R.A. Bill shall be minimum Rs. 50,00,000/- (including cost of materials).
5. MATERIAL TESTING
Necessary material testing shall be carried out by contractor at AMC laboratory at his own
cost as directed by Engineer-in-charge. The material testing fee at the rate 0.5% shall be
deducted from every running bill of the contractor. This does not relieve contractor from his
contractual obligations of making all the arrangements for taking samples during each
concreting, curing for the specified period as per specifications, bring to the laboratory and
keeping the necessary records as directed. At the time of final bill, the amount deducted from
each running bill shall be adjusted with the actual material testing fees and the balance
amount, if any will be refunded to or recovered from the contractor.
6. CHILD LABOUR
The contractor shall not employ any child below 14 years of age. It is prohibited by Child
Labour Prohibition and Regulation Act. 1986. Honorable Supreme Court has given guidelines
and as per those guidelines, if child labour is employed on the work site, the contractor shall
have to deposit Rs. 20000 (Rupees Twenty Thousand Only) in the child labour welfare fund.
If the contractor refuses to deposit this sum, then the action will be taken for contempt of
Supreme Court Judgement and also will be Prosecuted by the concerned authority. In case of
provision of Child Labour Prohibition and Regulation Act,1986 by the contractor and to that
Municipal Corporation shall recover the amount from the contractor.

D2:- SAFE ENTRY AND WORKING IN SEWER LINES – GUIDELINES
SAFE WORK PRACTICE PRINCIPLES
1. Introduction
These general guidelines are intended to assist the Contractor in the development of safe
work practices. Where the risk assessment indicates that a particular hazard cannot be
present, the precautions to control that hazard do not apply. Remember that a favorable
history does not guarantee absence of hazard on this occasion.
2. Confined Space
“Confined Space”, in relation to a place of work, means a space of any volume which a
person may at any time enter or be allowed to be entered in which the atmosphere is liable
at any time to be oxygen deficient. This includes but not limited to pipes, sewers, Machine
holes, tunnels, shafts, ducts, other similarsewerage installations and etc.
The Contractor shall develop acceptable work practices and safe entry procedures based
on the guidelines provided hereunder and the AMC’s safety code on safety precautions to
be observed during sewer desilting / lining work.
3. Notification to Work in Confined Space
The Contractor shall obtain an entry permit from the Engineer for each occupancy of any
confined space. The Contractor shall furnish all required details in an approved format to
the Engineer for permission to work in confined space at least 24 hours prior to the entry.
Where prolonged work is involved, the permit must be renewed for each shift. An
incident, which substantially alters the condition of a confined space entry, requires
immediate evacuation and reassessment of the condition.
4. Air Quality and Ventilation
Contaminant control and effective ventilation are major factors influencing air quality in a
confined space. The ventilation must be adequate to clear pre-existing contaminated air
and maintain a respirable atmosphere during planned work. This ventilation may be
permanently installed or portable equipment used for this task. For general ventilation,
fresh air should be supplied to the workplace. Within the sewer system this creates an
environment, which displaces contaminated air in the immediate vicinity.
Where a task generates atmospheric contaminants in a specific area e.g. use of chemical
such as polyester resin, adequate local exhaust ventilation should be used to remove the
contaminants. Where failure of the mechanical ventilation system would result in
deterioration of air quality, the controls must be clearly tagged to prevent accidental
interference and the ventilation system monitored while the confined space is occupied.
Self-Rescuers must be carried whenever failure of the ventilation system or changes in the
working environment can create a contaminated atmosphere. The self-rescuer can be a
self-contained breathing
apparatus, oxygen self-rescuer, or short duration self-contained breathingapparatus,
depending on the time taken to reach open air.
Note: Obtain occupational hygiene advice on the selection or performance of ventilation
system where this is not specified in the work practice or plant design.
Any regularly accessed confined space should be illuminated to AS 1680 or equivalent
with electrical installation to AS 3000 or equivalent. Portable lighting may be used to
supplement permanent lighting in the workplace. Temporary mains powered lighting
installed for a task must comply with the requirements of AS 2865 or equivalent Indian
Standards. Miners lamps, mounted on a safety helmet may be used as an alternative to a
hand held torch for personal illumination.
Unless portable lighting complies with AS 2380.7 or similar Indian Standard the
possibility of a flammable atmosphere must be eliminated by isolation, cleaning,
ventilation purging etc.
