The economic and humanitarian crisis in 2008 that included widespread cholera outbreaks prompted the Zimbabwean Government and the donors to begin dialogue on the modalities of financing relief and remedial efforts. The African Development Bank was asked by a group of donors, with the consent of the Zimbabwean Government, to establish and administer a ‘basket’ fund – the Zimbabwe Multi-Donor Trust Fund (the “Zim-Fund”). The main purpose for the Zim-Fund is to mobilise and administer donor resources needed for the economic recovery and development efforts in Zimbabwe. Part of the resources mobilised by the Zim-Fund have been applied towards the Urgent Water Supply and Sanitation Rehabilitation Project (UWSSRP) whose main scope is the urgent rehabilitation of water supply and sanitation systems in six urban centres, namely Harare, Chitungwiza, Mutare, Masvingo, Kwekwe and Chegutu with a combined population of approximately 4.15 million. Under the UWSSRP, the Zim-Fund also finances consultancy services for the development of Medium to Long Term Water Supply and Sanitation Investment Plans. The Investment Plans are intended to provide useful guides to the Municipalities and the Zim-Fund on the financing requirements and the phasing of future water supply and sanitation investments in the target towns.

Extension of Water Supply and Sewerage Network and Construction of a new Wastewater Treatment Plant in Sivas — Türkey
The water distribution network of the Turkish Provincial Capital Sivas showed urgent needs for rehabilitation and extension. Frequent flooding of the streets occurred due to missing separation between waste and stormwater parts of the existing sewage and stormwater system. Generated wastewater was discharged to the receiving river without any treatment. The Municipality of Sivas decided to launch an ambitious infrastructure investment program aiming at ensuring sustainable drinking water supply and sewage disposal.
For fulfillment of the project objectives a number of performance indicators was defined comprising legal stipulations concerning urban wastewater treatment or application of typical indicators such as connection rate, cost coverage, etc. which have been typically benchmarked by evaluation of comparable water utilities.
The investment program under the Sivas WSS project comprised the following measures (lots):
- Lot 1: Water supply improvement measures
- Lot 2: Rehabilitation of sewerage and stormwater drainage systems
- Lot 3: Construction of the main wastewater conveyor and a new WWTP (405,000 P.E.)
The Überseestadt is currently the biggest urban development area in Bremen – from the seaport to the new residential area and service district at the Weser. The goal was to provide a high quality public transport connection, taking into consideration the economic viability of the project. Therefore, the possibility of implementing trolley bus operation at the bus line 20 was analyzed.
In order to provide a high-quality and emission-free solution, the possibility of converting the bus line 20 into an electrically operated line was analyzed including transport and economic aspects in order to verify the technical feasibility of the transition.
However, the conversion from diesel based operation into a completely electrical solution requires bigger investment in infrastructure and in vehicles. In order to avoid high costs for the adaption of the infrastructure in the fields of road underpasses and intersections, also a hybrid alternative – “trolley bus+” – with efficient batteries for bridging the section without catenary, so that a completely electrical operation without the use of diesel engines would be possible was analyzed.
The study came to the result, that with a partly electrical solution (“trolley bus+” with efficient batteries) the investment costs could be reduced by 25%. Cost-effective operation under the current cost structures would be possible if the buses departed at least in 15 minutes intervals considering increasing urbanization.
Phase 1: Erection of Line U3, approx. 5.7 km, 9 stations, in operation since June 2008. Phase 2: Migration of Line U2 to automatic operation, approx. 13 km (already existing in conventional operation). Migration to unattended automatic train operation (UTO) until end of 2009.

Project’s goal was to clarify the requirements and prepare the technical specifications for the purchase of an automatic guidance and signalling system for the Helsinki Metro, in the process of introducing automatic unattended train operation UTO. The cooperation with system experts Prof. Schütte and Mr. Schmidt (project leader at Nuremberg metro automation project) ensured state-of-the-art system design.
Important technical conditions and overall requirements were defined in workshops, together with the client. On this basis, technical specifications for the system elements were prepared. Revision of generated specification documents and further coordination were carried out in further workshops. In order to avoid reiterations or contradictions, the elaborated specifications were reviewed internally upon final publication.
A conventional metro system was converted into an automatically operated for the very first time, while using existing vehicles.
Services included: Workshops for the clarification of technical conditions and requirements of the client and preparation of specifications and review of descriptions for implementation strategy, operational specifications, RAMS, technical requirements for control center, interlockings and wayside equipment, functional requirements for ATC and ATS, trial runs and acceptance.

In order to improve the parking area situation at rest stops and service stations, and off-motorway service areas, pre-gate parkingor slot-management improvement for trucks was developed using telematics-controlled truck parking (truck parking in columns). By the computerized-controlled arranging of the trucks according to their departure times, the existing area was optimally used with the result that 70 – 100 % more parking space was achieved. The fully automatic operation of the system was successfully tested and approved at the Montabaur service station and rest stop by the Frauenhofer Institute in summer 2013.
In the context of the complete renewal of the station road, the complete road environment has to be modified according to an urban development draft. First, the underground infrastructure including the house connections has to be renewed and expanded under operation. The infrastructure also includes a new drainage for infiltration water, installed with off-set heights and running parallel to the existing combined drainage, as well as a new pipeline for drinking water and telecommunication. The complete infrastructure and transport equipment measures have to be planned taking into consideration the private and commercial concerns of the neighbors and residents and should be accomplished section by section so that the access for residents can be guaranteed at all times. The necessary water rights authorizations and requirements of the traffic law have to be processed.
