Figure 5 (Marae 3): Three months of occupancy (day only and day and overnight) and total site water usage data - Data shows relatively infrequent marae usage with one major event recorded. There is a good correlation between site water usage and recorded occupancy with peak occupancy of 150 people coinciding with peak daily water usage of 4, 400 litres. Data also suggests very little water leakage from the site water reticulation system.
