Established in 1877 and situated in Melbourne’s Ringwood East, Tintern Grammar is one of Australia’s longest-standing schools. Set on over 16 hectares of landscaped gardens and sporting grounds in the City of Maroondah LGA, the prestigious site features expansive facilities, including an indoor swimming pool, STEAM centre and a working farm.
Tintern Grammar’s newest extension will see the relocation of the school’s facilities building – with two new structures built to accommodate an assortment of workshop areas, washbays, storage and office space.
Site objectives include designing water quality and quantity assets to meet stormwater management, treatment and reuse requirements – and to align with WSUD (Water Sensitive Urban Design) and ESD (Environmentally Sustainable Design) frameworks to help create a sustainable, eco-friendly space.
Designing Stormwater Solutions for Condensed Site Footprints
AtlanFlow SN8 HDPE Pipe is a practical approach for meeting the challenges of the site, which required the deployment of detention infrastructure in a long, shallow and narrow footprint between the two proposed buildings.
Typically used in conveyance applications, AtlanFlow is finding increasing use in detention scenarios, where the ability to lay long lengths of pipe in shallow excavations is an economical alternative to traditional OSD systems. This novel solution is ideal for sites with restricted excavation depth, condensed footprints and trafficability requirements.
Three rows of 600mm diameter pipe with 60 metres of total length will provide 50,000 litres of OSD volume – installed with minimum cover to AS/NZS 3500.3:2018 standards and compliant with AS/NZS 5065 standards for suitability in drainage applications.
Locally manufactured at our state-of-the-art production facilities in Albury, New South Wales, AtlanFlow is suitable for local conditions and environmental pressures – and provides sustainability gains, carbon reductions and freight efficiencies over imported alternatives.
Delivered ready to install in 6-metre lengths with prefitted seals, the modular design of this solution is a key benefit. Prebundled for safety and efficiency, AtlanFlow is easy to handle on-site – expediting project timelines, particularly compared to cast-in-situ alternatives.
An adjacent pit will house an AtlanFilter for tertiary filtration, which uses upflow treatment to maximise filter surface area for high-performance pollution removal.
As part of our SQIDEP verified (Stormwater Quality Improvement Device Evaluation Protocol) treatment range, AtlanFilter has verified removal efficiencies of 85% Total Suspended Solids, 74% Total Phosphorus, and 59% Total Nitrogen. The design of this filter cartridge system features an automatic backwash action that dislodges particulates from the filtration after storm events, which helps to lower maintenance requirements and enhance filter media lifecycles.
By providing these assets in a low-footprint combination, AtlanFlow and AtlanFilter will ensure an efficient and economical solution – while maintaining site surface yield and developable space for the school’s new buildings.
These solutions will help to futureproof Tintern Grammar with generational stormwater assets to enhance the school’s sustainability – ensuring Joy in Water for future generations.
