Over clay over limestone and shale as the plain tilts up into the escarpment, surfaces are regraded to pits and pipes laid with checked fall rather than relying on the ground to take water.

What goes wrong on Glen Osmond jobs, and how it is avoided
The problems listed come off this ground and this housing stock rather than a generic list. Each one changes the scope, and each is priced as its own line rather than buried in a rate.
01
Ground: clay over limestone and shale as the plain tilts up into the escarpment, which decides the trench depth and the soakage.
02
A scope that named one job on the quote and delivered another on site
03
Access or levels discovered after the price was agreed, forcing a variation
04
Work sequenced out of order, so finished surfaces are trafficked by the next trade
05
Drainage left to chance, so the finished work moves or ponds in its first winter
06
A boundary detail agreed verbally with one neighbour and disputed by the other
How it goes
The order the work happens in at Glen Osmond
Drainage is surveyed before it is dug: levels establish where water enters and leaves, the design fixes pits, pipes and grades, trenches are cut, lines laid and tested, pits set, and surfaces regraded and reinstated. Work at Glen Osmond is booked around the foothills band, where winter run-off arrives from the slope above, so the stages that are weather sensitive are not left to chance.
01
The problem: A waterlogged yard in July — standing water, dying lawn, mud to the back door.
02
Survey: Levels are shot across the site; the water's path (and where it stalls) is mapped.
03
Earthworks: Cut and fill reshapes the site — high ground lowered, hollows filled, falls established.
04
Trenching: Stormwater trenches are cut to grade, falling continuously to the discharge point.
05
Ag-pipe: Slotted ag-pipe wrapped in geofabric is bedded in screened aggregate — the underground drainage web.
06
Pits: Collection pits and channel drains are set at the low points and connected.
07
Backfill: Trenches are backfilled and compacted; surfaces are reinstated over the top.
08
Raining: The same site in the rain — water moving, pooling nowhere, gone in minutes.
