Before designing any project, understand how your local river and groundwater catchments are connected (or not) and how they feed local water supplies or ecosystems. Baseline condition data will inform a feasibility study on the project approach.
The feasibility study will determine the quantity or quality of water needed, helping the project conserve time and resources. The feasibility study will also help to identify any risks, opportunities, or assumptions in implementing the work, so that these can be managed from the start of the project. Finally, the feasibility study will determine whether an engineering approach is sufficient, or if the project will also require a “soft skills” component to guide the local community on necessary behaviour change.
Attempting to implement a project without a thorough understanding of these elements risks damaging the credibility of the partnership.
As part of the Lusaka Water Security Action and Investment Plan (WSAIP) in Zambia, the LuWSI partnership wanted to increase the city’s awareness on ground water pollution and access to water and sanitation. The partnership commissioned a hydrogeological study that examined Lusaka’s public water supply wellfields and of 121 boreholes around the city. The study helped LuWSI to understand how the groundwater beneath Lusaka flowed, and where to protect this water from surface contamination by human or commercial waste.
The partnership was unable to install sewerage pipelines across the city due to financial constraints and the current status of the unplanned peri-urban areas (informal settlements had no legal entitlement to sewerage). Understanding the vulnerability of the groundwater to surface contamination in different parts of the city helped the partnership propose the solution of centralized facilities instead. Rather than disposing of waste at multiple domestic households using septic tanks or soakaways, waste is taken to a central point and disposed of safely. This approach helps protect the groundwater supply for drinking water and commercial purposes while still scaling up access to adequate sanitation across the city.
