1. Introduction
A. Background
1. Inadequate access to a safe water supply is recognised as a significant cause of disease and child mortality in Timor-Leste. In October 2013 the Asian Development Bank (ADB) in partnership with (i) the Government of Timor-Leste (GoTL) Ministry of Public Works Transportation and Communications (MPWTC) and (ii) National Directorate for Water Supply (NDWS) signed a grant agreement for the project “District Capitals Water Supply Project Grant” to be financed by ADB and GoTL.
2. The Millenium Development Goal target for water supply for Timor Leste is to increase the proportion of people with access to improved water supply to 78% (from less than 50%). The dilapidated state of the water suply network in the district capitals at the commencement of this project meant that there was access to water for only a few hours every day for most of the population in Pante Makasar (Oecusse District 73%) and Manatuto (Manatuto District 51%). Prior to the commencement of this project more than a third of the population in Pante Makasar (37%) and Manatuto (42%) did not have access to a piped water supply from the National Directorate of Water Supply Services system (NDWSS). In addition to the direct effects on the health of town residents, lack of water contributes significantly to the burden on women; who spend time fetching water, managing home water supply and caring for children affected by water related diseases.
3. The District Capitals Water Supply Project aims to provide a safe and reliable water supply to the district capitals of Manatuto and Pante Macasar including rehabilitation of intakes and pipes and water supply infrastructure. The Grant, has not only benefited the local communities but also focused the attention of women and children in various locations by increasing their knowledge of water efficiency and safe hygiene practices.
4. In this reporting period this Project has been completed in Pante Macasar (Manatuto was completed in October 2016) and more people already enjoy improved supplies of drinking water. This should lead to fewer water related diseases, particularly in children under 5 years old. The NDWSS will now be able to provide a safe and more reliable water supply in the district capitals of Pante Makasar and Manatuto and lessen the workload on women. The Project is the first step in the GoTL plan to provide 24-hour access to safe drinking water in all district capitals. A summary of the works for both subprojects is shown in Table 1.1.

B. Description of Subprojects
6. DCWSP Manatuto subproject. The Manatuto subproject consisted of several improvements to water sources (called intakes) and upgrading of more that 40km of water transmission and distribution pipes. The Weten Spring No. 1 spring intake structure has been constructed to fully utilize that source which is located south of Manatuto next to the Laclo River. The Nunuli bore and Laclo Infiltration Gallery have been rehabilitated by restoring original pipelines in the gallery. The pipelines from Beklei spring are upgraded and continue as the water source for the separate water system in Aldea Obrato. The Base Camp service Bore acted as a standby source and supported the demand of Base Camp Service area during upgrading and maintenance work at Weten Spring. The combined yield of Weten Spring is enough to satisfy water demand requirement of the water system by the design year 2035; estimated at 34L-s.
7. By December 2016 the works for the Manatuto subproject were completed. The pumping facilities at Nunuli Bore and Nunuli Pumping Station have been replaced. New storage tanks have been constructed in the Beklei, Hatubela and Base Camp areas. Transmission pipelines and distribution pipelines have been installed. A total of 15km pipelines have been installed to connect to the Weten Spring and Beklei Spring Sources. About 26km of distribution pipelines have been laid to cover the existing service area and extend water service to adjacent aldeas. More than 1,000 service connections with water meters have been provided. This estimate is based on the total number of household in base year 2015 that will be served by the water system (subject to confirmation). Disinfection Facilities have been provided at Hatubela, Beklei and Nunuli to ensure the safety of water being supplied to the distribution system. Other provisions of the project include, public toilets at Obrato restaurant area and Maabat Cathederal area, procurement of tools, equipment and vehicles, operation and maintenance training.
