Data on Water and Sanitation
The Zambia Compact is comprised of interventions to the water, sanitation, and drainage infrastructure in the city of Lusaka. The goals of these interventions include reducing poverty through economic development, decreasing the incidence of waterborne and water-related diseases, and generating time savings for businesses and households. To evaluate the impact of the Compact interventions the following evaluation questions were developed by MCC, MCA Zambia, and CDC. Health · What are the health benefits attributable to each type of Compact activity? Safe Water Supply/Consumption · What are the current consumption rates of safe versus un-safe water consumption and usage? · Do Compact activities lead to an increase in safe water consumption? Economic and Social · Do households experience an increase in income due to Compact activities? · Are households able to afford household connections, toilets, and water bills? · Were subsidy provisions adequate for sanitation connections? · What is the probability of finding work for beneficiaries? · What are the time and cost savings/use attributable to each Compact activity? Flooding · Is there a decrease in the frequency, intensity and duration of flooding? · Is there a decrease in property damage and loss of business caused by flooding? · Is there a decrease in travel time due to reduced flooding? Given the cause-and-effect nature of the Compact as described in the logic model, CDC recommended an impact evaluation as the most appropriate method to evaluate the effect of the interventions. The impact of interventions to extend water supply and sanitation networks to residential areas will be evaluated by comparing pre and post outcome measures in both intervention and control (counterfactual) areas.
