Comprehensive Planning of Water Supply Service improvements In the following ULBs (1) Ananthapur Municipal Corporation,(2) Chittoor Municipality and (3) Badvel MunicipalityBadvel Municipality – Detailed Project Report (Final) - Environment3.1.4 MeteorologyBased on the Agro-climatic conditions the District falls under Southern and scarce rainfall zone. In southernzone rainfall ranges from 700 to 800 mm while it is 500 to 700 mm rainfall in scarce rainfall zone. Kadapa(YSR) is one of the districts in Rayalaseema area, with an un-even, isolated rainfall in different parts of thedistrict and with large dry tracts. The rainfall of Kadapa district is mainly influenced by South-West monsoonand part of the district viz., Rajampet, Kodur, Rayachoty and L. R. Palli Mandals receiving the rainfall fromNorth-East Monsoon also. The normal rainfall of the district is 700 mm as against the state average of 940mm.The weather of the town is generally hot and partially humid which is common in any tropical area. Thesummer usually extends from February to June, the rainy season is from July to October and winter seasonis from November to January. The temperature of the town varies from 20 0 to 45 0 C. The average annualrainfall in Badvel town area is about 700 mm. For the last two years draught condition is prevailing causingfall in the static water table in the bore wells with consequent drop in yield from them. As a result there is anacute problem of water supply during the summer season. During winter the temperature generally rangesfrom 20 0 to 27 0 C.3.1.5 Surface water Status and QualityThe rivers in the Kadapa district are non-perennial in nature and mostly remain dry throughout the year. Theimportant rivers in the district are Ponnai, which is a tributary of river Palar, and Swarnamukhi. They rise inthe Eastern Ghats and finally enter Nellore district. Some of the other important rivers of the district are theKushasthali, Bheema, Bahuda, Pincha, Kalyani, Araniyar and the Pedderu. In addition, there are a numberof small streams flowing by the hills in the district.The river Sagileru and the river Penna are the main rivers passing near Badvel, these are not perennial. Insummer there is no sub-surface flow in these rivers. As such it is not possible to collect any water from thebed of these rivers.Surface WaterOther surface water sources near Badvel are:• Surface water of Lakshmi Palle Tank.• Surface water of Badvel Tank.• Surface water of the SPVBR reservoir.Of the above three sources, the Lakshme Palle Tank and Badvel Tank are traditionally used for supplyingirrigation water for cultivation purposes. It is practically impossible to convert these into drinking watersources. The tanks receive only rainwater and hence not reliable from the point of sustainability. It has beenobserved that the tanks become dry in summer period. Hence, these sources cannot be considered as asustainable source of water for Badvel town.Surface Water of SPVBR ReservoirThe water from SPVBR reservoir, which is a part of Telugu Ganga Project, has sufficient capacity to meetthe requirements of Badvel town for the design horizon of 2040. This reservoir is popularly known asBhrahmasagar Reservoir. The reservoir is located at a distance of about 30 km from Badvel town. Thesalient features of the SPVBR are given below:• Reservoir bed level : 198.00 m• Maximum water level (MWL) : 217.50 m• Reservoir bund level : 220.50 m• Lowest bed level : 170.00 m• Full reservoir level : 215.00 m• Total capacity of reservoir : 17.735 TMC13
