1. Introduction
Urban Andhra Pradesh was declared Open Defecation Free by the Honourable Chief Minister,
Shri Chandrababu Naidu, on October 2, 2016. Achieving this has been a major success in terms of
infrastructure building, human development, sanitation, and public health. It was the crucial first
step in creating an Andhra Pradesh whose citizens can enjoy clean and sanitary cities; however, it is
not the only requirement. Over ninety percent of urban households in Andhra Pradesh use on-site
sanitation systems, such as septic tanks, pit latrines, and soak pits.
As these containment facilities are not connected to any larger system, they need to be emptied
periodically. When emptied, the refuse from these tanks, called “faecal sludge” and “septage,” is
usually thrown directly into the environment without any processing or treatment – this sludge
goes directly from septic tanks into rivers or onto fields, often within municipal boundaries. “Faecal
Sludge” includes the liquids, solids, as well as the fats, oils and grease (scum) that accumulate in
containment units over time, while “Septage” usually refers to the refuse of septic tanks in
particular. As a variety of containment typologies exist in Andhra Pradesh, these regulations will
primarily refer to faecal sludge and septage, though the two terms are used here interchangeably.
This refuse, called either faecal sludge or septage, is harmful and contains many pathogens
hazardous to human health. Accordingly, the unregulated dumping of faecal sludge into the
environment is an ongoing public health and environmental crisis both in Andhra Pradesh and
across the country.
The central government has taken notice. Accordingly, when the Ministry of Urban
Development (MoUD), Government of India formulated the National Urban Sanitation Policy
(NUSP) in 2008 in order to provide urban Indians with clean, healthy, liveable, and sanitary
community-driven cities and towns, a set of recommendations regarding septage (also known as
faecal sludge) was included. The NUSP recommends that septage be collected, transported, and
disposed of properly at well-maintained purpose-built treatment facilities.
There are two major sources of standards and guidelines for septage management in India: The
National Building Code, last revised in 2005 by the Bureau of Indian Standards (BIS); and The
Manual on Sewerage and Sewage Treatment, prepared by the Central Public Health and
Environmental Engineering Organization (CPHEEO) in 2012.
While the CPHEEO Manual assigned responsibility for checking sludge accumulation on a
daily basis and determining emptying times to households, the CPHEEO Manual also
recommended that state and municipal governments draw up action plans and implementation
budgets for extracting, treating, and disposing of the sludge generated in on-site facilities in
accordance with the “Septage Management Guidelines” (MOUD, 2013). Further, the Ministry of
Urban Development in 2016 published set of guidelines on Faecal Sludge and Septage Management
(FSSM) which can provide further support to ULBs.
Faecal sludge and septage management (FSSM) includes the entire process of design,
collection, safe treatment& disposal of faecal sludge /septage based on generation of waste. A
comprehensive program that regulates periodic cleaning of on-site containment, , as well as
septage transport, treatment, re-use, and disposal is important in the context of our rapidly
urbanizing state.
1.1 Current Scenario in Andhra Pradesh
Andhra Pradesh is a rapidly urbanizing state; 146 lakh people, or 29.6% (Census 2011) of the
state’s population live in urban areas, and urban populations are growing at an accelerating pace.
In accordance with the Honourable Chief Minister’s push to create an Andhra Pradesh blessed by
total sanitation, Faecal Sludge and Septage Management, is being accorded highest priority by the
Government of Andhra Pradesh.
There are 14 Municipal Corporations and 96 smaller Municipalities in the state. Of these
combined 110 Urban Local Bodies only five local bodies possess partial sewage treatment plants
(STPs), DPRs are currently being developed to construct underground sewerage systems (UGSSs)
and STPs in some AMRUT towns. None of Andhra Pradesh’s ULBs will enjoy even 50% sewerage
coverage upon the completion of this infrastructure in the short to medium term.
ULB-wise capacities of existing STPs is therefore given following table on the next page.

