Frequently Asked Questions
What is the formula for average water demand?
Average daily demand equals liters per capita per day, times the population, plus a 10 percent allowance for system losses and waste.
What is the water demand for a population of 10,000 at 225 liters per person per day?
That population has an average daily demand of about 2,475 cubic meters, a maximum daily demand of about 3,465 cubic meters, and a peak demand of about 5,693 cubic meters.
Why do water systems plan for peak demand, not just average?
Water infrastructure must be sized to handle short bursts of unusually high use, like a hot summer morning, without running short, so engineers design around peak, not average, demand.
