Sustainability =
minimal human and technology involvement

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

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 microorganismscommunities
• Poly-cultural systems are stable and stronger • System hydraulics• Landscape

Ayala’sNatural Biological System (NBS)
Comprehensive hybrid system :– Hydrology methods: (gravity)
horizontal flow, vertical flow, up-flow, 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

NBS advantages• Long lasting, self sustaining phyto-
biological 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.

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