1.2 The Need for Faecal Sludge and Septage Management system in
Andhra Pradesh
Although Andhra Pradesh is currently in the process of developing and extending
underground sewerage systems, they currently serve less than ten percent of urban households.
While this number mayrise in the coming years, it is not projected to reach fifty percent even in
major towns and cities over the next decade. Furthermore, the majority of municipalities, those not
designated as AMRUT towns, will continue using on- site sanitation (OSS) for the foreseeable
future. Across the world, governments are realizing that conventional sewerage systems, while
advantageous in certain situations, are not a sanitation panacea as they require huge capital
expenditures, consume significant amounts of water, need extensive operations and maintenance
throughout their existence and high skill set at municipal level to maintain.
As a result of these factors, Faecal Sludge and Septage Management is a necessary component
of the efforts to ensure Andhra Pradesh’s towns and cities are clean and sanitary. These efforts will
require developing detailed rules and regulations, refurbishing existing septic tanks and latrines
and developing desludging, transportation and treatment infrastructure.
While municipalities plan for faecal sludge treatment infrastructure, , they should pursue
short-term incremental improvements simultaneously through operationalizing steps outlined in
this document. . These incremental improvements may be prioritized for the first year after these
guidelines become operative, after which point focusing on longer-term solutions will take
These guidelines will regulate collection, treatment, and disposal of faecal sludge and septage
in urban areas in Andhra Pradesh. This following sections details out these guidelines.
2. Operative Guidelines for Urban Local Bodies
Faecal Sludge and Septage Management (FSSM) for the local bodies includes both residential
and non- residential/commercial waste (though not industrial waste). These Operative Guidelines
for FSSM seek to empower municipalities with knowledge, procedures and facilities for planning
and implementing FSSM . In particular, City Sanitation Task Forces (CSTFs) should take up an
active planning and advisory role in cooperation with municipal councils in order to dedicate
appropriate resources and attention to the challenges of faecal sludge management.

d) Municipalities shall evaluate existing containment units and other storage/treatment
systems and modify (in case of variation) based on design mentioned in Annexure 1.
e) Notices should be issued to all property owners whose containment facilities do not meet the
standard septic tank design. National/state aid may be sought in order to financially
support the conversation of improper containment units into sanitary toilets. .
f) Identify insanitary toilets and convert them to sanitary latrines for safe collection and
disposal of waste as per norms set out in Annexure 2.
g) All existing containment facilities should have access covers for each chamber, so that they
can be easily opened during emptying process. Where such covers are not available, it
should be made compulsory for all property owners to provide proper covers.
h) Pursuant to the previous four steps, municipalities must take efforts to build the capacity of
masons and builders to teach them how to construct proper toilets and refurbish improper
already-built containment units. Details regarding the codes that must be followed are
included in the next item.
i) When new containment facilities need to be built, they should be built as septic tanks
designed and constructed as per instructed in the National Building Code, 2005 and
CPHEEO Manual, 2013 which takes reference of design norms from IS: 2470 on Code of
practice for installation of septic tanks - Part 1: Design and Construction and Part 2:
Secondary treatment and disposal of septic tank effluent 1985 (Reaffirmed 1996). The design
norms CPHEEO Manual, 2013 is compiled in Annexure 1.
2.2 Transport
Transport describes the movement of sludge across the service chain from individual septic
tanks and latrines to municipal or regional treatment facilities. Currently, these services are largely
unregulated across Andhra Pradesh, particularly in smaller cities and towns. Municipalities must
take on two tasks: first, they must regulate operators by establishing a system of licensing, which
will facilitate the enforcement of health and safety standards and the prevention of open dumping;
second, they must design a plan to conduct a system of scheduled emptying in which every
containment facility is emptied at least every three years (with more frequent emptying for public
accommodations, community/public toilets, and the like). This scheduled emptying will be
contingent on having completed a detailed survey of individual containment facilities (as referred to
in Section 2.1), and so may not be operationalized immediately; nevertheless, ULBs shall develop
plans to do so.
