3.2 O & M of individual components of water works:-

3.2.1 Source and Intake Works

(a) Sanitary Survey – A regular survey of the catchment area such as potential threat to quality of water due to industrial, domestic or agricultural reason should be made and if any threat is found, it should be immediately reported to the pollution control board.

(b) Measurement of flow–in caseof spring, rivers, canals etc., there should be a permanent arrangement for recording daily flow near the intake works. Rain gauge stations should be established to record daily rainfall in the reservoir catchment. In case of reservoir, the regime tables for filling and emptying of storages should be maintained for each year.

3.2.4 Maintenance of Pumps and Pumping Machinery

3.2.4.1 PERIODIC INSPECTION AND TEST

The maintenance schedule should enlist items to be attended to at different periods, such as daily, semi-annually, annually, etc.

3.2.4.2 DAILY OBSERVATIONS

During the previous A Log-book should be maintained to record the observations, which should cover the following items.

i) Timing when the pump was run during the previous 24 hours,

ii) At the time of observation, whether the leakage through the stuffing box is alright,

iii) bearing temperature/s.

iv) whether any undue noise or vibration,

v) reading of pressure, voltage and current

3.2.4.3 SEMI ANNUAL INSPECTION

ii) cleaning and oiling of the gland bolts,

iii) inspection of the packing and repacking, if necessary,

iv) alignment of the pump and the drive,

v) cleaning of oil lubricated bearings and replenishing fresh oil, If bearings are grease lubricated, the condition of the grease should be checked and replaced/replenished to correct quantity.. An antifriction bearing should have its housing so packed with grease that the void spaces in the bearings and the housing be 1/3 to 1/2 filled with greases. A fully packed housing will cause the bearing to overheat and will result in reduced life of the bearing.

3.2.4.4 ANNUAL INSPECTION

i) cleaning and the examination of all bearings for flaws developed, if any.

ii) Examination of shaft sleeves for wear or scour.

iii) Checking clearances.

iv) Impeller hubs and vane tips should be checked for any pitting or erosion.

v) End play of the bearings should be checked.

vi) All instruments and flow meters should be recalibrated.

vii) Pump should be tested to determine whether proper performance is being obtained. In the case of vertical turbine pumps, the inspection can be bi-annual. Annual inspection is not advisable, because it involves disturbing the alignment and clearances.

3.2.4.5 FACILITIES FOR MAINTENANCE AND REPAIRS

A. Consumables and Lubricants

Adequate stock of such items as gland packing’s, belts, lubricating’s oils, greases should be maintained.

B. Replacement Spares

To avoid downtime, a stock of fast moving spares should be maintained. A set of recommended spares for two years of trouble free operation should be ordered along with the pump.

C. Repair work-shop

The repair workshop should be equipped with :

Tools such as bearing, pullers, clamps, pipe wrenches, etc.

General-purpose machinery such as welding set, grinder, blower, drilling machine, etc.

3.2.5 Maintenance of transmission systems

The transmission mains would include raw/ treated water pumping as well as gravity mains from source to treatment works, treatment works to master balancing reservoir (MBR) and from M.B.R.s to service reservoirs in the distribution system. The maintenance problems to be attended to for various types of pipes used in the system are summarized below:-

(a) M.S. pipes laid above ground :-

(i) Pipes should be painted at least once in five years to prevent corrosion.

(ii) Appurtenances such as sluice valves, air valves, expansion joints, rollers should be checked, cleaned at least twice a year and worn out parts replaced. The cleaning and lubrication of rollers should also be done twice a year, preferably pre and post monsoon.

(iii) Expansion joints should be inspected every month.

(iv) The catch drains provided for the portion of water mains laid in cutting should be cleaned before onset of monsoon so that no water accumulates in the cutting portion, resulting in uplift pressure on pipes.

(b) All pipes:-

Sufficient stocks of spare pipes and specials should be maintained for replacement of damaged ones

(ii) Regular leak detection surveys should be under taken particularly for bursting of pipes and leaky joints.

