Introduction The Metro Kalibo Water District (MKWD) has always put the safety of its concessionaires first, paramount to anything else. Since its inception in 1976, MKWD has assumed the role of the premier source of quality water supply in the municipality of Kalibo and beyond. Its continued growth has proven that putting quality and safety first can and will pay off. Because most if not all of MKWD employees are also part of its concessionaire population, MKWD has a finger on the pulse of what improvements can be made and undertaken in order to keep its services up to par with the expectations and satisfaction of the concessionaires. Over and beyond concessionaire expectation and satisfaction, MKWD has pledged to keep water services in top quality as well as ensure safety in the water delivered to the thousands of households it reaches. To further that aim, MKWD continues to find ways to augment and better its mission.

When the Department of Health (DOH) issued Administrative Order No. 2014-0027, requiring all drinking water service providers to develop and implement a water safety plan, and the Local Water Utilities Administration (LWUA) issued Memorandum Circular No. 010-014, directing all water districts and rural waterworks and sanitation associations to develop and implement a water safety plan to comply with the provisions of DOH AO 2014-0027, the MKWD pursued the mandate of the law in support of the objectives of the DOH and the LWUA, issuing Office Order No. 034, establishing a Water Safety Plan Team to tackle the development and implementation of the MKWD Water Safety Plan.

As per the WHO Guidelines for Drinking-water Quality - First Addendum to Third Edition, Volume I: Recommendations, “a water safety plan is a plan to ensure the safety of drinking water through the use of a comprehensive risk assessment and risk management approach that encompasses all steps in water supply from catchment to consumer.”

With that in mind, MKWD called on the primary players within its organization structure who have the greatest influence in terms of its water supply system. From the initial stages of planning a new water service connection to its preventative and procedural upkeep, members of the MKWD Water Safety Plan team are the same people who have intimate knowledge and experience with the entire system.

Through the MKWD Water Safety Plan, MKWD aims to further its mission in keeping concessionaires safe with quality water supply, ensuring that wherever MKWD water reaches, the product remains the same and compliant with concessionaire satisfaction.

2.7 CATCHMENT – SIX (6) DEEP WELLS The Metro Kalibo Water District draws water primarily from six wells (originally seven until the Palale Pumping Station was decommissioned due to high contents of iron and manganese). The wells have been in service from 12 to 34 years, With the oldest constructed in 1982. The shallowest well reaching a depth of 180 feet and the deepest at 220 feet.

11

2.7.A. LIBTONG PUMPING STATION

The oldest pumping station of MKWD nearly four decades now, the Libtong Pumping Station has been providing the Metro Kalibo Water District water supply system with an ample source of water. Sometimes in October 2000 operation has been stop due to occurance of turbidity which attributed by damage casing and later on undergo a rehabilitation through recasement of casing. In July 2006, a new well was drilled beside the original well location which increased its source capacity from 40 LPS

to 60 LPS at present. At a depth of 216 feet, the casing and screen are spiral and stainless, with cement grout at a depth of 22 m. Both the pumpbase and the pumphouse are in good condition and a perimeter fence ensures protection from natural threats.

2.7.B. TINIGAO DEEP WELL

The Tinigao Pumping Station has been providing water since 1991. Same with Libtong Pumping Station, the Tinigao Pumping Station has a depth of 216 feet, a spiral casing and stainless screen, and a 22-m deep cement grout. Both the pumpbase and the pumphouse are in good condition and a perimeter fence ensures protection from natural threats.

2.8 AKLAN RIVER (Bulk Water)

Since May 2015, in order to supply the growing number of consumers, Metro Kalibo Water District has started to purchase water from its bulk water supplier Datem Water, which sources its raw water from the Aklan River in Kalibo, Aklan, The objective now is to tap unused resource while preserving ground water for future use.Aklan River has a mean stream flowrateofabout27,40Cubicmeterspersecond,flowing

from the Albanian Mountain Range, and feeding its tributaries of Timbaban River and Dumalaylay River, towards the Sibuyan Sea. The river is used by MKWD as

a source of water to bolster its current water supply system through bulk water distribution by DATEM

2.9 TREATMENT

The primary disinfectant used for treatment is the chlorine gas (68kg/cylinders) at all source points and set-up with a back-up alternative disinfectant in hypochlorite granules.

