CONTROLLED DISCHARGE TOILET SYSTEM FOR INDIAN RAILWAY

COACHES (BROAD GAUGE)

1. SCOPE

A controlled discharge toilet system retains the black water/toilet waste and

discharges when the speed of the coach is equal to or more than the designated

speed and a preprogrammed number of flush cycles have been completed.

This specification covers the design & general requirements including supply,

installation & commissioning of controlled discharge toilet systems along with

stainless steel inlays for ICF type and Low Cost SS (Stainless Steel) coaches and

only pan for LHB type coach with FRP Modular Lavatory. The tenderer should

offer clause wise comments and shall also submit deviation statement. Comments

such as „noted‟ are not acceptable where compliance is warranted. Failure to

adhere to this clause will render the offer invalid.

1.1 OBJECTIVES

A controlled discharge system as opposed to conventional systems shall ensure:

i) Clean, odourless, hygienic, aesthetically pleasing toilet

ii) No dumping of waste in stations and surrounding area

iii) No spilling of waste on bogie parts, under gears or rails

iv) Low operational and maintenance cost

2. OPERATING CONDITION:

The controlled discharge toilet system should function with full efficiency under

the following operating conditions:

2.1 Ambient Conditions:

2.1.1 -40C to 55

0C with 100% humidity and dust. Temperature variations can be quite

high in the same journey or short period of time.

2.1.2 Coaches may operate in areas where there may be continued exposure to salt laden

air.

2.2 Water Supply:

2.2.1 There is one tank of 40/30 ltr. capacity available over each toilet roof at both ends,

at a height of about 1940 mm from toilet floor in AC coaches of both ICF and

LHB type. Water is pumped to these from under-frame mounted main water tanks.

Water-flow to the flushing valve is by gravity.

2.2.2 There is one tank of 450 ltr capacity available over each toilet roof at both ends at

a height of 2030 mm from toilet floor in ICF type non-AC coaches. The capacity

of the tank for LHB non-AC coaches is 385/365 ltrs. These tanks are not

pressurized and the water flow from these tanks is by gravity.

2.3 Pneumatic Supply:

2.3.1 A limited quantity of air supply of 15 lit/min./Coach can be made available at 6

Kg/cm2 for the toilet system, if needed.

2.3.2 Air supply will not be available in some conditions of operation, such as prolonged

shut down of locomotive, coach being stranded for some purpose, coach

undergoing maintenance in depot etc.

2.4 Vacuum Generation:

No arrangements exist in Indian Railway Coaches.

2.5 Power Supply:

2.5.1 110 V DC supply is available from the coach circuits. This supply varies from 90-

140 V with 15% ripple. No transformer should be used for dropping voltage

from110 V in ICF type coaches. However, 24V DC supply level with a tolerance

of +25% and -30% is also available in LHB/ Low Cost SS AC Coaches.

2.5.2 415 V 3-phases AC 50 Hz is also available in Rajdhani Express type coaches only.

2.5.3 Upto 200 Watts will be made available for the four toilets in a coach.

2.6 Car-body dynamics:

±100 mm vertically

±55 mm laterally

±10 mm longitudinally

± 40 bogie rotation about centre pivot

Minimum clearance between the rail level and any part of the CDTS should be 225

mm under tare condition.

2.7 Duty Cycle:

2.7.1 The toilet should be ready for use by the next passenger within two minute.

2.7.2 The toilet shall be used upto approx 150 times in 24 hrs. Journey time varies upto

80 hours.

2.8 Maintenance conditions:

2.8.1 The toilet interiors are cleaned using cleaning agents, mild acids, caustic soda etc.

High-pressure jets are used during journey halts. In case any electronic

be indicated.

3.4 It shall be robust, reliable and require low maintenance. This should be quantified

with mean time between failures (MTBF) and mean time to repair (MTTR).

3.5 The system should not require any ground facilities at the terminals or enroute

stations for its operation.

3.6 Clear interface drawings including bracketry required for the positive mounting of

the retention tanks and method of transfer of waste from the toilet bowl to tank and

then to ground should be clearly explained. Stainless steel inlay with an integrated

Indian pan in single piece should be offered for ICF type & Low Cost SS Coaches.