(iii) A detailed record of break down and leaks observed and repaired should be maintained section wise so that more vulnerable lengths could be identified and special measures to repair/ replace them could be undertaken.

(iv) A regular schedule of inspection and attendance to all valves including air and scour valves should be drawn up and the same followed scrupulously. Special attention should be given to air valves.

3.3 O & M of WaterTreatment Plants

3.3.1 Problems

The person in charge of the maintenance and operation of water treatment plant should have a thorough knowledge of the functions of the several units under his control. The problems that may be posed before him may relate to those arising from (a) poor design (b) faulty execution (c) special situation during operation.

A resourceful operator should be in a position to bring to the notice of the concerned person, any faults in design and execution giving rise to problem during the course of operation and rectify them immediately. The other problems which are to be tackled at the operational stage are mainly those which arise out of :

(a) Fluctuations in the quality of the water;

(b) Fluctuations in the quantity and the changes in the flow pattern.

(c) Malfunctioning of the unit(s); and

(d) Mechanical and electrical equipment.

3.3.2 Requirements –

Maintenance should be carried out in a manner which prevents emergencies and unscheduled shutdowns. An efficient maintenance requires considerable skill which can only be acquired by experience, study and practice. Basically, any maintenance programme should observe the following general rules:

(a) Keep a set of plans giving details of the several units and indicating the layout and position of all pipelines and appurtenances ;

(b) Establish a systematic plan of daily operation;

(c) Establish a routine schedule for inspection of machinery and lubrication and maintain records thereof. Instructions for lubrication, the type of lubricant suggested and frequency of lubrication should be drawn out.

(d) Main data and record of each piece of equipment giving details of cleaning and replacement of worn parts and other data of importance such as unusual incidents on faulty operating conditions. Details for any special equipment should be obtained from manufacturers.

(e) Keep a record of analysis of water collected at various points from the source to the distribution system and observation on the effect of such quality on the several units of operation; and

(f) List out safety measures including good housekeeping,

3.3.3 RAW WATER

The problem will mainly relate to the change in the quality of the raw water due to natural causes and by inadvertent pollution of the source.

In the case of a river source, a sanitary survey of the catchment area should be undertaken at regular intervals and water samples taken at significant points where pollution is likely to take place. The analysis of these samples will reveal the degree and nature of pollution and thus help in taking the necessary measures to check or control the pollution. If the fluctuations in quality are rapid, the surveys should be undertaken at shorter intervals. Turbidity is not a special problem as the dosage of the coagulant is adjusted on a daily routine. On the other hand a sudden rise in chlorides content will indicate pollution most probably due to sewage. In such cases, more confirmatory test should be undertaken such as for nitrogen in its various forms, dissolved oxygen, oxygen absorbed and chlorine demand to help the operator to decide whether pollution has taken place and to fix the dose of per chlorination needed.

In the case of a lake as a source the periodical biological and physical examination of the samples will indicate if there is any need for control of algae which may lead to taste and odor problems or clogging of filters. Samples taken at different depths in the lake will indicate the level at which water should be drawn to get the best quality of the water.

3.3.4 FLOW MEASURING DEVICES

Float sump should be periodically cleaned to see that silt does not accumulate which may affect the proper functioning of the float. Charts and pen recorders should be stocked adequately. Annual or more frequent calibration of these devices is necessary Annual servicing and checking of the instruments in imperative.

3.3.5 CHEMICAL FEEDING UNIT

Alum preparation tank is to be painted annually by anti-corrosive paint. V-notch weirs and floats and floating arrangements should be cleaned daily. Enough spares for the mixing device in the chemical preparation should be stocked. Setting of the V-notch should be checked periodically.

Sometimes, if the alum dosing equipment is not in order, the alum slabs are just dumped in the raw water channel. This is bad practice and should not be adopted as it will mean wastage of alum and improper dosing of alum. Alum should be made into a solution and dispensed until the dosing equipment is rectified. The optimum dosing of alum and coagulant aids should be based on a proper and detailed laboratory study including Jar Test. The chemical feeding rate should be controlled, depending upon the needs from time to time.

