Resource conservation in the infrastructure planning of an Aerotropolis township

Resource conservation in the infrastructure planning of an Aerotropolis township

Scope:

Design and project management of integrated infrastructure for the township of 1,700 acres covering water, sewerage, drainage, solid waste management, fire, disaster management, electrical distribution, telecommunication, safety and security aspects.

Value Added:

The solution proposed included rainwater harvesting and water management designed to retain 22 ponds covering over 11 hectares of area. These ponds are being preserved and over 300 ml of rainwater will be harvested in these ponds. The drainage system has been planned to route the surface water runoff surrounding through these ponds. The annual mass balance for the ponds reveals that at least, minimum water level will be maintained through summer.

Based on zero discharge concept, sewage generated from the township is proposed to be treated by Sequential Batch Reactor ( SBR ) process at the sewage treatment plant. It is proposed to provide tertiary treatment. Post tertiary treatment, the treated sewage water will be used for flushing and irrigation. The prescribed solution will result in 50% reduction of fresh water intake from 38 mld to 18 mld.
