Indonesia's PEJOMPONGAN 2 Project: A Pillar of Jakarta's Water Security

The PEJOMPONGAN 2 Water Purification Plant Expansion Project stands as a cornerstone of Indonesia's national strategy to address urban water scarcity and improve public health in Jakarta. As the capital's population grows and industrialization accelerates, the demand for reliable, high-quality drinking water has outpaced existing infrastructure capacity— making this $multi-million project a priority for the Indonesian government.

With a designed daily treatment capacity of 150,000 cubic meters, the plant will process raw water from regional sources into potable water meeting Indonesia's national drinking water standards (Peraturan Menteri Lingkungan Hidup No. 2 Tahun 2026) , directly benefiting over 500,000 residents across Jakarta and surrounding areas. Beyond expanding supply, the project emphasizes operational efficiency and environmental sustainability, aligning with Indonesia's commitments to UN Sustainable Development Goal 6 (clean water and sanitation).

The water purification process imposes stringent technical requirements on valve systems, driven by Jakarta's unique water characteristics and tropical operating conditions:

- Variable raw water quality: Raw water contains suspended solids, organic matter, and occasional sediment—demanding valves with anti-clogging designs and wear resistance;

- Tropical climate resilience: High humidity, temperature fluctuations (25–35℃), and salt mist exposure require corrosion-resistant materials and robust external protection;

- Strict hygiene standards: Valves must prevent cross-contamination and meet potable water contact material requirements (NSF/ANSI 61) to ensure water quality;

- Continuous operation demands: Municipal water treatment operates 24/7, requiring valves with high cycle life (≥30,000 operations) and low maintenance needs;

- Flow control precision: The plant's multi-stage treatment (coagulation, sedimentation, filtration, disinfection) requires precise flow regulation and reliable isolation to maintain process efficiency.

After rigorous technical evaluation and compliance verification, WEIZIDOM was selected as the core valve supplier for its ability to deliver application-specific products, compliance with Indonesian SNI standards, and proven expertise in tropical water infrastructure projects.
