Project Overview

The Net-Zero Water Supply Infrastructure Project is a flagship initiative aimed at delivering sustainable and innovative water solutions to Nusantara, Indonesia's new capital city. The project supports a planned population of approximately 118,125 people, with a Phase 1 capacity of 350 liters per second (lps), ensuring clean, reliable, and safe water access.

This ambitious project focuses on constructing a Water Treatment Plant (WTP) optimized for local raw water conditions. The WTP incorporates advanced treatment processes and operation management plans to minimize energy consumption and align with the eco-friendly goals of Nusantara. Solar panels and other renewable energy sources are being integrated to achieve a carbon-neutral operation.

Spanning over a meticulously planned layout, the project features cutting-edge piping systems and ensures slope stability for all critical infrastructure. Extensive safety analyses confirm the stability of slopes, meeting or exceeding standard safety factors.

K-water’s expertise in design, construction, and operation management has been instrumental in addressing key challenges. The project embodies K-water’s commitment to innovation, sustainability, and partnership, establishing a model for future water infrastructure projects in rapidly developing regions.

Project Overview

The Smart Water Management Pilot Project in Denpasar is a collaboration between South Korea and Indonesia to improve urban water management using digital technologies. As Bali’s capital, Denpasar faces challenges in water supply due to urbanization and climate change. This project aims to enhance water distribution efficiency and ensure a reliable supply by integrating smart monitoring and management solutions.

Key features include real-time pipe water monitoring, leak detection, and IoT-based smart meters. These technologies will help optimize water distribution, reduce non-revenue water (NRW) losses, and improve overall system efficiency. Additionally, data-driven insights will support better decision-making for future water management strategies.

This pilot project is expected to set a benchmark for smart water management in Indonesia. Its success in Denpasar could lead to broader implementation in other cities, supporting national water security and sustainable urban development while strengthening cooperation between Indonesia and South Korea.
