Before 3/2003:

O & M of bulk WSS : KUWS & D Board

O & M of Distribution System : HDMC

Targets

• To improve the Service level thro’ control of UFW, illegal connections, etc.

• To reduce huge gap between Income and Expenditure

Main Contents of G.O. No.UDD25.2002 B’lore Dtd:24-03-03

Status

• Poor Water Service levels due to improper maintenance

• Huge gap between Income & Expenditure.

After 3/2003:

As per G.O. No.UDD25.2002 B’lore Dtd:24-03-03

O & M of both bulk & Distribution – KUWS & DB.

Page 39: karnataka Urban Water Supply & Drainage Board Bangalore · WATER SUPPLY MANAGEMENT - A CASE STUDY OF HUBLI-DHARWAD By K.P. Jayaramu, Executive Engineer, Karnataka Water Board, Jn

PRORATA CHARGESMethod of Calculation : For Bulk Consumers

1. Capital Cost

Est cost of EIWSS (Revised) Scheme = Rs. 49.17 Crores

Est Cost of Augmentation of Water Transmission System in Hubli

Dharwad Twin Cities

= Rs. 42.42 Crores

Total = Rs. 91.59 Crores

Est Capital Cost = Rs. 92.00 Crores

2. Unit Prorata Cost

Quantity of Water produced = 73.80 MLD

Prorata Cost = 92.00 x 100

73.80

= 124.66 lakhs/MLD

Say 125.00 lakhs/ MLD

3. Calculation of Prorata Cost for Railways, Hubli

Ultimate Requirment of Water 5.45 MLD

Prorata Cost = 125.00 X 5.45 = Rs.681.25 Lakhs

Approximate Cost of Dedicated Water Supply Scheme to Railways, Hubli Rs 2400.00 Lakhs

Hence, it is economical to get water from Hubli-Dharwad water supply scheme by paying prorata

cost.

Page 40: karnataka Urban Water Supply & Drainage Board Bangalore · WATER SUPPLY MANAGEMENT - A CASE STUDY OF HUBLI-DHARWAD By K.P. Jayaramu, Executive Engineer, Karnataka Water Board, Jn

Method of Calculation : For Retail Consumers

1) Prorata Cost towards Bulk W/S Scheme

1.1) Capital Cost

Est. Cost of EIWSS (Revised) Scheme to Hubli Dharwad . . . . . Rs. 63.84 Crores

Est. Cost of Transmission Main from Amminbhavi to Hubli . . . . Rs. 36.00 Crores

TOTAL . . . . . . Rs. 99.84 Crores

Est. Capital Cost Say, . . . . . Rs. 100.00 Crores

Deduct Govt. Grant of 23 1/3% (-) Rs. 23.33 Crores

BALANCE Rs. 76.67 Crores

1.2) Unit Prorata Cost

Quantity of Water produced = 73.80 + 40.0 MLD =113.80 MLD

Unit Prorata Cost / KLD = 76.67 x 10000000

113.80 x 1000 = Rs. 6737.00

1.3) Calculation of Prorata Cost towards Bulk, W S S

Assuming rate of supply as 135 LPCD & 5 persons per house

Water Quantity per site= 135 x 5 = 675.00 Liters/day= 0.675 KLD

Prorata Cost per house = 0.675 x 6737.00 = Rs. 4547.48

Say Rs. 4548.00

For each house taking Floor Area =150.00 Sqm

Therefore, Prorata cost per Sqm of Floor area = 4845 / 150 = Rs. 30

Say Rs. 30.00 per Sqm of floor area.

2. Prorata towards Feeder Network and Reserviors.

Cost of Feeder Network and Reservoirs . . . . . Rs. 100.00 Crores

Deduct Govt, Grant 23 ½ % . . . (-) Rs. 23.33 Crores

Balance Cost . . . . . Rs. 76.67 Crores

Present population (Projected for 2003) = 8.50 Lakhs

Assuming 5 persons per House

Cost per House = 76,67,00,000 x 5

-------------------- = Rs. 4510

850.00

Taking Floor up area as 150 Sqm

Prorata cost per Sqm of floor area = 4510.00

---------- = Rs. 30.06

150.00

Say Rs. 30.00 per Sqm of floor area.
