Anpassung an den Klimawandel in Adscharien -Küstenschutz- Regenwasserbewirtschaftungssystem Batumi, Phase 2 Climate Change Adaptation Programme in Ajara -Batumi Stormwater II Das Programm Batumi III umfasst die Rehabilitierung und den teilweisen Neubau der Wasser-versorgungs- und Abwasserentsorgungseinrichtungen der Stadt Batumi in drei aufeinander auf-bauenden Programmphasen. Ziel ist rund 208.000 Einwohner kontinuierlich und bedarfsgerecht mit hygienisch unbedenklichem Trinkwasser zu versorgen. Das Abwasser und Niederschlagswasser soll durch die Sanierung und Erweiterung der Trennkanalisation sowie durch den Neubau einer Abwasserreinigungsanlage umweltgerecht abgeleitet und gereinigt werden. Damit wird ein Beitrag zur nachhaltigen und umweltgerechten Kommunalentwicklung sowie zur Verbesserung der Siedlungshygiene und der Lebensbedingungen der Bevölkerung sowie der Stadt Batumi geleistet. Zielgruppe sind die Einwohner der Stadt Batumi, ursprünglich in der alten Verwaltungs-grenze, die aber während der Projektumsetzung um die Chakvi Dörfer und die südlichen Dörfer erweitert wurde. Projektträger ist die Stadtverwaltung von Batumi. Der Betrieb der Anlagen er-folgt durch das städtische Versorgungsunternehmen Batumi Tskali (BTS).Im Rahmen der Komponente Regenwasserbewirtschaftung wird die dritte Phase des Programms in zwei Ausbaustufen durch Maßnahmen für eine angemessene Regenwasserableitung ergänzt. Dies ist von hoher Relevanz, da das Stadtgebiet von Batumi aufgrund der besonderen geographischen Lage am Schwarzen Meer häufig von Überflutungen betroffen ist. Auf Grund von weiteren Bautätigkeiten in der schnell wachsenden Stadt und der damit einhergehenden Versiegelung von Flächen ist eine umfassende Gesamtplanung und eine enge Verknüpfung mit den laufenden FZ-Maßnahmen erforderlich. Mit Investitionen in die Regenwasserkanalisation und die Errichtung eines Regenwasserspeicherbecken mit Pumpstation und Meerauslass soll die Überflutungshäufigkeit des Stadtgebietes bei Starkregenereignissen weiter reduziert und eine verbesserte Wasserqualität am Badestrand erzielt werden. Das FZ Finanzierungsvolumen beträgt rund EUR 14 Mio. (FZ Darlehen rd. EUR 7 Mio. und FZ Zuschuss EUR 7 Mio.) und wird durch weitere lokal finanzierte Baumaßnahmen der Regenwasserkanalisation ergänzt. The programme Batumi III comprises the rehabilitation and partial new construction of the water supply and wastewater disposal facilities of the city of Batumi in three successive program phases. The aim is to supply around 208,000 inhabitants continuously with hygienically safe drinking water in line with their needs. Wastewater and stormwater are to be diverted and treated in an environmentally sound manner through the rehabilitation and expansion of the separate sewer system and the construction of a new wastewater treatment plant. This will contribute to sustainable and environmentally sound municipal development as well as to the improvement of sanitation and living conditions of the population and the city of Batumi. The target group are the inhabitants of the city of Batumi, originally in the old administrative boundary, but extended during the project implementation to include the Chakvi villages and the southern villages. The project executing agency is the Municipality of Batumi. The operation of the facilities is carried out by the municipal utility Batumi Tskali (BTS).Under the stormwater management component, the third phase of the program will be supplemented in two expansion stages by measures for adequate stormwater drainage. This is highly relevant, as the urban area of Batumi is frequently affected by flooding due to its special geographical location on the Black Sea. Due to further construction activities in the rapidly growing city and the resulting sealing of areas, comprehensive overall planning and a close link with the ongoing FC measures are required. Investments in the stormwater drainage system and the construction of a stormwater storage basin with pumping station and sea outfall are intended to further reduce the flooding frequency of the urban area during heavy rain events and to achieve improved water quality at the bathing beach. The FC financing volume amounts to around EUR 14 million (FC loan approx. EUR 7 million and FC grant EUR 7 million) and will be supplemented by further locally financed construction measures of the storm water drainage system.
