INDIA－ 135 －DRAFT OF IMPROVEMENT PLAN

PLAN TITLE :● Proposal for construction of Water Supply System

of North Eastern Regional Institute of Water and Land
Management (NERIWALM) Campus at Tezpur, Assam,
India.

Mr. SUNAR Saligram (India)

BACKGROUND :● The Water Supply System of NERIWALM, Tezpur, Assam,

India was constructed more than 40 years back to meet thedemand of safe drinking water for the residents of thecampus which was approximately 250 in numbers.
● Water demand increased. It will be a MODEL for otheragencies to execute such projects in a bigger way.
● Ground water is the only source of water.
● The under ground water contained heavy concentration ofIron,(7‐12mg/l), Arsenic (3‐5mg/l)
along
with
other
impurities.

－ 137 －PERSONS RESPONSIBLE AND ROLE :● Keyperson :• Assistant Director (Civil) : Responsible for putting up the
proposal to the Review Committee Meeting headed by the
DIRECTOR for allocation of budget for the work after giving
due justification why the work is necessary to be carried out.
• Key Section/Division/Department/Ministry : Construction and
Maintenance Section of NERIWALM.
• Task Force : The Task Force consist of Deputy Director, Asstt.
Director (Civil), Junior Engineer (Civil), Multi Tasking Service andPump Operator and Plumber. The work is usually carriedthrough Contractor having experience in similar nature of works
and with good financial background selected by the Tender
Committee after open bidding.
• Steering Committee, etc : A Construction Committee headed by
the Director and Members drawn from other works
department such as Public Health Engineering Department,
Public Works Department, Accounts Officer and Assistant
Director reviews the quality and progress of the work fromtime to time.

INPUT (Resources required) :• Population of the Campus = 500 persons• Requirement of Safe Drinking water (as per
Bureau of Indian Standard)
1x135x500 = 67500.00 Ltrs or 67.50 M3－ 138 －

Say 68.0 M3/day

MANPOWER
•

•

•

•
•

As the work will be carried out by the Contractor having experience insimilar nature of works the department will more or less be limited toSupervisory in nature such as Quality Assurance and Overall Progress. The
manpower requirement will be as follows.
i) Assistant Director (Civil) : He will be responsible for overall quality andprogress of the work. He has to see that the work in completed within the
stipulated time period and there is no cost over‐run. His responsibility is toreport to the Steering Committee from time to time over the progress of thework vis‐a‐vis Financial Achievement.
ii) Junior Engineer (Civil) : He will be directly responsible at the construction
site to oversee the quality and progress of the work. He will be assisted bySupervisory level staff (preferably ‐ 2 Nos). They all be reporting to theAssistant Director (Civil).
iii) Junior Engineer (Electrical/Mechanical) : For all electrical and mechanicalworks being carried out satisfactorily the JE (Elect/Mech) will be responsible
and in turn report to the AD©.
iv) In addition to the above staffs, the Contractor will have to engage his
Engineers for supervision and carrying out the works as per the given
drawing and schedule.

PLACE, EQUIPMENT, TRAINING @ INFORMATION, ETC• Place : NERIWALM Campus at Dolabari, Tezpur, Assam,
India.
• Equipment : Since the work will be out‐sourced to aContractor, the Contractor will have to arrange for all
the equipments required for carrying out the work. It

will be madeavailable to concerned authority.

－ 139 －ACTIVITY TO BE CARRIED OUT :● Budgetary Provision is made for the work clearly specifying thename of the work.
● Detailed Planning and DPR Preparation of the project along with
Cost Estimate is made by engaging a Government or a Private
Agency (selected through open bidding system).
● Obtaining necessary Administrative and Financial Approval for the
project.
● On obtaining A & F Approval, ONLINE Tenders are to be invitedfrom Bidders having experience in similar type of works (since theamount involved is not so big Global Bidders may not participate,hence limited within India).

EXPECTED OUTCOME :● The expected outcome of the project will directly benefit
500 residents of the NERIWALM Campus by way ofgetting safe drinking water thereby making the residents
free from water borne diseases which is commonly
prevalent in the area. Providing safe water has been the
Government Policy in the form of National Rural Water
Drinking Programme (NRWDP) both by Central as well as
respective State Government.
● If the project is successfully completed and implemented,
it may serve as a MODEL for other agencies to replicate
such type of projects on a bigger scale and for larger
number of the population at the district and block level.
● NERIWALM being a water and land management instituteit can play a lead role in promoting such projects in theeight states of the North Eastern Region of India inparticular and India in general.

INDICATORS FOR VERIFICATION
The following Performance Indicators will be
used for verification.
● Reliability : Better water quality.
● Stability : 7 hours stable water supply.
● Sustainability : 25 years.
● Management : Imposition of water tariff , obtaining subsidy
from the government and consultancy fee to be charged
from interested agencies.

Trend in physical leak

Almost physical leaks sink into the ground and usually
never appear on the ground because of extremely low
distribution pressure(almost zero or pipe has little water.
Under this situation, neither Acoustic bar, Electronic
leak detector nor Correlative leak detector is effective.

Trend in physical leak
Challenge
Leak detection on the pipeline with extremely
low distribution pressure
Matching
Leak detection by a combination of• Pressure control by introducing Block Water Supply,• Visualization of leak which mean to let leak appear on
the ground.
