II. Necessity Of The Scheme:

The existing open drain system is not functioning satisfactorily. The water is stagnating in many places and due to that mosquitoes and flies are developed, which cause health hazards. In order to improve the hygienic conditions, underground sewerage system is a must for Rameswaram Municipality.

III. Population Projection:

In designing sewerage system for any town the important factor is the present population and its expected rate of growth. The concept of the base year 2019 is considered for projecting the intermediate population for 2034 (15 years from base year) and the ultimate population for 2049 (30 years from base year).

IV. Detailed Description Of The Proposal:

The proposed UGSS Scheme is designed for the ultimate stage i.e. year 2049.

The Sewerage work is divided into the following five categories and described subsequently.

• House connections and local sewerage.
• Main and trunk sewers.
• Pumping stations.
• Pumping main.
• Sewage Treatment plant.

House Connection And Local Sewerage Including Branch Sewers:

The total number of house service connections calculated as 9206 Nos. The Rameswaram Municipality is divided into two parts in North- South directions for UGSS purpose, the Northern side is termed as Zone I and the Southern side is termed as Zone II.

Main And Trunk Sewers :

The total main and trunk sewer covers a total stretch of 13760 m and total manholes of 484 Nos.

Pumping Station:

The sewage generated from the Zone I is collected and is proposed to be conveyed to MPS near Hotel Tamilnadu. The sewage generated from the Zone II is collected at Sub Pumping Station near Thidal Mariamman koil and is proposed to be pumped to MH.No.14 of Zone-I. The capacity of collection well has been determined in such a way that for any combination of inflow and pumping, the cycle of operation for each pump will not be less than 5 minutes and maximum detention time will not exceed 30 minutes. Pumping quantity is 4.08 mld for intermediate and 5.34 mld for ultimate.

Pumping Main And Pumping Station:

Pumping Stations and Pumping Mains:

i. Main pumping Station (MPS)

ii. Sub pumping Station (SPS)

Sewage Treatment Plant:
