Iran Water Research Institute Toward Integrated Urban Water

Iran Water Research Institute Toward Integrated Urban Water Management Homayoon Sabbaghzadeh Mohammad Riahi Water Research Institute ((WRI )) 5 th World Water Forum ((WWF 5)) Session 6. 2. 3

Iran Water Research Institute th 5 WWF Slogan BRIDGING DIVIDES FOR WATER

KEY QUESTIONS ? ? ? ? Iran Water Research Institute Q 1 : How can we use technology to enable us to better manage the urban water cycle? Q 2 : Is the limiting factor technology or institutional frameworks (or a combination of both)? Q 3 : Why have we not yet moved to an integrated approach to urban water management? Q 4: Would a single digital earth model (e. g. Google. Earth Integrated Water Model), help us view the urban water cycle in a more holistic way?

Urban Water Paradigm Iran Water Research Institute The water trinity: Ø Water supply Ø Stormwater Ø Wastewater • Dominates our thinking and world view • In fact there is only one system!

Urban Water Cycle Iran Water Research Institute Precipitation Water supply infrastructure Domestic allotments Commercial /industrial allotments Other Wastewater infrastructure Stormwater infrastructure Receiving waters

Iran Water Research Institute • • • • • Application of Integrated Urban Water Management Have policy and planning frameworks and organizational structures which facilitate innovation Think carefully about the process to be followed when embarking on an IUWM project Set clear, measurable objectives and assess options and outcomes against them Consider other dimensions of sustainability beyond water There is power in partnerships, either formal or informal Begin dialogue with authorities and community early Assess the validity of assumptions Get the right skills and form a strong, solution focused team Focus on the local context of the site in question Consider urban form and landscape potential before focusing on infrastructure Think divergently, then progressively converge on the preferred option Use workshops as a design tool and communication forum Stay focused on the original objectives and maintain design integrity throughout Communicate well Use appropriate costing, financial and economic assessment Select appropriate technical analysis and design tools Monitor and assess performance against design estimates

Iran Water Research Institute Consider all dimensions of sustainability Consider other sustainability considerations such as energy, materials, biodiversity, and inter -and intra-generational equity

Iran Water Research Institute Form a strong, solution focused team Have a multi-disciplinary integrated team: • urban planning • environmental science • engineering; environmental, civil and chemical • landscaping • surveying • marketing • economics • social science

Iran Water Research Institute Important Role of Measurement & Data • If you don’t measure No Data • No Data (or can’t get the data) Knowledge Lack • Lack Knowledge Poor Understanding • Poor Understanding Ineffective Planning • Ineffective Planning Bad Management • Bad Management Business failure

Iran Water Research Institute Important Role of Measurement & Data • If you don’t measure it you won’t understand it • If you don’t understand it you can’t model it • If you can’t model it you can’t predict it • If you can’t predict it your ability to manage it will be constrained largely to the application of reactive measures
