EXECUTIVE SUMMARY

PROJECT

The Department of Public Health Engineering(DPHE) is responsible for supplying potable water

to the rural people of Bangladesh.United Nations Children's Fund(UNICEF)has been assisting

DPHE in its endeavor since 1972. Since 1970's and particularly after 1980's the growth pf

minor irrigation was rapid. Due to large scale abstraction of groundwater for irrigation use, the

groundwater levels have lowered in many areas rendering many tubewells fitted with suction

mode hand pumps inoperable particularly during dry months. To sustain the continued water

supply to the rural people installation of Tara (deepset) pumps are required.

The Engineering and Planning Consultants Ltd. in association with M/s. Mott MacDonald have

been assigned by DPHE/UNICEF to identify the areas for phasewise requirement and

installation of Tara pumps. The work started from 20th December, 1993 and ended on 20th

June, 1994.

The areas under study covered all of Bangladesh excepting the coastal areas, greater

Chittagong, Chittagong Hill Tracts and part of greater Sylhet district. The main reason for

exclusion of these areas is inadequate database.The total number of studied thanas are 349

and listed in Table 1.2.

A wide range of models and programs were used, and developed as required to form an

integrated package for predicting the impact of irrigated development on rural water supplies.

According to the local hydrogeological conditions, these models can be equated with single

or multiple layered aquifer conditions as applicable according to the aquifer conditions.AII the

areas are modelled as single cell models, where the basic grid cell is equivalent to a thana.

Both the single and multiple layer aquifer conditions are modelled through the integration of

a suite of new and existing models and data sets. The elements of the modelling approaches

are :

Definition of potential recharge as the ultimate limit to groundwater development

Definition of depth-storage profiles to determine the relationship between the net

groundwater abstraction and depth to water

Analysis of historical minor irrigation data to predict future growth of irrigation by mode

Study to Forecast Declining Groundwater Level in Bangladesh

\

• • • • o i .

Compilation and analysis of historical irrigation statistics and demographic data in order

to estimate groundwater abstraction

Compilation of groundwater level data to define the existing conditions for hand pump

tubewell operation

Calibration of depth-storage curves against historical water level and abstraction data

Prediction of future water levels

For single layer aquifer conditions, the following steps have been defined for prediction of

future water levels (and are further illustrated by Figures 1.1 to 1.3).

In total 349 thanas of Bangladesh were studied and the thanawise final output of the model

results are given as Data Report in four volumes. A sample of the output of Adamdighi thana

is given in Figure 1.4.

The final calibration of Adamdighi thana in Bogra district is given as a case study. Hydrographs

and model output for Adamdighi are shown in Figure 1.5 to 1.9.

Figure 1.7 shows the basic depth-storage calibration. The water level and abstraction cross-

plot is calibrated with the medium depth-storage plot. No increase or decrease of the specific

yield values were required. The abstraction in 1991 exceeded the Master Plan Organisation's

(MPO) estimated usable recharge but according to figures 1.5 and 1.6 the recharge capacity

of the aquifer has not been exceeded and justifies a modest increase in the usable recharge

factor of 20 percent. Figure 1.8 shows the rapid growth of irrigation since irrigation shallow

tubewells became easily available and that there is infact, little irrigable land left for further

development. Based on this rate of growth the figure 1.9 shows the net abstraction and the

resultant water levels would be expected in 1995, and it will remain static till full

development. Please note that in cases where irrigation growth stops in the near future due

to exhaustion of recharge, subsequently the irrigated areas will decrease due to increase in

demand of drinking water supply for increased population.

•The study results predicted the hand pump tubewells requirement for the years 1995, 2000,

2010 and in full development of the resources and is given in Table 1.2,

Hydrogeological parameters and use of land and water resources wer,e worked out and areshown in Table 1.3.

Study to Forecast Declining Groundwater Level in Bangladesh

CONCLUSION AND RECOMMENDATION

a) UNICEF may prepare a schedule for phasewise replacement of No. 6 pumpsby Tara pumps in the predicted areas as "Marginal Tara areas" and "Taraareas" as shown in Table 1.2. A summary is tabular form indicated thephasewise coverage of thanas by hand tubewell requirements is shown inTable 1.1 and another summary predicting the population to be served bythe different hand pump system is shown in Table 1.1 A.

b) In order to improve the studies more accurate monitoring of groundwaterdevelopment will be needed in terms of nationwide network of groundwaterlevels, numbers of operating units and actual abstraction.

c) The studies have indicated that groundwater development may beconstrained in areas of the eastern hills of Sylhet and the Sylhet basin dueto difficult aquifer conditions and use of LLP for surface water availability.

d) Uncertainly over the privatization of DTWs specially in time. With theincrease of population the irrigation demand may be higher and to meet upthe demand the privatization of DTW will come up.

e) In the study the deep percolation (DP) values of the MPO DP3 (mediumvalue) is used. In some cases the abstraction is far below the DP3 conditionbut in areas like Bogra district for higher abstraction, DP4 (medium high)values were considered. So, care should be taken to use the DP values.

f) Groundwater recharge conditions in Bangladesh is advantageous withrainfall and with much of the country flooded during the monsoon.

g) In the terms of reference there is no provision for hardware or softwarehandover, training or production support. Some training is always necessaryand there may be some provision for pertaining training to the users.Moreover, we believe the programs which we have developed for thisproject have an application in DPHE and UNICEF that go beyond the specificobjectives of this project.
