PERENCANAAN JARINGAN AIR BERSIH DAN DRAINASE AIR KOTOR DI PERUMAHAN PERMATA ANDALUSIA KECAMATAN DAU KABUPATEN MALANG JAWA TIMUR

The planning of clean water supply systems and wastewater drainage networks plays a crucial role in ensuring environmental sustainability and residential comfort in housing areas. This study aims to design an effective and efficient clean water distribution network and wastewater drainage system for the Permata Andalusia Housing Complex, located in Dau District, Malang Regency, East Java. The methodology includes collecting both primary and secondary data, analyzing clean water demand based on the projected population, and designing pipe distribution and drainage systems according to land topography, storage capacity, and Indonesian National Standards (SNI). The clean water system is designed as a gravity-fed closed network using PVC main pipelines and a central water reservoir. Meanwhile, the wastewater drainage system is planned as a closed-channel system leading to a domestic wastewater treatment facility. The result of this planning is expected to serve as a reference for infrastructure development, particularly in the provision of sanitation and basic utility services, to improve the quality of life for future residents of the housing complex.
