The extent to which households in the city are connected to the water supply network with a direct service connection, as percentage of total number of households. Household level water supply connection i.e. direct piped connection, is the minimum acceptable standard for water supply service. Water provision through public stand posts or tankers is not considered as an acceptable longterm service provision standard. SLBs for Urban Services developed by the MoUD provide guidance on the service levels for water supply.

• This will include households which receive municipal water supply at one common point, from where it is stored and distributed for all households (for e.g. as in apartment complexes).
• This will include households which receive municipal water supply at one common point, from where it is stored and distributed for all households (for e.g. as in apartment complexes).
• Households supplied water through public stand posts or tankers should be excluded. Households completely dependent on other water sources such as bore wells, open wells, etc. should not be included.
• Data on number of connections can be obtained from the records available with ULB/ Water Utility or Public Health and Engineering Department (PHED), as applicable.
• Data on households can be obtained from the decennial Census of India. Past census figures should be used as base, and annual growth rate should then be used to arrive at current population.

Per capita water supplied, indicates the adequacy of the municipal water supply system to source adequate raw water, treat water to potable standards and supply the same into the distribution system. This denotes the overall sufficiency of water supplied into the municipal network to meet the needs of the population. SLBs for Urban Services developed by the MoUD provide guidance on the service levels for water supply.

• Data on average quantum of treated water supplied into the distribution system on a daily basis, obtained on the basis of measurement by bulk flow meters at the outlet of treatment plants and/or bulk production points, can be obtained from the records of ULB/ Water Utility or PHED, as applicable.
• If water is distributed from multiple points, aggregate of that quantity should be considered as total quantity of water supplied into the distribution system. However, the quantum should exclude all bulk transmission losses, as measured through water audit data available with ULBs
• Population data can be obtained from the decennial Census of India. Past census figures should be used as base, and annual growth rate should then be used to arrive at current population.

This denotes the quality of water supplied to citizens, as per specified potable water standards. This is an important aspect, since poor water quality can pose serious public health hazards. Quality standards for potable water are laid down by the Central Public Health and Environmental Engineering Organization (CPHEEO) as part of the Manual on Water Supply and Treatment, 1999.

• Potable water standards for measurement and sampling regimen should be as per standards and norms laid down by CPHEEO (Manual on Water Supply and Treatment, 1999).
• Samples should be drawn both at the treatment plant outlet as well as at the consumer end.
• Sample survey as per sampling regimen prescribed by CPHEEO (Manual on Water Supply and Treatment, 1999)
• All parameters of the quality standards should be met. Even if one standard is not met, the sample cannot be assumed to have met the standards

This denotes the quantity of water produced and supplied by the ULB that does not earn the utility any revenue. NRW comprises of - a) consumption which is authorized but not billed, such as public stand posts; b) apparent losses such as illegal water connections, water theft and metering inaccuracies; and c) real losses due to leakages in the transmission and distribution networks. SLBs for Urban Services developed by the MoUD provide guidance on the service levels for water supply.

• Data on average quantum of treated water supplied into the distribution system on a daily basis obtained on the basis of measurement by bulk flow meters at the outlet of treatment plants and/or bulk production points, can be obtained from the records of ULB/ Water Utility or PHED, as applicable.
• If water is distributed from multiple points, aggregate of that quantity should be considered. However, the quantum should exclude all bulk transmission losses, as measured through water audit data available with ULBs
• Data on quantum of water sold can be obtained from the records of the ULB/ Water Utility or PHED, as applicable
• Where full metering has been achieved the actual aggregate volume of water consumed based on which consumers have been billed should be considered for computation.
• In the absence of metered connections and flat water charges, the volume of water supplied to such consumers can be calculated on the basis of average consumption per consumer and the total number of such consumers.

The extent to which water supply connections in the city are covered through functional meters (including smart meters), thereby facilitating better monitoring, volumetric billing and reduction in losses. SLBs for Urban Services developed by the MoUD provide guidance on the service levels for water supply.

• Total number of metered connections will include metered direct service connections, as well as metered public stand posts.
• Total number of metered connections will include metered direct service connections, as well as metered public stand posts.
• Households and establishments which receive municipal water supply at one common point, from where it can be stored and distributed for all households (for e.g. as in apartment complexes), should be included.
• Households that are completely dependent on other water sources such as bore wells, open wells, tankers etc. should not be included.
• Data can be obtained from the records of the ULB/ Water Utility or PHED, as applicable.

The extent to which individual plots within a city have the ability to retain storm water within the site through rain water harvesting (RWH) structures. The MoUD under the AMRUT Mission has recommended that all new developments/ redevelopments with minimum plot size of 300 sq.m., and all commercial and public buildings should have rainwater harvesting facilities.

• Only those buildings where ULB has a record that such facilities have been constructed should be considered.
• Data can be obtained from the records of planning or building sanctions department of the ULB.