Where the confined space has been proclaimed as a flammable gas hazard area to AS
2430 or similar standard all fixed and temporary electrical installation must comply with
AS 2381 or equivalent standard. Torches and portable lights must comply with AS
or equivalent standard.
Illumination standards are: -
General Lighting: - 40 lux minimum, equivalent to a poorlylit
room Stairway Lighting: - 80 lux minimum
Task Lighting :- 240 lux minimum (normal workshop requirements)
6. Equipment usage, Standards and Maintenance
All confined space safety equipment as proposed in this tender documents shall also meet
the established international labour safety standards and be of appropriate designed
capacity for the proposed usage at sites. The equipment must be checked for visible
damage and correct operation before each use. Preventative maintenance must be
performed by trained, and where necessary, authorized persons at the intervals
recommended by the equipment manufacturers. The Contractor shall submit to the
Engineer evidence of such periodic check and maintenance of the equipment used for
confined space entry at every first week of the month.
7. Room to Work
When the constricted volume of a worksite prevents normal work postures and tool
movement, the need for special tools or frequent work rotation should be considered.
8. Control of Flooding
When a confined space is normally liquid filled, accidental return to service must be
prevented by double isolation e.g. insertion of suitable blanking piece, plugging with
inflatable plugs, temporary coffer dams as a second isolation in a Machine hole or other
effective means.
9. Flow Control
Where a sewer is entered while flowing, rapid increase in flow must be prevented by use
of stop logs, isolation of pumping stations, weather watch and other means appropriate to
the sewer catchments. Adequate communication with the person responsible for flow
diversion must be maintained for the duration of the entry.
Where deep flowing water is present, use personal flotation devices. Safety harness and
lifeline and safety nets as appropriate to prevent drowning and washing away.
11. Fire and Explosion
Adequate precautions must be taken to minimize the risk of fire or explosion when
entering a confined space for any purpose.
12. Presence of Flammable Gas
The presence of flammable gas, flammable dust or the possibility of the presence of
airborne substances in flammable quantities may create a hazardous Area. Care shall be
taken by the authorized person to determine the presence of any such flammable situation
in the confined space before entry. Smoking or lighting any cigarette or box matches in
confined space shall be strictly prohibited. The flammable gases of concern are methane,
digester gas, vapours from flammable liquid, and vapours from trade waste discharges.
13. Manual Handling of Tools, etc.
Safe system of work should be followed to protect against falls of persons or objects and
crush by moving or falling objects.
Reverberation within a confined space can increase noise levels, especially if more than
one person is working. Heavy duty hearing protection may be required.
15. Vermin / Leptospirosis
All persons working in confined spaces should be aware of the leptospirosis hazard
presented by the presence of vermin. The presence of cockroaches etc. does NOT indicate
that the atmosphere is free of danger to health.
16. Standby and Communication
A member of the confined space work team is allocated the task of maintaining
communication with the members inside the confined spaces. This task may be rotated
among the members of the team. The Standby person must be trained and be physically
capable of providing the assistance and life support in an emergency and must have
sufficient proficiency in Hindi, English, Urdu and Punjabi languages to promptly
communicate information by radio or telephone when required.
While acting as stand-by, this person must not enter the confined space or leave the
vicinity unless relieved from this duty. A standby person is needed for all confined space
entries. The Safe System of Work must indicate the process for communication from the
confined space to the standby e.g. 2 way radio ‘man down’ alarm line of sigh etc.
17. Fitness Assessment
An assessment of fitness, including cardiovascular and respiratory health, is required to
ensure that all persons entering confined spaces, or acting as the stand-by person, can
comply with the physical demands of the job, without risk to their health.
18. Emergency Rescue and First Aid
No person shall enter any confined space, even in an emergency, without first ensuring all
safety requirements have been met. A safety emergency plan may assist in a safe, speedy
response in the event of an emergency.
All confined space work teams must be trained and equipped to sustain life andbe able
to summon emergency help, provide first aid and assist emergency service personnel, if
Trained persons using supplied air breathing apparatus must only attempt rescue of
persons apparently overcome by toxic gases in a sewer or other confined spaces.
Stabilization of other injuries must be prioritized against the availability of breathable air.
19. Gas Detector
The Contractor shall engage an authorized person for gas monitoring and detection. This
person shall be trained to operate and response test gas testing equipment and is
authorized by management to perform the necessary tests to decide whether a category
or 3 confined space is fit to enter.
