Last Dec. 15, 2008, the Contractor for the Davao City Pilot Project, All Trade Resourc es, mobilized their workforce in Barangay Waan in accordance with their revised work schedule. Durin g the first day, the bunkhouse was built close to the tank site and a preliminary staking of the pipeline was conducte d simultaneous with the site clearing of some WS facilities. On the next day, backhoe equipment was mobilized to start the excavation work for the foundation of the tank. Afterwards, the equipment was transferr ed to continue excavation work for the transmission line from the Tank site up to the Well No. 2. Some local residents were employed by the Contractor to undertake excavation equipme nt job; the work is easily delivered as they have not encountered some problems on site while doing the activities. Despite the long holiday season, the Contractor took only one day off (Dec 25) and kept on working at site to keep up with A backhoe excavates for pipeline nearby a post in Purok 12. the work schedule; the Project Engineer is always there to closely supervise the activities . At the same time, JICA WS Supervisor conducted regular inspection of the Contractor activities to ensure that the work is in accordance with the plans, specifications and work schedule. At the end of December 2008, the Contract or work accomplishment was evaluated at 8.57%.

No. 17 (December 2008) Groundwater activity updates… BY MICHAEL C. NACPIL The next phase in the program for Groundwa ter Development is the well drillings in the pilot sites. These included Electric L ogging and series of Pumping Tests. For Davao del Norte, the cutting samples c ollected from the drilled wells in Brgy. Alejal, Carmen confirmed the result of the geo-resistivity test that we conducted in the previous months. For Well#02, we found a potential aquifer below 40 m depth but its properties included high salinity with dissolved gasses making it potentially flammable so we decide d to seal the borehole to avoid possible mishaps. For Well#03 which had a 65m depth, the borehole electric log test showed th at we can use an aquifer from a depth of 10m to 21m, and the pumping test showed that it will yield not less than 4.0 liters per second of water. On the other hand, the drilling in Well#01 is cancelled since it is very near to Well#02 Groundwater workshop on modeling and database held last December 9-10 at Amigoas Cafe so it's highly probable that it also has dissolved gasses. A geo-resistivity survey On the other hand, the yield of Well#03 is The mobilization in Davao Oriental will be c onducted in January 2009 to 4.1 l/s while Well#01 has at least 5.0 l/s will be on January 2009. Completion of determine the location of the replacement and a 0.5 l/s free-flowing discharge as other groundwater activities for the pilot measured using the 60° triangular weir. sites is scheduled on February 2009. The pil ot site of Compostela Valley in For Davao del Sur, Well#01 and Brgy. Cabidianan, Nabunturan was the Well#02 in Brgy. Bangkal, Matanao were workshop on "Groundwater Vistas" was first to be completed in the drilling of its already completed. Well#01 has an held. This software can be used in proposed wells with the lithology of the aquifer between the depth of 18m and predicting aquifer flow including the boreholes approximating the results of 38m and Well#02 between the 31m and effects of contaminants or any recharge vity tests that were conducted. 61m depths. Pumping tests for these from other locations. This is very helpful Pumping tests indicate that Well#02 have wells would be completed in January to in observing the properties of our well the least yield with approximately 0.6 l/s. determine their well yields. Construction in Barangay Waan from page 1… No. 17 (December 2008) BAWWASA Election of Officers: A Milestone in the Community BY KEVIN R. FERNAN The participation of community Barangay Waan Water and Sanitation d by its participation in the Association Officers : Mr. Warren Kunat December 19, 2008, a great leap was taken in Brgy.

It is a well participated electoral event and Board of Directors can be compared to political exercises 6. Saidor Sanggila of its loc al government. According to Barangay officials, only three (3) 2. Dondie Labawan 7. Saleh Labawan puroks in the whole area of Brgy. Waan 3. Freddie Adimat 8. Sapar Calihim were not covered in the said election 4. Maula Daridigon 9.

Minerva C. Taculin of CEO, Curtis C. Lazarraga of CHO, and Lucila R. Joven of CSSDO. rocess of the said election is quite unique from the contemporary election processes that experienc ed, where from a line-up a candidate will be chosen and will be experience, the Community appointed 25 individuals and from them they will select th e set of Officers (President, Vice President, Secretary, Treasurer, and Auditor) and nine (9) members of the Boar d of Directors. The process contributed to realigning community biases in choosing a particular group of individual s that will manage the BAWWASA. organization election has been fairly facilitated by Davao PMU who also took the role as the COMELEC. No. 17 (December 2008) Special Report of the Month (Part-II): Ass et Management; for an Effective Maintenance of Facilities Optimized Decision-Making (ODM) ODM has two definitions; i) a formal process to identify STEP 3: Apply strategies to individual assets and prioritize all potential solutions with consideration of Figure-4 shows the approach that can be used to l viability, social and environmental responsibility determine when a renewal strategy should be applied. and cultural outcomes, ii) An optimization process for Complete individual ODM for benefits and costs to considering and prioritizing all options to rectify existing identify the optimal treatment option or blend of or pot ential performance failure of assets. The process encompasses NPV (Net Present Value) analysis and risk assessment. On the ODM process incorporating predictive modeling techniq ues, there are five (5) steps. STEP 1: Construct generic model for a specific budget a decay curve using historical condition and failure records as shown in Figure-2. Where suitable records are not available, a decay curve can be developed using t he opinion of asst managers and operators with Life To date +5 +10 +12 +14 +16 Time experience in managing the assets. STEP-4: Determine strategy for asset Select the preferred strategy for an asset in accordance Written Down Value with the corporate policy for economic evaluation. Step-5: Carry out sensitive analysis Improved level of Service All economic evaluation involving forward projections inevitably bring a certain amount of risk and uncertainly. Because of the highly subjective nature of selection of parameters, it is possible to show the systematic variation Probability of Failure over a range of scenarios for each parameter in turn. A sensitivity analysis should be performed after completing the initial economic evaluation to rank variables in order : Determine optimal lifecycle strategy for assets oat different points in life Identify and evaluate the options available to ensure an asset is able to provide the required level of service. The critical issue for any logical project evaluation is to ensure that all treatment strategies have been considered. Depending on where an asset is in its lifecycle, some maintenance or renewal options may not be viable because of advanced asset deterioration. Figure-3 relates maintenance, rehabilitation and replacement to an asset's lifecycle of age.
