Environmental Impact Assessment - Municipal

EA for the Proposed STP Project Description
1. INTRODUCTION
1.1 PREAMBLE
Dharmapuri Municipality has proposed to establish a 4.86MLD capacity Sewage Treatment
Plant (STP) at Dharmapuri Municipality of Dharmapuri District in TamilNadu. The Sewage Treatment
Plant is designed based on Activated sludge process followed by disinfection system.
Dharmapuri District, which came into existence from 02.10.1965 is situated in the North
western Corner of TamilNadu and is bounded by Tiruvannamalai and Villupuram Districts on the east,
Salem District on the South, Krishnagiri District on the north and Kaveri River on the west. It is located
between latitudes N 11 47’ and 12 33’ and longitudes E 77 02’ and 78 40’. The total geographical area
of Dharmapuri District is 4497.77 Sq Kms, i.e. 3.46% of TamilNadu.
The district has hot and dry summer during the months of March to May and very cold and
misty winter from November to February. The temperature varies from 17 0 C to 37 o C. The Average
annual rainfall is 850 mm. There is a vide variation among the blocks in terms of temperature and
rainfall. The climatic conditions varies because of the vide variation in the topography. While the
northern & western taluks lie around 1000 metre above mean sea level, the southern and eastern parts
consisting of Dharmapuri, Pennagaram, Palacode, Harur and Uthangarai taluks lie at 450 metre above
mean sea level. Of the three divisions, the Dharmapuri division consists of dry areas of Pennagaram
and Harur. Even the Hogennakkal waterfall, which is situated in this part of the district, does not aid
agriculture. The Krishnagiri division comprises fertile areas like Uthangarai, Kaveripattinam and Bargur
blocks as it has a reservoir built across the Pennaiyar River.