ULBs must take the following steps (some are also required in section 2.1, but at listed here for
a) Determine how many households use on-site containment systems and ascertain how much
sludge they can contain in order to determine the amount of sludge that will be emptied
every year (presuming a three-year emptying cycle for individual households and more
accelerated cycles on an as-assessed basis for public and commercial facilities).
b) Determine how many septic tanks /pits are emptied annually and what volume of sludge is
disposed of at present by looking at actual on-ground practices.
c) Determine the average price per emptying (and accounting for how it may differ based on
volume and containment facility location) that operators are charging.
d) Use the above data to determine as to how many trucks would be needed if septic tanks
were emptied on a three-year basis and design a database for maintaining a register of
containment facilities that are emptied.
e) Create a registration system for private truck operators which permit them to legally empty
septic tanks within the ULB. However, these permits will require that they adhere to safety
and hygiene standards both in emptying and disposal (detailed below), establish certain
regulated tariffs for emptying septic tanks and latrines, and require the use of receipts to
track emptying and disposal. The permits and receipts required for this system are included
in annexures 3, 4, and 5. Pursuant to this, ULBs should establish a system for penalizing
trucks that operate without valid permits/licenses.
f) ULBs should mobilize enough vehicles, either through public or private means, to support a
three- year emptying system. This should be done in line with the growth in demand for
emptying services, so that trucks are not left underutilized.
As section “e,” mentioned previously, truck operators must take the following measures while
• The septic tanks should not be fully emptied; small amount of sludge of around 1 to 2 inches
should be left in the septic tank to facilitate decomposing of incoming faecal waste.
• No fire or flame should be used near the septic tanks as there may be inflammable gases inside
septic tanks.
• Proper safety gear (including uniform, tools, and well-maintained vehicles) must be used by the
operator while desludging/emptying the septic tanks/Pits. The rules under the Prohibition of
Employment as Manual Scavengers and their Rehabilitation Act, 2013 provide for a
comprehensive list of safety gear that should be used while providing these services.
• Operators should clean their surroundings before leaving and after desludging; residents
should not find their homes or surroundings dirtier.
2.1.3 Treatment, Disposal, and Reuse
Treatment: ULBs must not dispose the faecal sludge /septage collected from septic tank/pits
without any treatment and ULBs must comply with CPCB and APPCB norms before disposal of
septage. ULBs should assess the load of septage and assess the requirement of capacity for
treatment plant. ULBs should first try and assess the possibility of setting up faecal sludge treatment
facilities at the solid waste treatment/disposal site or at sewage treatment plants within the city or
utilizing co-treatment, pending the advice and recommendations of the appropriate engineering
authorities. In particular, the state recommends co-locating purpose-built infrastructure, i.e.
building faecal sludge treatment plants next to either sewage treatment plants or solid waste
management plants, in order to gain advantage from synergies in operation and maintenance
(effluent from FSTP can go to STP, or output of FSTP can be co-composted with solid waste, etc.).
Reuse/disposal refers to the methods in which products are ultimately returned to the environment,
as either useful resources or reduced-risk materials. The treated septage can be used as a soil
enricher or as filling material at construction sites. ULB should carry out primary assessment for
availability of market and demand for reuse.