8. DCWSP Pante Macasar subproject. The existing upland stream intakes of Pante Macassar and additional wells are the main water sources of the improvement plan. The existing water sources are the 4 surface water intakes called Meokana, Tulumopu, Tulubesi and Oetulu intakes and the Tono Well. Depending on yield these may be augmented later, if necessary. The Pante Macasar subproject consists of several improvements to water intakes and upgrading of water transmission and distribution pipes covering about 50km. About 6.8km of transmission pipelines with diameters ranging from 100mm to 200mm have been laid on the transmission network. A total of 39km of pipelines have been laid with diameters ranging from 50mm to 200mm on the distribution network of the 3 Pumping Zones. By December 2017 the works in Pante Macassar were complete. The plan included the following infrastructure and facilities. A new intake structure, constructed in Meokana about 200m from the existing water intake for easier operations with a 150mm conduit made of Ductile Iron and HDPE pipes. Tulumopu intake structure has been rehabilitated and fenced to prevent contamination and a new 100mm transmission line is installed. Tulubesi intake structure has been replaced with a new structure and the Oetulu intake structure has been rehabilitated and strengthened.

The Tono well which has reported discharge capacity of 9.6l-s will be used and an additional well has been drilled about 500m south from the existing Tono well. The new well is expected to have a discharge capacity of 10L-s - 15L-s. The pumping facilities at Tono have been replaced with electro-mechanical equipment complete with accessories, pump house, generator set, transformer and power line extension to ensure a 24 hour service. The additional well at Tono has been equipped with electro-mechanical equipment; complete with accessories generator set, transformer and power line extension to ensure a 24 hour service). By December 2017 the pump house was complete. Three new storage facilities have been constructed: (i) 250m3 bolted steel tank at Oesono; (ii) 250 m3 bolted steel tank to replace the existing 200m3 ground reservoir at Bairro Oetulu; and (iii) the new 350m m3 bolted steel tank at Samoro has been constructed about 80m uphill from the existing Samoro tank. Two new slow sand treatment facilities are included: (i) 15L-s capacity slow sand filter has been built beside the new Oesono tank; (ii) existing slow sand filtration in Oetulu has been replaced with a new 15L-s slow sand filtration apparatus. Water from both tanks will then pass through chlorination facilities prior supply to the service area. The existing Tono well and the new well have also been equipped with chlorination facilities. An Operation & Maintenance (O&M) building and warehouse have been constructed near to the Tono borehole facilities. More than 1400 service connections with water meters have been provided. This estimate is based on the total number of households in base year 2015 that will be served by the water system. All the proposed facilities are located within the footprint of existing facilities or on land owned by the government and the government agreed to provide the land at no cost.
C. Status of Projects
9. Environmental assessments were conducted for both subprojects and environmental management plans (EMP) were prepared. The environmental assessments and EMPs were approved by the National Directorate for Pollution Control and Environmental Impact (DNCPIA) and the licenses have been obtained for both subprojects in a timely manner. The status of the projects’ documents is shown in Table 1.2. The request for renewal of environmental licenses was passed to DNCPIA in August 2016. License renewal is automatic under Arrticle 24 of Decree Law 05/2011 the Environmnetal Licensing Law.
D. Institutional arrangements
10. The executing agency for the upgrading and improvement projects is the Conselho de Administração do Fundo Infrastrutura (CAFI) and the implementing agency is the MPWTC. The agency for implementation within MPWTC is the WATSAN Sub Project Management Unit (SPMU) established to manage and implement water and sanitation projects financed wholly or partially by GOTL’s development partners.
11. The SPMU was embedded in the MPWTC and is responsible for managing programs with financing from GoTL development partners, e.g. ADB. The SPMU is responsible for day to day management of the programs, including implementation of requisite safeguards measures on all subprojects.

Environmental License validity 2 years
12. Through program support, the SPMU recruited an international environmental safeguards specialist (IES) in April 2016 who is financed by ADB. The IES is responsible for ensuring compliance with safeguard requirements, environmental management and monitoring and capacity development for environmental safeguards within SPMU and for the subproject contractors. In practice SPMU has begun to accumulate some experience in dealing with the safeguard requirements of development partners and other government agencies.
13. The implementation of each subproject has been supervised by a team of consulting engineers known as the Detailed Design and Supervision Consultants (DSC). Within each subproject there was one construction contract package or component. Each component was managed by the DSC and undertaken by contractors. Each Contractor was required to have an officer to oversee environmental matters and health and safety and traffic control; responsible to supervise the workforce in the implementation of mitigation measures for environment, health, safety and traffic control as required in the EMP.
