Water Reticulation Projects in Upper Hunter
Design Villages Reticulation Project
ADW Johnson was engaged by Upper Hunter Shire Council (UHSC) to develop and prepare the concept and detailed design documentation for water reticulation systems for the villages of Blandford, Wingen, Parkville, Middlebrook and Gundy. The villages are not currently serviced with a reticulated potable water supply system and instead most residents rely on private bores and rainwater tanks to source water. The reticulated water supply systems for the villages will provide a safe and secure water supply.
Planning
ADW Johnson prepared the Review of Environmental Factors (REF) for each village reticulated potable water supply system to assess the potential for environmental impacts of the project and provide safeguards for the construction and operation of the assets. The REF was prepared in accordance with Sections 5.5 & 5,7 of the EP&A Act. The REF included the engagement and management of various subconsultants including noise and vibrations, ecology, aboriginal archaeology and European heritage.
Surveying
Detail survey of the proposed water reticulation alignment was undertaken for the proposed reservoir locations, watercourse crossings and intersections. Survey pickup included details and levels of all significant topographical features, visible services, drainage infrastructure, cadastral boundaries and basic ground proofing of Lidar and DCDB spatial data to verify due to the large area of land to cover for each site. Electronic data was made available to engineers for the preparation and drafting of the watermain concept and detailed design.
Engineering
ADW Johnson developed the concept and detailed design documentation, drawings and specifications for Council to include as part of the construction tender documentation. The design phase included preliminary alignment of mains to service customers identified by Council, hydraulic modelling to determine adequate pipe sizing in accordance with the Water Supply Code of Australia, pressure management, transient pressures, cyclic fatigue analysis and all civil and mechanical design of headworks assets such as reservoir, booster pumping stations and pressure reducing valves necessary for each village water supply network. The design included the management and engagement of various subconsultants necessary for the design including geotechnical and quantity surveyor for detailed cost estimates.
