Towards Cleaner India
Parameter India United Nations’ Guidelines

Average no. of toilets per school 2.1
Water supply in urban areas (hours/day) 3.3 hours
Situational analysis: Challenges and Opportunities (1/2)

Situational analysis: Challenges and Opportunities (2/2)
Sanitation 1. Non-segregation of waste water from utilities and toilets, results in mixing of water and inability to treat entire water for re-use
2. Disposal of sewage directly into the rivers
3. Improper garbage disposal
1. Look at waste water from toilets and utilities as opportunity than a burden
2.Requirements for irrigation and flushing purposes can be fulfilled by treating waste water from toilets and reusing
3. Separate waste water at house/school/any premises level: Utilities vs. toilets
4. Segregation of human, animal excreta from water at community drain level – excreta to be used as manure after decomposition
Drinking water
1. Wastage of drinking water during transportation
2. Unavailability of sufficient water, which can be treated and used for drinking
3. Water leakage during storage
Drinking water 1. Treated waste water from utilities is usable for drinking
2. Rain water harvesting to increase ground water level
3. Utilizing rain water falling in land
Challenges Opportunities
Sanitation
India at global level: Access to sanitation
Source: References [f]
India at global level: Scarcity of water
Source: References [g]
Solution: An overview
Sewage treatment plant
1. Decentralize: Area level (one per 50 sq. kms)
Centralize: Zone/city level
2. Public Pvt. Partnership
BOLT – Build, Operate, Lease, Transfer
Allow local private players to build sewage treatment plants, run it as a business, transfer to government
3. Offer them benefits like lesser interest rates on loans, business opportunities
Rain water harvesting
1. Incentivize rain water harvesting scheme for residential area
2. AADHAR card linked monthly monetary payment to the household
3. Increase in ground water level
4. Stored water to be used for utilities
5. Financial inclusion
Public toilet hubs and portable toilet units
1. BOT - Build, Operate, Transfer
Allow private companies / individuals to invest and operate
2. Usability: Rural and congested urban areas
Potable drinking water
1. Water purification plants
Community level: Small distillation units
City / village level: Pipelines to individual households
2. Subsidized solar water disinfectors

Sewage treatment plants: A new dimension
•Decentralize sewage treatment plant using PPP model
•Adopt of suitable state-of-the-art technology to convert the wastewater into potable drinking water
•As a result, reducing the negative impact of releasing untreated sewage into the environment (river)
• Setup of at least one plant covering approximately 60 sq.km of area with coverage of a population of minimum 2 lakhs
•Approx. capacity of the sewage treatment plant is 44.5 MLD
Identification
•PPP Mechanism bounded by contract by Government and concessionaire
• Land should be provided by the Government on lease and cost of power is borne by concessionaire
•Use biogas generated during treatment of sewage to meet part of its power requirements
•No role of government on consumption and reuse of potable quality recovered water
•Responsibility of quality and standards of services with subsequent independent checks will lie with the concessionaire
Implementation
•Debt equity ratio of 70:30, which is commonly used for infrastructure projects in India
•Operation and maintenance for 30 years in PPP mode with a debt equity ratio of 70:30 is both financially and economically viable
•All operating and maintenance costs are to be increased annually by 3%
•Price escalation of recycled water at the rate of 3% per annum may be assumed by the concessionaire
•High returns from the project can be gathered after the end of 30 years where IRR is minimum 15% and NPV is positive
Continuation
Rain water harvesting: Incentivize
Identification
Area: Rural and urban
Type: Residential, individual households
Aim: Incentivize households to install rain water harvesting system
Implementation
The scheme plans to incentivize every household with a monthly incentive.
Cost of installing rainwater harvesting system for 200 residents = Rs. 25, 000
Implied cost for a family of 4 = 25,000/200 = 125Rs.
Average cost for a unit for single house = Rs. 3000 to Rs. 5000
Suggested incentive = 100 Rs. per month
Payback period = 3 to 5 years
Use bank account linked to AADHAR card for transactions
Continuation
Future scope:
The model can, then, be extended to:
1. Commercial and institutional entities
2. Society / community level project undertaking of installing rain water harvesting system
3. Incentivizing for saving the water

Appendix
1. Toilets
Total schools in India (27 states) = 6,12,131 + 98,054 = 7,10,185
Total schools without toilet = 35773 + 10,581 = 46,354
% of total schools without toilets = 6.53%
2. Water facility in school toilets
Total toilets in schools = 1252844 + 245892 = 1498736
No. of school toilets without water facilities = 64255 + 8911 = 73166
% of school toilets without water facilities = 4.9%
3. Toilets per school
Total schools in India (27 states) = 6,12,131 + 98,054 = 7,10,185
Total toilets in schools = 1252844 + 245892 = 1498736
Average no. of toilets per school = 2.1
4. Student-to-toilet compartment ratio
Total enrolment in schools (excluding enrolments in class XI, XII attached to degree colleges) = 140404561 + 61052501 = 201457062
Total toilets in schools = 1252844 + 245892 = 1498736
Student-to-toilet compartment ratio = 201457062 / 1498736 = 134.4