ULBs shall take the following steps in order to properly treat faecal sludge.
a) Operators shall be forbidden by regulation to dispose offsludge collected from the septic
tanks or pits into fields, rivers, nalas, forests, etc. These regulations shall be enforced and
violation shall be subject to advertised financial and/or legal penalties. These penalties
should come into force as soon as there is a sanitary location for dumping faecal sludge.
b) ULB should first assess the possibility of sludge treatment at existing STP in the city or STP
of nearby city through appropriate agreements with STP operators and receiving ULBs. A
list of cities that have STPs is given in Table 1. Some STPs are under construction in different
cities. Proper tests and assessment should be carried out by STP operators before receiving
Faecal sludge/septage.
c) If STP is not available in the city or nearby that can receive the sludge, then ULB should plan
for new faecal sludge treatment facility. Such a new faecal sludge treatment plant should be
designed to cater to expected volumes of septage generated in urban local body and if faecal
waste is expected from nearby rural areas or ULBs.
d) Input quality of the collected septage should be tested at the treatment facility for checking
presence of any metal or traces of industrial waste.
e) The faecal sludge treatment plant should be operational during working hours only and a
responsible person should be appointed in the facility to ensure that no industrial waste is
unloaded in these facilities.
f) Septage should be reused/disposed of only after it meets the parameters in Annexure 6.
Measures to be taken while planning for Faecal Sludge Treatment Plant
Identification of Faecal sludge and septage treatment site is crucial for effective implementation
of septage management plan. Following parameters to be taken into consideration before
finalization of treatment sites:
• Distance of treatment site: Distance from emptying to delivering and accessibility of the
treatment site are major issues. The transport of relatively small faecal sludge volumes on
congested roads over long distances in large urban areas is financially unfeasible. A site that is
too far away implies fewer trips per day, less revenue and more fuel costs to private operators.
• Reliability of electricity: It is also important to assess the availability and reliability of electricity
if treatment technology has mechanical operated parts; as in case of fluctuations it will
increase treatment time and will affect optimal utilization of treatment capacity.
• Neighbourhood: A treatment site may generate objectionable odours. For this reason, it should
be located at an appropriate distance from the residential areas and communities should be
consulted during the process of designating land for a treatment plant.
• Land availability: Projects are often delayed because of non-availability or high price of land.
ULBs should identify the land bank for treatment facility. ULBs should also explore the
possibility of developing faecal sludege and septage treatment facilities near solid waste
dumping sites or already existing sewage treatment plants in order to streamline disposal
processes: effluent from FSTPs may be treated at an STP, and the treated sludge may be cocomposted with solid waste
• Geological Parameters: Assessment of existing geological conditions on site including
groundwater table, type of soil, flooding risk is always recommended to ensure that the
structure can be safely constructed and sludge will not enter the environment through either
porous soil or frequent floods.
2.1.4 Awareness generation and capacity building activities
Awareness generation activities need to be taken up for successful implementation of faecal
sludge management plan. Wherever possible, these activities should be led by City Sanitation Task
Forces, or a sub- committee including members of CSTFs and other interested parties. Where CSTFs
do not exist, ULBs should take efforts to establish CSTFs with particular sub-committees on FSM.
These awareness-building activities are crucial, as ULBs do not have the coercive capacity to force
citizens to comply with FSM regulations; they must be accepted by citizens. Associated training and
capacity building of municipal staff as well as private sector contractors also needs to be taken up.
a) Awareness generation for residents: Members of Resident Welfare Associations,
community organizers, self-help groups and the general public should be sensitized
periodically regarding the need for a safe faecal sludge management system including a 3-
year cycle. The health hazards associated with improper collection and treatment of waste,
and the ill-effects of sewage discharge into fresh water/storm water drains should be
explained to the residents. Sample material for awareness generation is in Annexure 5.
Awareness generation activities should be carried out at the beginning of introducing a
scheduled service in all wards and then repeated periodically over the three-year cycle.
b) Capacity building for municipal staff: Municipal Commissioners, Engineers, Health
Officers, Sanitary Inspectors, and Sanitary Workers should be well trained in safe septage
management and its best practices. This involves regular training sessions on safe
collection, treatment and disposal. Information regarding standard septic tank design, the
need for periodic inspection and desludging of septage, design of a treatment facility,
tender details for engaging licensed transporters, etc. should be disseminated widely to
achieve a safe faecal sludge management system. Training should also be provided on
safety standards.
