@Vorastra Maybe of interest but this is the "southern system"

Northdene 1+2 supply mostly Malvern, Bellair etc and are downhill so both pump and gravity. Firwood is a two fold system: one receives water via pumps from Northdene and uses gravity distribution in the lower/middle hieght areas with the second being fed by a direct inlet that gets full via saturation of one. The second has booster pumps to move water to the higher elevations but those only kick in once the second has reached a mark of around 3m. So what happens often is that there is a knock on effect, especially loadshedding where there is not enough water saturation in one to help get the second to that 3m mark which means high elevations site with no water whereas someone literally 5 housed downhill may have but with low pressure.