Gas testing can only be performed by persons trained in gas testing, using equipment
appropriate for the anticipated contaminants. This person can perform other duties
provided these do not conflict with the gas-testing task.
20. Specialist Gas Detector
This person has technical qualifications and acceptable training to operate and response
test gas testing equipment, including hydrocarbon detectors and detector tubes and
assesses portable ventilation systems. He is authorized by management to carry out
atmospheric testing to establish entry conditions for all confined space categories, and to
establish whether a Category 1 confined spacecan be re-classified to a Category 2. He also
performs tests to verify whether hot work is permitted in gas hazard areas.
Where possible, cleaning should be performed without entry to the confinedspace, even if
only preliminary cleaning is possible.
Particular attention should be given to the probability of releasing hydrogen sulphide
when disturbing microbial active sludge and sediments, which have accumulated in a
confined space. Supplied air respiratory protection shall be wornwhere such residues exist
and effective ventilation cannot be guaranteed. Continuous gas monitoring is required
even when supplied air respirator protection is used.
Hose couplings should be designed to resist accidental dislodging or loosening. Both the
operators and the standby person should be able to stop the flow of cleaning material into
the confined space.
Hydro jetting must be performed according to the relevant regulations. Where chemical
compound is used in within the confined space, the chemical compound should be classed
in the Material Safety Data Sheets as non-irritant to respiratory system, eyes and skin. If
this is not possible then appropriate respirator skin and eye protection must be worn.
Substance specific air monitoring may be required.
A visitor to a confined space is a person other than a contractor, who is not a member of
the Confined Space Work team. Visitors must be escorted and trained or inducted in the
necessary skills for that entry and shall sign an indemnity form before entry into a
confined space. No visitor shall be allowed to enter the confined space without prior
permission of Engineer.
23. Hazard Control
Hazards to be identified and controlled include but are not limited to access mechanical
and electrical isolation, flow isolation and control, drowning and engulfment, last known
contents, atmospheric contaminants, temperature extremes, security and public access.
24. Air Quality Standard For Entry
The acceptable limits of some gases in confined spaces are:
Gas/Vapor Present Acceptable Limits
a. Oxygen Content (o) 19.5% to 23.5% by volume
b. Flammable Gas/Vapor 5% of Lower Explosive Level (LEL)
c. Hydrogen Sulphide (H2S) 5 ppm
d. Carbon Monoxide (CO) 10 ppm
25. Carbon Monoxide (CO)
Carbon monoxide is colorless, odorless, flammable and toxic. Its common sources are
fire, motor vehicle exhausts and cigarette smoke.
This gas is a chemical asphyxiant and is readily absorbed by the hemoglobin in the blood.
Then hemoglobin is unable to transport oxygen to the body tissues and the body becomes
oxygen starved. These effects are more pronounced with hard work or for heavy smokers.
Symptoms include headache (50-200ppm), nausea (400ppm), irregular heartbeat
(1200ppm). Collapse and death (2000ppm).
The entry permit limit is 10 Parts Per Million (ppm). Maximum with an IDLH value of
1500 ppm. (IDLH-Immediately Dangerous to Life and Health)
Note: Some gas detecting machine sensors are cross sensitive, H2S being detected by the
CO cell and vice versa. Alarm by either sensor requires evacuation and re-evaluation of
the safe system of work.
26. Flammable Gas/Vapor
A gas or vapor that will burn when mixed with air in certain proportions and
The mixture, which contains the least amount of flammable gases that will explode, is
called the Lower Explosive Limit (LEL). The mixture, which contains just enough
Oxygen to let the flammable gas explode, is called the Upper Explosive Limit (UEL). The
flammable range varies for gases and vapors.
Many of these have toxic effects when inhaled and a Workplace Exposure Standard has
been issued to protect workers from these Gas/Vapor. The Contractor shall obtain relevant
Workplace Exposure Standard (WES) for use in the site.