c) Capacity building for septage transporters/private vendors: Local Bodies should ensure all
safety norms are clearly explained to the septage transporters. Private Operators and
Transporters should be well trained in safe collection and transportation of sewage
including vehicle design, process of desludging, safety gears and safe disposal at the nearest
treatment facility.
d) Gender Inclusivity: It is crucial that municipalities look at faecal sludge management
through a lens considering gender, particularly concerning the empowerment of women and
girls. Women should be equitably involved in the planning of feacal sludge management
activities or the formation of local regulations, and any CSTF or sub-committee that
discusses faecal sludge management should have a membership consisting of at least onethird women, at minimum.
2.1.5 Record-keeping, Reporting, Monitoring and Feedback Systems (MIS)
Record keeping and manifest forms should be an integral part of a comprehensive septage
management program. Recordkeeping requirements should be codified into the law governing the
program. A sample manifest form is detailed out in Annexure 5.
a) The completed document or documents with signatures of the household/property, suction
truck operator, and treatment plant operator should be submitted to the local government
for their records. These documents would validate that the sludge collected from households
is disposed of at proper treatment facilities.
b) A database system such as the one discussed in access and collection will need to be
developed and maintained.
c) Where possible, GIS should be used to be plan the route of suction emptier trucks and track
emptying trucks for regular record keeping.
d) Consumer grievance redressal system for faecal sludge management should also be set up as
a part of urban local body record keeping systems and helpline numbers to be shared with
residents as a part of monitoring and record keeping systems for faecal sludge management.
2.1.6 Private Sector Participation for Septage Management Activities
For effective operationalize of scheduled septic tank emptying service and treatment facilities, ULBs
may also explore the option for private sector participation. Following points to be taken into
consideration by ULB:
a) Explore private sector participation for various activities like procurement, operations and
maintenance of the suction emptier trucks, construction and operations of septage treatment
facility and possible re-users of treated septage within the city as well as in nearby cities.
b) Develop performance based contracts such that payment is linked to the performance of
private sector for providing the services.
3. Financial Resources and Considerations in Faecal Sludge and Septage
While Faecal Sludge and Septage Management treatment options are significantly most cost
effective than conventional sewerage options, they still require capital costs that some
municipalities cannot bear. Most of the initial source of funding across the sanitation value chain
will have to be provided by the joint effort of the central and state government through allied
programme funding like Smart City, AMRUT etc.
Private Funding Options
1. Desludging fee paid by user to the desludging service provider
2. Fine for faulty containment system construction and illegal disposal of faecal sludge.
3. Sale of end products (For Eg. Dried faecal sludge, water).
4. Property tax designated for FSM.
State and Municipal Funding Options
a) As per the Andhra Pradesh Municipal Corporation Act, 1955 – conservancy tax can be
levied on all the properties by the Corporation where city undertakes the collection,
removal and disposal of excrementitiously and polluted matter from privies, urinals and
b) Periodic revisions for the taxes/ charges to be effected based on revisions in costs involved.
c) To the extent possible, revenues should be generated from sale of treated septage for
agriculture or other purposes.
Additional Funding Options
a) ULB may utilize the funds from 14th Finance Commission to implement the various
components related to septage management plan. Creation of database for toilets and septic
tanks, procurement of suction emptier trucks and construction of septage treatment facilities
are the permissible components to utilize the 14th FC funds. The funds would also be provided
as preparatory activity like preparing detailed project report and prefeasibility report for
septage management.
b) IEC & Capacity building funds: IEC funds under SBM can be utilized for various awareness
generating activities. This applies to ULBs using funds to implementing septage management
plan, and can include funding capacity building activities for ULB staff, septage transporters,
treatment plant operators, and ULB residents.
c) Convergence with existing schemes/activity: ULBs can ask for funds under the existing state
and national schemes such as Smart City Mission AMRUT
d) Corporate Social Responsibility: ULBs can also raise funding through Corporate Social
4. Technology Options for Septage Management
Treatment options for faecal sludge /septage are based on four treatment objectives. These four
mechanism enable sludge to be handled, disposed of, and/or re-used safely.
1. Solid liquid separation: Solid-liquid separation is the first step for successful treatment
of feacal sludge, as refuse must be brought to some sort of uniform consistency.
2. Dewatering: Before treatment, faecal sludge is over 80-90% water by volume; de-watering
is necessary to reduce volume/weight and destroy the habitat that allows dangerous
pathogens to grow.
3. Stabilization: Stabilization refers to several biological and chemical processes
through which ongoing biological-chemical reactions run their course and nutrients
are consumed by bacteria.
4. Reuse applications: Once the previous three steps have been accomplished, sludge can be
re-used for productive purposes or sent on for further treatment (such as co-composting
with solid waste) depending on its chemical/biological profile.
Septage containment and treatment technology options are included according to Swachh
Bharat Mission Guidelines in the following table. In any given context, the technology choice for
conveyance system generally depends on the following factors:
• Type and quantity of products to be transported
• Distance from containment facilities
• Accessibility
• Topography
• Soil and groundwater characteristics
• Financial resources
• Availability of a service provider
• Management considerations
Technologies for Faecal Sludge management based on the above objectives can be adopted as
mentioned in Table 2.
Urban Local Bodies can choose from a range of treatment options available in the market,
depending upon their needs and available finances.

Annexure 1: Septic Tank Specifications, Guidelines, and Designs
Depending on the geography, soil condition, water seepage capacity of the soil the design can
be prepared and approved by the Local Bodies. Proper septic tank design considers the
following factors:
• Sized properly with appropriate sludge detention time, volume and hydraulic
• retention time
• Proper inlet and outlet structures
• At least one baffle separating the tank into multiplecompartments
• Water tight
• Access port for each compartment that allows for inspection andpumping

above the height of the highest building within 20 meters
Improved Septic Tank” - the walls of the conventional septic tank
can be replaced with baffle walls to have a multi chambered
baffled septic tank. The paper states “This movement of
wastewater inside the tank helps in creating the turbulent flow
which causes enhanced mixing of the raw sewage with already
existing activated sludge and accelerates the decomposition of the
solids because of intensive contact between
the activated sludge and fresh influent”.

For dewatered septage/sludge can be used as fertilizer in agriculture application, it
should satisfy the following criteria of Class A Bio-solids of US EPA: A faecal coliform
density of less than 1000 MPN/g total dry solids, Salmonella sp. density of less than 3
MPN per 4 g of total dry solids. WHO (2006) suggests Helminth egg concentration of 1/g total solids and E coli of 1000/g total solids in treated septage for use in agriculture
MSW Rules (2000) recommended the quality for compost as referred to Table below.
In the absence of any standards, it is recommended that these be adopted until such
time standards are notified by the Central Pollution Control Board.
Properly treated sludge can be reused to reclaim parched land by application as soil
conditioner, and/or as a fertilizer. Deteriorated land areas, which cannot support the
plant vegetation due to lack of nutrients, soil organic matter, low pH and low water
holding capacity, can be reclaimed and improved by the application of treated septage.
Septage sludge, as a result of lime stabilization has pH buffering capacity that is
beneficial for the reclamation of acidic soils. Treated septage contains nutrients in
considerable amounts, which supports the growth of a number of plants.
Drip irrigation is the preferred irrigation method for settled septage effluent when
irrigation is feasible. Crops which could be safely grown are corn, fodder, cotton, trees
including fruit trees, eucalyptus and poplar.
Aquaculture can be practiced for settled septage effluent when freshwater is
available to achieve dilution to ensure dissolved oxygen is above 4 mg / l. Fish species of
tilapia and carp are preferred since they tolerate low dissolved oxygen. Both drip
irrigation and aquaculture need land and are feasible at city outskirts.
