Total Level of Effort: 50 days LOE
Location: Tangerang

Background STTA Assignment
Under Partnership of Agreement between The Government of Kabupaten Tangerang with IUWASH, mentioned that Government of Kabupaten Tangerang and IUWASH share common roles in an effort to improve urban water and sanitation. One of the common role is IUWASH provide technical assistance to Perusahaan Daerah Air Minum  Tirta Kerta Raharja (PDAM TKR) Kabupaten Tangerang, an entity that owned by The Government of Kabupaten Tangerang. One of assistance that can be provided by IUWASH is the study of distribution pipe network analysis in Service Areas 1, 2 and 3.

PDAM TKR has 120,780 customers (March 2014). PDAM TKR plans to increase service coverage and develop services in Service Areas 1, 2 and 3, where customers are mixed from low-income communities, housing estates and commercial customers. In these areas, PDAM TKR will increase about 24,000 customers. For the above plan, the addition of water capacity will be required. The addition of water capacity will be filled by uprating of 300 liters/second of the WTP Cikokol (from 1,275  liters/second will be uprated to 1,575 liters/second). The WTP uprating will be implemented and financed by private partner of PDAM (PT. Tirta Kencana Cahaya Mandiri). 

With the large increase in the number of customers and also with low pressure and high in NRW number (35%) condition, it would require a study of distribution pipe network analysis in Service Area 1, 2 and 3. This study will be conducted to determine the ability of the existing piping network conditions in areas of study related to additions of 24,000 customers. This study is also to determine what steps needed to reduce the number of NRW. PDAM TKR is committed to implementing what will be recommended by the study. PDAM TKR will finance it with its own funds.

To optimize the planning and development of existing primary and secondary distribution pipeline network of PDAM Tirta Kerta Raharja Kabupaten Tangerang in Service Area 1, 2 and 3 in anticipation of additional 24.000 customers and to support their plans to increase production capacity of water, so the water distribution services to customers can be improved and better to meet the applicable standard of good quantity, quality, continuity and water pressure.

The scope of work of this activity consists of:
1.     Task I : Preparation
    • Conduct preliminary discussions with IUWASH and PDAM TKR Kab. Tangerang  in order to prepare a work plan and report of the preliminary work
