Objective of a Typical WWS System
To enhance the health and quality of life for
citizens by providing them adequate supply of
clean and good quality of water and safe disposal
of sewage / waste water at reasonable price.
In short, the pursuit of the above objective
would make the appropriate contribution toward
sustainable development.

Typical WSS Issues.
Raw Water Treatment Storage

• Level of treatment
• Mode- insitu / centralized
• Storage Planning

Distribution
Source of Water

• Adequacy of Quantity population, usage pattern
  etc.
• Recharging pattern rate
• Quality

• Distance of the source to usage point
• Mode Pipe / truck / others
• Cost Benefit Analysis

Usage

• Domestic Consumption
• Industrial
• Agricultural

Stakeholders

• Socio-Economic pattern of the end-users
• Industries
• Private Service Providers
• Government bodies
• Regulatory Authorities

Treatment Disposal
Collection

• Quantity
• Mode- Centralized / at source
• Cost
• Disposal Method

• Quantity of municipal wastewater / effluent
• Source Segregation strategy
• Method of collection
• Collection efficiency

WATER SUPPLY
Chennai Status quo practices in Peri-Urban
interface

• Piped network provided by panchayats
• (Household connections in some areas and public
  standpipes)
• Wells Borewells
• Provision by tankers

• Buying from licensed tankers
• Buying packaged water (cans, bottles, satchets)
• Private builders/suppliers own water supply
  systems (RO Plants recent trend)

• Own individual wells borewells
• Rainwater harvesting
• Unauthorized connections / procurement

SANITATION
Chennai Status quo practices in Peri-Urban
interface

• Drainage connections to select areas leading to
  centralized
• treatment (small proportion)
• Community Latrines
• Providing garbage collection in select areas

• Household Septic tanks / soak pits
• Dumping of garbage in roads

• Community lavatories by NGOs
• Community MSW collection by NGOs in select
  areas.
• Community Septic tanks
• Open defecation and pollution of surface water
  streams

Way Forward- Some Action Points for consideration
(Contd.

• Incommensurate expansion of peri-urban areas
  WSS System to be accounted for at the planning
  permit stage itself.
  Example especially south of Chennai (IT
  Corridor and the East Coast Rd)
• Open up for Private Sector Participation (PSP)
  Government to open up the management of the Water
  Sewerage service provision to the participation
  of the private sector
• Inadequate state water supply (Water Security)
  is grossly inadequate and unreliable for users
  needs identification of fresher sources and
  means need to be explored (Establish perennial
  water sources)
• Networked water sewerage system (safe disposal
  of wastewater) need to cover the entire
  peri-urban area (currently covering only 6) and
  the networked sewerage system is to cover most of
  peri-urban areas (which is currently non
  existent)
• Awareness building among the peri-urban residents
  about the health externalities associated with
  inappropriate water sanitation system
• Desilting clearance of all the surface water
  bodies in and around the metro and peri-urban
  areas
• Prevention of untreated / unauthorized discharge
  by strict monitoring of effluent / sewage
  discharge to the water bodies (lot of gap left to
  be covered)

10
Way Forward- Some Action Points for consideration
Specific Case

• Environmental Management Plan (EMP) (Select
  Sector IT Corridor) This is to cover the
  following
• Mapping of the entire Peri-urban area covered
  (under different Administrative control)
• Accounting complete entities population
  covered- industries/companies, commercial
  establishments, Apartment complexes, colleges,
  hospitals, individual households
• Estimation of current projected population
  including permanent floating
• Preparation of complete Water Mass Balance
  covering Total water requirement categorizing
  the break-up quantity quality of water required
  depending on the intended usage (for Class 1 2)
  .
• Mapping of the available water resource to meet
  the supply-demand of the sector and net water
  requirement after closing of the loop
• This is to include the potential class 2 water
  available through wastewater recycle (at source
  wherever possible decentralized)
• Potential tapping harvesting of the storm water
  within the system
• The appropriate treatment for wastewater recycle
  and distribution
• Identification of all the stakeholders-
  Government body, private sector, community,
  industry, NGO,
• Strategizing the roles of all the stakeholders
• Adopting of rural / semi urban communities within
  the sector by each industry to meet the
  infrastructure need.

11
Way Forward- Some Action Points for consideration
Specific Case

• Potential areas of private sector participation
  based on EMP (Select Sector IT Corridor)
• Water resource identification exploration of
  the NET WATER REQUIRED FOR THE SECTOR as per
  EMP
• Design of a complete Integrated Water Management
  System (IWMS) covering collection, conveyance,
  treatment, delivery of the
• Raw Water (Class 1 2)
• Wastewater collection
• Wastewater treatment (decentralized wherever
  possible)
• Storm water collection system
• Role definition of the identified stake holders
• Installation and maintenance of the IWMS on a BOO
  basis as is done for the highways and other
  infrastructure projects
• Awareness building with the communities,
  residents, commercial industries within the
  sector
• Resource mobilization and planning
