Abstract

An annual increase of urban communities has nowadays surpassed rural communities. As growing urban communities seek to minimise their impact of future challenge especially on already stressed water resources, an emerging challenge is to develop robust city infrastructure and its resilient communities so that can adapt to the future uncertainties affected by population, climate and societal change. Surabaya, as other majority of large cities in Indonesia has faced these typical issues. The water resilient city concept is designed to integrate water-related services, such as water resources and supply, municipal wastewater (greywater) reuse, sewerage and flood protection as well as green and liveable urban environments. Since municipal wastewater management relies on communal wastewater treatment plant targeting only blackwater treatment processes, an opportunity to treat greywater and conserve it as one of water resources has become an emerging concern. Therefore, in order to implement the concept of urban water management, innovative technological approaches are required to ensure secure water supplies and protect water environments. One of the innovative technological approaches is to design a pitcher irrigation concept system to improve municipal wastewater and stormwater quality through biologically (plant and attached microorganisms) media. As another advantage, treated greywater has a good potential to be used as a source of water for the community. The community can use the treated greywater for their daily use such as watering their plants or urban farming. Nevertheless, treatment performance and long-term sustainability are key indicators for evaluation before its implementation. These will be addressed in this current research.
