WATER  RESOURCES DEPARTMENT

DRAFT ANNUAL  PLAN  PROPOSALS  2009-10

IRRIGATION  &  FLOOD CONTROL

 

Introduction:

The geographical area of the State of Goa is 3,702 Sq. Kms and it is endowed with an annual rainfall of about 3,500 mm during the four months’ period from June to September as well as a rolling topography, thus, paving the way for providing storage dams to meet the domestic, industrial, irrigation and tourism water supply needs of the State. The river basins in Goa have geologically been divided into 4 distinct sub-regions, broadly going from West to East. (i) Coastal plains on the West (ii) Vast plains adjoining the coastal plains (iii) Low hills and table lands (iv) High Western Ghats. Short lengths of rivers, deep marine ingress, steep slopes in the Western Ghats and reserved forests pose constraints for large storage structures. Due to thin soil cover and highly rugged configuration of the topography, heavy rainfall leads to high run off rendering the period from November to May dry. In order to meet the immediate need for drinking water, and considering the geological conditions of the State, the State has resorted to interlinking of rivers within the basin and from one river basin to other river basins also by constructing a series of bandharas which are eco-friendly storage structures constructed across the rivers for post monsoon water harvesting and ground water recharge.

The Water Resources Department constructs various storage structures for irrigation through major and medium irrigation projects, takes up water distribution works under Command Area Development Authority (CADA) and minor irrigation works such as storage works, diversion structures, wells, lift irrigation schemes, water resources development programme and similar works under Western Ghats Development Programme (WGDP) i.e. Hill Area Development in Sattari, Sanguem and Canacona talukas.

The water resources of the territory have been assessed at 8,570 M. m3 by the Central Water Commission (CWC). However, due to topographical, geological and other constraints the level of utilization of resources for irrigation is expected to be 1,465 M. m3 (1125 M. m3 surface + 340 M. m3 ground water). Thus 89,660 Ha of agricultural area can be brought under irrigation as indicated in the master plans of the State Water Resources, out of which 82,260 Ha will be by surface water and 7,400 Ha by ground water.

 

To help better utilization of the irrigation potential created, under the Command Area Development Authority, the State has prepared Participatory Irrigation Management (PIM) Programme, and as per the policy of the Government, Water Users’ Associations have been formed and the water distribution system has been handed over to them for maintenance, collection of water charges and for better utilization of the irrigation potential to achieve self sustainability and make agricultural activity self-sustainable and economically viable.

Various works are taken up under Flood control, Anti-sea Erosion and Drainage schemes to prevent/minimize damages and losses due to floods and sea waves. During September 2007, the towns of Sanquelim and Bicholim had to face flooding problem due to heavy precipitation, thereby damaging commercial establishments, households and agricultural properties. The State has taken immediate steps to constitute a High Level Committee to decide protective measures and give immediate relief to the affected people.

Suitable schemes have been formulated and the proposal has been submitted to Government of India to avail assistance under flood control and river management works under Flood Management Programme (2007-12) in the form of grants to the extent of 75% of the cost.

In order to overcome the problem of erosion of beaches the State has participated in Government of India’s Programme implemented through Ministry of Water Resources Preparation of Project Technical Assistance (PPTA) which also proposes availing assistance from Asian Development Banks (ADB) for Sustainable Coastal Protection and Management Programme. 

A Panel of Experts has prepared the Master Plans to identify water potential and assess to requirement of water in the State by the year 2050 for Mandovi, Zuari, Talpona and Galgibag river basins covering about 77% of the geographical area of the State.

Besides, under the Bharat Nirman Programme, a programme had been chalked out to bring about 23,521 Ha. of land under assured irrigation during the period from 2005-09 in the State of Goa which included creation of an irrigation potential of 20,921 Ha under major and medium irrigation projects and 2,600 Ha under minor irrigation.

The total outlay proposed during the Annual Plan 2009-10 for all the above schemes is  Rs. 34,079.99 lakh.

