28. STP retrofit:
Aeration tank
Construction defect did not allow the required aeration. Inlet were moved as far as possible from
outlet to allow new water to stay longer in the tank
Outlet
After refurbishment, S T P does not require any more chemicals

29. Kitchen effluents (grease) and B3 management:
Achievement:
- “zero-risk” methane gas emission
- Bacteria control
- Reduction of smell from the grease
trap, in the corridor area.
- a reduction of 33% grease & oil in the
effluents
- solid waste removal:
Feb 2016: 30 bags / day
Dec 2017: 10 bags / day
Steps:
- identify weaknesses in the system, due to aging equipment and
outdated technology.
- Monitoring of water production.
- analyze the system performances.
- increase the effluent water quality.
- reduce necessity to mix with clean water.

techniques

32. Hands on training
Engineering staff Housekeeping staff

33. Several trainings on water
conservation potentials and
water stewardship
Internal and external:
• Training for “non-technical” staff, including
sales, security guards or masjid keeper.
• Several coordination meetings organized
with subcontractors to review procedures
and identify improvement potentials
• Swimming Pool,
• HVAC,

a. Piping System:
a. Reduction of scale deposit
b. Disintegration of already existing deposits
c. Corrosion protection
d. Increased water pressure
e. Rust minimization
b. Technical appliances
a. Chillers: compressors load is reduced
b. Cooling towers: reduced biofilm and fouling
c. Boilers / Water Heaters: heating systems regain full performances
d. Kitchen appliances
e. Grease Trap
f. Laundry and washing machines
g. Cleaner bathrooms
!
Energy consumption reduced
while overall activity generated
an increase of 7% of revenue.

45. Tomorrow is NOW:
• Water Efficiency definitely bring financial benefits
• Water Demand management is the answer for:
• Over-consumption from big water users
• Deep wells usage
• Waste Water management
• Jakarta Water Security
• We want to cooperate with responsible building owners dedicated to
Jakarta Government efforts.
• Jakarta could become a “Laboratory” towards “Green-City” concept.
