IWWEF Overview

Indonesia Water and Wastewater Expo & Forum (IWWEF) is Indonesia’s premier biennial event dedicated to the water and wastewater sector. Fully hosted by PERPAMSI (Indonesia Water Supply Association), this national-scale event serves as a key gathering point for stakeholders in the water industry — from policymakers, regional water utilities (PDAM), government institutions, to private companies, investors, and technology providers.

Started as Nusantara Water in 2004, IWWEF was officially established in 2011 at Hotel Bidakara, and inaugurated by Deputy Minister of Public Works, Hermanto Dardak. 

It continued through significant years:
in 2013 by Vice President Boediono,
in 2015 by Minister of Public Works and Housing, Basuki Hadimuljono,
and in 2016 by Vice President of Republic of Indonesia Jusuf Kalla.
IWWEF has also traveled—held in Makassar in 2017,
then returned to Jakarta in 2019 and 2023 opened by Vice President KH Ma’ruf Amin.

IWWEF 2025 will feature a dynamic exhibition, international conference, and business matching forum, aiming to promote innovation, facilitate collaboration, and address critical challenges in water and wastewater management. The event provides a platform for companies to showcase solutions, share real-world experience, and exchange knowledge with peers across sectors.

Whether you're introducing the latest in smart water monitoring, advanced treatment technologies, or sustainable infrastructure, IWWEF offers unmatched visibility and access to targeted stakeholders.
