1. GENERAL INFORMATION ABOUT THE PROJECT AREA

Kollamula village encloses areas of Vechoochira, Perunad and Naranamoozhy Panchayaths. The boundaries of this village are Perunad Village on South, Chethakkal and Athikkayam villages on West, Erumely Villages of Kottayam district and Kumily Village of Idukki District on North and east. River Pampa bifurcates this village into two parts; a portion of Vechoochira Panchayath on right side of River and that of Naranamoozhy and Perunad Panchayath comes on left side of river.

The people depend mainly on shallow wells and small streams for their drinking water needs. Due to the impermeable rocks, presence of water in shallow depth is rare. During summer season, potable drinking water becomes an expensive item. Kollamula Village is identified as a quantity affected village and main quality problem is the presence of high iron content. The existing water supply schemes – RWSS to Vechoochira, RWSS to Arayanjilymon, RWSS to Kurumbanmoozhy are found inadequate to meet the present and future demand of the whole area due to the deficiencies and handicaps in the schemes. This project intended to distribute 2.36 MLD water taken from the 10MLD capacity Treatment Plant of RWSS to Erumely near MES College of Engineering Erumely which was commissioned last year. The completed Components of the present scheme are 1) Clear Water Gravity Main From WTP to Venkurinji Sump ( 250 mm DI K9 - 2300 mtr) 2) 3 LL Capacity Sump and Pumphouse The work of Clear Water Pumping Main From Venkurinji Sump to proposed OlikkalSump and Pumphouse (250 mm DI K9 -1300 mtr) already arranged and will start soon.

2. SCOPE OF WORK AND GENERAL REQUIREMENT

Following are the general scope of the work a) Construction of 6.00 LL GLSR and pump house at Olikkal b) Construction of 3.20 LL GLSR at Thalamuttiyani c) Supply and laying 150 mm DI k9 clear water pumping main from Olikkal pump

house to Thalamuttiyani GLSR d) Supply, erection and commissioning of clear water pumpset at Venkurinji sump for Olickal Sump cum pumphouse.(100 HP C/F pumps with total head 119m) d) Supply, erection and commissioning of clear water pumpset at Venkurinji sump for Pampirikkumpara GLSR (30 HP C/F pumpset with total head of 170m) e) Supply, erection and commissioning of clear water pumpset at Olikkal sump for Thalamuttiyani ( 20HP C/F pumpsets with total head of 68m)
