Eswatini

Groundwater Monitoring and Installation of Solar Powered Pumps at Selected Localities

The Eswatini project focuses on resuscitating of the old groundwater monitoring system that due to climate change and drought, was converted into the water supply system. The project also acknowledges the intensified need for monitoring and increased access to water supply amidst the challenges of climate change. The project will install six monitoring stations in hotspot areas in the Northern Hhohho region. The Northern Hhohho region was identified as critical because it hosts new mining industry developments which have impact on groundwater quality and other social water needs. The project will also investigate the potential to use solar power for borehole schemes to benefit communities and rural schools.

The project will include the following key activities within Lomati and Mbuluzi River Basins:

  • Monitoring of existing selected wells (10 sites)
  • Development of new wells
  • Installation of solar powered pumps at selected sites
  • Installation of three micro-solar pumping systems at selected schools
  • One micro-solar energy driven rural community energy supply scheme

Approximately 5000 people will benefit directly and indirectly from the project, including local schools.

Lesotho

Expansion of a National Groundwater Monitoring Network

The objective of the project is to expand the existing groundwater monitoring network to form a comprehensive nationwide network for the support and guidance of groundwater management activities in Lesotho. The project is therefore designed to improve the availability and reliability of groundwater data required for appropriate management of groundwater resources and development planning in the country. The current monitoring, maintained by the Department of Water Affairs is limited and is not able to provide a full picture of the state of groundwater in the entire country, drilling of additional monitoring boreholes will help resolve the problem.

The following are the project activities:

  • Conducting a desktop study on the existing groundwater monitoring network
  • Geophysical investigations and siting drilling points in target areas identified during the desktop study
  • Drilling of additional monitoring boreholes
  • Calibration and installation of data loggers in selected boreholes
  • Monitoring of software and laptops
  • Training of Department of Water Affairs personnel
  • Initial monitoring

Malawi

Water Supply project in Chimbiya, Dedza District, Malawi

The project will explore deep aquifers by drilling a 100m deep borehole, equipping the borehole with a motorised electric pump, reticulating the water to ten communal-style distribution points around the community, culminating in supplying water to approximately 15 000 inhabitants in Chimbiya trading Centre.The project will compliment Government of Malawi’s agenda of providing safe portable water to the citizens. The project will also provide a basis for understanding deeper wells and hydro-geological analyses of the groundwater of the area for recommendation of appropriate abstraction models for human consumption. Chimbiyais one of the areas where the deep-seated aquifers were discovered. With this discovery it was believed that exploring deep aquifers could make water available to the community throughout the year in the face of climate change. The project is anticipated to serve more than 20000 people that include school going children, teachers, business people, farmers, religious leaders and the police working in the area.

The project activities include the following :

  • Assessment of the aquifer
  • Designing of the system using the data collected during the assessment
  • Water Source Development: this phase will require hydrogeological surveys to be carried out in the exploration of the groundwater and siting of the boreholes
  • Construction of structures – treatment house, solar panel rack, erection of tank towers, construction of tap points with standard aprons and all associated civil works for the sustainability of the project
  • System installation – mounting of the water tanks onto the towers, trenching for pipelines, installation of the treatment units, pumps, solar panels, electrical control units and taps.
  • Community Mobilization – engage the community to move them towards contributing to the success of the project
  • Safe Water Committee Education – train the elected committee on various sustainability of the project.
  • Wash Promotion – community will be trained on sensitization with respect to health and hygiene so that the risk of water borne diseases is reduced.
  • Commissioning – Once the project has been fully installed and in operation; there will beneed to commission it along with all key stakeholders including the Government of Malawi and SADC GMI to celebrate along with the community.

The project seeks to achieve the following outputs:

  • Controlled abstraction of groundwater

  • Trained community in Community Based Management of the water system that will include training in sustainability mechanisms according to tested success standards

Expected Project Outcomes

  • Improved availability of quality water resources for people of Chimbiya
  • Reduced cases of water borne diseases amongst the locals through provision of safe treated groundwater water
  • Improved attendance and consequently performance of school children
  • Reduced waiting time at the existing boreholes

Mozambique

Transformation of a dispersed Source in Water Supply System and Promotion of Hygiene and Sanitation

The objective of the project is the construction of the Water Supply System from groundwater abstraction in the village of Muchocolote in the PA of Catembe Simbe in the Matutuine district of Maputo Province.The community is currently using a handpump to abstract the water from the borehole. A submersible pump which will be powered by a solar panel will be installed to supply water to 2000 people.

Transformation of a dispersed Source in Water Supply System and Promotion of Hygiene and Sanitation

The project entails replacing the handpump with a submersible pump and constructing a 12-meter-high tower on top of which two 10 000 litres water tanks will be installed. Solar panels will be installed and used as an energy source for the water pump. Water from the tanks will be distributed to three different villages via three different subterranean pipelines (40cm below ground) with a radius of 6km. There will be a tap at each of the 4 villages to reduce the distance locals have to travel to access water. The community will be responsible for the maintenance of the water network.

Zimbabwe

The project seeks to characterise the aquifer system and set up a groundwater monitoring network system in the Greater Harare. Overally, the aim of the project is to catalyse improved groundwater management for the benefit of the diverse stakeholders in the Upper Manyame catchment, currently and into the future.   The project seeks to: quantitatively determine the available groundwater resources, determine the flow patterns, aquifer dimensions; fluxes; aquifer heterogeneity, and quality status. This will provide the data necessary for projecting groundwater availability in the future under climate change, land use/land cover change and growing demands due to population growth and urbanization. The research will explore how scientific tools such as groundwater models and 3D – stratigraphic tomography can be used to better explain groundwater dynamics to the groundwater managers, the users and policy makers.