E. Arrangements for monitoring
14. The human environmental resources for environmental safeguards in SPMU comprised an international environment specialist (IES) responsible for the coordination of environmental management, environmental monoitoring and capacity development across all subprojects. The IES (intermittent) completed a 60 day contract to cover both subprojects and travel to and from Manatuto and Pante Macasar. The IES has liaised directly with the DSC’s Site Supervising Engineer (SSE) and the National Site Engineer (NSE) in both Manatuto and Pante Makasar. On some occasions the IES liaised with the Contractor if the DSC’s SSE or NSE are present at site inspection meetings. The DSCs SSE/NSE were required to perform the environmental inspections and keep a site diary for each contract. The IES mentored the SSE/NSE on each subproject in terms of environmental and safety awareness and liaised with them and the contractors Environmnet and Safety Officer (ESO) directly during site inspections; which also served to bolster “on the job” training.
15. The DSC was Korean Engineering Consultants Corporation (KECC); the same company for each subproject. The DSC’s Site Supervising Engineer (SSE-full time) on each sub-project was an international technical consultant and the NSE was a national consultant
Final Environmental Safeguard Monitoring Report, District Capitals Water Supply Project Page 6 Water and Sanitation Sub Project Management Unit, MPWTC, Government of Timor Leste : July 2017 to March 2018
(also full time). These were the key officers responsible for environmental management and monitoring for each subproject under their control. In practice there was one lead contractor and one or more subcontractors under each subproject. NSE has liaised directly with the contractors ESO on a daily basis. NSEs were asked to keep a site diary for each contract that they were responsible. The IES provided intrermittent monitoring for each subproject (usually two to three days every month) and mentoring for the NSE and training for the contractor staff (and subcontractors) as necessary.
16. The Contractor for Manatuto was Samhee Construction Company Limited (SAMHEE). The Contractor for Pante Makasar was Youngjin Construction Incorporated (YOUNGJIN). Each contractor was required to have an officer covering environmental and safety aspects. However the role of Environmnet and Safety Officer (ESO) is not a dedicated role for these subprojects and officers within the contractor’s work force wiith other responsibilities have taken the role of ESO for each subproject. The ESOs also oversaw basic site supervision and inspection duties. The officer taking on ESO duties liaised directly with and received instructions from the NSE or SSE; the IES has provided “on the job” training and refresher training as the projects have progressed.

2. Monitoring Activities
17. Strategy. In order to achieve consistency and harmonisation, monitoring was conducted in a similar way for both subprojects; by following the approved environmental management plan (EMP). Monitoring was conducted by visual observation and checking that the project activities are in line with the EMP; recording how mitigation measures are being implemented. The EMPs for both subprojects are similar. The EMP was intended to be updated by the contractors ESO in the pre-construction stage as the Contractors EMP (CEMP). In practice the contractors’ environmental awareness was very low. Therefore after review by the IES in April 2016, it was noted the EMPs prepared in the project preparation stage, that were based on typical construction methods, were adequate for use in both subprojects. Therefore the EMPs were found to be sufficient to control all foreseable environmental impacts and the EMPs were not updated. However the Consultants and contractors made a commitment to fulfill the requirements of the EMPs. The EMPs already contained a range of environmental mitigation measures that are sufficient to control project impacts. The EMPs have been continually under review and due to the interventions of the IES it was not necessary to improve on the EMP. The mitigation mesures in the EMP were extensive and represent core mitigation measures that can generally be applied to all water supply projects. Although the contractors’ environmental awareness is very low the core mitigation measures have been promulgated since the IES was engaged in April 2016 and continued to be applied to all aspects of the subprojects as they were completed. Figure 2.1: DCWSP Construction Stage Organization Chart
18. Methodology: The first stage of interaction was to provide environmental compliance and awareness training (ECAT) which was carried out in April and May 2016. However, even after significant training, experience showed that ESOs, SSEs and NSEs required considerable support from both SPMU and IES. Whereas the Contractors EMP (CEMP) has not been updated, the focus has been on making sure the SSEs and NSEs complete monthly environmental reports, supported by checklists and a summary. The environmental summary reports for each subproject have been included as an annex in the Monthly Project Progress reports for both Manatuto and Pante Makasar from May 2016. Project specific issues such as location impacts from various consruction works associated with the infrastructure facilities
Final Environmental Safeguard Monitoring Report, District Capitals Water Supply Project Page 8 Water and Sanitation Sub Project Management Unit, MPWTC, Government of Timor Leste : July 2017 to March 2018
(water mains pipe laying, construction of intakes, construction of storage tanks and boreholde drilling etc.) have also been included in the monthly monitoring summary.
