The Mainstreaming and Integrated Water Resources Management approach for More Resilient Basins in Mozambique \[MozWateR\] is a geared project towards achieving water security and safety by supporting Mozambique in developing its capacity to implement effective integrated water resources management (IWRM) in key basins in the northern and central water administration regions and improve capacity at a national level. This project is a collaborative effort where joint action on the ground will produce critical lessons from tried best practices that inform policy which strengthen business approaches, institutions, and rules around the sustainable use of land and water. MozWateR is being implemented collaboratively with the Northern Regional Water Administration (ARA-Norte), Central Regional Water Administration (ARA-Centro) and the National Directorate for Water Resources Management (DNGRH) as primary Implementing Partners (IPs) to combat several challenges in the national water sector.

Implementation of the construction project for the Zembe dam located in the Macate District, Manica Province. The works include the construction of the dam structure and auxiliary water utilization infrastructure.

The construction of the dam has the following objectives:

i. Improved threat management and disaster risk reduction;

ii. Promote and reduce small-scale crop loss, especially of vegetables and legumes, during periods of drought;

iii. Ensure the availability of water for domestic use;

iv. Other social activities.

The proposed location for the dam is situated in the Búzi River basin, specifically along the Mucessa River, at coordinates 19°16'25.70"S and 33°21'15.24"E, in the Zembe Administrative Post, Macate District, Manica Province.

 From a geological point of view, rock outcrops are observed in the bed of the identified section, but not on the slopes.

 Regarding the valley's morphology, it is a narrow and shallow section, with a maximum estimated depth of about 4 meters, suitable for dam construction. The valley is relatively closed in the area of the dam's axis and slightly more open upstream, a condition favorable to achieving a good water storage capacity.

 From a hydrological point of view, it is noteworthy that the river has a constant flow throughout the year, associated with the presence of relatively dense vegetation on its banks and low levels of sedimentation. This fact indicates that the watercourse does not transport large quantities of sediment, thus contributing to the longevity of the reservoir and reducing the need for frequent maintenance interventions.

 Regarding accessibility, the site is located less than 5 km from the headquarters of the Administrative Post, with viable access for vehicles, which facilitates the mobilization of resources during the construction phase.

According to the classification of Wladimir Köppen, the climate covering the District and the locality in question is of the humid temperate type. With an average annual rainfall of approximately 1,501 mm according to data from the meteorological station of Espungabera and average annual reference evapotranspiration of around 1,170 mm; the rainy season occurs mainly from October to April, with the highest rainfall recorded between December and March. Statement of Requirements for the Zembe Dam Construction Project, February 23, 2026

4\. Socioeconomic Impacts

The section chosen for the dam's construction is located upstream from communities and agricultural production areas, enabling gravity-fed water supply. The construction of this infrastructure will boost agricultural activity, with a special focus on vegetable production, as well as contribute to meeting the domestic water needs of the adjacent population.

This component will benefit approximately 1500 people and irrigate about 15 hectares.

The main crops grown in the region under rain-fed conditions are maize, sorghum, and beans. Irrigated agriculture is practiced, but on a scale far below its existing potential.

The Project consists of the execution of works, comprising the following:

i) A dam: this is an infrastructure with a reinforced concrete waterproofing core, with a vertical upstream face, embedded 2.00 meters deep in the natural ground. The downstream face will also be vertical and will be supported by buttresses and steps of mortared stone, embedded on the horizontal slab, which constitutes the dissipation basin, duly treated and prepared for this purpose. The crest will extend for approximately 40.00 meters, with a maximum height of 4.00 meters, where a central rectangular spillway 16.00 meters long and 0.60 meters high will be incorporated. The spillway sill will be at a height of 3.40 meters.

ii) A water intake well: this is a structure approximately 4m deep and 2.3m in diameter, as can be seen in the drawings, to be built to allow the extraction of water stored in the reservoir. This structure includes not only the well but also the "kit" consisting of the submersible pump and the solar power system. The solar panels should be placed on top of the elevated tank tower. This will have pipes inside, the bottom one of which will be split to ensure water enters the bottom of the well. The well must be built in a location and at an elevation that allows it to be recharged by percolation of the water stored in the reservoir through the soil.

iii) An elevated deposit: this is a metal structure approximately 4m high, to be built to accommodate a 5000l tank on top, allowing the fountain and drinking troughs to be fed by gravity.

iv) Two fountains: this refers to a solid block masonry structure designed to provide convenient and safe access to water for people. The project includes the concrete and block masonry structure, plumbing fixtures from the elevated tank, and a 1m diameter drain to keep the area dry.

(v) A laundromat: this refers to a metal-framed shed, covered with sheet metal, equipped with six laundry tubs and a clothesline, as shown in the drawings.

vi) A drinking fountain: this refers to a rectangular, ground-level tank with two cells, measuring 10m in length and 1.6m in width, to be built to facilitate convenient and safe access to water for livestock.

The construction is expected to last 120 days, starting from the date the contract is awarded and the corresponding work handover document is signed. The Contractor must submit a detailed schedule of the construction work, including its distinct phases.

A project with a perfect finish, free of any cracks or chips, and with the appearance of well prepared concrete.

With the implementation of this project, it is expected that the availability of water for irrigation of agricultural fields and watering of livestock will be guaranteed, thereby improving the lives of local populations.

This venture could boost small-scale production of fruits and vegetables for food and provide family income through the sale of some products.

It is expected that, after construction, the dam will fulfill its role of retaining water and contributing to the balance of climate variability.
