Water capacity

As a note is there any calculation differentiating the water capacity per suburban unit compared to apartment unit. I would think that a house would use substantially more water since the people can irrigate their lawn, well as wash their vechicles, or fill pools etc.

The work last year was continous geotech sampling (typically sonic drilling), which gives a continous representation of the soil stratigraphy which isn't possible when one uses SPT sampling methods (non continuous). SPT is the standard method of sampling in the geotech world, it generally is 1 sample every 2.5 feet to 10 feet, then every 5 feet after (with exceptions depending on what you're doing), it works by using a hollow metal tube (split spoon) which gets hammered into the ground using a 140lb automatic hammer to collect the sample, the number of times the hammer impacts can be correlated to the soils density, however the soil boundaries are interpreted because it is discontinuous. Sonic drilling is a hollow tube that gets vibrated into the ground to collect the soil core.

This years work is installing test wells to understand more of the hydrology of that area (permeability tests,  pumping tests). It's related to capacity but it isn't related to imminent capacity improvements.

Generally water capacity is calculated using PPU (people per unit), SFHs naturally have higher values then apartments just because of the different demographics typical of those housing types.

Awesome explanation, Thank you.
