4.1-4 Water-saving campaign and toilet paper reduction program (Figure 4.1-4)

(Figure 4.1-4 Water-saving campaign and toilet paper reduction program)

4.1-5 To reduce using water in toilet by filling water in 2 bottles water, placing the water bottles in the water tank at the back of the toilet. This method is not to obstruct the entrance of the water. Then close the rear tank lid. Try Pressing the toilet flush as usual. The water can be saved about 3 litres per each. (Figure 4.1-5)

(Figure 4.1-5 Reduce water use from toilet)

4.1-6 Water Management Project by controlling weed around the surrounding areas which helps tobalance the water conservation and doesn’t cause sewage in the canal and wastewater treatment.     (Figure 4.1-6)

4.1-8 Water Management Project can solve drainage clogs, clean up pipes / canals, and improve a drainage system for flood management (Figure 4.1-8)

(Figure 4.1-8 Water Management Project to solve drainage clogs, clean up pipes / canals)

4.1-9 To check the 150-horsepower pump system for life long service and to prevent repairiug frequently. All pumps should have the records of the maintenance in using and timetables for a punctual monitoring and maintenance. (Figure 4.1-9)

(Figure 4.1-9 Checking the pump system.)

4.1-10 Collection of rainwater

— Precipitation reservoir for sterilization. Water-saving campaigns has been developed in using water saving tap (see Figure 4.1-10)

(Figure 4.1-10 rain water reservoirs)

(Figure 4.1-10 Rainwater Collection)

4.1-11 Underground water storage tanks

Ngamwongwan parking lot 2 is equipped with underground water storage tanks in order to prevent potential land subsidence with the space saving and stable water temperature. (Figure 4.1-11)

(Figure 4.1-11 Underground water storage tanks)

4.1-12 Building ponds / lakes for keeping water

— Kasetsart University Kamphaengsaen Campus builds the 7 wells of ponds and lakes for keeping water to use. Wells in the area are approximately 416 rai. One well in 130 rai can produce for tap water of 48,000 cubic meters / year. (Figure 4.1-12)

Well No. 1 in 150 rai can produce tap water of 48,000 cubic meters / year.

Well No. 2 in 50 rai                                      Well No. 3 in 80 rai

Well No. 4 in 80 rai                                     Well No. 5 in 80 rai

Well No. 6 in 70 rai                                     Well No. 7 in 40 rai

(Figure 4.1-12 Water storage at Kamphaeng Saen Campus)

Kasetsart University Chalermphrakiat Sakon Nakhon Province Campus has 7 water reservoirs including Kalasin Reservoir, Nakhon Phanom Reservoir, Mukdahan Reservoir, Sakon Nakhon Reservoir, Nong Khai Reservoir and Udon Thani Reservoir. Total 1,400,000 cubic meters of water are collected from each reservoir for using in agricultural research areas (Figure 4.1-13).

4.2-1 Recycling Waste Water from ponds, natural ponds for lawns and trees.

— To install water pumps by using sprinklers within the wastewater treatment ponds for watering the lawn.

— To use water from natural ponds, for watering trees to replace tap water (Figure 4.2-1)

(Figure 4.2-1 installing the water pump using sprinklers)

(Figure 4.2-1 Usin water from natural ponds and watering trees to replace tap water)

4.2-2 using of treated water in flushing toilets

— To recycle Water of KU Dairy Center using for cleaning floors and flushing toilets.

  Reverse Osmosis Soft

drink production of Kasetsart University with Filters and Reverse Osmosis Systems

1.Water is flowed through the sand, carbon

2.Then run into Reverse Osmosis and resin strainers.

3. It cannot produce drinking water flows into the tube and then separates from the tank.

 4. The water flows in the pipe to the first floor of the building.

5. Then, flow in the pipe which is connected to the tank on the first floor.

6. The water is kept in the pump for daily use.

        7 .The recycled water is used for cleaning up the floor.             8. Using recycled water in flushing the toilets.

4.2-4 Water Recycling System in Tilapia Hatchery

Water Recycling System in Tilapia Hatchery. The water is used to hatch the fish that is supplied with flowing water all the time. The water from the hatching tubes will flow into the support tray before flowing into the PVC pipe and circulating through the hose to return to the top of the hatching tubes. With this system of rotation can reduce the amount of water needed each day. The amount of water need to be added each day is about 2% of the total system water is about 20 liters.

Kasetsart University uses electrical equipment efficiently, can reduce water consumption more than 75%.

Kasetsart University has been using the electrical equipment efficiently which can reduce water consumption more than 75 percent

4.3-1 Introduction of sanitary wares can save a lot of water based on the principle of using water instead of old water to purify. This way use less water and wash quickly. The push button is located on the top of the water tank with two buttons, which can save up to 3 liters of water (Figure 4.3-1)