3.3.6 RAPID MIXER

Adequate spares should be kept ready in stock for timely replacement when necessary. Life of the equipment could be prolonged by periodical painting with anticorrosive paints.

3.3.7 SLOW MIXER

Slow Mixer should be operated continuously for avoiding sludge build-up. All equipment should be painted with anti-corrosive paints every year. Mechanical devices should be properly lubricated and worn out parts replaced. In non-mechanical type of flocculators like baffle and tangential flow tanks, desludgingat least once in six months is necessary.

3.3.8 CLARIFIER OR SEDIMENTATION TANK

Annual overhauling and repainting of the unit should be done a month or two prior to monsoon.

Sludge lines should be kept free of chokages. The lines should be flushed with high pressure water if chokages are noticed. The telescopic sludge discharge device, when provided, should be checked for free vertical movement and O-rings replaced when

as well as problems from sludge build-up. Outlet weirs should be kept cleaned at all times. Algaecide or bleaching powder may be used for controlling biological growth on weirs.

The important features in the operation of a clarifier are:

(a) The introduction of water into the tank with a minimum turbulence;

leaky.

The traction wheels should be checked for alignment and rubber wheels replaced, if required. The unit should be worked continuously to protect the mechanical parts from ill-effects of corrosion,malfunctioning etc.,

(b) The prevention of short –circuiting between inlet and outlet; and

(c) The removal of the effluent with the minimum of disturbance to avoid settled material being carried out of the tank.

Very often, a basin which is not functioning properly can be modified by making changes to the inlet and outlet devices by installing stilling baffles so as to improve any or all of the important features mentioned above. Algal growth, if any, should be controlled.

3.3.9 RAPID GRAVITY FILTERS

3.3.10 The common problems encountered are:

(a) DefectiveGauges

(b) Rate of flow gauges and loss of head gauges frequently get out of order. The operator

(c) should be conversant with the working of gauges and should be able to handle minor

repairs. Necessary spares should be stocked.

However, even if the rate of filtration gauge is under repair, the filtration rate can be checked

whenever desired by closing the inlet valve and observing the time during which the level of water

in the filter falls by a measured distance.

For knowing the loss of head when the gauges are out of operation, a temporary arrangement

consisting of two glass tubes on each side of a calibrated scale could be provided. One tube is to be

connected to the efficient pipe between filter and controller and the other tube to the filter

structure above the sand. The relative elevation of the water surfaces in these tubes indicates the

prevailing hydraulic gradient or loss of head through the filter.

(d) Inadequate Media on the Filter Bed

The entire bed should be taken out and additional sand mixed to give the required effective size

and uniformity coefficient. Before starting the filter, the sand has to be backwashed to stratify the

bed.

Expansion of sand bed during backwashing should be kept within the limits to avoid carry-over of sand to wash water trough which would lead to appreciable depletion of sand depth over a period of time.Sand depth should never be depleted by more than 10 cm, when the media has to be replenished.

(c) Air Binding

This is caused due to the development of negative head and formation of air bubbles in the filter

sand. This could be overcome by more frequent backwashing during these periods. Provision

should also be made wherever feasible for increasing the depth of water over the bed by about 15

to 30 cm. There are chances of air being released if back-wash is carried out by direct pumping. Air

release valves should be provided on the pumping mains in such cases.

The solution lies in providing adequate depth of water at least 1.5 meters over sand. If air binding

persists, loss of heads may be limited to 1.5 meters instead of normal 2 meters. This will discourage

air binding and will ensure reasonable length of filter runs.

(d) Incrustation of Media

The problem may arise as in the case of water softening with lime soda when sand gets coated with

material that is difficult to remove by normal backwash. The remedy lies in washing the filter

occasionally with sodium hydroxide (10 kg/m2 area of bed) or bleaching power (20 kg/m2 area of

bed).

