RFP
The project's objective was tthe identification of a Multipurpose Water Resources Management and Development project to improve water, food and energy security, to reduce flow variability and flood damage and to contribute towards improved livelihoods without compromising the environment. The main study outputs were an identification study report upon which detailed preparation and investment would be based. The specific objectives of the assignment were: a) to identify potential regional investment options, taking into account their economic, social and environmental implications as well as cumulative impacts, b) to investigate the alignment of potential regional investment options with national level priorities and plans, c) to prioritize and sequence potential investments, also in light of existing and planned interventions up to 2035 and d) to prepare an investment project that falls within the National Planning Frameworks of Uganda and Southern Sudan. In order to achieve these objectives the Consultant delivered a Situational Analysis Report, a Multipurpose Basin Water Resources Development and Management Strategy Plan, an Investment Plan and, finally a report identifying a Bankable Investment Project among the initially evaluated alternatives.
CONSULTANCY SERVICES FOR NRW REDUCTION, HYDRAULIC MODELLING AND GIS DEVELOPMENT

RFP
The scope of this project was the development of a coherent framework of principles and practices, established in international practice, for reducing AAWSA overall Non Revenue Water (NRW) from a current level of about 36% to 40% to a level of 20% by the year 2020. Addis Ababa and its surrounding areas had population estimated to about 3.5 million inhabitants. A significant aspect of this project within the overall scope was also the Capacity Building of AAWSA personnel. In this sense, the project also aimed to provide to all AAWSA organizational levels (NRW Task Force, Development, GIS, Operation and Maintenance and Accounting Departments) the means and the ability to continuously evaluate and implement future schemes of cost effective NRW management.Ten pilot District Metered Areas each including approximately 800-1200 customers were proposed. Zero pressure tests were performed to test DMA watertightness and the Active Leakage Control was carried out using listening sticks, leak noise correlators and ground microphones. DMA Minimum Night Flow analysis was carried out using available field data. A program of individual consumer demand monitoring of sampled customers was implemented for use in the Minimum Night Flow Analysis.

The first phase included the preparation of preliminary studies for civil and electromechanological works and the second phase (after the Client's approval) contained the preparation of the detailed design study of the total project. The project was tendered.
CONSULTANCY SERVICES FOR DAMS SAFETY INSPECTION IN HYDROPOWER STATIONS IN KENYA
Country: KENYA , Year: 2011 - 2012 , Client: Kenya Electricity Generating Comp. Ltd , Funding: Kenya Electricity Generating Comp. Ltd , Contract Value: 168,540.00 € (222,472.80 USD) , Tags: Dams & Hydropower
RFP
The services provided by the Consultant focused on the assessment of dam safety for the following hydroprojects, owned by the Kenya Generating Company in: (a) Upper Tana basin, (b) Lower Tana basin and (c) some isolated stations. The safety assessments concerned dam safety, that is the safety of the water retaining structures themselves, as well as any appurtenant structures related to the safety of the dams themselves, such as spillways, bottom outlets, etc. Dams and their appurtenant structures were inspected by highly experienced engineers, based on detailed checklists for (a) the crest area, (b) the downstream slope, (c) the upstream slope, (d) the installed instrumentation, (e) the downstream area, (f) the spillway and (g) the galleries [for seepage, inspection, access, etc] and bottom outlet chambers of each dam. Training workshops were organized in Nairobi including presentation and training on key issues related to dam safety and, finally, presentation of the particular characteristics, safety issues and monitoring demands of the Ken Gen dams.
TECHNICAL EVALUATION OF THE SMALL HYDROELECTRIC POWER PLANT “ARGIRI” WITH CAPACITY OF 6,35 MW IN ARGITHEA MUNICIPALITY, CENTRAL GREECE
Country: GREECE , Year: 2011 - 2012 , Client: PROTERGIA S.A. , Funding: Private Investment Fund , Contract Value: 19,680.00€ (26,684 US$) , Tags: Dams & Hydropower
RFP
The project involved the technical evaluation of the design and operation of the small hydropower plant “Argyri”. The evaluation included a review of the hydrology of the basin, the review of the geological and geotechnical parameters of the project, the review of the hydraulic design of the intake facilities and the evaluation of the installed electro-mechanical equipment, including gates, control boards, the turbine and generator complex and the associated facilities.
It was found that the plant was generally well designed and built, apart from several intake design inefficiencies which caused unnecessary delays and stop-downs, especially during times of crucial peak load operations.
The study resulted in a number of proposals to improve the plant operation, mainly through structural improvements of the intake works.