Gas / Vapour Flammable Range 5% LEL WES
in % (FOR ENTRY PERMIT
Butane 1.9 – 8.5 950 ppm 800 ppm
n-Hexane 1.2 – 6.9 600 ppm 50 ppm
Methane 5 – 15 2500 ppm Axphyxiant
Petrol 1.3 6 650 ppm 900mg/cum
Trichloroethylene 12.5 90 6259 ppm 50 ppm
27. Hydrogen Sulphide (H2S)
Hydrogen Sulphide is a colourless, toxic and flammable gas, which usually has the
odour of rotten eggs. In sewerage systems it is usually derived from the action of bacteria
on the sulphur compounds in anaerobic or old sewage. A smallamount of sludge or slime
in wet wells or sewers will release a lot of H2S when disturbed.
After a few minutes exposure, the ability to smell hydrogen sulphide by a person is lost
and then hydrogen sulphide becomes more dangerous as its presence is no longer
obvious and the person could become an innocent victim.
It can sometimes be detected by odour at less than 0.1 ppm but can be readily detected by
odour at 4 ppm. More serious health effects include eye irritation (10 ppm), respiratory
irritation (50 ppm), headache, nausea, dizziness (200 ppm), collapse and death (700 ppm).
The entry permit limits is 5 parts Per Million (ppm), Maximum with an Immediately
Dangerous to Life and Health (IDLH) value of 300 ppm.
Some gas detecting machine sensors are cross sensitive, H2S being detected by the CO
cell and vice versa. Alarm by either sensor requires evacuation and re- evaluation of the
safe system of work.
28. Methane (CH4)
The most common flammable gas found in sewers is methane. This mainly comes from
gas pipe leaks in the city’s gas distribution system. It can also be derived from the action
of anaerobic bacteria on rotting material. However a range of other flammable gases and
vapours may be encountered. These include LPG, petrol vapour and other solvents.
Digester gas, found in anaerobic sludge digesters on sewage treatment plants is a
flammable mixture of methane nitrogen and carbon dioxide.
Methane is a colourless, odourless gas. Although pure methane is slightly lighter than air
the relative density of methane / air mixture is similar to air entry permit range. Methane
is hazardous because of its flammability, i.e. between concentrations of 5% to 15% in air,
it may explode if an ignition source is present.
High concentrations of methane may result in oxygen deficiency. Injury or death
result from lack of oxygen not methane toxicity classifying methane as a simple
29. Oxygen Content (O2)
Fresh air contains 20.9% oxygen, equivalent to a partial pressure of 211.8 hectopascal of
oxygen at sea level.
The readings obtained on a gas detection instrument in open air may vary depending on
instrument calibration and barometric pressure.
In a confined space, oxygen can be used up by bacteria in sewage or sludge, rusting of
iron fittings, burning (or welding) or displaced (pushed out) by other gases.
Breathing of air, which contains reduced oxygen results in increasingly serious health
effects. These range from impaired coordination and faulty judgment (12- 16% O 2) to
collapse and rapid death (less 6% O2).
Increased oxygen readings can only come from instrument error or by leakage from
oxygen cylinders, liquid oxygen tank, etc. High oxygen levels greatly increase fire
hazards, fires burn fiercely; oily clothing and hair can catch fire without an ignition
The entry permit levels are 19.5% to 23.5% by volume.
Parts per million (ppm)
Parts of gas or vapour per million parts of contaminated air by volume at 200C and
Parts of substance per 100 parts of air,
water etc. 1% = 10,000 P
31. Other Atmospheric Contaminants
Entry, unless wearing air supplies breathing apparatus is not permitted unless atmosphere
contaminants are below the relevant 8-hour time weighted average (TWA) Workplace
Exposure Standard. This limit applies for all entries including brief exposures. Entry
wearing breathing apparatus is only permitted where the concentration of the contaminant
is within the protection factor of the breathing apparatus and below the IDLH
(Immediately Dangerous to Life and Health) value.
32. Sewer Gases
Air in contact with live sewage contains gases released from the sewer. For safe entry,
contaminated air must be replaced with clean air by ventilation of the confined space. The
resulting atmosphere must be confirmed by gas testing.
Discharge of untreated wastes, e.g. hypochlorites, electroplating effluent, acids may result
in generation of chlorine, hydrogen cyanide and other harmful gases some distance from
the original discharge.
33. Confined Space Categorisation
The confined space category is a guide to developing a safe system of work. The confined
space category may change to a more stringent level as a result of adverse environmental
factors or work produces contaminants. Alternatively it may change to a less
restrictive category if appropriate engineering upgrades,
whether temporary or permanent, are implemented.
Category 1 – Confined Space
Entry allowed only if flammable gas is below 5% of L.E.L. and other gases arewithin
the protection factor of the respiratory protective equipment used.
