2009–2010 GLAAS survey
The 2010 GLAAS integrated and analyzed data from several different existing sources, including global data on sanitation and drinking-water coverage, donor aid flows, economic and development indicators, health indicator data, and data from regional sector and multi-sector assessments. In addition, the 2010 GLAAS involved a data gathering process at both country-level and donor organizations to fill key knowledge gaps. This data gathering effort took place during late 2009 and early 2010.
To avoid duplication of effort, data collection at countries occurred in full collaboration with other international partners. For instance, in Africa the data collection was performed in collaboration with the World Bank's Water and Sanitation Program Country Status Overview (CSO) initiative, and in Asia with UNESCAP Water Security initiatives. Countries were requested to formally participate through WHO country offices and through their respective government contacts.
For nearly all sub-Saharan African countries, the following country survey questionnaire was used:
For all other countries, the following country survey questionnaire was used:
External support agency (ESA) survey
To address information gaps concerning external development aid, the 2010 GLAAS also included a data gathering exercise at bi-lateral and multi-lateral donors, NGOs, private foundations, and international agencies. This data gathering effort recognized that a large amount of aid flow data is already available through existing sources. WHO worked in close collaboration with the Organisation for Economic Co-operation and Development (OECD) to make the best use of existing sanitation and drinking-water aid flow data, as most donors report to the OECD Creditor Reporting System (CRS).
For external support agencies that already report sanitation and drinking-water sector aid flows to the OECD Creditor Reporting System, the following questionnaire was used to augment existing data:
For external support agencies that do not report aid flows to the OECD Creditor Reporting System, the following questionnaire was used to collect information:
