Contract Value: 782,917.05 USD

The main objective was to create a connection between the results produced by the Shire River Operation Decision Support System (ODSS) software and the KABOM (Kamuzu Barrage Operation and Management Model) management tool so that the hydrological information produced and data collected by the ODSS can be directly in-gested into KABOM to improve and facilitate decision support. It is specified that in the initial phase of implemen-tation, the tool’s functionalities were kept the same as those of the currently implemented system, thus upgrading the software used and connecting it to the ODSS. Subsequently, the need and possibility of adding new features to the tool were also evaluated. Another improvement resulting from the connection with the ODSS software is the more precise definition of the amount of resource coming from the tributaries, which in this case can be directly calculated by the hydrological model instead of being limited to the choice of low or high parameters.

The provided services covered the fields of:
I. Improving the web dissemination platform for informing the public and stakeholders on flooding;
II. Improving the data collection database system (data sharing);
III. Improving the link between Kamuzu Barrage Operative Management and the ODSS;
IV. Improving the existing flood and flow forecasting system for Lower Shire River sub‐catchment;
V. Improving the system to for predicting flooding extents and depths;
VI. Improving the capabilities at the flood forecasting center including human resources;
VII. Improving the system for public participation, public education and sensitization;
VIII. Improve on the application

BWB is estimated to service 66,822 individual connections, 813 water kiosks (for communal supply), and a fur-ther 3,000 commercial, industrial and institutional connections. The utility manages a reticulation system of about 1407km and 23 reservoirs (of which four clear water tanks) with an estimated capacity of 97,317m3. The management of the system is divided into three zones, Limbe, Kabula, and Soche.
The project will, (i) prioritize network upgrades to improve the hydraulic performance of the system, control pressures and leakages, (ii) improve storage capacity and reliability of supply by constructing new storage tanks and construction of solar Photo Voltaic (PV) plants stations (iii) expand the services to new unserved areas, us-ing the water recovered from leakage and the additional production capacity.
As part of this consultancy, BWB plans to carry out a hydraulic study on its reticulation system and is envisaging a three-stage approach to stabilize the network and improve efficiency in water supply. The first stage would fo-cus on priority network interventions to improve the hydraulic performance of the system, control pressures and leakages. A second stage would encompass a physical water loss reduction program through an internal per-formance-based mechanism. The third phase relates the network expansion to increase coverage. The network expansion will be undertaken through improvements in the efficiency of the existing system, savings from physi-cal water loss reduction activities, construction/upgrading of a treatment plant at Mudi or a combination of these three.

The following deliverables were finally agreed based on the ToR.
(i) preparation of detailed designs, drawings, and specifications for the priority network rehabilitation and upgrades (including storage reservoirs), which will be identified through the hydraulic study;
(ii) hydraulic analysis and preparation of detailed designs, drawings, and specifications for network ex-pansion investments;
(iii) preparation of detailed designs, drawings, and specifications for the construction of Solar PV plants in pumping stations;
(iv) preparation of tender document for both the priority network upgrades and network expansion works; and
(v) construction supervision of all network interventions.
(vi) Ensuring compliance with and Environmental and Social risk management requirements

In early March 2019, heavy rains and strong winds developed from a Tropical Depression and Tropical Cyclone Idai hit Malawi, causing severe flooding in the Southern and, to a lesser extent, Central Region of the country. The Government of Malawi has therefore received an Additional Financing which was therefore deemed as the most appropriate instrument to allocate addition-al IDA resources through the Crisis Response Window to scale up some of the parent project (MRDRMP) original components, thereby increasing the development impact of the project. The new project, Malawi Resilience and Disaster Risk Management Project aims to support the recovery of livelihoods and infrastructure in affected areas and strengthen capacity for flood and drought risk management.
This consultancy aimed to reduce the risk of communities exposed to flooding and enhance the resilience of community to drought through strategic infrastructure investments

The consultancy services targeted in seventeen (17) multipurpose water harvesting structures spread across ten districts within the project area, which in general is the Shire River Basin. Following the kickoff meeting, it was proposed by the Client a new list of sites to be considered, separating the list in two categories, as some of them are priority for the Ministry and designs have to be completed the soonest possible.

The water harvesting sites are classified into the following groups in terms of construction type:
‐ Group A: Consists of Mtonda, Zomba South, Namalowa, Phalombe Minor and Sombani. These sites were supplied with small gravity concrete dams.
‐ Group B: Consists of Chete, Dedza and Nsuwa, were supplied with earthen embankment dams.
‐ Group C: Kasangadzi and Nthondo / Kaueno are existing earthen embankment dams, proposed to be raised and maintained. Regarding Nantipwiri / Mbandanga, its design consists of the reconstruction of its severely damaged spillway.

The water harvesting sites of Zomba South, Phalombe, Nsuwa, Kasangadzi, Nthondo and Namalowa (replacement site) have been constructed and are now operating.

The provided services cover the fields of:
a) To prepare detailed technical environmental, social and economic feasibility study reports and preliminary designs for the targeted small and medium multipurpose dams and associated structures for flood control, irrigation and water supply to surrounding areas under the project;
b) To prepare environmental screening and social management and monitoring plans;
c) To prepare climate resilient detailed engineering designs, specifications, and confidential cost estimates for the tar-geted small and medium multipurpose dams and associated structures;
d) To prepare detailed bidding documents and construction implementation framework for the works;
e) To provide engineering supervision, contract management and quality service during the construction works;
