Frequently Asked Questions
Planning & Project Formulation
(i) the used water flowing in open drains (or storm water drains), and
(ii) the faecal sludge/septage emptied periodically from single pits/septic tanks. Used water in drains may comprise of either grey water (the non-toilet discharge, where toilets are connected to single/twin pits or septic tanks with soak pits) or grey water mixed with overflows/effluent from septic tanks. The drain may also contain other kinds of water like storm water, industrial effluent or black water (in case, the toilets are directly connected to drains). A small number of ULBs do not discharge any used water into drains as households have soak pits for both toilet and non-toilet discharge. Such ULBs only generate faecal sludge.
1. Understand the current scenario of sanitation, for which one needs to review available data across the sanitation chain and collect primary data from an appropriate sample. To understand what data to collect and how, please refer to baseline and data collection section under stage 1
2. Identify and analyse existing sanitation/UWM infrastructure (water supply systems, Toilet typology, desludging trucks, STP/FSTP capacity, drain end points etc.)
3. Evaluate present and future demand for UWM infrastructure
4. Identify gaps to propose appropriate interventions to meet the demand of projected population
1. Implementation of Sewage Treatment Plants (STPs), with provision of co-treatment, to expand used water and faecal sludge treatment capacity. This helps strengthen used water management of the ULBs, supporting SBM-U 2.0’s vision of a Water-Secure Urban India.
2. In case the ULB is not able to arrange funds for sewerage network, as an interim solution, funding for interception and diversion (I&D) systems is available. These systems are designed to capture and redirect used water flowing in storm water drains, that would otherwise flow untreated into natural drains and/or water bodies. By channelling this used water toward sewage treatment plants (STPs), cities can significantly reduce pollution of water bodies and enhance water quality.
3. The third is desludging equipment, which plays a crucial role in improving faecal sludge and septage management (FSSM). Regular emptying of septic tanks, using these equipment helps prevent untreated used water and faecal sludge from contaminating the environment. ULBs can also use these funds to procure Personal Protective Equipment (PPE) to ensure safety of desludging operators. States and cities are encouraged to augment the funds available under SBM with additional funds to achieve UWM objectives.
• Interception & Diversion (I&D) - The average cost considered for I&D works is Rs.50-60 lakh per kilometre. This cost may increase in towns with catchment population more than 75,000.
• Sewage Treatment Plant (STP) - The cost ranges from 1.2 crores/MLD to 1.8 crores/MLD depending on the capacity of the plant and the technology selected.
• Desludging Vehicles - Standard rates from GeM (Government e-Marketplace) portal can be considered.
• Faecal Sludge Treatment Plant (FSTP) – The cost ranges from 2.5 lakhs/KLD to 7 lakhs/KLD depending on the capacity of the plant. The final cost of the components should be finalized based on the prevailing Schedule of Rates (SOR).
DPR Preparation
• Baseline Assessment- Data collection & analysis, Population, Used water generation, existing toilet and containment infrastructure, sewerage coverage, drainage system status, effluent discharge points, existing infrastructure with capacity and year of completion, ongoing projects with capacity and year of completion
• Population projection
• Gap Analysis – management of black water, grey water and faecal sludge
• Land availability
• Possible conveyance and treatment options
• Proposed Solution & Technology based on Life Cycle Cost Analysis
• Project Components & Design – Design methodology, design period, design of various components
• Cost Estimates - BOQ of individual components
• Implementation Strategy
• Detailed Operation & Maintenance plan for 5 years with specific details on the different revenue streams.
• Many ULBs do not yet have a sewer network or complete coverage with storm water drainage, and designing an STP for 100% of the projected population could result in inefficient utilisation of funds.
• To ensure that at-least 70% of the populations’ used water is treated
• To ensure that used water that can be efficiently collected, is treated
• Based on core zone concept when the network is provided to high density area(s), coverage in 30% of the area will be able to cater to 70% population
However, if a ULB already has a sewer or storm water drains network and it is expected that used water collection efficiency and plant utilization will be optimal, then the STP can be designed for 100% of the projected population as well.
Procurement and implementation
The state may also make it mandatory for bidders of larger projects (generally in larger towns of the state) to also take up a cluster of projects in small towns.
Planning - Smart Data collection - Smart Data collection and analysis – GIS mapping, topographic survey
Designing - Project formulation and DPR development
Implementation - Construction of infrastructure (Public private partnerships for used water treatment)
Operation - Operation and maintenance of conveyance structure, STPs and desludging equipment
Financing - Bank loans for CapEx, Corporate Social Responsibility (CSR) funding for certain component of used water management
Monitoring - IoT based monitoring of systems
Re-use - Potential buyers (industries) for treated water and bio-solids

Note: Not all SKPs can deliver training programs in all subjects, states should do their due diligence in selecting SPKs. And hire agencies based on their areas of expertise.
Financing & operating models
1) For Union Territories (UTs without legislature): 100% funded by the Central Government.
2) For UTs with legislature: 100% Central funding for UT share, with additional contributions from ULBs if required.
3) For North-Eastern and Himalayan States: 90% by the Centre and 10% by the State/Urban Local Bodies (ULBs).
4) For Other States: 50% by the Centre, 30% by the State, and 20% by ULBs or other sources.
1) Build-Operate-Transfer (BOT): The private sector builds the treatment infrastructure, operates it for a fixed period, and later transfers ownership to the Government.
2) Design-Build-Operate (DBO): The private partner is responsible for the design, construction, and operation of the facility for a pre-defined period, while the ownership remains with the government.
3) Performance-based contracts: The private player is paid based on performance indicators like effluent quality, cost savings, or plant efficiency.
4) Hybrid Annuity Model: The government provides an upfront payment (e.g., 40%) during the construction phase, while the private partner raises the remaining funds and is paid back over time via annuities.
There can be other models like service contracts where Government contracts a private firm for specific services like O&M. The private entity can also lease an existing treatment facility to operate and earn revenue from user fees.
Procedure for Fund Release
• State Government Designates a Single Nodal Agency (SNA) for each State Linked Scheme (SLS).
• SNA opens dedicated accounts in RBI for the project.
• The Ministry of Government of India releases funds directly into these accounts based on project needs and compliance.
• Payments to vendors/beneficiaries are made through State IFMIS and PFMS, ensuring real-time fund transfer without delays.
1) Pumping stations
2) Screens (for debris and solid waste removal)
3) Gates (sluice gates, flap gates, etc.)
4) Civil infrastructure costs, including:
_Construction of weirs
_ Pipelines/Open channels for diverting used water to treatment facilities
These components are covered to ensure effective used water management and prevent untreated sewage from flowing into environment.
However an I&D arrangement which can be used as trunk sewer at a later stage can be funded under SBM (provided the cost of I&D structure doesn’t exceed 15% of the cost of laying sewers across the town).
