  1. Storm Water Project ‘Proposed for co-financing under the 2007-2013 Programming Period

  2. Structure of the Presentation Part One • Background and Context of “The Project” – originally one project area Part Two • The Project as a National Storm Water Project – rethinking with various components Part Three • Milestones – for submitting the Project Application

  3. (Part One)Background and Context • 2004-2006 Originated as the ‘Birkirkara-Msida Flood Relief Project’ and submitted in the OP 1 • 2006-2007 The Storm Water Master Plan focused on it as the Priority Project • 2007-2008 JASPERS assistance identified other options and carried out economic analysis • 2006 to 2008 MEPA – led us to prepare an Environmental Appraisal Report (EAR) • 2008 and on … further liaison with MEPA: rethinking original project in view of all the above

  4. 2004-2006‘Birkirkara-Msida Flood Relief Project’ • Major projects for flood relief taken by Government, especially following the September 2003 floods • Projects executed/proposed in Qormi/Marsa and Burmarrad areas while designs were developed for Birkirkara-Msida localities • Underground solution deemed most suitable for the Birkirkara-Msida areas but entailed much higher costs • Project submitted under OP 1 with targets: • Creation of infrastructure with potential of 720,000 cu m reuse • Reduction of flooding from 5 in 1 year to 1 in 5 year events 2006 Birkirkara-Msida Flood Relief Proposal

  5. 2006-2007Storm Water Master Plan (SWMP) • Contract was awarded to TAHAL in September 2006 and is still being managed under the lead of WSC • The SWMP consultants were required to harmonise ongoing projects and strategic vision of The Plan together • The SWMP focuses on Birkirkara-Msida as a priority and gives six alternatives, including tunnels and/or culverts • SWMP also makes proposals for other localities and for water conservation at larger geographical scale • SWMP Final Draft completed in November 2007 and review and final revision are also ongoing • The SEA on the SWMP was commenced in 2007 (ongoing) SWMP Birkirkara-Msida Alternatives

  6. 2007-2008 JASPERS Assistance • Reviewed TAHAL’s proposals as basis for Birkirkara-Msida project application but remarked on gaps in: • Higher level National Water Policy • SWMP strategic vision (resonating the above) • Concern over economic viability of the earlier SD and TAHAL’s proposals for Birkirkara-Msida • Identified other smaller-scale alternatives. • Options Analysis carried out on a new set of alternatives. • Economically preferred option not same as SWMP proposal • Smaller tunnels under Birkirkara-Msida and discharge to Ta’ Xbiex. Alternatives Identified for Options Analysis

  7. 2006 to 2008MEPA and the EAR • October 2006 Submission of a PDS to start EIA of the ‘Birkirkara-Msida Flood Relief Project’ as submitted in OP 1 • April 2007 - Further details with alternatives (by TAHAL) given to MEPA in a bid to obtain EIA TORs • June 2007 – Draft TORs received from MEPA – generic and all inclusive and requiring Environmental Appraisal of Alternatives and a revised PDS prior to the EIA TORs • 2008 – EAR carried out on the range of alternative studied by JASPERS (incl. SD’s and TAHAL’s main proposals): • SD’s (large tunnels) environmentally most preferable • Small tunnels + Ta’ Xbiex discharge, second best

  8. 2008 and on … • Issues pertaining to the OP 1 have arisen because of the performance targets and nature of the project vis-à-vis: • Simply resizing of the project to make it feasible brings it far below the original 720,000 cu m target for reuse. • Water conservation from Birkirkara-Msida alone has itself also been shown to be untenable, making the project a flood relief project.

  9. Further liaison with the MEPA • Upon completion of the SWMP Final Draft and other alternatives for the Options Analysis: • Environmental implications of all sites concerned were looked into • Other (in some cases more) appropriate sites and forms of development were identified • Preliminary site assessments and draft EIA TORs if works are to be proposed on the sites • Consultative rethinking of the project

  10. A rethinking of the original project is aimed to: • Improve Economic Feasibility by: • Limit scale of costly Birkirkara-Msida tunnels component and • Maximise on other flood relief benefits nation-wide and integrate these into water conservation interventions as far as possible • Reinforce Environmental Nature by: • Aiming at OP quantitative targets for water conservation through aquifer recharge, attainable by inter-linking catchment areas • Selecting sites with least environmental issues and best scope for integrating flood relief and water conservation • Improve Environmental Acceptability by: • Avoiding highly problematic sites altogether • Scaling down development in possibly sensitive sites • Scaling up of interventions and rehabilitation of dilapidated sites • Re-Package proposals as a National Storm Water Project

  11. (Part Two) The National Storm Water Project ‘To manage storm water away from where it is a hazard to where it is a resource.’

  12. Purpose and Aims A Multi-Pronged Storm Water Project that aims to: • Integrate flood relief and water conservation needs at local and national levels as far as practical • Make interventions for specific needs in seven different urban/rural areas • Develop infrastructure that is suitable for future management of catchments and watercourses • Adopt a catchment-based approach to address issues originating beyond the local level and holistically

  13. Concerns in Urban Areas Flooding in Urban Areas • Highest levels of risk to life and property in the most densely populated areas • Need to divert concentrated water run-off efficiently • Flooding is most acute in the most developed areas due to urbanisation of original watercourse and valley beds • Most difficult to construct large storm water infrastructure • Most difficult to retain water for reuse • High levels of investment in flood prone areas • Land is scarce and expensive Urbanisation and Flood Prone Areas Flood Aftermath

  14. Concerns in Rural Areas • Need to create and connect larger water bodies • Existing water harvesting infrastructure is scattered and difficult integrate with water reuse • Enhance water storage capacity in rural areas • Coordinate efforts aquifer recharge • Need for rehabilitation of watercourses • Mitigate problems rural and downstream urban areas • Ensure proper management and better water reuse/conservation along the watercourse • Integrated Valley Management:Wider Environmental, Social and Economic Values • Ecological rehabilitation of dilapidated sites • Creation of amenity value • Tourism, Recreation and Cultural heritage • Scientific Importance and education Flooding in non-urban areas Catchment Areas and Water Reuse Infrastructure

  15. Project Components Geographic Scope • Focuses mainly on seven large basins: • Includes specific flood relief and water conservation measures depending on locality and catchment conditions • Controls the risks and damages associated with flash floods and storm events of up to 1 in 5 year magnitude with direct benefits to between 4 and 5 % of the population. • Integrates flood relief with water conservation to enhance water harvesting and recharge potential of Malta's largest catchments by more than 2 million cu m per annum.

  16. Birkirkara-Msida • Mainly for the protection of life and property in the densely populated Birkirkara, Msida, Balzan and other localities • Also minimise inconvenience and traffic congestion during and after average rain events for the larger population • Provide scope for selective harvesting of runoff, and link to other catchments for aquifer recharge Counted Dependent on other catchments 1200 3,300 150,000 200,000 45,000,000 19,300,000
