The access officer updates the status of the site access in CIS to reflect that the worker/s has left the site. Major works permit process When is a Major Works Permit (MWP) required The MWP allows Seqwater to apply specific risk controls to manage work activities that will impact, or are assessed as posing a high risk of impacting on Seqwater operations. risk matrix contained in the Enterprise Risk Management Framework () Seqwater’s must be used to assess the risks associated with performing work activities at Seqwater. When assessing the risks associated with performing a work activity, consideration must be given to the criticality of the asset being worked on and the impact that the work will have on Seqwater operations. The table below details that triggers that will require a MWP to be used. Function MWP Trigger Water Supply Sole source WTP work activity will disrupt, or has a high risk of – disrupting the continuous supply of drinking water to customers. Networked WTP work activity will result, or has a high risk of – resulting in storage reservoirs falling below normal operating levels. Network Assets work activity will disrupt, or has a high risk of – disrupting the continuous supply of drinking water to customers. Raw Water Off-takes / Raw Water Mains work activity will – impact, or has a high risk of impacting the supply of raw water to a WTP. Third Party Activities work activity undertaken by a third party – that will impact, or has a high risk of impacting on the operation of water supply assets (i.e. water retailer operations, electricity disruptions, telecommunications disruptions). Water Quality Raw Water Quality work activity will impact, or has a high risk – of impacting the raw water quality at a WTP intake (not including dam flood releases). Produced Water Quality work activity will impact, or has a – high risk of impacting the quality of drinking water produced from a WTP. Water Quality Monitoring work activity will prevent, or has a – high risk of preventing the monitoring of drinking water quality critical control points (does not include routine maintenance tasks e.g. cleaning and calibrating a turbidity meter). Flood Dam Gates work activity will prevent, or has a high risk of – Management preventing the ability to control releases of water from a dam gate Assets or other water release structure.
