A  FEASIBILITY STUDY REPORT

ON THE PROPOSED IMPLEMENTATION

OF THE SALUMAY POTABLE WATER

SYSTEM PROJECT

Located in Barangay Datu Salumay

Marilog District, Davao City

EXECUTIVE SUMMARY

The proposed SALUMAY POTABLE WATER SYSTEM PROJECT  is a gravity –type level-2 system which will be supported by a spring with a current yield of 1 liter per second. The system will be using 50% of the gauged yield. Below is a matrix showing a brief description of the project.

Based from the initial study made on the proposed project, the Salumay PWS can supply the water needs of the community even up to a span of 5 years using 90% of the current spring yield. The assumption made on this claim is for each of the beneficiary to make use of the ideal clean and potable water for cooking, drinking and other household use.

                                                                                                                   Recommendation  : Based from the result of the initial study made, the proposed project DATU SALUMAY POTABLE WATER SYSTEM                                                                                               recommended for project Implementation.

I. BRIEF DESCRIPTION OF THE CITY OF DAVAO

The CITY of DAVAO is located in the south-eastern part of the province of Davao del Sur  please see attached Map). It is bounded in the north by the city of Panabo and the municipality of Arakan in the west; and the municipality of Sta Cruz, Davao del Sur in the southerly portion of the City. The City of Davao could be reached by all types of land vehicles through a well-paved all-weather road.  Davao City has one hundred eighty six (186) barangays and has a total population of 1.2 million ( data gathered thru city planning and development office).

There are two main geographical districts of the city, namely: upland and low land districts. The lowland district is predominantly an agri- business area. Most of the production sites are linked to the market via a network of highly-distressed all-weather sand and gravel road. On the other hand, the upland district practices the slash and burn technology for agriculture. Corn and vegetables are the primary produce. The Davao River and Lasang River served as the source of irrigation water for the lowlands.

Based on the CY 2001 Data on Water Supply, the city of davao has a total of 334,000 households. Of this figure, only households or an approximate 57% ( of the total households) have direct access to both Levels 1, 2, and 3 Potable Water Sources.

II. BRIEF DESCRIPTION OF THE BARANGAY DATU SALUMAY

Barangay Salumay is one of the upland villages of Davao City. It is nestle at the upper section of the Mt. Talomo mountain range and is bordered by barangays Buda  in the north;  and Baganihan in the south.

Based from the CPDO records , the village has a total population of 2,897 individuals. Majority of the population is composed of Christians and Indigenous peoples, while the ata Manobos comprise the  major ethnic group of the area.

Corn and vegetables are the primary produce of the village. The residents practice Slash and burn technology for agricultural purposes ( please see attached picture ). Intermittent  springs and inland water support the irrigation requirement of the above-mentioned crops.

Datu Salumay could be reached from Barangay Ulas by upland vehicles through a well asphalted road – the Davao - Bukidnon Road National Highway. Aside from established Public Utility vehicles such as buses and jeepneys; “Habal Habal and Skylab” are the two popular mode of transportation among the residents going to other sitios of the barangay.

III. HEALTH AND SANITATION SITUATION OF BARANGAY DATU SALUMAY

Base from reports, 85% of the Household have sanitary facilities (water sealed toilets). The said scenario compliments the presence of adequate and effective health and sanitation program implemented in the Barangay. This is a result of the unrelentless cooperation given by the residents to the Barangay health program manage by brgy. Health workers. It was also noted that diarrheal diseases ranked sixth as a cause of mortality for children below 5 years old.

IV. EXISTING POTABLE WATER SOURCE

The household water needs of the village depend on rain water, surface water and intermittent springs flowing out of the mountain sides. Water from these sources are piped-in through PE pipes (see picture attached) to communal stands where households could fetch their water requirements.

Based on the 5 years Barangay Development Plan report, three (3) existing potable water system in the village. However, only 28% of the households are effectively served by the water system it is so because of the absence of a comprehensive project feasibility study (technology development and social adaptability).