Visibility must be adequate
Personal Safety
o Wear specified protective clothing for the hazards.
o Wear safety harness.
o Use lifeline where appropriate.
Respiratory Protection
o Test air quality prior to entry by a Specialist Gas Detector.
o Ventilate to reduce contamination.
o Monitor air quality as directed by the Specialist Gas Director.
o Wear airline breathing apparatus with backup air supply OR wear self-
contained breathing.
Note: An Oxygen self rescuer is nor a backup for an airline used in contaminated
If the Category 1 confined space is a chemical storage tank, it can be reclassified to a
Category 2 or 3-confined space when the specialist gas detector confirms that the
chemical has been cleared from the interior.
Sewer, wet wells etc can be reclassified by a specialist gas detector to a lesser confined
space only when an approved safe system of work is employed. This safe system of work
must provide for demonstrated control of airborne contaminants and other hazards in the
workplace, to provide conditions equivalent to a Category
Hot work requires control of fire and explosion hazards and may require air supplied
breathing apparatus to control fumes irrespective of the confined space category. A Hot
word permit is required in addition to the normal entry permit.
Category 2 – Confined Space
Entry allowed only if all gases are within entry permit limits. Personal Safety
o Wear specified protective clothing for the hazards.
o Wear safety harness.
o Use lifeline where appropriate.
Respiratory Protection
o Test air quality prior to entry
o If air quality test fails, refuse entry until reason found and rectified, orrevert
to Category 1 entry conditions.
o Ensure adequate ventilation
o Monitor air quality during entry.
o Carry oxygen self rescuer
Note: Standby person must have SCBA readily available.
Hot work requires control of fire and explosion hazards and may require air supplied
breathing apparatus to control fumes irrespective of the confined space category. A Hot
word permit is required in addition to the normal entry permit. A hydrocarbon check by a
“specialist gas detector” is required unless the environment can be upgraded to Category

D3:- SAFETY PRECUATIONS TO BE OBSERVED DURING CLEANING,
DESLITING AND LINING WORK.
1. Special Direction to Tenderers
Precautionary measures to be taken be the contractor for the safety and welfare of
the labours connoted with desilting and lining work.
To begin with the work of desilting, initiall six consecutive Machine holes are
to be opened, two on the up-stream and two on the down-stream side ofthe two
Machine holes, on the actual stretch to be cleaned or desilted. The Machine holes
should be kept open for one hour prior to the starting of cleansing operations and
should be so kept open during the whole duration of cleaning operations. This to be
done for allowing the combustible gasesto escape naturally. No lighted matchsticks
should be thrown in the Machine hole. This may cause fire and explosions
endangering the life of the workmen and the pedestrians. This may also damage to
the sewer and other adjoining utility services, if any Jalis should be placed over all
the opened Machine holes to prevent pedestrians etc. from falling in. tripod stands
with flags it should be written in white bold letters “Danger Machine hole Open.”
When working at night, lantern fitted with red globe and lights shall be hung from
the tripod stand. Each Machine hole kept open should be guarded by one labourer
or C.I. heavy cover with holes exactly fitting up to the fame and capable of
taking the load of lorry should be placed over the Machine hole, so that top of the
cover is flush with the road surface. The contractor without any extra cost shall
provide the covers. The same should be removed and replaced with regular
Machine hole cover when the work is closed.
The contractor should keep sufficient number measurement rods. The measurement
rods shall be made out of solid bamboo/M.S. rod of sufficient length fixed with
M.S. flat 150 mm X 150 mm X 6 mm (6”X6” and ¼”) thick at one end and fitted
with point at other end, to take measurement of water and silt.
Machine holes shall be kept open for minimum one hour to allow foul gases to
escape and simultaneously there should be forced purging with the help or an are
blower to completely clean the air in the sewer.
Sewage levels shall be checked in the Machine holes and the same should not be
more then 450 mm (18”).
Wet lead acetate paper shall be inserted in the Machine holes which should nit turn
even light brown or black. If the lead acetate paper turns light brown or black, then
the Machine hole shows the presence of Hydrogen Sulphide Gas (H2S) and in that
case this test shall be repeated after every tenminutes till positive result is achieved.
The sensitivity of lead acetate paper should be ascertained to suit and detect the
minimum allowable concentration (MAC) for long-term exposure.