 

SCHEMES PROPOSED FOR THE ANNUAL PLAN 2009 -10

 

MAJOR AND MEDIUM IRRIGATION

            It is the endeavor of the Water Resources Department to harness as much water potential as possible through utilization of surface water and ground water of the State. The major achievement in this direction has been made in the major and medium Irrigation Sector to the extent that irrigation potential of 16,637 Ha CCA (25,977 Ha Ultimate) has been created upto the end of the year 2007- 08. Besides, an additional potential of 1,093 Ha (ult.) has been created till October 2008 during the current year 2008-09.

During the year 2007-08, against the outlay of Rs. 12,096.34 lakh, the actual expenditure was Rs. 11,816.55 lakh. Against the outlay of Rs. 11,673.32 lakh during the year 2008-09, an expenditure of Rs. 2,822.42 lakh has been incurred upto October 2008 and the total expenditure anticipated for the year is Rs. 1,60,31.26 lakh. The total outlay proposed under major and medium irrigation projects during the Annual Plan 2009-10 is Rs. 20,236.16 lakh to create an irrigation potential of 3,325 Ha.

 

1. Salaulim Irrigation Project (SIP)

The total irrigation potential of this project is 9,686 Ha. (CCA) i.e. 14,326 Ha (Ultimate) including the command area development works to the full extent. Out of this, potential of 9,537 Ha (CCA) i.e. 14,106 Ha (Ultimate) has been created. Due to curtailment of Branch IV of distributory D3, 220 Ha of ultimate potential is deleted from 14,326 Ha. Although examination of utilization of this potential is being studied, the chances of success appear to be bleak. The project stands almost completed except for matters related to rehabilitation and land acquisition.

 The Project has a water supply component of 160 MLD for domestic and industrial use. In addition, permission has been granted to the PWD for use of 220 MLD of water for expansion of the Salaulim water supply scheme.

During the year 2007-08, against the outlay of Rs. 532.34 lakh, the actual expenditure was Rs. 436.58 lakh. During the year 2008-09 against the outlay of Rs. 484.04 lakh, expenditure incurred upto October 2008 is Rs. 259.94 lakh of which Rs. 15.92 lakh is towards re-habilitation of people from the project area. The total expenditure anticipated for the year is Rs. 520.31 lakh. The proposed outlay for the Annual Plan 2009-10 is Rs. 969.97 lakh towards residual works - final settlement of bills, salaries of the staff, maintenance charges of machinery and equipment, security arrangement of the dam site etc.

 

2. Tillari Irrigation Project (TIP)

This inter-State joint venture of the Governments of Maharashtra and Goa across river Tillari was started in 1986 and approved by the Planning Commission in 1990 for Rs. 217.22 crore based on 1987-88 rates at creating an ultimate irrigation potential of 24,618 Ha (16,978 Ha CCA) for Goa State, besides providing 57.43 MCM for non-irrigation purposes. The actual cost of the Head works is shared between the Government of Goa and the Government of Maharashtra in the ratio of 73.30:26.70 respectively subject to final adjustment as per the project clearance by the Planning Commission.  However, after review of the project by the Government of Goa, the GTIDC has mapped the actual cultural command area which is 14,521 Ha CCA. Due to this, there is a saving to the tune of 57.60 MCM of water which will be utilized for domestic, industrial and other non agricultural requirements of Pernem, Bardez, Bicholim and Tiswadi talukas. Upto October 2008, 5,751 Ha CCA i.e. 8,339 Ha (Ultimate) potential has been created under the project out of which 1,093 Ha has been created during the year 2008-09 till October, 2008. The latest estimated cost of the project based on 2007 rates is 1,390.04 crore and Goa’s share works out to Rs. 965.00 crore. The expenditure incurred by the Government of Goa as on March 2008 was Rs. 608.48 crore which included an amount of Rs. 347.00 crore advanced to the Government of Maharastra towards share capital for common works. The balance canal works of the project are in progress and are planned to be completed by May 2010.

9. Water Resources Development Works/Water Conservation (Inter-linking of Rivers and Post- Monsoon Water Harvesting)

 

This scheme is ideal to overcome the precarious water shortage situations arising due to monsoon failures as well as to augment the future water requirement in the State. Considering the geo-physical structure of the State, and boosted by the resounding success of the inter linking of rivers and post monsoon water harvesting programme, the State has undertaken construction of a series of bandharas for augmentation of water sources to water treatment plants at Opa in Ponda taluka, Assonora in Bardez taluka and Dabos in Sattari taluka to help in ground water re-charge, for diversion of water and to create storage in the riverine system as well as in the river banks by retarding the interflow of ground water into the riverine system. A total number of 170 bandharas have been planned on various rivers/ nallahs out of which 120 bandharas holding a total storage of 40.77 mcm have been completed as on date. At present construction of 7 bandharas holding a total storage of 0.14 mcm is in progress. An additional 43 bandharas holding a total storage 2.34 mcm are planned for implementation during the year 2009-10.

A notable feature of these water resources development projects is that the benefits have come without any environmental destruction /degradation and their design features ensure that rivers do not silt up due to the storages.  Beneficial effects of this scheme have been felt in a tangible and substantial way and agriculture has vastly benefited due to the uninterrupted supply of irrigation water thereby opening up innumerable avenues for growth and prosperity of the farmers. The ground water reserve in the basins has also been built up through recharge providing a tremendous boost to irrigation and drinking water supply in the local remote areas.

The work of inter-linking of Madei river at Ganjem to Khandepar river at Opa is progressing in full swing. The work is almost completed except for construction of gravity pipeline for a length of 3 Kms. which is also in progress. The scheme will be fully operational by February 2009 and will augment 30 MLD of water to Opa Water Works especially during the lean season of the year for supply to Ponda and Tiswadi talukas.

10. Roof-Top Rainwater Harvesting Scheme (New Scheme)

Although Goa State enjoys advantages vis a vis the rest of India in water resources by virtue of its hydro-meteorological endowments, the future scenario of availability of water is a matter of grave concern. Goa’s fast growing economy with tourism as its mainstay and the concomitant floating population and urbanization that it has generated, are fuelling an increasing demand for water. Besides, many areas in the State still face acute water shortage during the lean season even with all the best efforts to provide universal piped water supply. A major part of Goa’s requirements for water is being met from the dry weather base flow of streams and rivers and also from the storages built by the Water Resources Department. However, owing to topographic, geological and other natural constraints and the need for environmental preservation, it may be difficult to bridge the gap between the projected demand and availability of water. Therefore, there is an urgent need to fashion, adopt and popularize an appropriate water management technique which is simple, practical, cost-effective and capable of adoption without complex technical inputs. One such scheme which is best suited and can be profitably adopted to supplement and complement the existing systems of water supply in Goa is Roof-top Rain Water Harvesting. In view of the above, the State has introduced the above mentioned scheme which is proposed to be implemented during the Annual Plan 2009-10.

A provision of Rs.25.00 lakh is proposed for the Annual Plan 2009-10 towards subsidies and other expenditure under the above scheme.

 

III.    COMMAND  AREA  DEVELOPMENT

             

The Command Area Development (CAD) programme was launched in 1974-75 with the objective of improving the utilization of the potential created and optimizing agricultural production and productivity from irrigated lands on a sustainable basis by integrating all the functions related to irrigated land under agriculture through a multi-disciplinary team under Command Area Development Authority. The State has been implementing the CAD programme since 1980 in the command areas of Salaulim Irrigation Project (SIP) and Anjunem Irrigation Project (AIP). The CAD work of Anjunem is completed and Salaulim is almost completed. The CAD works of the Tillari Irrigation Project (TIP) are executed by the Goa Tillari Irrigation Development Corporation (GTIDC) so as to complete the same by 2011-12. The activities of the WUAs will commence only after the irrigation network system is made operational and handed over to the WUAs for operation and maintenance in a phased manner.

