Background

As part of its Millennium Development Goals, the government of Timor-Leste targeted increasing access to safe water in the urban areas from 72% in 2001 to 86% in 2015. For the capital city of Dili, it targeted providing 24-hour water supply to 80% of the population by 2015 from 25% in 2007.  To achieve these targets, it set out to rehabilitate the tertiary network and water connections, initially in three subzones in three of the 10 Dili zones, with plans to eventually expand to the remaining seven zones.  Against this backdrop, it implemented the Dili Urban Water Supply Sector Project, approved by the Asian Development Bank (ADB) for a grant of $6 million in December 2007.

During project preparation, no water billing was undertaken by the National Directorate of Water Services (DNSA), and consumers were making no payments for water. This was to be addressed by the project, which aimed as outcome improving the management and tertiary distribution network of the Dili Water Supply System.  The improvements were to result in the reduction of non-revenue water (NRW) from 95% to 40%–50% in the whole city and 25%–30% in the project zones. The outcome was to be achieved through three outputs: (i) water losses reduced and controlled in three target zones; ii) visible leaks reduced through practical improvements and by refurbishing, replacing, or installing new stop valves and metering commercial customers; and (iii) leak detection, leak reduction, distribution planning, and distribution management skills of the technical and operations and maintenance (O&M) staff at DNSA upgraded.

To achieve output 1, connections were improved, pipes were replaced, and water control valves and meters were installed. These improvements led to NRW reduction but only for a short period, as soon after the physical works were completed, clamor for similar improvements in the seven zones outside the project coverage broke out, prompting the government to open the water control valves, resulting in the decline of water pressure and service delivery and quality. The initial improvement in billing collection also subsequently declined. Inadequate revenues and O&M funds, along with a maintenance regime that prioritized critical repairs only, spawned the continued deterioration of project assets, with consequent early major damages to key infrastructure in some parts of two of the three project zones.

For output 2, system-wide repairs were prioritized.  Visible leaks and open pipe discharges were identified, but completed only in 2013–2014.  Seven bulk meters were installed, and chambers and valves were rehabilitated or replaced albeit late and in lower numbers than planned.  The metering coverage of large customers in all zones likewise did not reach the 80%–90% target. Chlorination dosing units were repaired and replaced.

For output 3, the project tapped into the $1 million Dili Water Supply Performance Improvement Technical Assistance (TA) provided by ADB for the conduct of trainings to improve DNSA management, human resources, and technical capacities to maintain the new network systems and enhance meter management and customer service systems. However, in many cases, the knowledge and skills imparted through these trainings were not utilized as the project activities they intended to support had not even commenced by the time the TA closed in March 2011.  The loss of trained individuals further eroded the benefits planned to be delivered through the linked TA. 

Overall, the subzone approach demonstrated what could be achieved with a focused investment and support services, and this resulted in an increase in service, billing collections, and revenues. However, for the approach to work there needed to be a phased and planned investment in the other subzones, which did not occur.  With consequent actions accelerating the deterioration of infrastructure and services, the project failed to reduce NRW at levels planned at appraisal.  An assessment undertaken by the Japan International Cooperation Agency of the Dili water zones in 2015 indicated that NRW losses ranged from 70% to 95 % across the ten zones. For the project zones, NRW ranged from 70% to 95%.

The project had the MPW as executing agency and the DNSA as implementing agency.
