The Hyderabad Golf Association faced a shortage of 2 million liters per day (MLD) of quality irrigation water. Additionally, the government mandated improving the quality of surface ponds near the golf course that were polluted with untreated sewage. The Natural Biological System was implemented as a case study to address both issues. It treats 3 MLD of sewage on-site without energy and produces tertiary quality water for irrigation, rejuvenating the ponds. Water quality tests showed significant reductions in parameters like COD, BOD, and fecal coliform after treatment. The system provides a green, aesthetic and cost-effective solution to water and wastewater challenges.

3. The Musi River has putrefied near
Hyderabad

4. Untreated Sewage Flows are Normal

5. 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
