1. ENGINEERING PLUMBING AND SANITATION
Applies Disposal System of Dirty Water/Drainage

2. Sewerage Basis Divisible tailing water is devided into four factions:
1) Sewerage : tailing water comes from closet, flushing, bidet, and tailing water contains of night soil coming from other plambing devices.
2) Scar water : tailing water comes from other plambing devices, like bathing tub ( bath tub), basin cleans hand and kettle basin

3. 3) Rainwater : from roof and yard
4) Special tailing water :contains of gas, poison, or dangerous material like the one comes from mill, tailing water from laboratory, place of therapy and place of inspection in the hospital.

4. WATER DISPOSAL OF SYSTEM CLASSIFICATION
(1) Classification is according to tailing water type :
(a) Sewerage disposal system
(b) Disposal system of scar water
(c) Storm drain system

5. Part and parcel of disposal system is traps and pipe van
Purpose of disposal principle system is to flow tailing water within exit building, into installation of processing or roil public, without generating pollution to area of bilding itself.

7. Conditions for traps : 1. Cover conclusion water depth
This cover conclusion of water depth usually ranges from 50 mm to 100 mm.
2. Its construction must be in such a way to earn always clean and doesn't cause tantalum impurity

8. 3. Construction of traps must be in such a way that function of water as " cover conclusion" can be still fulfilled.
4. construction of traps must be in simple form that is easy to clean it because impurity deposit over and over will remain happened.

15. Traps attached by device plambing :
1. Type traps " P"
Snared this certifiable type and very stable if it is attached pipe ven.
Type traps " S“
In this type, Japan often apply, especially in the case of building wall is insufficient thick; if it is applied by type traps " P", disposal pipe will pierce into room side.

23. Prohibition to install double traps
The concerned doubled traps here erection two traipses serially in direction of tailing current from device plumbing.
In erection said tailing water time to pass traps after downstream, cover conclusion water in traps above stream will be inhaled, so that it will pursue tailing water

24. Traps in storm drain
If storm drain pipe will be jointed to dirty water pipe or scar water, need to be attached traps at division is leveling off the rainwater tailing pipe.

28. Erection of Dirty Water Pipe
Some factors we need to pay attention :
1. Diameter blow-off pipe
Pipe diameter may not minimize and must be adapted for device unit payload plumbing.

29. Sewerage application pipe puts down as near by possible with WC.
2. Pipe length :
Interval of device plumbing with tailing water of application pipe labors is not too length, at the most
Sewerage application pipe puts down as near by possible with WC.

31. 3. Pipe dip :
Dip of pipe in application is very important in dirty water pipe, if determination of dip in wrong pipe can influence speed to flow tailing water, danger of gagging as the result of impurity ex- man tailing.

35. 4. Roughness at pipe inner surface :
Surface roughness in this pipe has influence to speed of tailing current .
Theoretical of best speed in pipe ranges from 0,6 to 1,2 m/second. If speed of current threw away less than 0,6 m/second hence impurity in tailing water can twang which in the end will be able to cork pipe.
On that account blow-off pipe in general applies pipe PVC in another type pipe

36. 5. Tacking on pipe :
In this case instalatur must work truly, otherwise pipe connection is easy to leak or happened blowby, for this avoided the case because permeable water from dumper pipe hardly smelling is not delicious.

37. 6. Pipe brace :
To avoid pipe gets out of joint or peripatetic pipe when is being utilized. To eliminate thing we need to be attached pipe brace.

39. Sewerage Disposal System
In principle ,there are 2 ways of that is :
1. Mixture systems : In this disposal systems is between sewerages and scar water collected and poured into one flows.
