Inter Continental, Mumbai

Concerns:

  • Hotel had setup a Sewage Treatment Plant (STP) of around 600 KL / day capacity
  • The treated water was to be used for various secondary applications like Cooling tower makeup, gardening and public area washing.
  • The STP  installed was not performing, which made Hotel authorities to stop operating and maintaining the STP
  • The Hotel Engineering team did their best to make the STP functional by contacting various agencies. But no positive output was obtained.
  • The STP had been non operational for around 6 months.
  • The various  treatment tanks were full with waste water and have developed into an anaerobic condition.
  • The existing major equipments including panel at site  were in a bad shape and condition.

Since the STP plant was not functioning, there were issues of very foul smell and loss of around Rs.9, 000/- per day.
(300 KL x Rs 30/kl == Rs.9000/day} i.e around 2,70,000/- per month.
Average water requirement – 300 KL
Tanker Water (@Rs. 30 /KL):  Rs.9000 /day
Water Costs: Rs. 9,000 / day == Rs. 2.70 lacs /month
 
What we did

  • After evaluating  the plant, we assured them that we can streamline the plant and would be able to deliver the desired  quantity of  good quality treated water
  • We took the operation and maintenance of the plant
  • Simultaneously complete analysis of the design of each and individual units, flow patterns, source & frequency of waste water generation, and such related information was gathered and evaluated
  • we started with the  retrofitting  of the plant and was recommissioned for desired results.

Achieved

  • The plant is treating the entire load generated by the hotel
  • Fulfilling all their secondary water requirements.
  • The tanker water requirement has been completely stopped. Thereby reducing the overheads
  • The treated water has outlet parameters like BOD <10, is  smell free, is been used for gardening, flushing and  cooling tower makeup  
  • meeting all pollution control board norms.
  • Finally, the most important for us is the client is fully satisfied with the performance of the plant.