19. Checklists have been prepared for the three key areas of project activities (Appendix 1). The General Checklist 01 is designed to be completed for all types of construction work on each monitoring occasion to identify the location and type of impacts that might not be controlled suficiently well. Checklist 02 is for the Contractor’s Compound (base camp) designed to be completed at least monthly. Checklist 03 is for the Health and Safety designed to be completed at least monthly. These three checklists were sufficient given the scale and location of works completed.
20. Results: The IES instructed the SSE and NSE to complete the checklists with the ESOs if the contractor does not do this voluntarily. Checklists were apended to the monthly progress reports in the environmental section.
21. If action was required the first case was to make a verbal request for action. The coverage of the checklists is presented in Table 2.1. After discussions and several periods of interaction with the DSC’s and with the NSEs by August 2016 it was agreed that, based on project experience to date, the checklists would likely be sufficient for the duration of the project.
22. Site Clean Up and Rehabilitation Plan (SCURP): A site clean up and rehabilitation plan (SCURP) was prepated for the Manatuto subproject (November 2016) as the works reached completion. The SCURP for Manatuto subproject was completed to the satisfaction of SPMU prior to the demobilisation of the Contractor in early December 2016. A SCURP was considered for the Pante Macassar subproject as the works neared 90% completion; but the contractor cleaned up all sites as the workes were completed and a formal SCURP was not necessary. Checklists are common to both subprojects and are presented in Appendix 1. Table 2.1: Environmental Checklists NUMBER TITLE CL 01 GENERAL MONITORING PROGRESS & ACTION CL 02 CONSTRUCTION YARD/CONTRACTOR BASE CAMP / OFFICE CL 03 HEALTH AND SAFETY
23. The IES and SSE/NSE refered to the EMP and checklists and instructed the ESOs as necessary. In practice the first case was to request action verbally and on-site with the operatives as an on-the job training. If this did not illicit an acceptabll improvement, written instructions to the Contractor could e issued by letter from the DSC / SSE. If verbal and written instructions from DSC SSE and NSE to the contractor did not achieve the necessary action then the IES could revisit the site and issue an corrective and preventatitive action request (CPAR) to the DSC to enforce on the contractor. In unusual circumstances (safety or danger) an instruction could be issued to stop work. However in practice contractors have responded well to verbal requests and issuing CPAR has not been necessary. In all cases the contractors complied with verbal instuctions either immediately or within a few days. The intermittent monitoring undertaken by the SPMU is presented in Appendix 2.
24. Participants in the monitoring. The IES, SSEs NSEs and ESOs all participated in environmental monitoring. Other staff in SPMU could also report back problems if they were observed. The ESOs and the NSEs worked with each other on a daily basis. The IES was present intermittently.
Final Environmental Safeguard Monitoring Report, District Capitals Water Supply Project Page 9 Water and Sanitation Sub Project Management Unit, MPWTC, Government of Timor Leste : July 2017 to March 2018
3. Capacity Building
25. Training. IES conducted group training and workshop activities (ECAT April 2016 in Dili SPMU for the Manatuto group and in Pante Makasar for the Oecusse group). The SSEs and NSEs were included and additional on site training sessions were carried out for moinitoring with the NSEs, to mentor the NSEs. IES also conducted intermittent training on specialist subjects as requested; including reference to monitoring procedures. There was no third paty monitoring for environment. The SPMU participants in the monitoring are indicated in Appendix 2.
