For those contaminants that can be degraded, the resulting metabolites may still have antimicrobial or selective activity. Many microbial and chemical contaminants in wastewater cannot be degraded by the treatment process or inactivated through disinfection of the effluent. Influent can be contaminated with a variety of pollutants, including antimicrobial agents, pharmaceuticals, personal care products, and heavy metals, which can accumulate within WWTPs. WWTPs are relatively nutrient-rich, heavily contaminated environments that receive waste from a variety of AMRD-loaded environments, including hospitals, industrial and agricultural sites and release both solid and liquid by-products that can disseminate AMRDs. WWTPs are a significant point source for AMRDs and antimicrobials. Liss, in Management of Emerging Public Health Issues and Risks, 2019 2.3.3.1 Wastewater Treatment Plants as a Point of Control We are in continuing liaison to address RFI’s and queries related to the project to ensure the construction phase is completed efficiently.Haley Sanderson. Construction has been quoted and proposed to be commence in Q2, 2021. PCE was able to overcome each challenge presented to deliver the HVC design and associated SER in the agreed timeframe. The report was a lengthy process however, demonstrated the impact was acceptable and covered all impacts related to vegetation clearing from the kiosk unit, to the entry and exit points of the under bore. The issue was raised with Ausgrid who requested an ecology assessment to be completed. The proposed HVC location required some vegetation removal. The resolution was negotiated by demonstrating if we changed the 2-5 construction to a 2-1 construction the mains would operate within the allowable separation clearances.Ĥ. Both cases Ausgrid argued the existing OH mains angle was not able to have a UGOH construction and a 2-5 construction would not allow for a UGOH construction, in addition mid-span clashing was flagged due to the OH construction 2-1 to 2-5. A solution was proposed to UGOH at the next pole which was met with rejection also. The point of interconnection was rejected by Ausgrid initially. To finally establish a loop (N-1 contingency) for switch B, the HVC was designed to interconnect to the existing OH HV network.

Through negotiating with Ausgrid compliance, the option to install a stay was approved, allowing the pole to remain and reduce the costs to the customer.ģ.

At the end of the line by decommissioning the mains (CCT180) the final pole (HV-61359) was no longer structurally compliant which was required to be replaced and upgraded. To address the existing OH clearance non-compliance all existing poles within the site required decommissioning. The report was issued to Ausgrid installation inspectors for review which resulted in approval for our design in favour of the client.Ģ.

The negotiation with Ausgrid included a report detailing the protection results for a non-standard installation. NSW SiR requires a MSB to be located within 30m of the Point of Common Coupling. The location was met with several issues:ġ. The design addressed the network standards non-compliance by establishing a new location for a HVC Unit at the site frontage. Overhead line clearance from ground is not to correct standard and creates a hazard for delivery trucks at site.In addition, there were other issues related to operation and safety: Requirement of appropriate Service Protection Device.Currently the RMU is operated by both Ausgrid and the client and Ausgrid and the client would require separate switching HV installations.The High Voltage Connections would need to be brought up to modern standards.
#Wwtp design standards upgrade
Toronto WWTP completed minor restoration/upgrade work during a previous High Voltage Upgrade completed in 2014, at which time Ausgrid indicated that any future contestable works to the electrical apparatus at Toronto would necessitate the following upgrades: In addition, existing OH line clearance was required to be rectified due to non-compliance with current Network Standards (NS220). The site was required to be upgraded to a new HV supply, consisting of a single Ausgrid HVC installation with a “RMICB” supply arrangement. Power Control Engineers were engaged for the contestable ASP3 design services relating to the Toronto WWTP HV power upgrade including associated electrical reticulation works.
