Expanding Water Supply in Informal Settlements in Jakarta, Indonesia
The problem
Many low-income communities in Jakarta relied on informal providers for water, because it was not financially viable to for the private company running the water network to connect them. The supply from informal providers was expensive and low quality.
How we helped
Castalia designed a subsidy program to make service expansion to low income communities profitable. The private concessionaire would receive a fixed payment per connection added in specified low-income communities. To design the program, we estimated the cost and revenue implications of expanding service to these communities used a discounted cash flow analysis to determine the subsidy amount that would make the investment in service expansion viable.
Impact
The program was implemented in 2007. Over 5,000 poor households were connected to Jakarta’s piped network within the first 3 years.
