Rapid urban­iza­tion has led to an increase in urban slums, which are dense­ly pop­u­lat­ed but lack basic ser­vices such as clean water and san­i­ta­tion. Slums, often locat­ed along rivers, are vul­ner­a­ble to dis­as­ters such as floods and land­slides, which have a sig­nif­i­cant impact on their well-being. How­ev­er, these issues are often over­looked in nation­al and local plan­ning. The cities of Man­a­do, Pon­tianak, and Bima face sim­i­lar issues relat­ed to flood risk, socio-eco­nom­ic con­di­tions, and urban­iza­tion, with clean water infra­struc­ture that does not opti­mal­ly serve the com­mu­ni­ty, espe­cial­ly in slums.

To main­tain the avail­abil­i­ty of clean water, sus­tain­able water man­age­ment with eco­hy­drol­o­gy prin­ci­ples is need­ed, such as rain­wa­ter har­vest­ing facil­i­ties and rain­wa­ter con­ver­sion sys­tems into clean water. Con­trol­ling urban­iza­tion should be done with reg­u­la­tions and law enforce­ment, as well as fur­ther stud­ies on water sup­ply and san­i­ta­tion tar­iffs and res­i­dents’ will­ing­ness to pay for them. High tech­nol­o­gy, such as dig­i­tal water man­age­ment, can be opti­mized for water sup­ply at var­i­ous scales.

This book aims to pro­file water sup­ply in slum neigh­bor­hoods in the three cities. It is expect­ed to con­tribute to inclu­sive and par­tic­i­pa­to­ry urban plan­ning to improve the qual­i­ty of pub­lic spaces and urban envi­ron­ments in slums.
