Firewater Hydraulics and Water Supply Design
Proving the system can deliver the flow and pressure the scenario demands
Firewater systems are frequently designed for a demand that was never recalculated after the plant grew. This course covers demand determination, hydraulic network analysis, pump selection and testing, and the storage duration that the design scenario actually requires.
This course sits alongside our Firewater Hydraulic Analysis consulting work, so what is taught is what we do.
Who should attend
Course content
Every module is taught with worked examples and exercises drawn from real plant, and adapted to your own process where the course runs in house.
Demand determination
- Design fire scenario selection and the largest single risk area
- Fixed system demand, hydrant and monitor demand and hose stream allowance
- Simultaneous demand and the case that governs
- Cooling water for exposure protection
Network hydraulics
- Loop against dead end configuration and sectional isolation
- Friction loss calculation and the Hazen Williams basis
- Residual pressure at the hydraulically remote point
- Modelling the network and validating against flow test data
Pumps and supply
- Pump selection, driver choice and redundancy
- Suction arrangements and net positive suction head
- Storage capacity and duration for the design scenario
- Jockey pumps and pressure maintenance
Testing and assurance
- Acceptance testing and the pump performance curve
- Periodic flow testing and churn testing
- Degradation causes including tuberculation and valve position
- Documenting capability against the design demand
What you receive
- A firewater demand calculation worksheet
- A hydraulic analysis worked example
- A pump and system test record template
- Assessment result and attendance record
What changes afterwards
- Demand is recalculated against the plant as it now stands
- Networks are verified at the hydraulically remote point
- Storage duration matches the scenario rather than a convention
- Testing proves capability instead of confirming the pump starts
Standards and references
We teach Firewater Hydraulics and Water Supply Design against NFPA 20 stationary fire pumps and NFPA 22 water tanks and the codes listed with it, at the edition current when you run it.
