    • Supercomputer-based precipitation forecasting system (PFS) and uses it to apply advanced water management.
    • Precipitation Prediction Model (K-PPM) has been constructed as a 3×3 km high resolution grid system to take account of the
    detailed geographical characteristics of dam and reservoir areas.
    • Provides data on precipitation forecasting for five days on an hourly basis (120 hours) four times a day.
    ⚫ ICT-based water operation systems to acquire, monitor and control all relevant data on a real-time basis from the whole
    water supply systems ranging from water sources to tap water
    ⚫ The acquired data are analyzed in terms of water quantity, water quality and energy management with the help of
    intelligent water network software that enable to supply drinking water without service interruption and formulate an
    optimal plan to rehabilitate water supply infrastructure.
    ⚫ water-Net: Diagnosis, Operation and Management System for Water Distribution Networks
    • A water network operation system with which it’s possible to collect real-time information about waterworks,
    ensure a GIS-based water network inspection, and manage water quantity, quality and crisis and energy.
    ⚫ LID element technologies
    • Bio retention: storm water pond, tree box filter, storm water wetland, Infiltration basin
    • Green roof, rain garden
    • Porous pavement, water-retentive pavement
    • Infiltration trench, Infiltration channel, Infiltration chamber

    Green Infrastructure !!
    Conventional Water Treatment Plant ❖ Decentralized water supply system, combined with
    auxiliary water sources and emergency water supply
    storage using storage tanks and deep tunnels,
    ensures a safe and stable water supply.

    ❖ Effects
    • Ensures customer-oriented safe and stable
    water supply in the future
    • Aims to make zero cutting-off water supply
    and increase a direct water supply rate from
    the current level of 5% to 30%
    • Energy saving from clean energy
    Key barriers Key enablers
    Factors limiting successful SWM implementation Factors for successful SWM implementation

    • Lack of initial support/investment • Political commitment at all levels


    • Access to skills/capacity to use SWM solutions • Policy, legislation and regulation support
    • Access to infrastructure or resources • Combining the use of SWM tools with other methods
    • Evolving technology/upgrades (high costs) • Strong stakeholder engagement from the beginning
    • Lack of compatibility across SWM solutions • Multidisciplinary approach
    • Hesitation to replace traditional infrastructure • Long-term investment for ongoing R&D
    • Lack of policy incentives • Capacity development, training and
    education