26. Frequency of monitoring. The ESOs and the NSEs worked together on a daily basis and the NSEs kept site diaries and records of site inspections on the Checklist #1. The NSEs visited each site for a joint inspection with the IES; generally once per month at the beginning and less frequently as the works neared completion. The IES was prepred to make additional visits (every two weeks if necessary) in case new environmental issues emerged, however, this has not been necessary. The IES attended joint inspections with SSE/NSE and ESO. Unanounced spot insections could be carried out at any time by the NSE and IES, such as after heavy rain or earth tremors or if there was a complaint. Under normal operations the ESO was instructed by the SSE/NSE and IES to improve any EMP matters that need attention and improve mitigation as necessary. In practice interaction between the SPMU and the subproject contractors took place several times per month and environmental monitoring visits took place one or two days every month on average at the beginning and less frequently as the works neared completion. (Table 3.1).
27. Main activities. The main activities during monitoring are direct observations on site of the status of the implementation of the mitigation measurres in the EMP for each project. In addition there are monthly progress meetings held with the DSC during which environmental and safety matters are raised. The dates for the site monitoring undertaken by the SPMU is presented in Appendix 2. The monthly progress meetings are attendeed by the IES and SSE/NSEs and ESOs during which environmental issues and priorities are raised. For reporting issues such as preparation of monthly environmental reports and other reports, ad hoc meetings are arranged in SPMU, on site or DSC and contractors offices as necessary.

4. Works Completed and Works in Progress
28. DCWSP Manatuto. Manatuto District. By December 2016 100% of the distribution pipes in Manatuto were laid. Work on the Weten Spring #1 intake was completed after the initial delay; due to unseasonal wet weather from July to September that prevented safe access to the site. The Contractor completed work on the Weten Spring #1 intake the associated transmission line and installed bioengineering measures by November 2016. The Contractor completed work on the Hatubela Storage Tank and Public Fawcet by October. The Base Camp Storage Tank was completed in October and bioengineering works were installed in November. Work was completed on the Nunuli Filtration infrastructue. The Beklei Storage Tank and the linking transmission pipe were completed by October 2016. The Public Toilet at Obrato and the Public Toilet at Aitias was completed by November 2016. Figure 4.1: DCWSP works completed in Manatuto by December 2016
Final Environmental Safeguard Monitoring Report, District Capitals Water Supply Project Page 11 Water and Sanitation Sub Project Management Unit, MPWTC, Government of Timor Leste : July 2017 to March 2018
29. DCWSP Pante Makasar, Oecusse District. By March 2017 the majority of the distribution pipes in Pante Makasar were laid (Figure 4.2). The Contractor had completed work on the intake structures at Meokana, Tulumopu, Tulubesi and Oetulu and completed the the borehole at Tono/Samoro. Work on the warehouse at Samoro was also completed.
30. The new Tono well and pump house, new Samoro Tank and chlorination facilities, Oetulu slow sand filtration and storage tank and Oesono slow sand filtration and storage tank are all completed. Gate valves and valve boxes are completed. Sections of distribution pipework remaining to be installed in the last reporting period (awaiting coinfrmation of the adjacent road alignment and boundaries of construction to avoid disturbance) have all been completed. Pipe bridge crossings and additional distribution pipework are inslatted (Figures 4.2 and 4.3). Work has reached completion by the end of December 2017.
31. In a previous reporting period up to December 2016 another contractor on the adjacent construction project for the road widening (for ZEEMS) accidentally interfered with several distribution pipes (Appendix 5). The pipes had previously completed outside the limit of works for the new roads indicated bt the road consultants. Proactive information was provided by the SSE but the ZEEMS contractor alegedly working unsupervised excavated pipes in several locations. The affected pipe sections have now been replaced.

5. Monitoring Results and Actions
32. DCWSP Manatuto. Manatuto. The EMP has generally been well implimented in all areas. The improvement of the fuel storage area at the Contractor Camp requested in May/June 2016 was implemented in July 2016. The fuel was stored in a dedicated area with surface treatment to prevent penetration of fuel residues. The Consultant continued to complete site inspections using the monitoring checklists and reported environmental inspections on 89 days up to the end of the latest reporting period (Appendix 2). The Consultant also reported briefly (see Appendix 4 to the Monthly Progress Reports) from July. The ammendments requested in June 2016 were included. The completed Checklists for the relevant months have been attached in Appendix 4 to the Monthly Progress Reports from July to October 2016. There were no significant construction works after the end of October. The Site Clean up and Restoration Plan (SCURP) was prepared in November and the procedures were carried out by early December. No inspections of Manatuto works have ben made in 2017.
