Expanding water and sanitation access to the rural poor and increasing sanitation coverage in urban centers are the biggest challenges for Paraguay water supply and sanitation sector today. For this reason, the Government of Paraguay has requested support from the World Bank for a new comprehensive Water and Sanitation Sector Modernization Project (worth US$60 mln.) to include not only rural but also urban water and sanitation investments, support for improving sector governance, as well as planning and policy making.
The World Bank, Inter-American Development Bank and the National Environmental Sanitation Service (SENASA) have decided to evaluate the impact of water access to rural communities in Paraguay. By establishing a strong correlation between water sanitation and health indicators, they aim to strengthen resolve of the country's government to provide access to water service in rural Paraguay.
The impact evaluation study seeks to identify and measure the causal relationship between the access to potable water to rural communities and a set of health and development short-term and medium-term outcomes. Some of the short-term impacts to be studied include reduction in physical injuries that result from water fetching activities (i.e. back problems, miscarriages, etc.); reduction in the incidence of waterborne diseases and parasites (and their symptoms); reduction in child mortality and morbidity. General medium-term outcomes include an increase in the time dedicated to income generating activities, especially for women; improved health and nutrition; increase in work attendance; productivity and income generation; increased time dedicated to child care, and improvement in school attendance and performance.
The impact evaluation targeted 4,490 rural households (22,832 individuals) belonging to the treatment and control groups. The main approach consisted of a randomized trial technique.
The baseline data collection started before the implementation of the first phase of the treatment. It was carried out between March and July 2011. Questionnaires were applied to measure various socioeconomic and health characteristics.
The follow-up to the baseline survey will be held in fall 2013 after results from the preliminary assessment are disseminated. The second follow-up survey is scheduled for fall 2015.

Sampling
The National Environmental Sanitation Service (SENASA) has pre-selected a group of 400 communities, which will receive support in the construction and management of their water distribution systems. However, SENASA's physical and human capacity constraints limit the implementation of the program to at most, 100 communities per year. Inevitably, it would take SENASA four years to serve all the pre-selected community candidates. The counterfactual identification strategy consists of using a public lottery to randomly distribute the communities into four different groups. Each group will receive the intervention in subsequent years; the 100 communities intervened during the fourth year will serve as a Control Group for the 100 communities (the Treatment Group) reached in their first year.
To obtain a preliminary result on the potential effects of the access to potable water, an "external" group was selected to be part of the baseline. This external group comprised of a sample of 1,500 households belonging to 100 communities where the water distribution systems were already implemented at least two years before implementing the baseline. These communities were selected using a matching approach based on distance to the communities in the internal groups and some basic characteristics at the community level. The results of rural households that currently have access to potable water with those who do have not received this service will be compared using matching estimators in order to understand the impact of this treatment (the water system).
