The Vorna Valley & Waterfall Heights Hydraulic Gradient

See why two complexes 1.2km apart in Vorna Valley experience completely different water realities during bulk throttling.

Reservoir Base & Tower (1,599m - 1,629m) Hydraulic Grade Line (HGL) Your Address / Ridge: Waterfall Heights (1,535m) [DRY] Local Valley Sump: Jukskei Basin (1,480m) [POOLS]
01

Gravity Drain Sump

Water follows hydrostatic gravity. When bulk pressure drops, pipes at 1,480m stay pressurized from water pooling in the lowest invert of the main.

02

The Ridge Starvation Point

Waterfall Heights sits on the 1,535m ridge crest. When the reservoir drops below 25%, static head collapses below the ridge level, draining taps instantly.

03

The +18h Repressurization Lag

When valves reopen, lower-lying households consume inflow immediately, while air pockets pocket along ridge crests, delaying ridge pressure by 12ā€“24 hours.

"Why Does My Neighbour Down the Road Have Water?"

Compare Waterfall Heights (Bekker Rd Ridge) vs Lower Vorna Valley (Anton Hartman Basin)

HIGH-LYING RIDGE

Waterfall Heights (Bekker Rd)

1,535 m AMSL
Feeding Reservoir: Grand Central Reservoir & Tower
Elevation Delta vs Base: 64.0 m below reservoir
Cut-off Threshold: Drops when reservoir < 35%
Current Water Status: šŸ”“ Bone Dry / Zero Flow
Repressurization Lag: +18 hours after valves reopen
Air locked; starved by downstream draw. Pressure requires >3.2 bar static head to crest Bekker Rd.
VS
LOW-LYING VALLEY

Lower Vorna Valley (Anton Hartman)

1,480 m AMSL (55m lower)
Feeding Reservoir: Grand Central Reservoir & Tower
Elevation Delta vs Base: 119.0 m below reservoir
Cut-off Threshold: Maintains flow down to 10%
Current Water Status: šŸŸ¢ Low to Moderate Pressure
Repressurization Lag: 0 ā€“ 2 hours after valves reopen
Gravity sump. Benefits from hydrostatic downward head. Water pools here first even during throttling.
