Calculation of Infrastructure Networks Project Name Location Project Categ. Owner Design by Date

This document calculates the infrastructure requirements for a project including water and firefighting networks. It estimates the population at 2840 people based on 568 apartments with 5 people per unit. It then calculates the daily water consumption needs and required water tank capacity. It also calculates the firefighting water requirements based on internal and external firefighting flows and tank sizing. Finally, it specifies the minimum residual pressure requirements for the water and firefighting networks.