The achievements under CAD for the three projects as on March 2008 are as follows:

It is expected to cover another 79 Ha under SIP by the end of the year. The expenditure anticipated for the year is Rs. 211.12 lakh. An amount of Rs. 202.35 lakh is proposed for the Annual Plan 2009-10 to cover an area of 389 Ha in the command of SIP as well as to take up maintenance and repair works of the water courses and field channels.

              

 3.  Land shaping /Leveling and Warabandi

            In order to increase the potential in the Command by using canal water economically and to increase the total agricultural production with the help of active participation of the beneficiaries, Water Users’ Associations (WUAs) in the Command Area of SIP and AIP are formed. In case of AIP almost entire command is utilized. Efforts are being made to form more WUAs in SIP.  Warabandi is based on available irrigated area and is phased accordingly.

The work of land leveling/ land shaping in AIP and SIP has been completed. The achievement in land leveling/ land shaping as on date is 326 Ha in case of SIP and 593 Ha in case of AIP. No provision is made under the scheme during the Annual Plan 2009-10.

        

 4.  Farmers’ Training

             Activities such as krishi melas are organized in villages specially during the rabi cropping season to help farmers to procure all their inputs such as seeds, fertilizers and crop loans in time. Tours and farmers’ training programmes are organized within and outside the State to update their farming knowledge and educate them in the latest techniques of irrigated farming. Field demonstrations of sugarcane, oilseeds and pulses are conducted in farmers’ fields in the command of SIP, AIP & TIP to enable farmers to cultivate suitable crops in irrigated areas. Adoptive and water management trials are taken up in various crops such as sugarcane, paddy etc. to demonstrate to the farmers to obtain maximum yield of irrigated agriculture. During the year 2007-08, against the outlay of Rs. 8.00 lakh, the expenditure was Rs. 9.65 lakh. No provision was made during the year 2008-09. An amount of Rs. 9.00 lakh is proposed for the Annual Plan 2009-10. However, no specific target has been fixed.

        

IV.  FLOOD CONTROL, DRAINAGE AND ANTI-SEA-EROSION

The onslaught of the south-west monsoons in Goa leads to heavy intensity precipitation in conjunction with the high tides creating drainage congestions in low lying areas resulting in flooding. Various works are undertaken to control/prevent floods, improve the drainage conditions of nallahs and rivers and also curtail anti-sea erosion in susceptible areas.

During the year 2007-08, against the outlay of Rs. 1,121.00 lakh, the expenditure was Rs. 1809.80 lakh. During the year 2008-09, against the provision of Rs. 2,277.00 lakh, upto October 2008, the expenditure incurred is Rs. 646.18 lakh. The expenditure anticipated for the year is Rs.4,021.07 lakh. An outlay of Rs. 6,182.00 lakh is proposed for the Annual plan 2009-10. It is proposed to construct protective embankment for a length of 23.000 kms. Out of the total provision, an amount of Rs. 210.00 lakh is earmarked for implementation of the ST sub-plan.

 

1.  Flood Control

Plain land in the State is restricted to a few kilometers from the coastal line and since rivers flowing through the plain lands have very flat slopes at the estuarine reaches, acting as back waters of the sea, the tidal effect is felt right upto the foothills of the Western Ghats.  Though area wise the extent of flooding is small, it covers a substantial portion of the available plain land and the effect of floods becomes all the more apparent when the heavy precipitation coincides with the high tide of the sea.   Mining activity too has aggravated the flood problems on account of indiscriminate felling of forests in the mining areas leading to uncontrolled erosion and excessive silting of the natural watercourses.

The Department has prepared flood mitigation programme in Sanquelim, Bicholim, Ponda and Cuncolim areas and the works are taken up as per the sanction from the Government.  In Sanquelim & Bicholim, works such as removing of bottle necks and fixing of pump have been completed to ease the flow of flood water through the river. Ponda & Cuncolim works are proposed to be taken up by availing assistance from the Ministry of Water Resources.