33. DCWSP Pante Makasar, Oecusse. The EMP was well implimented in all areas. Some improvement was needed and training was given for a more thorough approach to waste disposal; waste cement bags and garbage needed to be thoroughly removed from all work areas when works were completed. The Contractor Camp was generally in good order throughout. General waste materials and garbage were thoroughly removed from Contractor Camp before it was handed back. The Consultant has continued to complete site inspections on monitoring checklists and reported environmental inspections on 41 days in this reporting period (Appendix 2). The Consultant also reported briefly in Appendix 4 to their Monthly Progress Reports from July to December. On several occasions in the previous reporting period more attention was required from the Consultant SSE and Contractor ESO to ensure all operatives on all sites are wearing all neccessary personal protective equipment (PPE). This situation gradually improved. The reminders to the Contractor to provide sufficient drinking water for all operatives were also responded to satisfactorily. The consultant has maintained an acceptable standard for the Monthly Progress Report Appendix 4 (July to October 2017).

6. Summary and Conclusion
34. Summary. The monitoring and capacity development has generally proceeded in a satisfactory manner. The contractors and DSCs staff on both sub-projects were given awareness training on the policy, legal, and administrative framework and the requirements procedures and checklists to be used in environmental monitoring. No particular difficulties were encountered by the DSC during the monitoring even though the procedures were new to them. However for both contractors’, their ESOs did not have the general capability to compile substantial reports in English. Although it should be noted that whereas the NSEs required much help in compiling the albeit brief monthly reports, a modest standard was maintained over the course of the propject. Consultants have generally supported the SPMU well in trying to complete checklists and monthly monitoring reports. The documentation has been maintained in this reporting period. Due to the advanced stage of the works in Pante Makasar and the frequent changes in sub-contractors for different specalist tasks, the opportunities for additional training were limited and therefore training continued to be be given “on the job” by the supervisors, as far as practicable.
35. Limitations. Lack of ability of some contractor staff and consultants to work in the English language is a big concern for the monthly report writing so the reporting process was simplified as far as possible. However there has generally been good cooperation and prompt implimentation and correction of the mitigation measures when requested in the general work situation; despite the linguistic limitations. None of the contractors ESO officers have translators but in this case the ESOs for the Manatuto and Pante Makasar packages were both able to speak all the necessary languages including English. However the ESOs had other engineering and administrative responsibilities for their respective conctractors. Although ESOs had multiple duties, they were based on site and were able to make the necessary daily observations and instruct sub-contractors as necessary with regards to environmental and health and safety mitigation measures. Observations indicate that sufficient attention has been paid to implementing the EMPs in both sub-projects and there has been no major non-compliance with the EMP. Minor non-compliances have been corrected in a reasonable timeframe.
36. In general the time allotted for the intermittent environmental work by the NSE in the DSC seems to be just about adequate but their lack of English puts an additional load on the IES in the SPMU. It was not feasible for the Contractors to update the EMP given the Contractor’s skills. However by the completion of the project it was no great dissadvantage to either sub-project as the current suite of mitigation measures in the original EMPs was suffuicient to control all likely impacts and has the EMPs were generally well implimented.
37. Work in Manatuto was completd November 2016. Work in Pante Makasar was complete by October 2017. Sufficient environmental management was in place for a project of this scale and magnitude given the location and stage of completion of the works.
38. Communications on the Pante Makasar Component 2 have been adequate as the Consultant can speak the home language of the contractor (e.g. Chinese, Indonesian) as well as Engish and Tetum; and is able to provide technical / engineering training. This has facilitated communications both on-site and in meetings with all parties.
39. Outstanding Issues. Observations by the consultants continued in Pante Makasar from July to October 2017 to cover the remaining minor works. There are no outstanding environmental issues.
Recommendations. The systems and procedures for environmental management have generally achieved compliance with ADB requirements for Manatuto Component 1 and Pante Makasar Component 2. The strategy for monitoring and environmental awareness improvement can be considered to be rolled out on future projects for contractors and consultants, updated as necessary to take account of recent trends and developments and the targets for completion of works.
