Located at the Western of Shiga Prefecture (Japan), Harie district has been known for its urban ecology model aligned with freshwater canals. Indeed, thanks to intersection between Adogawa River and Biwa Lake, which is the biggest freshwater lake in Japan, in Harie, houses are connected to water supply system pump water from underground water abundance. With the “kabata”, which function is likely a water room or a kitchen used to store and prepare foods, being linked to outdoor freshwater canals, households have used the “kabata” to keep water pumped directly from the underground, and have utilized it for cooking and drinking. Unlike ordinary water faucets, which are opened to use and locked when not being used, faucets at “kabata” have flown constantly, no need to be locked, constant water flow to wash away residue from foods and utensils. As water has temperature around 13 degree Celsius, residents have used “kabata” for cooling fruits, veggies, and beverages. Freshwater springs flow around houses all years that created an unique feature of Harie district’s urban scenery and culture.

Through generations, residents at Harie district have lived in harmony with the aforementioned ecosystem. In the “kabata”, the residents released carp to cleanse the water. Indeed, when leaving veggies, fruits in the “kabata”, constant water wipes away dirt, and residues are food for carp residents. Those carps have been considered as families’ pets playing a crucial role, which is to help families cleanse up residues from foods and purify water run into the “kabata” in particular and in the canals system of Harie district in general.
The “Kabata” has been attached with water culture of Harie district. In New Year, annually, residents take water from the “kabata” for their ancestor worship and foods preparation for New Year celebration. With a consciousness and care on importance of the “kabata” to their life, residents at Harie have been careful in water conservation.

The project has consisted of: i) develop systems and plans for waste water treatment units on Cat Ba island; ii) develop operation procedure and management of waste water units on Cat Ba island; iii) implement monitoring coastal water sources around Cat Ba archipelago; iv) implement green activities; v) environment protection activities through cooperation enhancement between Hai Phong city and Quang Ninh province./.
