This paper presents and discusses the keys of success of a water reuse project for landscape irrigation and other urban uses in Bora Bora, French Polynesia. To better preserve public health and overcome all constraints and public opposition, a membrane tertiary treatment for the production of high-quality recycled water was implemented. Special attention was paid to the reliability of operation and economic viability of membrane treatment, as well as to active public participation with involvement of all stakeholders. The demand for the new recycled water steadily increased during the last two years with a wide diversification of urban uses, not only for irrigation, but also for cleaning, industrial and commercial uses and fire protection. Monetary and non-monetary benefits have been assessed and recognised. As a result of this successful project, new recycling projects are under development.

With the acceleration of global sustainable development, the shortage of water resources especially the city has become the focus of attention in all countries since water is the key to build a resources-saving ecological city. The article improved the existing "rain garden" project and replenished the purification of the rain in order to realize the urban water cyclic utilization ,through recycling rainwater, which can manage rainstorm effectively , improve the urban water cycle system, as well as supply urban irrigation and underground water. Besides, the combination of urban landscape and stormwater management system, if widely accepted, will not only improve the urban water problem, but also improve the urban environment, alleviating the urban heat island effect and improving the local climate. It can shape a new resources-saving ecological city and then realize the sustainable development of resources.

The Social

Rural areas cover the largest part of the territory of Lithuania as well as that of the whole Europe. Rural settlements are also the most abundant category in the settlement system of the country. Therefore, their social, economic, and cultural viability- as well as ecologic sustainability playan important role striving towards the goals of sustainable development. During the last years projects promoting various aspects of sustainability are implemented not only in large cities and towns, but also in smaller municipalities, nevertheless many rural settlements still are not influenced by these trends. The tendency of decrease of the population of the country, emigration, migration of young and qualified persons to larger cities and towns, poverty and unemployment cause the threat to the most fragile elements of the rural settlement system, such as steadings, manor residencies and ethnographic village settlements. In order to stop these processes it is necessary to search for means to sustain the social and economic viability of rural settlements. During the last decade significant role of cultural heritage in implementing strategies of sustainable development was universally recognized. It is acknowledged that sustainable preservation, maintenance, and use of cultural heritage, especially immovable, positively influence the social, economic, cultural and even environmental dimensions of sustainable development. Sustainable development opportunities provided by immovable cultural heritage are essential for small rural settlements which are not distinguished by important natural resources or favorable location. In this instance social and cultural viability is as much essential for preservation of immovable cultural heritage of these settlements, as immovable cultural heritage is essential for sustention of their social and economic viability. Nekilnojamojo kultūros paveldo įtaka darniam kaimo gyvenamųjų vietovių vystymuisi Santrauka Didžiąją Lietuvos, kaip ir visos Europos, teritorijos dalį sudaro kaimo vietovės, o didžiąją dalį gyvenamųjų vietovių – kaimo gyvenamosios vietovės, taigi jų socialinis, eko nominis ir kultūrinis gyvybingumas bei eko loginis tvarumas atlieka lemiamą vaidmenį siekiant šalies darnaus vystymosi tikslų. Pastaraisiais metais darnų vystymąsi skatinantys projektai jau įgyvendinami ne tik didžiuosiuose Lietuvos miestuose, bet ir mažesnėse savivaldybėse, tačiau daugelio kaimo gyvenamųjų vietovių šis procesas kol kas nepaliečia. Bendro šalies gyventojų skaičiaus mažėjimo tendencija, emigracija, jaunų ir kvalifikuo tų žmonių migracija į didžiuosius šalies miestus, skurdas ir nedarbo grėsmė kelia sunykimo grėsmę patiems jautriausiems ir kultūriniu požiūriu vertingiausiems šalies kaimo gyvenamųjų vietovių sistemos elementams, tokiems kaip vienkieminės sodybos, buvusių dvarų ir palivarkų sodybos ar etnografinės kaimų gyvenvietės. Siekiant sustabdyti šiuos neigiamus socialinius, eko nominius bei kultūriniu procesus, būtina ieškoti būdų, kaip užtikrinti kaimo gyvenamųjų vietovių socialinį bei eko nominį gyvybingumą. Pastaraisiais metais pasaulyje vis aiškiau suvokiamas kultūros paveldo vaidmuo darnaus vystymosi kontekste. Visuotinai pripažįstama, jog kultūros paveldo, ypač nekilnojamojo, apsauga, priežiūra bei naudojimas turi teigiamos įtakos darniam vystymuisi socialinėje, eko nominėje, kultūrinėje ir kt. dimensijose. Nekilnojamojo kultūros paveldo teikiamos darnaus vystymosi galimybės itin reikšmingos nedidelėms, išskirtinių gamtinių išteklių neturinčioms bei patogia geografine padėtimi nepasižyminčioms kaimo gyvenamosioms vietovėms. Jų socialinis ir eko nominis gyvybingumas kultūros paveldui išsaugoti yra toks pats svarbus, kaip ir kultūros paveldas socialinio ir eko nominio šių gyvenamųjų vietovių gyvybingumo palaikymu.

Sustainable Urban Water Management

Decentralized wastewater treatment has the potential to provide sanitation that meets criteria for sustainable urban water management in a manner that is less resource intensive and more cost effective than centralized approaches. It can facilitate water reuse and nutrient recovery and can potentially reduce the ecological risks of wastewater system failure and the community health risk in a wastewater reuse scheme. This paper examines the potential role of membrane technology in sustainable decentralized sanitation. It is argued that the combination of membrane technology within decentralized systems can satisfy many of the criteria for sustainable urban water management. In particular, the role of membranes as a dependable barrier in the wastewater treatment process can increase system reliability as well as lowering the latent risks due to wastewater reuse. The modular nature of membranes will allow plant size to range from single dwellings, through clusters to suburb size. It is concluded that realization of the potential for membrane-based technologies in decentralized wastewater treatment will require some progress both technically and institutionally. The areas where advances are necessary are outlined.
