CHAPTER 1 : REQUIREMENTS OF A MODEL SCHEME FOR FORMULATION BY

BANKS

1.0. GENERAL

This document gives broad guidelines for scheme formulation by banks for

financing of dugwells in hard rock areas. The aspects that are necessary in

scheme formulation are groundwater availability, well design, cost estimates,

cropping pattern, pumpset selection and scheme economics.

2.0. WHY SCHEME FORMULATION IS NECESSARY

It is always desirable to formulate a scheme giving the resource availability,

physical programme and financial aspects over a fixed time frame for

completion of the project. Scheme formulation helps in the following ways.

Planned and sustainable development of groundwater resources.

Proper planning and fixing of targets on area specific basis under a given time

frame.

Ensuring quality of lending, systematic development, assured income to the

beneficiary, assured repayment and recycling of credit.

Quality control of minor irrigation works and equipments for efficient and

economic use.

Systematic monitoring.

Periodical review about achievements and shorfall and taking timely remedialmeasures for successful implementation of the programme.

In view of the above NABARD recommends proper scheme formulation and its

techno-economic appraisal by banks before extending any refinance facilities.

3.0. SCHEME REQUIREMENTS


2/35

Scheme formulation for construction of dugwells in hard rock areas against

bank loans requires both technical and financial details. The important items

that should be included in a scheme for dugwells are indicated below.

3.1. Introduction

This should briefly give the present status of agriculture, irrigation and need for

increasing irrigation for improving the socio-economic conditions of the area,

location of the scheme area, its areal extent and topographical features.

Infrastructure availability like power, roads, etc should be described here.

3.2. Selection of Area

Guidance of the state groundwater department should be taken to select the

project area for minor irrigation development so that adequate groundwater

potential is available for future development and that the area does not come

under over-exploited or critical category. The area selected should be a

compact block / taluka or a watershed with adequate groundwater potential,

easy accessibility by road and adequate outlets for sale of agricultural produce.

This information can be obtained from the state groundwater department and

local district authorities. Brief details about the area selected and the project

benefits should be given in the scheme.

3.3. Soils

The general nature of soils prevailing in the area should be indicated. These

can be classified as sandy, loamy, clayey or black cotton, red soils etc. Soilshave a bearing on irrigation scheduling and depth of irrigation required to meet

the water requirement of crops. Type of soils also helps to select a suitable

cropping pattern and the fertilizer doze.

3.4. Climate and Rainfall


3/35

Rainfall is the main source of recharge to groundwater and groundwater

availability largely depends upon it. It also governs the supplementary irrigaion

requirement of crops. The scheme should therefore, indicate the monsoon and

non-monsoon rainfall as per data recorded by the India MeteorologicalDepartment (IMD). This should also give the minimum and maximum

temperatures during different seasons.

3.5. Hydrogeology

The geological formations in the area, nature and types of aquifers and their

water yielding capacity, average depth to pre-monsoon and post-monsoon

water table and well design suitable for the area should be indicated. Theaquifers in hard rock areas suitable for tapping groundwater are generally

weathered zones, joints, fractures etc. Their availability in depth and areal

extent from the point of view of groundwater development may be indicated in

the scheme. This information is available with the district geologist of the state

groundwater department.

3.6. Groundwater Availability

Before any programme of groundwater development is taken up, it is essential

to ascertain whether adequate potential is available in the blocks covered

under the scheme. The state groundwater department estimates groundwater

resources on a blockwise, taluka wise or watershed wise basis and also keeps a

record of the status of groundwater development at a given period of time. The

categorisation of blocks as dark (critical and over-exploited) , grey (semi-

critical) and white (safe) is made on the basis of stage of groundwater

development expressed as a ratio of draft to utilisable resources,as well as

trend of groundwater table. For over-exploited areas it is greater than 100%,

for dark(critical) areas it is greater than 90%, for grey (semi-critical) areas it isgreater than 70% but less than 90%, and for white (safe) areas it is less than

70%. This information is available with the NABARD regional office and state

groundwater department. Banks can obtain it from them.

