A B S T R A C T Indonesia is predicted to experience a deficit in groundwater availability in 2040, covering urban areas, including Serang City. The increasing urban population has become a new burden on the water supply, which has been relying on groundwater. Pandemic Covid-19 adds new challenges while simultaneously realizing the need for aspects of clean and healthy living behavior to minimize the potential for spreading the virus. Based on these conditions, it is necessary to conduct a study related to the projection of the need and availability of clean water in Serang City until 2031, as well as efforts to anticipate the fulfillment of clean water, and solutions to problems, especially in urban areas through sustainable development related to the need for clean water that is environmentally friendly and has a concept of environmental sustainability. Based on the analysis results, it is obtained that the projected clean water needs of Serang City for domestic and non-domestic clean water needs and the need for clean water that can be treated are insufficient. The clean water production capacity of PDAM Tirta Albantani and PDAB Tirta Madani, a supplier of clean water in Serang City, is not yet optimal, so it needs new technology; the concept of the City cares about clean water using nature-based technology. A B S T R A K Indonesia diprediksi pada tahun 2040 mengalami defisit ketersediaan air tanah meliputi wilayah urban termasuk Kota Serang. Bertambahnya jumlah penduduk urban menjadi beban baru dalam penyediaan air yang selama ini mengandalkan air tanah. Pandemic Covid-19 menambah tantangan baru sekaligus menyadarkan perlunya aspek perilaku hidup bersih dan sehat untuk meminimalkan potensi penyebarluasan virus tersebut. Berdasarkan kondisi tersebut perlu dilakukan kajian terkait proyeksi kebutuhan dan ketersediaan air bersih di Kota Serang hingga Tahun 2031 serta upaya antisipasi pemenuhan air bersih, solusi terhadap permasalahan terutama di wilayah perkotaan melalui pembangunan keberlanjutan terkait kebutuhan air bersih yang ramah lingkungan dan berkonsep pada kelestarian lingkungan Berdasarkan hasil analisis diperoleh proyeksi kebutuhan air bersih Kota Serang untuk kebutuhan air bersih domestik, non-domestik dan kebutuhan air bersih yang dapat diolah tidak mencukupi. Kapasitas produksi air bersih PDAM Tirta Albantani dan PDAB Tirta Madani sebagai pemasok air bersih di Kota Serang belum optimal sehingga perlu teknologi baru, konsep Kota peduli air bersih menggunakan teknologi berbasis alam.

Introduction The biggest challenge for developing countries is that it is projected that 50 percent of the population will live in urban areas by 2050, which has an impact on problems related to water security. The solution to these problems requires a multi-disciplinary approach that involves experts or researchers in the exact and social fields as well as stakeholders from various fields [1]. Five dimensions of urban water security in estimating water resources in Iraq for the period 2100 include accessibility, availability, clean water and sanitation, the economic value of water, and the environment. The projected future trend shows a decrease in the availability of clean water and an increase in variability due to climate change [2].
