NU6 #4 by ROMAN M. CRUZ - saving water


SAVE WATER PROJECT
NU6 #4
Submitted by: Roman M. Cruz


In the fastfood restaurant I am currently engaged right now, water will always be an integral part of our operations. We use water when cooking our foods, incleaning our tools and utensils, cooking equipments , walls, floors ceilings and even our perimeter areas. Without water, we cannot provide the best food, service and cleanliness for our customers. A recent development due to the exponential growth of the population and the continuous use and abuse of this resource has caused a pressing concern in our society as a whole. A recent study conducted by the Japan International Cooperation Agency (JICA) says that in 2025, if we will not conserve water, there maybe some problems. The Philippines, is facing a water crisis over the next ten years unless sources are developed to meet growing demand. With the aforementioned facts above, our group has lead to think about ways on how we can properly optimize the use of water in our stores in support also for the PD 1067 or the Water Code of the Philippines.

Enter the Manitowoc ice machine maker. As a backgrounder, the said equipment function is to produce ice for our daily usage on our drinks, on cooking different ingredients and for in-process procedures such as putting the different ingredients over ice to maintain their required attributes. The ice machine, for its one full cycle of harvest it consumed roughly more than 4 liters of purified water. With this amount of water, only 3 liters of water will be formed into cube ice (good for usage of approximately 20-25 orders or regular drinks). The remaining 1liter of purified water to which we call it as backflow product will just eventually go to the backflow pipe and just be put into waste.

Our group has found a eureka of opportunity in order to make good use of this excess water! We connected a pvc pipe on the backflow pipe of the machine and provided a container in which all the excess purified water will be contained.  The water collected is being recycled and we are using it in cleaning our perimeter areas, floors, walls and different tools and utensils.  With this innovative idea, in one 24 hour operation, we can roughly collected excess 60-80 liters water that we can put into good use .3