Since long term behaviour of water table is a manifestation of the long duration


4/35

availability of groundwater resources, it is necessary to ensure that there is no

declining trend of water table in the area selected for the scheme. Information

on pre-monsoon water table is also necessary to decide the depth of well and

to ensure that the yield of well is not affected due to depletion of water table.

Keeping these in view and for sustainability of the structure and investment,

new well schemes should not be formulated in dark (critical and over-

exploited) areas.

3.7. Groundwater Quality

Groundwater quality in the scheme area as indicated by the state groundwaterdepartment should be given. Its suitability for irrigation may be indicated in

terms of total dissolved solids, sodium adsorption ratio etc.

3.8. Physical Programme

This is desirable to assess the demand for new wells in the area before

formulating the scheme either by interaction with the farmers or the state

agencies like DRDA, SCSTDFC, ITDA or other organisations involved ingroundwater development programme. This facilitates fixing the physical

targets for wells and pumpsets. If the demand is more and targets assessed

are large, the programme could be phased over 2 to 3 years instead of

envisaging entire programme for one year. Such a phasing helps better

monitoring and leaves scope for mid term correction wherever required.

Normally single design of well is uniformly followed in block suitable for the

geological formation. However , if different designs of wells are considered

necessary for differnt geological formations, physical programme should begiven for each type of well design.

3.9. Well Design


5/35

An optimum well design suited to local hydrogeological conditions is important

for success of any minor irrigation scheme. The well diameter should be based

on hydraulic conductivity of the aquifer and the well depth or thickness of the

saturated zone available during the peak demand. At least a 2m of water

column in summer is desirable. Guidance from the state groundwater

department should be taken for this. The recommended well diameter anddepth should be indicated in the scheme. Unit Cost Committee constituted by

regional office of NABARD also recommends average design of well in different

formations. The same should be adopted.

3.10. Well Siting

Normally, the state ground water department provides the map or list of

villages within the block or watershed which are ground water worthy. For

actual siting of well, further assistance/advice could be sought from the local

hydrogeologist of the SGD. However, Annexure I gives the broad guidelines for

financing institutions to enable them to decide the suitability or otherwise of

the site for new wells.

3.11. Spacing

In absence of any groundwater legislation, institutional agencies exercise

technical discipline in the form of spacing between two ground water

structures for proper and efficient development of groundwater resources.

Spacing is determined by aquifer performance tests conducted by the state

groundwater department. However, to avoid over-capitalisation, economic

spacing should also be considered and higher of the two spacings adopted for

financing of minor irrigation works under a scheme. Spacing between two

ground water structures is recommended by the state groundwater

department. Therefore any variation or changes in the spacing stipulated has

to be authenticated by that department.

3.12. Unit Cost

Based on the average design of well in the scheme areas, unit cost of well

should be estimated adopting district schedule of rates and the total financial


6/35

outlay of the scheme should be worked out for the physical programme

envisaged. However, actual cost of well may vary from location to location and

loan should be sanctioned for actual cost of well. It is important to avoid under

financing of well that may render the investment infructuous.

3.13. Pumpset

Proper selection of pumpset in conformity with BIS 10804-1994 is important to

achieve maximum output at minimum capital and operation cost. The scheme

should give the type of pumpset (diesel / electric), requirement of horse power

of the pumpset, size of suction / delivery pipes for the required discharge and

operating head as per average agronomical practices and hydrogeological

conditions in the scheme area. If site conditions require construction of a pit or

provision of a platform in the well steining for placement of the pumpset at

different levels , these should also be given in the scheme and its cost

provided for. (Please refer to NABARD publication on Selection and Financing of

Agricultural Pumpsets).

3.14. Economics

The economics of investment should be given in detail to justify the loan. Thescheme should also give details about subsidies, repayment schedule, rate of

interest etc.

3.15. Check list

A checklist should always accompany the proposal. This would help to check at

a glance whether or not the details or essential items of scheme formulations

have been incorporated. A check list is given in Annexure - II.

CHAPTER II : MODEL FOR A SCHEME OF DUGWELLS IN HARD ROCK AREAS

1.0. INTRODUCTION


7/35

Formulation of a scheme is explained in the subsequent paragraphs taking the

case of a model block.The scheme aims to provide financial assistance for

construction of 150 dugwells with pumpsets to individual farmers for irrigation

development through groundwater sources. These wells would mostly benefitsmall and marginal farmers in the area where at present irrigation facilities

either by surface or groundwater sources are inadequate. Dugwells are the

most suitable stuctures for the hydrogeological conditions obtaining in the area

and would be constucted by local contractors using conventional methods.

