Description
The overall scope of this consultancy assignment is to carry out a Study for Saline Intrusion and to develop a Ground Water Management Plan.
Saline water intrusion is a serious threat to the sustainability of the water supply of Nacala. Therefore a detailed groundwater management plan and model needs to be prepared to protect the groundwater resources from contamination. The saline water assessment will indicate where saline water currently is present in the well field areas. The groundwater management plan should include the development of a numerical groundwater model able to predict the intrusion risk at various abstraction rates in the different well fields. The plan should contain recommendations that will ensure maximum effectiveness and maximum sustainable abstraction without jeopardizing the water quality in the short and long run. The interference of borehole pumping on adjacent boreholes as well as the other well fields should be investigated and reported on with operation requirements if needed. The Consultant should propose the activities required to collect the information that needs to be used as input to the groundwater model. The goal of this study is to protect the quality of the Nacala public water supply water by preventing seawater intrusion through the development of a groundwater management plan to operate with maximum effectiveness and maximum sustainable abstraction without jeopardizing the water quality. With many boreholes already drilled and not all of them used as production boreholes, the Consultant is required to use as far as possible the existing boreholes for monitoring of water levels.
The following Output Documents will be required to be prepared in accordance to the Consultant’s Responsibilities.
• Hydro-geological Data and Inception Report
• Preliminary Groundwater Management Plan and Aquifer Model
• Aquifer Model Monitoring Manual and Training of Staff
• Three two monthly Monitoring Review Reports
• Refined Management Plan and Aquifer Model in Excel or Access
• Final Groundwater Management Plan and Aquifer Model