During the year 2007-08 against the provision of Rs. 640.00 lakh, funds were utilized to the tune of Rs. 913.45 lakh to construct protective embankment of length 6.115 kms. During the year 2008-09 against the provision of Rs. 879.60 lakh, funds to the extent of Rs. 296.38 lakh have been spent upto October 2008 to construct protective embankment of length 3.135 kms. The expenditure anticipated for the year is Rs. 2,137.56 lakh to cover the balance target of 6.865 Kms. will be covered.  An amount of Rs. 3,822.00 lakh is proposed for the Annual Plan 2009-10 to protect a length 12.000 kms  with employment generation of 13.80 lakh mandays

 

2. Anti-Sea Erosion

            Goa has a coastline admeasuring 105 Kms from Terakol in Pernem, North Goa, to Polem in Canacona, South Goa. A major portion of the vast shoreline comprises the beaches, strewn with extensive sand dunes, wild vegetation and village hamlets of the fishing community. Besides, major townships are also located on the riverbanks and seashores. Besides, there are a number of estuaries/rivers joining the Arabian sea, which carry heavy floodwaters during the monsoons causing damage to the riverbanks in the estuarine reaches. Erosion of the beaches has been observed at a number of sites in Pernem, Bardez, Canacona and Salcete talukas. Though temporary measures such as stepped sea walls, earthen embankments, concrete blocks, rubble wall protected by geo-grid net etc have been implemented, many urgent works need to be taken up to tackle erosion problems.

            On the recommendations of the Coastal Planning Development Advisory Committee (CPDAC), anti sea erosion measures have been taken up at Ajoba Temple at Keri for a stretch of 1600m of coastline at Sunset Beach at Betalbatim in Pernem and Salcete Taluka respectively which have been formulated as per the design prepared by Central Water Power and Research Station (CWPRS) Pune, and both works have been tendered and clearance has been obtained from the Goa State Works Board (GSWB). The work orders have been issued and execution of work has been initiated in Keri for a stretch of 1620 mts at a cost of Rs.7.56 crore and at Betalbatim for a length of 880 mts at a cost of Rs. 4.81 crore. Besides this, various other anti sea erosion measures like sea walls, concrete blocks, revetments, dykes etc are taken up to reduce damages along the seashore in Talpona area as well as in Tiswadi, Pernem, Salcette and Bardez Talukas.

         Besides this, the State has participated in Government of India’s project for preparation of Project Technical Assistance (PPTA) on sustainable coastal protection and management programme in Goa, for which Consultants have been appointed by the Asian Development Bank. The Technical Assistance Project will be used for sustainable coastal protection and management in the States of Goa, Karnataka and Maharashtra. Under this project ADB consultants have identified two sub project sites i.e. Coco beach and Colva beach in Goa. In this regard, the ADB consultants have already started work and submitted the interim report which was discussed in the State Level Working Group meeting held on 4/11/2008. The final report is expected by January 2009.

Besides, financial assistance has been availed from NABARD for anti-sea erosion works. NABARD has sanctioned an amount of Rs. 11.75 crore, out of which a sum of Rs. 235.00 lakh has been released to the Department as mobilization/start-up advance, which will be utilized for implementing anti-sea erosion works initiated by the Department in Pernem and Salcete Talukas.

During the year 2007-08, against the outlay of Rs. 230.00 lakh, an expenditure of Rs. 447.16 lakh had been incurred to construct protective measures for a length of 0.893 Kms. An amount of Rs. 863.44 lakh had been approved during the year 2008-09, against which an amount of Rs. 178.15 lakh has been spent upto October 2008 to protect a length of 0.286 Kms.  The expenditure anticipated for the year is Rs. 1,267.37 lakh.  During the Annual Plan 2009-10 an outlay of Rs. 1,646.00 lakh has been proposed to protect a length 2.500 kms with employment generation of 5.94 lakh mandays.

