Chapter F7 Maintenance and operation of roads
F7.3 W/C 113: Routine drainage maintenance
Definition: work category 113
Routine drainage maintenance
This work category provides for the routine care of drainage facilities to maintain their function.
Examples of qualifying activities
Examples of qualifying activities include:
- cleaning of kerbed water channels, sumps and cesspits in urban areas (30 percent of total cost - see below)
- routine maintenance, repair and reinstatement of surface water channels and routine maintenance and repair of sub-soil drains
- stream clearing and debris removal to maintain water courses through culverts (cross-sectional area less than 3.4 square metres)
- removal of berms impeding drainage.
Street cleaning
The NZTA has determined that funding assistance will be provided for 30 percent of the total cost of cleaning channels, sumps and cesspits in urban areas, as an approximation of the benefit to the road and its users.
Approved organisations shall only show the 30 percent of the total expenditure that is eligible for funding assistance in their land transport programmes.
The 30 percent component of the total cost of cleaning on state highways in urban areas is to be funded within the state highway maintenance programme. The remaining 70 percent balance will remain a territorial authority amenity cost with no funding assistance.

Exclusions
This work category excludes:
- the general sweeping of the carriageway surface on both state highways and local roads - this is not eligible for funding assistance
- the full cost of sweeping to remove surplus chip immediately following resealing -this is part of the maintenance chip seal project cost funded under work category 212: sealed road resurfacing
- maintenance of land drains - even though land drains may be situated in the road reserve, their maintenance is the responsibility of the relevant drainage authority. However, if the drains are also used as road drainage facilities, then funding assistance under this work category may be approved by the NZTA on the basis of the proportion of the catchment areas.
