Municipal Works Manager — Drainage Grading
Define the finished purpose, reference levels, underlying material condition and the evidence required by the receiving operation. Geometry alone does not establish structural or agronomic performance.
This reference assembles relevant extracts from the guide library. It is general project planning, not a local project report, verified specification or translated technical publication.
Drainage Formation
Drainage formation is the project stage that connects the planned water route through the earthworks. It should be coordinated with structures and crossings.
Before moving material
Set out the drainage profile and receiving outlet.
Receiving operation and checks
Complete erosion protection and inspect the connected route. Measure critical invert and transition levels.
A surface route does not establish drainage capacity or discharge permission.

Working weight influences cutting, traction and ground loading, but weight alone does not establish grading performance. Ballast, a carried load and attachment weight also change the demands on the tractor, hitch and tyres. Consider the complete combination in both loaded and empty states.
Before moving material
Obtain the machine weights, hitch limits and tractor information.
Receiving operation and checks
Use a controlled trial to establish a workable pass depth. Observe slipping, rutting and unstable handling before chasing greater load.
More weight may damage soft ground and does not make a machine suitable for every tractor.

Poor surface drainage can result from a blocked outlet, a reversed fall, a damaged crossing or local depressions. Grading should follow the identified cause.
Before moving material
Trace water from its entry point to the receiving outlet.
Receiving operation and checks
Inspect the drainage route during a suitable water event. Check that the complete route remains connected through boundaries and crossings.
Surface grading cannot remedy every subsurface drainage problem.
