This poster outlines the features, results and lessons learnt from the city-wide survey that supports a Faecal Sludge Management Plan in the City of Jambi, Sumatra, Indonesia.
The survey, unique in its kind and scale, took an innovative and bold approach combining re-used technology, collaborative work, use of open source, free software, and governance mechanisms designed ad-hoc.
Its organisation and execution were very successful overall, considering the scale of the exercise, the first of its kind in FSM in Indonesia. The lessons learnt are valuable for other Indonesian and southeast-Asian cities.
The survey was planned and executed in the framework of the ADB and Australian Aid-funded Capacity Development Technical Assistance (CDTA) program of the Metropolitan Sanitation Management Investment Project (MSMIP), using funds available from the Water Financing Partnership Facility (WFPF) provided by the Bill & Melinda Gates Foundation.
The CDTA project team carried out a detailed survey of more than 40,000 households (equivalent to an estimated population of 185,000 inhabitants, i.e. approximately one-third of the total population of the city) in Jambi, Indonesia, with the objective of collecting the data to form the basis for the city’s Septage Management Plan (see supporting material).
The results of the survey were satisfactory both in terms of i) how the survey was planned and executed, and ii) the consistency and sufficiency of the data collected for its use it in the planning and decision-making processes of the Jambi Septage Management Plan.
The success of the survey exercise can be attributed to several key methods and tools:
- The surveyors and coordinators were all neighbours of the districts surveyed, under the guidance and supervision of the local leaders and the consulting team.
- An Android mobile phone application to record the answers given by the respondents, including the recording of GPS position, and a custom-made survey database. Both originally developed by IUWASH and jointly adapted to the Jambi project.
- The processed data were input to a geographical information system (GIS) using the open-source client application QGIS.
- A web-based portal application used to manage the implementation process of customer desludging services as well as disposal of sludge at the IPLT. Features available in the web-based Portal application are: development of customer database, desludging truck operator database, work order system and accounting systems. This application can also be used to monitor truck movement by displaying it with maps on the application dashboard.
See the supporting material for further details about the tools and methods used.
The exercise was the first of its kind in Indonesia, and there are many lessons that can be applied to other cities in the country and the region, among others:
- Leverage on previous work: Some of the core tools are adaptations of tools developed and used by IUWASH in previous projects in Indonesia. The project gained not only in efficiency, but also from building on previous knowledge.
- The use of spatial data visualisation was a fundamental aid for understanding and conveying important insights about the existing condition of sanitation facilities in the city.
- Data quality (including planning for data gaps and errors beforehand) deserves a central task to ensure meaningful outcomes.
