From the Desk of President

Friends,

Today we get the best qualities of pipes and the jointing systems available in the world. This has

minimized risk of leakages from pipes.

We may do a very good design of water supply as well as drainage.

We also need to support the pipes properly at regular distance to avoid sagging of pipes resulting in silt

deposition in pipes and finally blockages.

My concern is about the plumbing of modern buildings where a plumbing contractor has to manage all

his services in the minimum space provided. In some redevelopment buildings there is no open space

available to lay Under Ground sewers or water supply distr ibution.

The solution is to run all the pipes suspended from the ceiling in one of the basements.

Generally it observed that the pipes are fixed in the

manner shown on right side of the sketch. Which is

wrong and may lead to pin -hole punctures after

some years due to vibration in the pipe. Right way of

bracketing pipes is as shown on left hand side . The

pipe should be fully supported at the bottom half OD

Also the distance between 2 split brackets should be

different as per the size and material of pipe, e.g.

Distance between brackets for 150mm pipe and

15mm pipe cannot be same.

Spacing of brackets for different diameters and

material is given in the following table.




SPACING CHART FOR CPVC PIPES

SPACING CHART FOR UPVC ASTM PIPES

SPACING CHART FOR UPVC SWR PIPES




I have tried to give details of spacing for commonly used pipes. Spacing of brackets/ clamps for any special pipes can be had from the manufacturer of that particular pipes

Hope this will prove informative.

Micro-Management & Rainwater Harvesting

1. Introduction: "Water, food, clothing, and shelter" are the basic needs of every human being.

Since ancient times the early settlements throughout the world have been made near springs,

lakes and rivers, where plenty of potable and natural water could be available. Digging of wells

was the exclusive method of obtaining a water supply by the settlers in the other areas. With

increase in population the limited supplies from wells or springs were found to be quite

inadequate, which necessitated storage of water in the neighbourhood of the town and conveying

it as per needs. The conveying was mainly done through aqueducts and pipes run under gravity.

Storing of water in the underground cisterns was done in olden days in Jerusalem and Greece.

About 5000 reservoirs for irrigation purpose were found by the English people in the Madras

State, India, at the time of their occupation. The construction of these reservoirs involved about 16

kilometres of earth embankment.

The main two source of water supply are surface water and ground water. Surface water is a

mixture of surface runoff and rejected ground water and includes rivers, springs and lakes etc. In

most instances the surface water is subject to pollution and contamination and must be treated

before use for drinking purpose. Rain water is derived from the vapours rising from the seas,

rivers, lakes, etc. forming into clouds and then condensing as rain, hail or snow. On reaching the

earth, part of it is held by the top soil to feed vegetation but percolates through the earth, and it is

from these two source that we obtain our water supplies. Rain water being distilled water is

supposed to be pure and soft. But rain absorbs gases (generally carbon dioxide), bacteria, and

solid impurities such as dust particles and soot, while falling through the atmosphere and its purity

on reaching the earth depends upon the cleanliness of the air through which it falls.




2. Water Audit of India: India has been blessed with 113 rivers flowing up to approximately,

45,000 kilometres in length, consisting of 14 major, 44 medium and 55 minor rivers. Three of the

major rivers are International and the remaining 11 are national and together they contribute to

approximately 80 percent of the Indian water.

The average annual rainfall of India, distributed over the entire Indian geographical area, comes

to about 1.2 meters, (against 0.86 by the entire world.), as its total geographical area is 328

Million hectares, and total rainfall is 400 Mha-m, including 10 Mha-m. Of snow fall. It has also

been estimated that the moisture present in the sub-continent (India) is about 770 Mha-m during

monsoons and 340 Mha-m during the rest of the year. The total precipitation of 400 Mha-m, as

against the total moisture of 1110 Mha-m proves that only about 30 to 35 percent of moisture

present in the atmosphere comes back as rain fall over the sub-continent. Out 400 Mohan-m of

total precipitation, it has been estimated that 30% appears true run-off, 20% evaporation, base

flow about 11%, groundwater about 12% and the balance in soil moisture.

3. Water Works Practice: The main aim of implementing a water supply scheme is to provide

pure and wholesome water- free from bacteria- to the community for drinking and other household

purposes during all seasons of the year. The main features of a rural water supply scheme are -

a. Head Works - Construction of jack well, infiltration gallery, inspection well, pump house and

installation of pumps.

b. Rising or Gravity Main - Depending upon the location and level of the source and reservoir.

c. Ground or Elevated Service reservoir - to store water for distribution purpose during non-

pumping hours.

d. Distribution System - Consisting of network of pipes and valves, stand post etc.

e. Treatment Works - Provided tailor process depending upon the type of impurities present in

the drinking water before it is let in the distribution system.

