Conducting comprehensive baseline assessment of water loss at physical and commercial losses in Wonosobo District

 

  1. BACKGROUND  

Water.org is an international non-profit charitable organization based in the US.  It has field or country offices in 13 countries which includes Indonesia.  Water.org is focused on promoting wide access to water and sanitation services, especially toward poor households, or Base of Pyramid (BoP) households. Water.org works with partner organizations in various countries including microfinance organizations and water utilities. The purpose is to help these institutions promote water and sanitation loans or water connection financing services (in the case of water utilities) to BoP households.  

Perumda Air Minum Tirta Aji Kabupaten Wonosobo (PDAM Wonosobo) is a regional water utility mandated to provide piped water services throughout Wonosobo Regency. Currently, PDAM Wonosobo serves approximately 33% of the Regency’s population of one million, leaving more than 106,000 residents living in extreme poverty without reliable access to clean water services. The proposed intervention shall be implemented through three phased components: (i) Diagnostic and capacity building, consisting of intensive training programs for branch personnel to address existing technical and operational capacity gaps; (ii) Financial facilitation, including optimization of key performance indicators (KPIs) and direct assistance in securing favorable financing and repayment arrangements with financial institutions and/or service providers; and (iii) Impact evaluation, aimed at measuring outcomes through reductions in water loss, increased recovered water volumes, and expanded service coverage.  

The primary strategy to optimize the existing water supply system is to upgrade production and reduce water losses. However, PDAM faces two distinct hurdles: 

  • Infrastructure: PDAM recognizes the urgent need to replace aging pipelines. 
  • Capability: The team’s current ability to manage physical water loss is at its limit. PDAM required specialized technical support to move beyond basic repairs to sophisticated, data-driven water-loss reduction. 

 To avoid this stagnation, a strategic assessment to determine which projects can be covered by PDAM funds and which require external funds. We specifically seek support in water loss management to ensure that our limited equity is spent on a system that is efficient, modern, and ready to scale. 

2. SCOPE OF WORK  

Water.org intends to engage a consulting firm as consultants with previous experience of working with PDAMs. Previous experience of assessing development work around water would be an advantage. The selected consultant will be engaged to provide services on “Conducting comprehensive baseline assessment of water loss at physical and commercial losses in Wonosobo District”   

The report at least consists of: 

  • Result of the analysis of the existing business plan and an existing annual plan (RKA) to align with NRW reduction initiatives 
  • Baseline the review of performance or service quality, especially pressure, service hours, water quality, average consumption of domestic customers, and NRW. The baseline will include map existing assets and identify leak-prone zones, analyze physical and commercial losses, review financial capacity and investment potential as well as capital requirement for implementing NRW reduction projects and source of capital.  
  • Execute a pilot system diagnostic to establish accurate performance baselines, including analyzing investment capability for addressing both commercial and physical water losses, and provide a roadmap for accessing capital, evaluating options from lenders and technical providers who offer integrated financing and Water Loss Reduction expertise.
