  1. 1. SUSTAINABILITY IN PRACTICE Musi River Watershed and Hyderabad Golf Course as a Case Study By Ayala Natural Biological Systems
  2. 2. The Musi River has putrefied near Hyderabad
  3. 3. Untreated Sewage Flows are Normal
  4. 4. THE CASE STUDY – Phase 1 of the overall challenge  The Hyderabad Golf Association faced an irrigation deficit of approximately 2MLD of good quality water  Due to its important historic location, HGA was mandated to improve the quality of surface ponds within the new fort (Naya Qila), by governmental mandate  The only ‘available’ water source, aside from trucks and tap water, are nalas carrying varying quantity of smelly, unsightly sewage through the golf course
  5. 5. BIRD’S EYE VIEW Polluted Pond- In need of rehabilitation by government mandate Moat (sewage overflow), Naya Qila fort walls Jamil Kunta Lake
  6. 6. Shortfall of 2MLD irrigation waterNearby urban effluents Two Crisis Situations… Simultaneous overabundance yet lack of water
  7. 7. The Natural Biological System
  8. 8. The NBS Completely energy free treatment and oxygenation in an aesthetic package
  9. 9. The NBS
  10. 10. The raw sewage settling tank • Floating mattress- odour barrier and nutrient removal
  11. 11. Rejuvenation of a lake on the course
  12. 12. Regulatory Compliance-Tertiary quality water