Infrastructural facilities like road, powerlines and extension services by the

state government are available for successful implementation of the minor

irrigation programme.

2.0. SELECTION OF SCHEME AREA

The block in the district has been selected to formulate model scheme for

minor irrigation development. The block has a geographical area of 17,500 ha

of which 14,000 ha are cultivable. It is located 15 km from the district

headquarter town. It has an undulating topography and the elevation ranges

from 300 m to 400 m above mean sea level . A canal of 9 km length with

wetted perimeter of 2.5 m flows for about 90 days during the non-monsoon

period. An area of 9200 ha is presently irrigated from canal and 1157 existing

irrigation wells.

3.0. SOILS

Soils in the scheme area are of black cotton type and suitable for growing

jowar, wheat, vegetables and cash crops like sugarcane and groundnut.

4.0. CLIMATE AND RAINFALL

The scheme area in general has a sub-humid to tropical climate. The monsoon

season extends from mid-June to September end. About 90% of the total

annual rainfall of 750 mm occurs during this period only. The average

temperature and humidity are 27o C and 65% respectively. The fair weather


8/35

season extends from mid October to February during which a winter rainfall of

about 60 mm is recorded. The temperature during the months of December

and January comes down to about 18oC. The hot weather conditions last from

March to mid June and are characterised by high evaporation with temperature

going upto 36oC. The rainfall pattern varies from year to year and on an

average there is a dry spell once in 5 years. As per IMD records, the normalannual rainfall in the area is 760 mm.

5.0. HYDROGEOLOGY

The area comprises of basaltic rocks with an aggregate thickness of over 100

m. The individual basaltic lava flows vary in thickness from 10 to 15 m and are

made up of alternating massive and vesicular units. The massive units are hard

and compact but highly weathered upto a depth of 10 m and are jointed and

fractured upto a depth of about 50 m. Vesicular units are generally soft and

make upto 30% of the total thickness of individual lava flows. These individual

flows are sometimes separated by beds of red clays. Groundwater in the

scheme area occurs under water table conditions. The weathered and jointed

zones in massive units and vesicular zones are the main water bearing

formations. These aquifers are inter-connected forming a type of multi-layered

system but show lateral and vertical variations due to heterogenity of aquifers

which governs the well yield. Hydrogeologically, aquifers in the scheme area

are good and are suitable for construction of dugwells. Their hydraulic

conductivity as estimated by the state groundwater department varies from 8to 12 m/day. Dugwells in the area vary in diameter from 4 to 6 m and in depth

from 15 to 20 m. These wells give a discharge of 4 to 6 litres per second for a

pumping period of 4 to 6 hours per day for a draw down of 2 to 3 meters. The

well recoups by next day.

6.0. GROUNDWATER AVAILABILITY

6.1. Recharge

The state groundwater department (SGD) has estimated the available annual

recharge by water table fluctuation and specific yield method. This includes

recharge from monsoon rainfall and from supplementary sources like canals

and tanks, re-cycled irrigation water, non-monsoon rainfall etc. The available


9/35

recharge as estimated by SGD in the block is given below.

Total Annual Groundwater Recharge(ham) 4200

Net annual groundwater availability (ham) 3780.

After allowing for the existing and projected demand for drinking water and

industrial use, the balance groundwater recharge available for irrigation is

estimated at 3570 ham.

6.2. Draft

Irrigation by electric and diesel operated pumpsets is the common method of

groundwater extraction in the area. The average draft of a dugwell with

pumpset is about 1.2 ham/year. Thus the total annual groundwater draft is

about 1326 ham and is given in Table 1 below.

6.3. Water Balance

Net annual Groundwater availability for future irrigation development use is

2244 ham.

6.4. Stage of Groundwater Development

The stage of groundwater development is defined by ratio of existing gross

annual groundwater draft to net annual groundwater availability and expressedas percentage. From the groundwater estimates by the state groundwater

department, the stage of groundwater development in the block is 41%.

