Delivering Indonesia’s Future Water Infrastructure
PT Indonesia Water Solutions provides advanced water, wastewater, and desalination solutions to support Indonesia’s growing industrial and environmental needs through strategic partnerships, innovative technologies, and sustainable infrastructure development.
CORE ISSUES
Indonesia's water sector faces three critical priorities: expanding wastewater infrastructure, improving industrial water management, and strengthening domestic resource security through sustainable salt production. Together, these initiatives support national development, environmental protection, and long-term water resilience.
-
Only 7% of Indonesia’s wastewater is treated, meaning the vast majority of domestic and mixed wastewater is discharged without adequate treatment into rivers, drains, and coastal waters—driving chronic water pollution, growing regulatory and reputational pressure on cities, industrial estates, and factories.
-
Indonesia’s mining, energy, petrochemical, and broader industrial clusters are creating urgent demand for advanced water infrastructure—ranging from industrial wastewater treatment and process-water recycling to seawater desalination and, where regulations or site constraints require it, zero liquid discharge (ZLD) solutions.
-
Indonesia produces roughly 2.2 million tonnes of domestic salt, with an average NaCl content of about 94% well short of total demand of around 5 million tonnes. As a result, the country relies on imports to cover more than half of its salt requirements.

NATIONAL PRIORITY
-
The government is targeting national self-sufficiency in salt production. Through the sovereign wealth fund, Danantara, we plan to add 340,000 tonnes per year of new domestic capacity, while the remaining shortfall will be addressed by private-sector investment supported through targeted incentives.
-
Indonesia is scaling up wastewater treatment under its Sanitasi Aman 2030 roadmap: from a 10.16% safely managed sanitation baseline in 2021, to 30% by 2030 by accelerating city-scale sewerage/WWTPs (SPALD-T) and strengthening on-site sanitation (SPALD-S) through scheduled desludging and upgraded septage treatment.
-
The government is accelerating industrial water infrastructure by pairing tighter compliance with investment incentives. It offers significant tax holidays and allowances for eligible investments. It is expanding SPARING (online effluent monitoring), pushing factories and industrial estates to upgrade WWTPs and adopt reuse/ZLD where needed.
VISION
We aim to be a long-term local platform for developing, financing, building, and operating water assets that meet international performance standards while remaining cost-effective in Indonesian operating conditions.
MISSIONPT Indonesia Water Solutions was established to address Indonesia’s critical water infrastructure gaps in, wastewater treatment, reliable clean water supply, and salt production from seawater desalination.