2.10 WATER DISTRIBUTION The MKWD water distribution system spans the municipalities of Kalibo, Banga, New Washington, Balete, and portions of Batan, Also, it supplies water to Numancia,MakatoandLezothroughbulkwatersupplyvia Numancia Water District. Treated water is pumped, stored, treated and transported to the service areas by transmissionmainsinvariationofsizesandmaterials. The distribution system generally comprises of: a) transmission main, b) primary distribution lines, c) secondary distribution lines, and d) Seven tanks (reservoir)/sump and boosters. The transmission main is the main conveyor of treated water supply for distribution, from which the primary distribution lines (or sub-mains) are connected and span the main roads. The secondary distribution lines are connected to these sub-mains and laid along public streets. The water district was recipient of a loan package from LWUA in the amount of Php 4.8M

sourced from USAID for the construction of Phase I Interim. Improvement Program for source development and expansion programs. As the annexation of the Municipalities of Banga and New Washington was accepted on September 5, 1991 and March 5, 1992, respectively, the water district availed of Php 140.0M loan from LWUA sourced out from JBIC (formerly OECF) to financeits Phase II Improvement Program completed on 1999.

15

The water district, being consistent with its mandate, wasofficiallyre-categorizedfrommediumtobigwaterdistrict in February 1996. With the annexation of another nearby town in view and the various expansion projects accomplished, the water district was renamed to Metro Kalibo Water District on March 2002. The annexation of Municipality of Balete was approved on March 25, 2002. With the progress and development the district has so far accomplished, upgrading of Metro Kalibo Water District from big water district category to large category was approved on August 2003. On February 12, 2007, the annexation of three (3) barangays of Batan, namely Camaligan, Magubahay, and Caiyang (CAMACA) was approved.

2.11 DISTRIBUTION NETWORK 2.11.1 Reservoirs/Sump & boosters Reservoirs are used to store product water to augment the high water demand during peak hours of the day. Generally across the service coverage area, peak hours are between 6am to 9am and 5pm to 7pm. Sincethewell-fieldofMKWDcanbefoundalongtheAklanriveronlywhich is located in thewesternboundaries of the service coverage area. Sump and boosters are needed to transport/convey product water to the farthest barangays from the source.

This is more evident in the areas of Balete and Batan which can be found in the southeastern portions of theservicecoveragearea.Thisparticularareacanbecharacterizedbyrollingandundulatinghillswithelevationranging from 30m to 50m above mean sea level.

Hazards and RisksModule 3. IDENTIFICATION OF HAZARDS & HAZARDOUS EVENTS & ASSESSMENT OF RISKS

In identifyingthehazardsandhazardousevents,theWSPTeamnotedwhatcouldgowronginevery aspect of the MKWD’s water system from the catchment areas, through the treatment plant and distribution system, and to the consumer. The WSP Team had to “walk the system,” study records, and note relevant local knowledge in order to come up with reliable data from which potential biological, physicalandchemicalhazardsthatcanaffectthewatersupplywereidentified.

Hazardswereassessedandrankedusingthesemi-quantitativeriskassessmentmethodinordertostreamline the list of risks which need priorities. Table 1, as shown below, describes the semi-quantitative riskmatrixwhichtheWSPusedinprioritizinghazardouseventswhichposethemostsignificanthazardsand the highest risks.

VerificationModule 7. VERIFY THE EFFECTIVENESS OF THE WSP

VerificationshallbenecessaryinordertodeterminewhetherornotthisWSPisworkingproperly.Itinvolves three activities that are to be undertaken together to provide evidence of its effectiveness. These are:

• Compliance monitoring; • Internal and external auditing of operational activities; and • Consumer satisfaction.

Compliancemonitoringinvolvesconfirmationofcompliancewithwaterqualitytargets.Ontheotherhand, internal and external auditing of operational activities can be used in assessment and in checking compliancetorequiredstandards.Thefrequencyofauditdependsonthelevelofconfidencerequiredbythe MKWD and the regulatory body. Meanwhile, consumer satisfaction includes obtaining feedback from consumersiftheyaresatisfiedwiththewatersuppliedtothem.