Further the long term behaviour of water levels in the observation wells as

recorded by the state groundwater department, does not show any progressive

decline during past 10 years. Accordingly, the block is categorised as white

(safe) and new well programme in the block is feasible.

7.0. PHYSICAL PROGRAMME

A programme of 150 dugwells with pumpsets is proposed under the scheme.

The unit gross draft of a dugwell is taken as 1.2 ham per year. The gross draft

works out to be 180 ham, against a water balance of 2244 ham. Thus the

proposed programme in the block is feasible. The stage of groundwater

development after financing the proposed programme would be within 70%

and the block would remain in the white (safe) category.

8.0. SPACING

The spacing between two dug wells as based on aquifer performance test

conducted by the SGD works out to be 120 m. However, spacing on economic

considerations has also been examined. A dugwell with pumpset can irrigate

an area of about 2 ha and thus, on economic considerations, the spacing would


12/35

be 150 m. Thus, spacing between two wells would be kept at 150 m.

9.0. GROUNDWATER QUALITY

As per report of the state groundwater department, groundwater in the block

shows low values of total dissolved solids (TDS less than 700 ppm) with Sodium

Adsorption Ratio (SAR) less than 10. The water is therefore, suitable for

irrigation purposes.

10.0. WELL DESIGN

In the scheme area a saturated thickness of about 6 m is available in a well

depth of 15 m. The water table aquifers in the weathered and jointed zones,

vesicular units have good hydraulic conductivity and are capable of yielding

about 5 to 6 lps. The state groundwater department has recommended a well

of 5m diameter and 15m depth in the scheme area and the same is adopted.

Predictably, within this depth, atleast 2 m of water column would be available

in the wells during summer season.

11.0. CROPPING PATTERN AND COMMAND AREA

The crops grown in the scheme area under irrigated conditions are jowar,

wheat, vegetables, groundnut and sugarcane. The command area of a dugwell

varies from 1.5 to 2 ha. The well discharge can meet the crop water

requirement for such a farm model. The cropping pattern and water

requirement for a 1.6 ha farm model are given below in Table 2.

12.0. Discharge Required

The discharge required has been calculated from the following formula:

Q = 28 AI

Rt

where, A = Crop area in ha


17/35

I = Depth of irrigation in cm

R = Rotation period in days

t = Working hours per day

Q = Required discharge in lps

The discharge required during the different crop seasons is calculated below:

KHARIF Q = 28 ( 0.4x5 + 0.8x7.5 + 0.4x7.5 )

20x4 30x4 15x4

= 3.50 lps

RABI Q = 28 ( 0.8x7.5 + 0.4x7.5 + 0.4x8.75 )

30x4 20x4 12x4

= 4.49 say 4.5 lps

SUMMER Q = 28 ( 0.4x7.5 + 0.4x10 )

12x4 10x4


18/35

= 4.55 lps

Considering water losses at 20% (irrigation efficiency at 80%) the required

discharge would be:

Kharif = 4.4 lps

Rabi = 5.6 lps

Summer = 5.7 lps

The discharge required during the Rabi and Summer season is 5.6 lps and 5.7

lps respectively, say 6 lps. This can be met from the design of well proposed

under the scheme. A discharge of 6 lps is therefore taken for selection of

pumpset.

13.0. PUMPSET SELECTION

A centrifugal pumpset is suitable for installation on dugwells. This type of

pumpset, both electric and diesel are also commonly used in the scheme area.

The pumpset has been selected as per IS-10804-1994 keeping in view the

discharge and the total pumping head and the pump/motor efficiencies as

observed from the relevant tables and curves.

13.1. Discharge Required

The discharge required is 6 lps for a daily pumping period of 4 hrs.

13.2. Total Pumping Head


19/35

The total pumping head to meet peak demand (5.7 lps) in summer season is

likely to be 15.4 m (apprx) with 65 mm dia GI pipe. This includes total static

head, friction losses in pipes, allied fittings, foot valve and offset pipe as per

norms on suction and delivery side. The required HP of the pumpset underthese conditions works out to be 3.0. This includes 10% additional input to

nominal pump input to take care of tolerance on pump efficiency and variation

in duty. Accordingly, pumpsets of 3 HP are considered under the scheme.

