management

In order to measure and control water consumption instantaneously, automated meters
were installed. Valve positions were adjusted to ideal consumption rate. Leakage between
pools were stopped by the barriers fitted in. A warning/alarm system was fitted to provide
instant intervention ability in the case of an excessive water consumption. We have experi-
enced difficulty in determining what areas were to be intervened because of the closed loop
system in processes, and we benefited from our team members’ experiences and skills in
overcoming this. The targeted consumption reduction of 30% was realized as 34%.

Economic: The implementation of the project yielded 58,000 US
+ Dollars a year return.

Social: We prevented wasting of water that would serve the needs of
Results hundreds of thousands of people every year.

Environmental: By consuming an unrenewable natural source of ours
less, we managed to leave 24,500 tons of water back in the earth.
Corporate: We built a constant tracking system within 6 sigma control
plans.

Borusan Mannesmann Improvement of

Water Use in Gemlik Rinsing Baths

While reducing the water consumed in the rinsing baths in ERW Factory Completion Lines
by about 30%, we managed to discharge less polluted water out to the water treatment
facility thanks to the revision of the chemicals used in the rinsing baths in order to increase
the cleaning effect of the baths on the manufactured pipes. We have aimed to save on both
water and chemicals by making this discharged water reusable.

Because the pre-rinsing baths were made of steel sheets, they corroded very rapidly due to
low pH, which required us to replace the re-rinsing baths in all three facilities.

+ Economic: An additional cost of 43,154 US Dollars was accrued.

Environmental: We reduced the waste water load coming to the
Results treatment facility by discharging less water with same water pollution,
thereby reducing the operational cost at the treatment facility.
