Checklist 3: Reservoir Design
1. Reservoir Configuration
☐ Two reservoir chambers available
The reservoir system must be designed with at least two chambers to allow flexible operation, maintenance, and cleaning without interrupting water supply.
2. Storage Time Control
☐ Retention time below 72 hours
Water retention time must be limited to avoid deterioration of water quality, including microbial growth, temperature effects, and loss of disinfectant residual.
3. Hydraulic Performance
☐ Proper hydraulic mixing ensured
Reservoirs must be designed to guarantee continuous water movement and prevent stagnation zones, short-circuiting, or dead zones within the storage system.
4. Access and Safety
☐ Secure access provided
Safe and controlled access must be ensured for operators, including protection against unauthorized entry and compliance with operational safety requirements.
5. Ventilation System
☐ Ventilation installed
Proper ventilation must be provided to maintain air exchange, prevent condensation, and support hygienic operating conditions inside the reservoir structure.
6. Cleanability
☐ Cleaning possible
The reservoir must be designed so that full cleaning and inspection can be carried out without structural limitations or long service interruptions.
7. Overflow Protection
☐ Overflow provided
An overflow system must be installed to prevent flooding, structural damage, and contamination risks during overfilling events or control failures.
8. Emergency Storage
☐ Emergency storage considered
Sufficient reserve volume must be included to ensure continued supply during peak demand, maintenance periods, or unexpected system disruptions.