4. State Welfare Measures: In the pre-independence era, the Government through its Well

Sinking Department used to dig wells up to 10.0 to 15.0 metres deep, in the villages. These wells

were lined with bricks, stones, or lime mortar from inside to protect the peripheral loose material.

The number of wells provided in each village would vary depending upon the size of village

(population and area)




Separate wells were provided for lower caste people. After independence the government moved

very slowly in the matter of providing water to rural masses. Only in the Third Five Year Plan

(1961 -1966), the central government laid a considerable stress on the need of carrying out

surveys in the States with a view of making correct assessment of the existing state of rural water

supply and for preparing a concrete programme. Rural Water Supply schemes were taken up in

the State under the programmes of Community development, local development works, and

welfare of backward class, etc. The central government gave priority to rural water supply

schemes. It also decided to take up rural regional water supply schemes so that the huge cost of

source development and piping be shared and benefited to larger population. Over the years, lot

of schemes have come up but unfortunately have failed because of lack of proper source.

5. Author's Experience: The second author had an opportunity to work in the State PHE Dept.

(now MJP) during 1971-76. He was supervising on the following three water supply projects

during his 2 years of posting at works site.

a. Mulaj Rural Water Supply Scheme: A village with about 2000 population is famous for betel

leaf production in the district. The village proudly boasts giving 3 MLA's for 20 long years,

naturally this was the first scheme in the Taluka. The scheme had all its usual features of a rural

water supply scheme with a local stream as a source. The work had finished and the project was

handed over but it was noticed that the distribution system was faulty. Non-pressure r.c.c. pipes

were laid at shallower depths, in the distribution system, as against pressure pipes at reasonable

depths to be provided as per item in tender.. Leakages started to appear at different places on

commissioning the project. The entire distribution was replaced with A. C. Pipes laid at

appropriate depth. The yield from the jack well was not adequate and hence provision of

infiltration gallery and inspection well were made in the revised estimate to augment the yield.

The matter was raised in the Legislative Assembly and had hit the newspaper headlines several

times.

b. Murum Urban Water Supply Scheme: A municipal council with a population of about 12,000

had all the features of a rural water supply scheme. The source of the scheme was a local river,

Benitura, where a jack well was constructed. The project was complete in all respect except

installation pumps, commissioning of pumps, and rcc reservoir etc. The completion work was

done at snail's pace and the project was handed over to the Municipal Council without a drop of

water in the jack well.

c. Killari Rural Water Supply Scheme: The source of this scheme was a local river Terana, a

tributary of Manjra. It was one of the successful source to cater to the needs of the people. The

construction of Jack well, Infiltration gallery, Inspection well , rising main, RCC reservoir up to 1st

stage with raft foundation and distribution system were completed under author's supervision

during 1.5 years. (This reservoir withstood the shock of killer earthquake that hit the region

on 30-09-1993.). Initially the locals were not really happy with the scheme as they were thinking it

is a wasteful expenditure of the Government. But soon they realized that it has come as a boon to

them. The local population had to depend upon this source for all their needs, due to famine in

the area. Apart from this even the local Sugar factory had to draw water from this source for its

construction and drinking purposes, by making temporary arrangements.




d. Inferences : When the author look back to his 5 years of career in state PHE Deptt., 2 years

on site and 3 years in Circle Office, he really feels proud of his fellow engineers who trudge to

rural areas and execute the works under all odd conditions. But unfortunately their efforts are not

lauded as they fail to supply water during crisis time due to inadequate and improper selection of

source. The source must yield a minimum quantum of water during dry season of May and June.

We have made an attempt to give a thought on the Rain Water Harvesting proposal and take up

the pilot schemes and implement it throughout the State, if found suitable.

6. Micro-Management & Rain Water Harvesting: Considering the huge deficiency in water

supply projects people have been suffering over the last several years. Therefore a new

approach in micro-management needs to be thought of. The collection and storage of rain from

run-off areas such as roofs and other surfaces has been practiced by Man since ancient times. It

is still used in many parts of the world and is particularly useful where water supply is inadequate.

By careful design it is possible for a family to live for a year in areas with rain fall as little as 100

mm per year. Many observations made in Zimbawe, Botswana and Israel show that between 80

to 85 per cent of all measurable rain can be collected and stored from outside catchment areas.

This includes light drizzles and dew condensation which can occur in many parts of the country

during the drier months.

The run-off from a catchment area can worked out by the simple formula, Q = C x I x A,,

Where, Q = discharge in cum, C =co-efficient of run-off, I =Total rainfall per annum, m and A =

Catchment area, sqm.