(e) Cracking of sand Beds.

This occurs mostly when the water is lowered below the surface of the sand. Cracks in a sand bed

under water may also arise due to the cementing of the grains by some material in the applied

water. The vulnerable portion is near the filter walls, since the sand is drawn away from the walls.

The rate of flow increases through such cracks allowing a heavier deposit of solids at these points,

which in turn, intensifies the forces compacting the sand until a dense mass is formed. The degree

of this mass may be limited, creating a dead area, resulting in an unequal distribution of the wash

water. This can be overcome by the use of hand rake or by draining the bed and removing the

clogged sand.

(f) Bumping of Filter Beds.

Sometimes careless and indifferent operation may lead to “bumping” or “lifting” of the filter beds

when switching on the back-wash for a minute to dislodge the sand bed and recommending

filtration without going through the full back-wash cycle is adopted. This practice should be

discouraged as the filtrate quality deteriorates considerably. The old filter beds change by the

department.

(g) Mud balls

These are caused by the general buildup of materials not removed in back-wash. Mud balls

accumulate at or near surface and in course of time clog the entire media.

By proper coagulation and settling of applied water, mud ball formation could be considerably

reduced. Surface washes or surface raking, or shoveling at intervals helps reduce mud ball

formation. Also compressed air scouring during backwash for periods of three minutes, instead of 1

to 2 minutes, effectively decreases mud ball concentration.

(h) Sand Boils

These are caused when disproportionately large discharges of wash water rush towards expending

the sand and displacing the gravel, the situation is encountered mostly due to the poor distribution

of wash-water from the under drain.

(i) Slime Growths

When slime growths are noticed on filters, the bed is cleared in the normal way and the water is

lowered to the level of the sand bed. Then common salt is distributed evenly over the surface of the

sand, using 7 Kg/m2 of filter area, after which the sash water valve is opened until water rises about

15 cm. above the sand level. The water is allowed to remain for 2 hours to dissolve the salt and

then lowered to the bed level to be retained for 24 hours after which it is thoroughly backwashed

before placing into service. If this procedure does not produce effective results, it may be necessary

to replace the media.

(j) Backwash Requirements

The waste water drains carrying filter backwash should be kept free of clogging or sediment. If the

backwash water is led away quickly, there will be no backing up in cater channels or into the filter

bed. Incidentally, it may be worthwhile to consider setting up a plain sedimentation tank to recover

the supernatant from the backwash water. For the small investment, the water recovery could be

appreciable.

The requisite up flow velocity of backwash water should be maintained at the design rate for

proper cleaning of the sand. The practice of backwash at reduced rate for longer periods should be

avoided as it leads to wastage of water and washing becoming ineffective.

Backwashing of filters should not be based on arbitrarily fixed time schedules but the frequency

should be in accordance with the filtrate quality and head lose measurement, Duration should be

dependent upon the turbidity of the wasted water.

3.3.11 SLOW SAND FILTERS

The inlet float valve should be periodically checked with a view to maintain the desired level in the

bed.

The outlet weir arrangement should be checked periodically with a view to ensure the design rate

of filtration. Where there is telescopic arrangement, it should be functioning smoothly and without

drawing in water through the sides. Where manual adjustment is to be done with increasing filter

heads, this should be done at specified intervals.

The filter head indicator should always be kept in working condition. When a filter is clogged, most

of the head loss is restricted to the top layer of sand and if the filter head exceeds 1m, pressures

below atmospheric can occur in sand gravel and in the under drains, leading to air binding or

dissolved air coming out of solution. Occurrence of negative head can be avoided by placing the sill

of the outlet weir in level with the top of the sand bed.

It is most important to avoid rapid fluctuations in filtering rates. Cleaned or resanded filters should

be brought up gradually to the maximum filtering rate and maintained as far as possible at a

constant rate until the head reached the maximum of 1m when the bed should be taken up for

cleaning.

On no account the filter bed be allowed to get reduced by disturbing the top of the sand as this will

impair the bacterial efficiency of the filter.

