CHAPTER 2Project Description of System HLOCATION AND ORGANIZATIONS Y H IS located ~ in the Dry Zone in the North-Cenaal Province of Sri Lanka. The area lies within the Kala Oya Basinabout 16kilometers (km) south-west of the historic town ofAnuradhapura, thecapital of the North Ceneal Province. Theproject area covers a contiguous area of 106,000 acres (42,898 ha) of irrigable land, out of which 35,000 acres (14,165ha) are old iirigated areas and 71,000 acres (28,734 ha) are newly developed lands.A map of System H is given in Figure 4. System His made up of twelve subsystems, of which H1. H2, H4. H5. H7.and H9 are new settlement areas, and the others are old colonization schemes. During the period when the settlementactivities were under the MDB, the entire system was managed by the Resident Project Manager, Kalawewa. Later,because of the rapid influx of settlers, the system was divided into three. project areas, each under an Resident ProjectManager. The three project areas are Kalawewa (Hl, H2, H6, H7, H8. and H9); Tambuttegama (H3 and H4); andNochchiyagama (H5), as shown in Figure 4.PLANNINGANDFUNDWGBeSides a UNDP-FA0 Mahaweli Master Plan which gave an overview of the development of System H, a full feasibilitystudy was conducted by the Soci&e' Grenobloise &Eludes el &Applications Hydrauliques (SOGREAH) of Grenoble,France, consultant to the MDB in collaboration with local experts. This study was funher reviewed, and the revisedproject was cofinanced by a consortium of donors - the World Bank, the International Development Agency (IDA), theUK, Canada the Netherlands, USAID, and the EEC.H5 AREA OF SYSTEM HSource of Water and Main Features of Delivery SystemThe H5 area is commanded by the Kalawewa Reservoir Right Bank main canal, which is about 45 kilometers (km) long(F'igure 5). The Kalawewa Reservoir is fed by its own catchment and by the waters from the Mahaweli River divertedat Polgolla. The Kalawewa Right Bank main canal supplies water to two subsystems (H4 and H5), of which the lhreetail-endblocksareintheH5area. TheRightBankmaincanalhasacapacityof 1,150cusecs(32.57cubicmeters/second,cumecs). The main canal is muted through a number of existing tanks or reservoirs. They function as regulating tank,and this makes the main canal more responsive to changes in the discharge. The control shuctures at the head of eachreach of the main canal can be activated to replenish the regulating tanks.7
