Lucknow Nagar Nigam GPR Survey for Road Cuts and Sewers
Jal Kal sewers, LESA feeders and Green Gas lines charted under corporation streets, from Chowk and Aminabad out to the newer wards.
Quick AnswerA Lucknow Nagar Nigam GPR survey shows which buried lines under a corporation street belong to Jal Kal, LESA, Green Gas or a telecom operator, and how deep each lies. The sheet counts most in the old-city lanes on the East–West metro alignment. When ground penetrating radar (GPR) wins and when a locator does is the subject of more on Underground Utility Detection Methods.
What does a Lucknow Nagar Nigam utility survey deliver?
A single sheet listing each pipe, cable and duct beneath the street with its likely depth and owner. A ground penetrating radar survey produces it so the next trench, bore or drain can be routed around those utility lines. The sheet serves road-cut applications, design and tender packages, and the contractor's dig plan on the day.
Lucknow's civic body began as a Municipal Board in 1884; its 110 wards now come under the Uttar Pradesh Municipal Corporation Act of 1959. Its Jal Kal wing handles water supply and sewerage, so one body may own both the pipe you are replacing and the one beside it. Everything else under the road belongs to other owners.
Who owns what under a Lucknow road?
Expect four or five owners on any main road, each with its own records and its own office.
| Under a Lucknow road | Normally answerable | Our drawing shows |
|---|---|---|
| Drinking-water mains and sewers | Jal Kal wing of the Nagar Nigam | Line, each manhole, likely depth |
| Stormwater drains | The Nagar Nigam, or whoever owns the road | Drain route, outfall points, culverts |
| Feeders, 11 kV and low tension | Lucknow Electricity Supply Administration (Madhyanchal discom) | Feeder routes, joints, where they cross |
| City gas | Green Gas Ltd | Marker posts, crossing depths |
| Fibre and telecom ducts | Whichever operator laid them | Duct groups and their pits |
Table note: roads in development authority schemes may still be with LDA; see our LDA Lucknow utility survey team for that side.
What will the East–West metro mean for old Lucknow streets?
Months of utility diversion along some of the most crowded roads in the city, starting with accurate maps of what is already there. The Lucknow Metro East–West corridor from Charbagh to Vasant Kunj, about 11.2 km long, received central approval in August 2025. Close to 6.9 km of it runs underground, with stations planned at Charbagh, Gautam Buddha Marg, Aminabad, Pandeyganj, City Railway Station, Medical College and Chowk.
The tunnels pass well below the services, but station boxes and entries are dug from the surface, and every main, sewer and cable inside those footprints must move first. Roads in Aminabad and Chowk carry generations of replaced and abandoned pipes. A survey here records disused lines as well as live ones, because a dead pipe still has to be dug out.
How does Gomti ground affect the scan?
Lucknow stands on deep alluvium of the Gomti plain, which is easy to dig but variable for radar. GPR sends electromagnetic waves downward and reads the echoes from buried objects, and dry sand lets those waves reach well below the sewers. Near the Gomti, silty clay, waterlogged colonies and seepage from ageing mains cut that reach. Each site opens with a test pass, and the sheet records the depth the GPR data reached. Crew set-up for the city is explained under details of GPR survey in Lucknow.
Where radar falls short, the locator takes over for metallic lines and lifted covers give measured sewer depths. Where a plastic pipe sits in wet clay, the report asks the contractor for a trial hole.
Why do cable crossings get special attention?
Because a cut 11 kV cable stops work, darkens a neighbourhood and can injure the person holding the shovel. Many Lucknow roads carry power, street lighting and several telecom cables in a narrow strip under the footpath. Utility locating starts with each energised cable, then a high frequency radar antenna crosses the strip for the unpowered ones, and every crossing is marked on the road. Our cable workflow is explained under what we do: underground cable detection.
Where does the survey sit in a road-cut file?
Before submission, so the file shows the services the cut will cross. Rules, fees and restoration charges are set by the Nagar Nigam and change over time. Permissions and site habits are summarised in Mezux: utility survey guide for Lucknow. True coordinates, when the file needs them, come from control set by a DGPS survey for Lucknow sites.
What does a Lucknow survey cost?
Metres scanned drive the price; there is a floor per project and lower slabs for big programmes.
- Standard GPR scan: ₹24 per metre
- L-section with depth profile: ₹32 per metre
- Minimum order: ₹1,00,000 per project
- Whole-order discount: 25% above 100 km, 40% above 500 km, 50% above 1,000 km
A 6 km drainage scheme scanned at the standard rate is ₹1,44,000. Three small lanes totalling 1.2 km do not reach the threshold, so ₹1,00,000 applies. GST is extra. One of our own engineers is based in Lucknow, so a morning order is often scanned that afternoon. No order waits more than a single working day, and any travel charge is named in the written quote.
What should you send before the scan starts?
A route, a purpose and whatever records you have. A KMZ, a marked-up PDF or a Google pin is enough to scope the job. It helps to state the trench width and road hours, attach any Jal Kal, LESA or operator sheets, and name the person who can lift covers. Say who will read the utility data: a zone office, a design consultant or a gang starting next week. Where no records exist, we widen the scanned band and price it in.
How do we tie lines to the metro alignment?
Diversion drawings for the East–West corridor, one of the largest construction projects in the old city, are checked against the metro's own chainage. We bring in coordinates through DGPS control in Lucknow at open spots such as the Charbagh forecourt. A total station into Aminabad and Chowk lanes then carries them where buildings block the sky, recording shop fronts, covers and road levels. Radar lines join the same frame, and Jal Kal sewer inverts are levelled for any sewer that must drop beneath a station box.
Who scans Nagar Nigam roads in Lucknow?
Mezux Touch itself, in utility survey since 2003, with 58 GPR systems it owns and engineers it pays. Site work stays in-house under ISO 45001, 14001 and 9001. Work orders have come from Lucknow Nagar Nigam directly. They also come from the builders of its drains and roads, the consultants who design them and the service agencies sharing its streets. For Lucknow utility mapping, send the route and its purpose to price your Lucknow job.
Frequently asked questions
Does Jal Kal give out sewer drawings?
Records can sometimes be obtained through the contractor or consultant on a Nagar Nigam work. We use them as a guide, and the final drawing rests on what we find.
Can you tell a live pipe from an abandoned one?
Not always by radar alone. We check connections at chambers, trace metal pipes with the locator and mark doubtful lines as unconfirmed.
Can you help on an East–West metro diversion contract?
Yes. Package contractors and consultants on metro diversions hire us for mapping underground lines to be shifted, station by station.
How quickly can you start?
Right away in most cases. The longest gap between order and first radar pass is one working day, as our engineer is local. Chargeable travel is billed on its own line.
Which parts of the city do you cover?
All wards and the outer areas. Coverage details: our page on survey coverage in Lucknow.
Is a short lane worth surveying?
If it carries cables or a gas line, yes. Grouping lanes into one order spreads the floor charge.
