Considering the present residential connection as households and the additional 4,408 households that can still be accommodated in the system, the total households to be served by the system will be 6,523 or 41% only of the total . The remainder has to source water from other water supply service sources.

This is based on water demand standard requirement developed by the Local Water Utilities Administration (LWUA) of 100-110 liters per capita per day per residential individual household connection and 1–2 cubic meters per day for commercial and industrial connections. These standards are for level III water supply services.

For purposes of future requirements, there is a need to plan and program an overall water supply service system that will provide adequate and accessible water supply service to the population.

Expansion of present capacity of waterworks system, establishment of Level III water supply service and provision of equipment and facilities for level I point and distribution.

Studies and research on other sources of water is also necessary to augment present facility. Tapping of potential water sources is also recommended.

Developing of new watershed areas and preservation of existing ones are ecological measures that can be done to maintain water resources in the areas. These can be done through tree planting, reforestation and forestation of elevated areas.

In areas with slopes 18% and above, forest plantations can be established. In watershed areas, vegetative measures and structural measures should be constructed to ensure abundant supply of water even during dry season especially around Tombol Hill at Barangay Poblacion B and San Roque.

Environmental Sanitation must be maintained to sustain potability and water quality of water resources both ground and surface water.
