DEVELOPING AN INTEGRATED URBAN WATER MANAGEMENT MASTER PLAN FOR MARONDERA MUNICIPALITY
The overall project goal was to provide the Municipality of Marondera with an innovative and integrated approach that will ensure the sustainable management of water and sanitation for Marondera’s population. The project objective was to develop an Integrated Urban Water Management Master Plan for Marondera Municipality for a 20-year horizon which will pave way for sustainable management of water and wastewater in the Municipality of Marondera. The consultancy mainly involved the following:
(i) Undertook critical assessment of the status of water supply and sanitation infrastructure with a view to prepare de-tailed designs and detailed cost estimates, including drawings, bill of quantities and technical specifications in each case, based on a very limited budget given for this purpose.
(ii) Developed an Integrated Water Supply and Sanitation Masterplan for the management of water, wastewater and solid waste considering a 20-year horizon and possible scenarios of the extension of the town, including an investment plan for the short, medium and long-term horizons, undertaking full feasibility and detailed designs for the selected Master Plan option, and an Environmental Impact Assessment for the proposed investment projects. This will so include undertaking an economic appraisal for Marondera.
(iii) Developed a sub-catchment Water Resources Development Strategic Plan for the sub catchments directly impact-ing/impacted by the Marondera town. The tasks included an assessment of water availability, spatial and temporal demands, current and future storage, water allocation criteria, institutional systems and coordination, environmental impact, economic sustainability, etc. It will also consider how the system would be affected and respond to climate change scenarios. The sub-catchments included: Upper Manyame, Nyagui, and Macheke.
(iv) Undertook an institutional analysis, which would include reviewing the roles and responsibilities of the various stakehold-ers at local and national level and suggest ways to improve their interaction or coordination.
The Master Plan developed works including the rehabilitation and construction of new water supply and sanitation systems, raw water and wastewater treatment plants, sludge treatment systems, on-site sanitation systems, reuse of sludge and treated effluent and solid waste disposal. The investment plan is developed based on the priority of actions to solve issues related to water availability, urban development, socio-economic and environmental needs.
