SANITARY SYSTEM


28/53

It is the arrangement provided in a house or building

for collecting or conveying waste water through drain

pipes, by gravity, to join either a public sewer or a

domestic septic tank is termed as house drainage or

building drainage.

INTRODUCTION


29/53

SANITARY SYSTEM


30/53

To maintain healthy conditions in the building

To dispose off waste water as early and quickly as

possible

To avoid the entry of foul gases from the sewer or the

septic tank

To facilitate quick removal of foul matter

To collect and remove waste matters systematically

Soil pipe: A soil pipe is a pipe Through which human excreta flows.

Water Pipe: it is a pipe which carries only the liquid waste. It does not

carry human excreta.

Vent pipe; it is a pipe which is provided for the purpose of theventilation of the system. A vent is open at top and bottom, to facilitate

exit of foul gases. It is carried at least one meter higher than the roof

level.

Rain water pipe: it is a pipe which carries only the rain water.

Anti-siphonage pipe: it is pipe which is installed in the house drainage

to preserve the water seal of traps.

TRAPSA trap is depressed or bent fitting that, when

provided in a drainage system, alwaysremains full of water, thus maintaining waterseal. It prevents the passage of foul air or gasthrough it, though it allows the sewage or

waste water to flow through it. The depth ofwater seal is the vertical distance between thecrown and dip of a trap. The depth of waterseal represents its strength or effectiveness.Greater the depth of water seal moreeffective is the trap. The depth of water sealvaries from 25mm to 75mm.

ONE PIPE SYSTEMIn the system all soil

and waste waterdischarge into onecommon pipe and allbranch ventilatingpipes into one main

ventilating pipe. Thissystem largely replacesthe two pipe systemand lent itself very well

to use in multi storeydevelopments. It is farmore economical thanthe two pipe system.


49/53

TWO PIPE SYSTEM

The waste stack received the

discharge ablutionary fitments andconveyed this to the ground levelwhere it was delivered above thewater seal in a trapped gullyconnected to the drainage system.

the soil stack receives thedischarge from soil appliances anddelivered it direct to theunderground drainage system. Thewaste and soil water did notcombine until they reached thebelow ground drainage system.

THE FULLY VENTILATED


50/53

THE FULLY VENTILATEDONE-PIPE SYSTEMA large number of sanitary

appliances in ranges.

Each trap with an anti-siphon or vent pipeconnected to the discharge

pipe in direction of the flowof water at a point between75 - 450 mm from trapcrown.

Vent stack connected to thedischarge stack near to thebend to remove compressedair at this point


51/53

The single stack systemReduces the cost of soil and wastesystems.

Branch vent pipes are not required

To prevent loss of trap water seals:-

The trap water seals on the waste

traps must be 76 mm deep.

The slopes of the branch pipes are:sink and bath, 18 to 19 mm/m;basin 20-120 mm/m; WC 18 mm/m

(min.).

Vertical stack at 200 mm below thecentre of the WC branchconnection.

Modified single stacksystem

Close grouping of the sanitaryappliances install the branch wasteand soil pipes without the need forindividual branch ventilating pipes.

To prevent the loss of trap water seals

WC branch pipe min. 100 mm boreand the angle = 90.5 to 95.To prevent the loss of trap water seals basin main waste pipe min. 50 mmbore and the angle = 91 to 92.5.Five basins or more / length of themain waste pipe exceeds 4.5 m a25 mm bore vent pipe connected tomain waste pipe at a point betweenthe two basins farthest from the stack.
