YVW Aims

161616

YVW drivers

Reinstatement accounts for about 30% of our costs; Happy to work towards least community cost; Incentive to minimise these costs; Hoping to be more pro-active with water main renewals.

Currently not getting many bursts so few high priority mains; Currently trying to combine water main renewals with road

resurfacing program: adapting our program with Councils, could councils adapt their program to ours?

171717

Concerns Generally come to agreement with council when water main is on the edge

of road pavement; Difference of opinion arise when YVW main is in the centre of a lane or in

the middle of the street; Requests sometimes include reinstatement beyond Auspec guidelines YVW’s understanding of reinstatement requirements:

• the importance of a straight cut, • not having a join where the wheel will run• council concern when the road is new and YVW puts a trench through it• importance of preventing water ingress.

Road management clause: “return the road back to its existing condition prior to the works” unclear what exactly this means.

Areas to work on with council

Keep working on the relationship to get best outcome for the community; Common aim is a happy customer

Better guidelines about reasonable extent of reinstatement: Previous attempts to build upon, perhaps revisit work completed in 2006;

Ensuring water main renewals and roadworks programs align as much as possible;

Maintaining the quality of our reinstatement Any benefits from working with MAV? Closer working with councils in major commercial high profile areas Happy to receive feedback from council so that we can learn and improve. Education on good road repair practices and council issues
