Drainage Sump Spraying

The City of Stirling employed an experienced and licensed contractor in May 2006 to undertake weed spraying around 138 of its drainage sumps.  

The combination of the herbicide and the lowest winter rainfall on record resulted in the decline or loss of approximately 400 trees and shrubs, some of which were on 49 privately owned properties adjoining some of these drainage sumps.  

The City of Stirling deeply regrets that this has occurred and staff are personally saddened by the loss of vegetation.  

What has the City of Stirling done to rectify the problem so far?
The City of Stirling and its contractor have contacted the 49 affected residents and many have accepted the City’s proposal to remove and replace declining or lost trees and shrubs. Those who have done so have been satisfied with the work carried out. The City will continue its remediation and reinstatement works according to the affected resident’s wishes. These works are being carried out by the City’s contractor at no cost to the City or affected residents.  

In addition the City of Stirling has introduced strict new measures and controls relating to weed management, which will significantly minimise the risk of reoccurrence. Changes include slashing of weeds and mulching sump batters.  

What have we planned for the future?
The City of Stirling is currently working on a rehabilitation program for all drainage sumps, which will see widespread plantings commencing in winter 2008.  

In addition the City of Stirling is also investigating alternative means of managing stormwater as a broader strategy to improve amenity across the region.