The village has sources of potable water as observed during the conduct of the Ocular survey. However, water not reaching the center of the village  is a threat due to the absence of an effective technical design resulting to waste of funds as seen in the 3 existing water system.

V. THE PROPOSED DATU SALUMAY POTABLE WATER SYSTEM

There are two (2) sitios to be covered by the proposed Potable Water System. Presented in Table 1 are the sitios covered including the of households to be benefited.

Table 1: Sitios covered including the number of HH beneficiaries.

The proposed system is categorized as gavity type. It will be supplied by a spring located at an altitude of 1240 meters above sea level ( masl ) at a latitude of North 6 degrees 33 minutes and 42.2 seconds ; and a longitude of East 124 degrees 28 minutes and 34.3 seconds. The spring has a yield of approximate 2 liters per second and was gauged November 21,2005 about 90% of the yield will be used for the systems.

The center of the barangay is approximately 1225 meters above sea level ( masl ) at a latitude of North 6 degrees 33 minutes and 21.1 seconds, and a longitude of East 124 degrees 28 minutes and 34.5 seconds.

Below is a matrix showing the proposed structures for inclusion in the design of the system:

Table 2: Structural considerations for the system.

VI. DEMAND

VI. 1. WITHOUT THE PROJECT

Considering the distance and the nature of the current sources of potable water needs in the community, it is estimated that the water requirement of the residents without the project range from 20 liters per capita per day 25 liters per capita per day or an average of 25 liters per capita per day. The proposed project will benefit a total of 200 households from the identified2 puroks. Average household membership is five (5) with an average annual population growth rate 3%. Below is a table showing the project water demand of the identified beneficiary sites without the project.

Table 3: Project Water Demand without the project.

V1.2. WITH THE PROJECT

When the project will be in full operation, the average water consumption of the identified beneficiary sites will be increased to 60 liters per capita per day. This will result to change in lifestyle of the people by improving their health and sanitation as result as well as having time saved ( from water fetching ) for productive activities ( e.g. backyard livestock production, backyard gardening, etc.. ) as well as quality time for the family. The children on the other will be able to attend regular classes in the school. Below is a table showing the projected water demand of the identified beneficiary sites with the project.

Table 4: Project Water Demand with the project.

VI.3. DEMAND AND SUPPLY GAP

The 200 household beneficiaries identified from the two puroks of Barangay Datu Salumay will sufficiently enjoy potable water requirement of 60 liters per capita per day. Based from a projected population with an annual population growth rate of 3%, it could be gleaned from table 5 that the system could still efficiently and effectively deliver the water needs of the beneficiaries even at the end of the fifth year.

Table 6 : A comparison of the demand and supply without and with the project.

The table shows that with the development of the spring, the water will be more than enough to support the household needs of the identified beneficiaries. At the end of the 5^th year, an excess of 8,520 liters per day could still be recorded from the system using 50% of the recorded spring yield.

VI.4. DEMAND AND SUPPLY ANALYSIS

Below is a table showing an analysis of the demand versus supply with the project and without the project.

Table 7:Demand and Supply Analysis Table.

Noted : the Php 30.00 water fee per month was gathered from the result of an initial interview with some of the identified beneficiaries.

VVI. IMPACT TO WOMEN

During the conduct of Ocular Survey, it was found out that women and children do the regular fetching of water at makeshift taps. It was also known that an average of 40 minutes is spent for fetching water per session. There are three (3) fetching sessions per day namely: morning, noon and dusk/evening.

If the system be pursued, fetching time will be shortened by an average of 25 minutes. Presented below is table 3 showing quarterly and annual losses incurred in terms of time and monetary values.

Given :

          Local Wage Rate   : Php 150.00

          Number of Working Hours    : 25 minutes

Table 8 : Losses incurred in fetching water in terms of time and monetary values per Household.

Analysis: Should the system be pursued, the following will be the benefits derived By women in terms of system use.

·        Women and children will be able to save a total of 456.25 annually ( per household) fetching water.

·        Women will be able generate a total additional income of Php. 8,555.00 annually ( per household ) from productive time use ( both in cash and in kind ).

·        Children will now be able to attend regular class sessions in school.