13.3. Pumpset Specifications

The specifications of the electric pumpset selected for the scheme area are as

below:

a) Centrifugal Pump

Total Head (H) = 16.3 m

Discharge(Q) = 6 lps

Efficiency (n) = 54%

b) Piping System

Suction/Delivery pipes = 65 mm

Foot valve = 65 mm

( K = 0.8 m)


20/35

Straight length = 17 m

of 65 mm GI pipe

Long radius bend (65 mm) = 2 Nos.

c) HP of pumpset (electric/diesel) = 3

The complete pumping system would be installed as per IS 10804 - (1994).

14.0. COST ESTIMATE

The cost estimate for the well with suggested design is made on the basis of

prevalent schedule of rates. The unit cost works out to Rs.37000/-. The cost

estimate of the dugwell in the scheme area is given below in Table 3.

15.0. TOTAL Financial Outlay

The unit cost of a dugwell with 3 HP pumpset is Rs.59000 (Rs.37000 + Rs.7000 + Rs.15000). The financial outlay of the scheme for 150 dugwells with

pumpsets is Rs.88.50 lakhs.

16.0. Economics

The scheme economics is given in Annexures III and IV. It is seen therefrom

that the net incremental income is Rs.26,870 per year and the IRR works out to

be 49%. Thus, the scheme is considered economically viable.

17.0. INFRASTRUCTURAL FACILITIES

Adequate extension services are available in the scheme area. The

beneficiaries having irrigation facilities have adopted modern cultivation

practices. A good net work of low tension/high tension power lines exist and

energisation of pumpsets can be expected without any delay. A sugar factoryis located in the nearby block and marketing of sugarcane produce will not be

a problem. A market yard exists within 3 km for marketing the agricultural

produce and there are good all weather roads for transport of agricultural

produce.

18.0. Supervision and Technical Guidance

The technical officer of the sponsoring bank would look after the supervisionand implementation of the proposal and also extend technical guidance

wherever necessary.

19.0. Lending Norms


27/35

Majority of beneficiaries (70%) are in the small and marginal farmers category.

20.0. Repayment Period

For small and marginal farmers, the loan repayment period of a dugwell would

be 11 years excluding a gestation/grace period of 23 months and for pumpset

9 years. The beneficiary may, if he so desires, repay the loan instalment with

interest earlier than the stipulated period. For other farmers, the loan

repayment period would be 9 years.

21.0. Rate of Interest

The present (2003-04) refinance rate to the financing bank for minor irrigation

investments is 5.50% for NE region including Sikkim, A&N Island, whereas for

other regions, it is 5.50% and 6.25% respectively for loansizes upto Rs.

50.000/- and above Rs. 50,000/-. The minimum down payment would be 5%.

ANNEXURE- I

Guidelines for Selection of Well Sites

Broad guidelines for financing institutions to enable them to decide upon the

suitability (or non-suitability) of the site for new wells are given below :

Guidelines for Location of Wells :

Areas included between two nalas near the confluence having a soil thickness

of over 30 cm and weathered mantle of over 5 meters (A weathered mantle

comprises of morum, loose sandy material, etc.)


28/35

2. Alluvial flats close to river or streams.

3. Depressions in landscape having more than 30 cm of soil cover and 5

meters depth of weathered mantle.

4. On the banks of nalas towards the high ground provided the banks are

not clayey.

5. Zone of luxuriant, vegetation with leafy plants.

6. Old courses of rivers and streams which are represented by presence ofsands and gravels.

7. Near the sharp bends of the streams or rivers.

8. Damp or moist areas.

Wells should not be located in :

1. Areas where hard rocks are exposed.

2. Areas adjoining ridges and spurs and within about 50 meters of them.

3. Areas with a soil cover less than 30 cm.

4. Areas with a weathered mantle less than 5 meters in depth.

The thinkness of the weathered mantle can be roughly determined by looking

at existing wells in the nearby area. If no wells exist, the exposures in nalla


29/35

beds will give an indication of the depth of weathering.

The above guidelines, if rigidly followed, would minimise the chances of failure

of wells and ensure location of wells in the groundwater worthy areas.