This paper should be held as low as possible in the Machine hole atmosphere. In
spite or long waiting for about one and half hour, if he lead acetate paper continues to
show negative gas detector shall be used for half an hour. Thereafter gas detector
shall be used to check the presences of gases and the worker shall be allowed only
after it is confirmed that the condition inside the Machine hole is safe for man entry.
Whenever necessary, or where the sewer line is heavily silted or there are chances of
gas eruption, the person entering the Machine hole shall beprovided with gas mask or
breathing apparatus (respiratory system) and hand blower or mechanical blower be
used during the desilting operation. In every case use of gas monitor in working
condition is mandatory. In additional to this, the conventional methods lie lead
acetate paper test etc. be done. The gas monitors should be accurately calibrated after
regularintervals to maintain their reliability.
After the lead acetate paper test, a lighted safety lamp shall be inserted in the
Machine hole, which should burn smoothly. If not, it shows the presence of Carbon
monoxide (CO) and in that case precautionary measures as stated in sub-pare (g)
should be followed.
After the presence of combustible gases are ruled out the following further tests is
required to be carried out for the presence of oxygen.
A lighted naked candle placed at the center of the candle testing equipment covered
with glass on three sides should be lowered down slowly. If the flame is
extinguished or flickers, it indicates the presence of carbon monoxide and or carbon
dioxide. If it burns for not less than five minutes uniformly, it indicates the presence
of oxygen, which is required for breathing for the workman working inside the
2. Working Inside the Machine Hole
After all these tests are carried out successfully, particular care should be taken where
sewer is heavily silted, the scum and sullage should thoroughly be stirred and
disturbed by means of long bamboos/ G.I. rod from the top of the Machine hole to
allow entrapped gases within silt pockets to escape before allowing the labourers to
go down into the Machine hole.
The depth of water should be measured and the labourer should be asked to
get down when the level of water is less then 450 mm (18”). Before the labourer is
allowed to get down inside the Machine hole, he should be asked to apply barrier
creams all over the body as a precautionary measures to safe guard against itching
and burning sensation. Safety belt should be tied around his waist and chest when
the labourers are getting down, another man at the top should hold the other end of
the rope. Not less then two people should be allowed to work inside the Machine
hole at a time.
If the labourers who are working inside the Machine hole show slight discomfort,
they should be asked to come up or pulled up. The labourers who are working
inside the Machine hole should give jerks every few minutes to signify that
everything is okay with them.
After getting satisfactory test result and after taking precautionary measures as stated
above, the worker shall be allowed to descend or enter in the Machine hole. The
workers entering the Machine hole shall be provided with wadder suit, hand gloves
protective head gears and head lamp. If the wadder suits are not available the
worker shall be provided with Barrier Creams with germicide to be applied to their
entire body to prevent harmful effect due to contact with harmful bacteria and germs.
The worker entering the Machine hole shall wear Harness belt around his waist. In
spite of the Machine hole entry tests being carried out, there are chances of eruption
of poisonous gasses in the silt. If the worker finds any difficulty in breathing initially
or during the work then he should be taken out immediately by means of harness belt.
Where the sewer line is heavily silted or there are chances of gas eruption, gas mask
shall be used while entering the Machine hole and also during desilting.
On completion of the work all Machine holes shall be checked and it should be
ascertained that the same are properly closed.
3. Safety (General)
Proper ventilation shall be maintained in the Machine hole and sewer line being
desilted. Hand operated or mechanical blower should be preferable used for half an
hour to one hour before entering the sewer line even after getting the safe working
condition, while desilting sewer lines where accumulation of silt is heavy. While the
blowers shall be operated continuously during the desilting of sewer lines which are
heavily silted or susceptible to gas generation.
While carrying out desisting, the sewer lines of man-entry size, the contractors shall
use blower during the entire period. This would not only ensure safe condition but
also ensure comfortable working condition for the worker and would in turn increase
his performance and output.
In some Machine hole where sewage is falling over workman or causing obstruction,
plugging the upstream sewer will be allowed temporarily without
any charges, provided the Contractor ensures that the upstream sewer line does not
overflow. The plugs shall be removed immediately after the work has been
The Contractor shall, as far as possible, use mechanical process for cleaning and
desilting sewer lines and progressively minimise manual process of desilting so that
entry of workers in the sewers for purpose of cleaning and desilting shall be avoided.