3.3.12 CHLORINATORS

The chlorine demand of filtered water is to be satisfied and a free chlorine residual maintained to

make it completely safe. Hence the operator should be careful in administering, calculated doses

accurately.

Bubbling the chlorine gas through the filtered water stored in the clear water reservoir by dipping

rubber rubes connected to chlorine cylinder must be avoided. Chlorine application should be done

through a chlorinator only. The chlorinator should be maintained properly. If the unit is out of

order, the same should be repaired quickly and recommissioned.

A complete understanding of the principles of operation of chlorine gas feeders and familiarity with

tests for pinpointing leakages are essential. Low capacity units require frequent cleaning of the Rota

meter and rate setter. Large capacity chlorinators must have vaporizers. The gas piping and feeders

should be completely dismantled every one or two years to clean out accumulated impurities.

3.3.13 CLEAR WATER SUMP & RESERVOIR

Roofing should be periodically checked to ensure that no leakages are there so that pollution can

be prevented. Ventilator outlets should be regularly checked and cleaned to guard against

mosquito breeding and bird droppings. Cleaning of the sump and reservoir should be done

regularly. Level recorder should be kept in working order at all times.

The total capacity of clear water reservoirs should be adequate for storage of treated water,

especially during low supply periods at night when reservoirs become full. Instances are reported,

where water from the filters have backed up into the inspecting galleries, thus reducing the rate of

filtration. The remedy lies in having additional clear water reservoir in the plant, or arrangement for

the final water to be automatically pumped to the balancing reservoirs in the town.

3.3.14 TREATED WATER

The quality of the water before distribution may be controlled by adjusting the calcium carbonate

balance in the water to safeguard against corrosion or excessive scale formation in pipes. The

periodical analysis of the water can also indicate if there is any biological growth in the main and if

any further chlorination is needed to check it. The samples of water collected from several points

should be routinely examined for residual chlorine and other chemical and bacteriological

parameters.

3.3.15 PROBLEMS RELATED TO THE QUALITY & FLOW PATTERN

When flow gets reduced, it may not be desirable to cut out certain units but it is preferable to

operate all the units with reduced flow conditions. In any case, the flow-through condition in the

several units should be periodically studied using appropriate traces. This will help to locate if there

is any short-circuiting so that corrective measures can be adopted.

The flow conditions in open channels should be examined periodically to avoid obstructions and

heading up which will affect the unit process especially the efficiency of the clarification units.

3.4 AERATORS

Aerators are required to be maintained in a clean condition so that maximum water surface and

agitation are provided.

Slime and algae growth on the surface would require cleaning and periodic treatment with copper

sulphate with or without lime to kill growth. The porous plates or rubes used with diffusion

aerators may become partly clogged either from dust in the compressed air or from the collection

of sediment on the outside surfaces. When aerators are shutdown, appropriate cleaning with

detergents or acid and brush should be attempted. Clogging of diffuser plates could be minimized

by (i) maintaining air filters in effective operation, (ii) not over-lubricating air compressors and

blowers, (iii) maintaining air pressure on diffusers, when compressors are shut down.

3.5 MASTER BALANCING RESERVOIRS AND ELEVATED RESERVOIRS

Important aspects to be considered during maintenance are:

(i). Measurement of inflows & outflows: Whenever measuring devices are provided, it should

be seen that discharge at inlets and outlets fairly tally. It should be seen that water level

indicators and recorders are in proper working order.

(ii). Structural Leakages: All structural damages and leakages should be promptly repaired.

(iii). Preventing External Pollution: The manhole opening, ventilating shafts and overflow pipes

should be properly closed and protected with wire gauge from.

(v). A programme for periodical cleaning of the reservoirs at least once in a year should be

undertaken. During such cleaning process there should be facility to by-pass the supply to

distribution system.

