1 Sustainability in practice AYALA WATER & ECOLOGY LTD Eli Cohen, M.Sc.

2 Sustainability = minimal human and technology involvement

3 Ecological systems base on two main principles: Flow of energy Cycle of materials

4 Design criteria for sustainable system: All materials are degradable Solar energy is yet available and create no side effects Gravity as moving force Healthy environment support healthy plants which are a powerful supporters of microorganisms communities Poly-cultural systems are stable and stronger System hydraulics Landscape

5 Ayala s Natural Biological System (NBS) Comprehensive hybrid system : Hydrology methods: (gravity) horizontal flow, vertical flow, upflow, free-water and tidal-flow Different types of plants - Larger variety of microorganisms, higher durability, better biological degradation of contaminants Varity of aggregates differ physically and chemically

6 different Hydrological methods: horizontal flow, vertical flow, up-flow, free-water, tidal-flow, etc.

8 Different types of plants (bigger variety of microorganisms, higher durability, better biological degradation of contaminants)

9 different types of sediments varied physically and chemically,

10 NBS advantages Long lasting, self sustaining phytobiological systems Very low maintenance costs with minimal energy involvement. High endurance under extreme water flows and contaminant loads. No by-products such as sludge or saline water Part of the local landscape and environment.

59 Design and work principles: Locating sources of pollutions and treatment on-site Survey and construction is being done by local professionals Using local sediments and plants Using local labor as much as possible Minimal use of electricity Recycling of non-degradable elements

60 Plaine du Var & town of Nice project West8 architects, Rotterdam - leading office

61 Main issues to be confront by designing team: Flooding hazards Contamination of the upper and lower level aquifers Rehabilitating the Mediterranean nature of the valley Preserving wild life and vegetation The concept should be based on sustainability approach which means using as much as possible only natural solutions

62 Design concept: On-site sustainable solutions: Storm & surface water buffers Water harvesting and infiltration to upper aquifer On-site sewage treatment as part of parks and landscape Redesign of river bed,

69 The Company AYALA Water & Ecology was created from the belief that nature s laws can control and cure the environment with minimal involvement of human and advanced technologies. Since 1989, we have planned, designed and constructed hundreds of self sustaining natural-ecological water bodies.

70 Questions regularly asked: Do natural systems are feasible any where and to any pollution? Are they economical? Are they easily marketed and well excepted?

71 Sustainability design with nature inevitable approach for healthier environment
