for the upgrade works includes for pH correction of the existing treated water which involves conveyance of the feed water via an underground pipeline, 800mm in diameter & 50m long, to a new feed water sump, located adjacent to a new pump station. The pump station, approximately 110 m2 in footprint area & approximately 6.5m high houses 4 pump sets required to pump the feed water to a set of 4 degassers, with approximate dimensions 3m in diameter 8 meters high. Following degassing, the water is dosed with chemicals & returned to the treated water storage tank via a 800mm in diameter and approximately 50m long underground pipeline. Provision for overflow & draining has been allowed for from the sumps (treated & raw water) to the existing wastewater lagoon via a underground pipeline connecting to the existing plant liquid residuals collection network. Six new tanks varying in diameter from 3-5m with a maximum height of 7m, are required to store chemicals for the new treatment process. An existing road will be extended by 120m, between 5 - 12m wide, to facilitate the delivery of chemicals to the new footprint. A new pipeline, 200mm in diameter, approximately 150m long, is required for additional residual treatment in an existing tank. This application includes a Natura Impact Statement