Insum,verificationshouldprovideevidencethattheoverallsystemdesignandoperationiscapableofconsistentlydeliveringwaterofthespecifiedqualitytomeetthehealth-basedtargets.Ifitdoesnot,theupgrade and improvement plan shall be revised and implemented.Thetablebelowshowstherespectiveverificationmonitoringplanfortheidentifiedcontrolmeasures.

Management ProceduresModule 8. MANAGEMENT PROCEDURES

Clear management procedures documenting actions to be taken when the system is operating under normal conditions (Standard Operating Procedures or SOPs) and when the system is operating in ‘incident’ situations (corrective actions) are an integral part of the WSP. For standard operating procedures under normal conditions the approved Revised Operations Manual (Revision1) shall be used.For procedures due to incidents that breaches the critical limits as set in this water safety plan or on incidents of near misses the following procedures shall be followed: A. Incidents that breaches the critical limits B. Incidents of near misses

In such cases the following procedures shall be followed to institute the proper corrective actions: A. InvestigationandVerificationofincidentofresponsibledivision B. Documentation of incidents by the Water Safety Plan Team C. Automatic review of procedures D. Develop/Reiterate Personnel Training E. Calibration of support programs F. Calibration of Water Safety Plan On the other hand, in case of improvement or upgrade plans here are the prescribed management procedures: A. Annual Systems and Development review and recommendations shall be conducted every month of November B. AnnualreviewofVerificationprogramofWaterSafetyPlan The MKWD is in the process of developing and implementing its quality management systems. These processes shall be give special focus on the water supply operations and water service connections processes.

In cases of emergency, the Emergency Action Plan of MKWD shall be deployed and it will be guided by the Revised Operations Manual (Revision1) and this Water Safety Plan. In connection with the foregoing procedures the following communication protocols shall be followed:

Support ProgramsModule 9.

In support of the Water Safety Plan Development and Implementation the MKWD have committed a more holistic approach in its water supply operations. The continuous development and update of necessary and pertinentdocumentsliketheoperationsmanualandthecitizen’scharterarebeinggivenpriority.Thisyearthedevelopment of the MKWD Quality Management Systems continue to encompass all processes of the District with special focus on the water supply operations and water service connection services. In relation to the Water Safety Plan per se, the MKWD will be developing and implementing its program for the Integration of a Geo-spatial platform for the Water Distribution facilities and assets in the water supply operations. The activity involves the comprehensive mapping of the MKWD network with Geographic Information Systems. This will be developed with the end view of incorporating Hydraulic modeling of the system to monitor among others water quality issues. A Research and Development Program is also being eyed to provide MKWD for technical and data information with regards the catchment area of the Metro Kalibo Water District. To compliment all these developments a Program for the Training and Development of the MKWD employees to properly implement the Water Safety Plan

Revision of the WSP following an incidentModule 11.

Asoutlinedpreviously, toensure thataWSPcoversemerginghazardsand issues, itshouldbe reviewedperiodicallyby theWSP team.Aparticularbenefitof implementing theWSP framework isa likely reduction inthe number and severity of incidents, emergencies or near misses affecting or potentially affecting drinking-water quality. However, such events may still occur. In addition to the periodic review, it is important that the WSPisreviewedfollowingeveryemergency, incident,orunforeseenevent irrespectiveofwhethernewhazardswereidentifiedtoensurethat,ifpossible,thesituationdoesnotrecuranddeterminewhethertheresponsewassufficientorcouldhavebeenhandledbetter.

Aside from this regular review of the Water Safety Plan, mandatory review shall be performed within one week from any occasion of breach of any critical limits or near-misses of such. The following procedures shall be strictly followed in every such incident of breach and near misses, to wit:

INVESTIGATION AND DOCUMENTATION OF INCIDENTS

1. The Implementing Division concerned shall prepare an incident report to be submitted to the Department Manager/General Manager copy furnished the Water Safety Plan Team Leader. 2. The Water Safety Plan Group concerned shall gather and collate all the necessary papers and other documentation for the review of the WSP Team. If necessary, the group shall take pictures of the site of the incident. 3. The review shall be conducted within one week from the incident of breach or near miss. For the purposes of this module one week for the incident of breach shall mean, a week after the cessation of the breach of an operational limit and the application of the proper corrective action
