Storm water design - rainfall data and runoff-routing models?

Hi, I am an environmental engineer from Australia looking at a project in Hyderabad and am just commencing some research on design standards and design approaches for stormwater drainage design.

I have found a few bits and pieces through this portal - RWH Manual as well as some information from Venkata Rathnam et al.

I understand the use of LID, SUSD approaches to drainage design - in Australia known as Water Sensitive Urban Design (WSUD) and the importance of rainwater harvesting to reduce pressure on groundwater resources along with other benefits.

A common approach here in Australia, is, during the conceptual phase of design, to use some modelling software known as the Model for Urban Stormwater Improvement Conceptualisation (MUSIC) as a tool to conceptually design and test a range of stormwater management measures (tanks, ponds, filtration, wetlands, biofiltration, swales etc).  This software uses a continuous simulation down to 6min time steps (if you have the data) to assess what impact measures have on stormwater quality (TN, TP and TSS) as well as volume.  I am fairly confident in being able to apply this software to an Indian context - as long as I can chase down some continuous (6min timestep) rainfall data, or at worst daily rainfall data, and possibly pollutant generation rates for various land uses (although this may be harder).

Two questions follow:

Where would I find rainfall data for the Hyderabad area - and what are my chances of being able to get hold of continuous (6min) data?

Are there any particular desing standards for pollutant concentration reduction in stormwater runoff, or reductions in runoff volume?

Moving from conceptual design, to the detailed design of the stormwater network presents more issues.  In Australia I am able to make use of a range of runoff routing models (SWMM, RAFTS, DRAINS) to assist with designing the stormwater network for various design storms (1 in 5yr, 1 in 100 yr etc).  Are there modelling programs out there that are adjusted to indian conditions to assist with drainage network design (pipes, overland flow paths, basins)?

My questions are:

Where would I find design standards for stormwater drainage design - are there specific design events to be catered for in the Hyderabad area - what is the best place to start looking for these?

Has modeling software been developed for stormwater drainage design for the Indian context?

I understand that these are big questions and am not expecting hugely detailed answers given that peoples time is valuable. However, any assistance on the above would be greatly appreciated.





1. Dear Member,1.  For getting

Dear Member,

1.  For getting Rainfall data, you may approach IMD, Pune, HMWSSB and PWD.

2.  A couple of years back a program called APUSP was taken up in Andhrapradesh wherein for a number of towns / cities  Drainage System studies were taken up. Design standards were evolved and a manual was also available. May contact HMWSSB / PWD to get further details.

3.  In my knowledge there is no specific software developed in the Indian context. Usually the local consultants develop their own Excel based spreadsheets which are widely used or they use the internationally accepted commercial software. In my view any commercial software well developed, can be utilised in the Indian context as well as the fundamentals are same.

4.  For the design standards for pollutant concentration reduction in stormwater runoff.  Please contact State Pollution Control board.

Hope you have answers for all the queries raised.

2. Dear Member,About a year

Dear Member,

About a year back, there was a BIS attempt to prepare a Storm Water Manual. But, unfortunately, there is not much progress in the work. Still some aspects of the design standards would be available in the relevant BIS codes.
Runoff routing models (SWMM, RAFTS, DRAINS) that are being used by you should work for Indian conditions too if one chooses the parameters suitably and makes suitable changes/adjustments.
You should be able to get rainfall data from the Indian Meteorological Department.

Wish you good luck in all your attempts towards this task.

3. As regards rainfall data, you

As regards rainfall data, you can get the data from the Hydrology Data Users Group (Hyderabad) by becoming a member. You will be able to access data of Standard Rain Gauge stations, Upgraded SRG Stations, Full Climatic stations, Gauge & Discharge stations, Digital Water Level Recorder stations, Water Quality sampling sites and Sedimentation sites. SRG readings should be available from 1980 onwards. They do have continuous rainfall data as they use autographic rain gauges but I am not sure if they sell it. You will have to contact the Superintending Engineer, Hydrology Project Circle, Hyderabad for this. The address is - H. No. 6-2-916/1, Chintal Basti, Khairatabad, Hyderabad -500004, ph num - 040-23378907 and email is or




4. Dear Mr Bain1. For rainfall

Dear Mr Bain

1. For rainfall data approach the local division of India Meteorological department, Hyderabad (check They can provide you short duration rainfall data, but 6 min is too optimistic, mostly you will get at 15 mins interval, or hourly data

At present there is no separate guideline for urban drainage design in India. The sewerage manual published by Central Public Health Engineering and Environmental Organisation, devotes a few sections on storm drainage design. This manual does not specify any standard for pollutant reduction in stormwater. Also there is no design guidleine for offline or online stormwater flow attenuation system. You can also have a look at the very recently published

You may also get in touch with Professor Kapil Gupta of Indian Institute of Technology, Mumbai . He is a Member, Expert Committee for drafting Manual on Urban Drainage, Ministry of Urban Development, Government of India and can advise you regarding modelling. He has a vast experience of stormwater modelling in the Indian Scenario.   

2. For detailed design standards like storm frequency to be adopted, derivation of the IDF curves, estimation of run-off etc. you can refer to the CPHEEO manual (only 18 year old) mentioned above. You can also have a look at IRC SP 50 and SP 42.

We used the MOUSE modeling software (in combination with MIKE 1) by DHI for verification the detailed design of the stormwater draiange system in Kolkata in Eastern India (a city much bigger than Hyderabad), a few years back. However, this was mainly for verification of whatever we designed using typical spreadhseets. Indian municipalities generally do not believe in stormwater modelling much. Hope you get a logical client :)

5. Thanks very much to all the

Thanks very much to all the responses.  Very timely and very helpful.

Am looking forward to the possible work, and am hoping for an innovative outcome, so - if possible - I will provide some sort of feedback on how I go.

7. Dear Mr. Bain . For Rain Water Harvesting at Hyderabad

Dear Mr. Bain,

             With regard to the information that you need for your project design you can have instant information from a number of organisations located right in the Hyderabad city itself. The data on major components of Hydrological cycle active over Hyderabad city can be obtained from APSGWD, APSTRAC,NRSA, NGRI,CGWD,Dept.of Irrigation,GHMC, HWWC, AP Dept. of Pollution & Environment, AP Industrial Infracstructure Corporation, ICRISAT,Indian Meteorological Department.

     With regard to the construction and design of the water Harvesting structures the expertise is with Dept. of Rural Development, Dept. of Irrigation., etc.

      The best way is to make a a local expert Hydrogeologist as an associate , who can help to collect information for you as you require.

8. Reg: Rainfall runoff data of Rajasthan


I'm a Water systems professional currently working with water modelling as part of a student project. It is related to the groundwater of Rajasthan and in particular related to the areas surrounding Jaipur, and to carry out this I need data on day to day basis, recorded locally. I was able  to obtain information regarding precipitation, temperature and other related meteorological data. But, I couldn't find data related to rainfall runoff or ground water discharge on day to day basis. Can some one please suggest any sources to obtain these data.

Thank you for your time.


9. Hello Mr Bain

Hello Mr Bain

I am Nivedita Gogate, working on sustainable stormwater management in India. My case study area is Pune. Are you based in Australia or in India? As far as I know, in India we do not use any modelling software for stormwater. Mostly, rational method has been used for design. Prof Kapil Gupta from IIT, Bombay has used a software. I would like to discuss a few aspects with you, if you wish. You may contact me at: Or, alternatively, can you send me your contact details.

Thanks and Best Regards

Nivedita Gogate