 

3.  Drainage

Various measures are adopted to improve the drainage systems by removing congestion through desilting, river training, etc. not only in the coastal belts but also in urban areas to protect the same from getting flooded due to congestion of drains passing through these areas. 

During the year 2007-08, against the outlay of Rs. 251.00 lakh, an expenditure of Rs. 449.19 lakh had been incurred to construct protective measures for a length of 5.767 Kms. An amount of Rs. 533.96 lakh had been approved during the year 2008-09, against which an amount of Rs. 171.65 lakh has been spent upto October 2008 to protect a length of 3.050 Kms.  The expenditure anticipated for the year is Rs. 616.14 lakh to achieve the balance target of 4.450 Kms.  During the Annual Plan 2009-10 an outlay of Rs. 714.00 lakh has been proposed to protect a length 8.500 kms with employment generation of 2.58 lakh mandays.

 

 V.  WESTERN GHATS DEVELOPMENT PROGRAMME (WGDP)

            In Goa, 3 talukas viz Sattari, Sanguem and Canacona lie in the Western Ghats region. Out of the total geographical area of 1,678.32 sq kms of these 3 talukas, the cultivable area is 398.11 sq. Kms. i.e. 39811 Ha which is 10.75 % of the total geographical area. This region being hilly, deserves greater attention in respect of irrigation for intensive cultivation and to improve the economic status of these backward areas.

            The Water Resources Department aims to ensure regular irrigation facilities in the Western Ghats region so as to raise the standard of living and improve the socio-economic conditions of the farming population by helping them to increase their agricultural produce. Due to hilly and undulating topography of the Western Ghats, sizeable area is not available for cultivation and hence minor irrigation schemes having a smaller gestation period such as open wells, tube wells, bore wells, lift irrigation schemes, tanks and bandharas are adopted to serve these hilly areas.

During the year 2007-08, against the outlay of Rs. 222.50 lakh, an amount of Rs. 206.92 lakh was spent to create a potential of 112 Ha. During the year 2008-09, against the provision of Rs. 275.50 lakh to create an irrigation potential of 140 Ha, the expenditure incurred upto October 2008 is Rs. 43.04 lakh to create a potential of 26.87 Ha. The expenditure anticipated for the year is Rs. 191.66 lakh to achieve the balance target of 113 Ha. will be achieved.  An amount of Rs. 492.00 lakh is proposed for the Annual Plan 2009-10 to create irrigation potential of 185 Ha. by completing all on-going schemes and taking up new ones.

 

VI.  BHARAT NIRMAN PROGRAMME (IRRIGATION SECTOR)

            The policy issues related to objectives of Bharat Nirman (Irrigation Sector) are set out in the National Common Minimum Programme (NCMP) document. The Bharat Nirman Programme envisaged creation of 10 million Ha. i.e. one crore Ha, additional assured irrigation during the 4 years period, i.e. from 2005-09 all over the country.

            In view of the above, a programme had been prepared to bring about 23,521 Ha. of land under assured irrigation plan during the period from 2005-09 in the State of Goa which included completion of all on-going projects viz. Salaulim and Tillari as detailed below:

As per the Bharat Nirman Programme in Goa, during the 3 years’ period from 2005-08, irrigation potential of 8,713 Ha. has been created. The total potential created during 2008-09 upto September, 2008 is 1,140 Ha. An additional Irrigation potential of about 5,045 Ha is expected till the end of the year 2008-09.

           There was no separate budget provision for this programme. However, provision for expenditure was made from the budget provision under major and medium irrigation (excluding water development), minor irrigation (excluding water resource development programme) and hill area development programme (Western Ghats).

            The achievement is less as compared to the target set is mainly due to Tillari Irrigation Project which is in the advanced stage of completion. The implementation of the project is delayed due to land acquisition process which could not be completed in time. This has delayed the further progress of canals in Goa. However, efforts are being made to complete the process at the earliest and complete the canal net works. Also CAD scheme proposal has been submitted to the Government of India to avail assistance. The sanction of the proposal will boost to expedite the progress in CADWM.
