CIV4261 INTEGRATED URBAN WATER MANAGEMENT

GROUP 3

Executive Summary Horizons Engineering present the second part of a four-part Integrated Urban Water Management (IUWM) Strategy for Troups Creek Catchment. Following client feedback from stage 1, the high-level goals and their respective objective/indicators and targets are revised and a total of three high-level goals each with a different purpose, that is, integration of stormwater management, protection and enhancement of natural water systems, and maximising economic contribution and social vitality are presented. A base case with minimal treatment and two alternative cases along with their respective IUWM strategies are presented and the effectiveness gauged against the base case through a cost and water flux savings analysis. All cases share the same proposed eight storey mixed development that incorporates 2240 dwellings, 320 commercial lots, and public open spaces of 6.62ha. The site sits between Abeckett Road and Robinson Road in the undeveloped region and occupies 17ha. Water infrastructure extensions total 600m to the site area and 1100m within the development for the water supply network, 4200m for both the minor and major drainage network, 900m for the sewer network and 718m for the road network. The base case practices minimal/zero integration between its water infrastructure and provides minimal/zero treatment for its stormwater and wastewater. Potable water is suggested for both potable and non-portable demand while treatment for minor drainage stormwater is provided according to South East Water’s: Troups Creek Stormwater Recycling Project (South East Water, 2016) to meet the Sustainable Neighborhoods Clause 56 of the Victoria Planning Provisions (Perera, 2016). Untreated wastewater is collected separately via blackwater and greywater sewage lines and channeled to the Eastern Treatment Plant. Alternative 1 termed Eco – Lite uses water-efficient fittings and fixtures (e.g. dual flushes, excellent shower taps and mixers, etc.), proposes stormwater measures such as pervious pavements, Siphonic Roofwater Harvesting system and Rainwater Tank, and greywater treatment measures like the Modified Drawer Compacted Sand Filter (MDSF) Greywater Treatment System. The second alternative termed Green Palette proposes efficient fittings and fixtures, stormwater measures and rain harvesting measures such as rain gardens, green roofs, and constructed wetlands, Living Walls Greywater Treatment, and a Smart Water System. The non – structural measures include central planning within township with institutional controls such as implementation of regulations, economic incentives to provide concessions, subsidies to achieve lower demand and education and campaigns to achieve sustainable results. The water flux and balance for the entire catchment was calculated to identify catchment water consumption. The water flux for the base case, Eco – Lite, and Green Palette total 10,638,829, 9,946,686, and 10,227,274 kL/yr respectively. Eco – Lite and Green Palette report potable water supply reductions of 70.02% and 71.3%, wastewater discharge reduction of 77.67% and 85.8%, increases in runoff of 1.17% and 1.7%, and reduction of total suspended solids (TSS), total phosphorus (TP) and total nitrogen of 97%, 90%, 81% and 92.7%, 80%, 80% respectively. Both cases were weighed against several criteria of which efficiency, removal percentage, cost, and water flux savings played vital roles in determining the recommended solution. Final recommendations include a combination of both cases with the mixed development utilising the siphonic roofwater harvesting and the existing dwellings applicating the extensive green roofs. Stormwater harvesting for reuse saw the recommendation of pervious pavement and wetland with the former situated throughout the catchment and the latter at the east in the underdeveloped region. Lastly, the Modified Drawer Compacted Sand Filter greywater treatment and water efficient fixtures and fitting from Eco – Lite are recommended.