The co-efficient of run-off depends upon the shape, size, soil conditions, temperature, and geological

conditions of the area of the catchment. However on the basis of average annual rainfall in the area

the co-efficient can be assumed e.g. Dry tracts with annual rainfall--350 to 750mm---15 to 20 percent,

Intermediate Zones rain---750 to 1500 mm ---20 to 30, Higher Zone with rainfall above---1500 mm ---

30 to 55, and Roof and Paved areas---80 to 90

As an example, if the rainfall is 635 mm per year the run-off from a suitable catchment

area will be about 500 mm, and an area covering 1 hectare may yield 50,00,000 litres of water per

year- enough for 500 heads of cattle for six months. One millimetre of rain falling on one sqm of

area will yield approximately one litre of water. The requirement of solely domestic purpose may

be 15 to 20 litres per head per day. Considering a family size of 5 persons, the daily requirement

would be 100 litres. If we assume that the longest period without rain would be 6 months, the volume

of water required to last through the dry season would be 180 x 10 = 18,000 litres.

All harvester surfaces, being exposed to atmosphere throughout the year, are subject to

contamination by dust, insects, and birds and those at ground level are liable to be fenced and kept

clean .The first flush of the new rains should be run to waste. Storage tanks may be built below or

above ground. The tanks should be fully enclosed to prevent evaporation. All apertures should be

screened to prevent the access of mosquitoes , rodents, lizards, and other life. Sometimes water is

passed through a sand filter before it is consumed for drinking.




7. Artificial Harvesters: If water is required where there is no roof or rocky outcrop suitable for

collection, the construction of an impervious surface can be undertaken on the ground itself.

Reinforced concrete can be used to make surface i.e. chicken wire reinforcing should be used to

prevent cracking of the floor. An alternative technique is to lay a large piece of plastic sheeting in a

hallowed out and leveled area of ground. A layer of sand is laid over the bottom of the excavated area

and raked flat. The sheet of plastic is laid out over the layer of sand and the edges raised up against

the side walls of the excavation. A drainage system is now laid in the form of a slotted PVC pipes

which drains away into the reservoir used for storage. Finally a layer of gravel or very coarse washed

river sand is laid on the bed. The edges of the area should be raised with a rim of concrete work. No

part of the plastic sheet should be exposed to sun or it will perish within a year. The area should be

fenced off to prevent access to animals. A figure below illustrates water harvesting in a homestead.

The construction of reservoir is the biggest cost. It may be either in stone masonry or r.c.c. and

provide either below or above ground.

8. Conclusion:

a. The schemes have been successfully implemented in Tamilnadu, Gujrat, and parts of Madhya

Pradesh and Government of Maharashtra.

b. The efforts of state and central government agencies of dreaming to provide adequate water

supply to rural people have failed miserably due to non-availability of reliable source of water.

It is necessary to store water in lakes, ponds, and artificial ditches and improve the ground

water table.

c. It is also necessary to prepare a grid of national water and connect the rivers .All irrigation

projects must be taken up for completion immediately. The Projects like Telagu Ganga

Project and Narmada Project must be completed on priority. Similar projects should be

thought of and implemented to overcome the problem of drinking water in India.

BRIEF HISTORY OF ANNUAL DAY & FOUNDATION DAY

Celebrating Annual Day was started from the year 1984 after

Foundation Day. Previously we were Celebrating Foundation Day along with

Annual Day like get together jointly from year 1976 to 1980 under late Shri.

Kale as president Annual Day on Big scale was celebrated in year 1979-80

which was having program of musical orchestra. Melody makers (Poona) on

the same day we had felicitated some old senior members with shawl &

Shrifal and given a Certificate from our Association.

R.S. Parikh

One of the first member to be felicitated was my father Shri. Shantilal C. Parikh, At that

time the very first souvenir, members list & life membership Certificates were given on that

occasion no dinner or cocktail was given.

The present format of Celebration of Annual Day was started from year 1984 85

which was held at Hotel Diplomat , Colaba and the same was sponsored by M/s. Sai Jagdish

Valve Co., Jalandhar from that year we started Celebrating Annual Day's Get together along with

AGM on the same day. We are getting sponsorship for celebrating this event every year up to

now.

The very first Satyanarayan Puja carried out to commemorate Foundation day

was in the year 1996. Mr. & Mrs. G.N. Ganla performed the Puja and since then we are having

Satyanarayan Puja every year on Foundation Day. We started giving Award momento to our

members / organization institute students etc by the fund received from our members or in

memory of our senior members or their relative. The following awards were instituted-

1) Late Shri. D.G. Kale Award

2) Shri. S.P. Chopra Award

3) Shri. P.K. Raman Award

4) Late Shri. B.G. Gandhi Award

5) M/s. American Standard Award
