The following are case studies on field experiences and practical strategies for raw and purified water storage:
### 1. **Case Study: Improving Resilience of Urban Water Systems in the Face of Climate Change (UNESCO, 2021)**
**Elevated Storage Tanks** 🏗️
- **Application**: Coastal cities prone to storm surges.
- **Design**: Storage tanks elevated on towers or platforms.
- **Benefit**: Ensures continuous water supply and maintains pressure during floods, preventing contamination from floodwaters.
**Emergency Bypass Channels** 💧
- **Application**: Cities with frequent heavy rainfall.
- **Design**: Parallel channels to divert excess water away from treatment facilities.
- **Benefit**: Protects the main treatment plant and raw water storage from flooding, ensuring operations continue uninterrupted.
**Flexible Design** 🔄
- **Application**: Urban areas with variable flood risks.
- **Design**: Modular storage facilities that can be expanded or upgraded.
- **Benefit**: Adapts to changing climate conditions and increasing water demand.
### 2. **Flood-Resilient Water Supply and Sanitation Services: Practical Experiences from the Field (International Water Association, 2022)**
**Bangladesh** 🏞️
- **Application**: Low-lying, flood-prone areas.
- **Design**: Water storage tanks and treatment facilities raised on stilts.
- **Benefit**: Prevents floodwaters from contaminating water supplies, ensuring continuous access to clean water.
**Netherlands** 🌊
- **Application**: Regions below sea level with complex water management needs.
- **Design**: Dual-purpose reservoirs for raw water storage and flood control.
- **Benefit**: Manages both water supply and flood risks efficiently, using overflow mechanisms to handle excess water.
**Vietnam** 🚤
- **Application**: Mekong Delta region with seasonal flooding.
- **Design**: Floating treatment units and storage tanks.
- **Benefit**: Operates effectively even during high water levels, ensuring continuous water treatment and supply.
### 3. **Water Utility Case Studies in Flood Resilience (World Bank, 2021)**
**New Orleans, USA** 🌀
- **Application**: Post-Hurricane Katrina recovery.
- **Design**: Elevated and fortified storage facilities, comprehensive flood management with levees and pump stations.
- **Benefit**: Protects against future floods and maintains water supply during extreme weather events.