(vi). Appropriate safety measures to prevent climbing of unauthorised persons should be

provided. All the railings provided shall be maintained in a safe and firm condition.

external pollution

(iv). General cleanliness in and

around the reservoirs should

be maintained and observed. A

garden around the reservoir

structure may be provided.

3.6 DISTRIBUTION SYSTEM

Important aspects of operation and maintenance of distribution system are detection and

prevention of wastage due to leakage. The object is to control the waste within reasonable limits.

Further in case of intermittent supply, possibility of pollution of empty pipelines cannot be ruled

out. Special inspection of pipelines through marshy or high water table areas, crossings across

waste channels, pipes, etc., and in the vicinity of sewers should be carried out at regular intervals.

Such areas should be identified on plans and bacteriological tests of tap water in such areas need to

be done more frequently and results compared.

A regular programme of leak detection should be undertaken for the entire distribution system

such that each section of the system comes up for leak detection at least once in three years. Leaks

and damages detected should be promptly repaired. The causes of wastage through leakages such

as (i) high pressures in distribution, (ii) corrosive soils, (iii) corrosive water, (iv) inferior quality of

pipes and fittings, (v) age of pipes, (vi) gland packing of valves etc. should also be ascertained. The

repair work should tackle those causes as well.

In a distribution system complaints are received frequently from consumers about

(a) Non-availability of required quantity of water

(b) Low pressure at the supply point

(c) Leakages * wastages through valves & pipelines

(d) Unauthorized connections.

One of the major causes of wastage is unauthorized connections. Procedures for granting

connections need to be streamlined. The officer in charge of operation & maintenance of

distribution system should have powers to inspect any household for water supply to know as from

where that household is taking water.

The entire distribution system could be divided into sub-zones served preferably from one elevated

service reservoir. The maintenance and operation of each zone of distribution system should be

entrusted to at least a junior engineer who should be made the authorized official of the controlling

authority to receive and deal with the complaints. Appropriate registers should be maintained by

him to record the complaints and to note in it the follow-up action till the complaint is redressed. If

the complaint is such that is cannot be dealt with at his level, he should at once refer the matter to

higher authorities under intimation to the complainant. Frequent vigilance checks in the areas

having maximum complaints should be made a part of the duty of the supervisory staff.

It is preferable to have meters provided by the water works controlling agency after charging appropriate monthly rentals to the consumer. This enables effective control over defective meters. Meter repair workshops should be established to attend to repairs of meters promptly. Surface boxes and chamber covers of valves should be frequently inspected and kept in proper condition. Billing for an out of order meter for more than three times consecutively, should be avoided. All attempts should be made to repair/replace out of order meters once these are detected.

Sufficient stock of meters and spares should be available at hand to keep almost every meter in the field in working order.

Comprehensive water rules should be framed to make the maintenance operation most effective.

The consumers should be made aware of difficulties and shortcomings in the maintenance and operation of water supply system. Adequate publicity and public relations are required to be developed for this purpose.

3.7 CONTROL OF QUALITY OF WATER

For a waterworks industry, ensuring an appropriate quality of water to the consumer is its primary responsibility. Quality control is, therefore, required at every step in the water supply process. The physical, chemical and bacteriological tests of water samples need to be carried out at as frequent intervals as required. Reference may be made to Chapter 15 of water supply manual of CPHEEO for more details. The results of these tests should be studied and remedial measures taken promptly as and when required.

These tests are usually needed at:

(i). Source-to determine the raw water quality;

(ii). Treatment Plants-to determine whether the treatment is in conformity with raw-water quality; and

(iii). Distribution system-to determine whether adequate residual chlorine is present in the water supply to consumers.

3.8 TASTE & ODOUR CONTROL

The following measures are applicable in taste and odour control:

(a) Routine examination of samples of raw, settled and filtered water and samples from distribution system for taste &odour;

(b) Periodic Treatment with copper sulphate and by chlorine;

(c) Routine maintenance by flushing distribution system, especially at hydrants served by dead-end mains; and

(d) Maintenance of records of consumers’ complaints and corrective action taken so that it can serve as guide for future.
