In Short
Commercial plumbing is judged on gradients and pressure testing, not on fittings. Impulse Branding Solutions installs hot and cold water supply, soil, waste and vent drainage laid to Indian Plumbing Code gradients, washroom fit-outs with sanitaryware and waterproofing, kitchen and pantry plumbing, water treatment sized to occupancy, and STP and ETP integration to CPCB norms.
Plumbing rarely fails at handover. It fails months later, as a ceiling stain two floors down, a washroom that never quite drains, or a smell nobody can locate that turns out to be a vent line that was never properly connected. Almost all of it traces back to two things: gradient and testing. A drainage line laid to the wrong fall will work when the building is empty and stop working when it is occupied, and a line that was never hydrotested before the screed went down cannot be inspected without breaking the floor. IBS treats pipe-slope discipline and pre-closure testing as the substance of the package rather than as a formality at the end of it. Supply, drainage, and treatment are handled as one coordinated scope by the same in-house team, so the fall of a waste line and the position of the fixture it serves are decided together rather than negotiated between two contractors after the wall is built.
What We Make
What does IBS's plumbing scope cover?
Treatment infrastructure is being built at scale. Under the Namami Gange Programme, ₹16,025.97 Crore of the ₹21,340 Crore disbursed by 15 March 2026 had gone to sewage treatment projects, against a target of 7,000 MLD of cumulative treatment capacity by December 2026 (IBEF, 2026). Buildings discharging into that network carry their own obligations, which is why STP and ETP integration now sits inside a commercial plumbing scope rather than beside it. Below is what each part of the IBS plumbing scope covers.
General Contracting · Type 01
Water Supply Systems
Hot and cold supply from the source or tank down to the fixture, sized to the occupancy the building will actually carry rather than to the fixture count alone.
- Hot and cold supply lines: sized to demand and pressure-tested before commissioning
- Pump and pressure systems: booster and hydro-pneumatic arrangements specified to the head required at the highest fixture
- Tank connections and distribution: overhead and underground tank connections, with isolation valves positioned for maintenance rather than for convenience during installation
General Contracting · Type 02
Drainage, Soil, Waste & Vent Systems
The part of a plumbing installation where gradient decides whether it works, and where a mistake is invisible until the building is occupied.
- Soil, waste and vent lines: laid to Indian Plumbing Code gradients rather than to whatever fall the ceiling void allows
- Vent line design: properly connected venting, because trap seal loss is the usual cause of a smell nobody can locate
- Rainwater and terrace drainage: outlets and downtakes sized to the catchment area
- Access and rodding points: positioned so a future blockage can be cleared without opening a finished ceiling
General Contracting · Type 03
Washroom & Sanitary Fit-Outs
Complete washroom delivery including the waterproofing underneath it, which is the layer that decides whether the floor below stays dry.
- Sanitaryware supply and installation: fixtures set out against the approved layout, with the brand agreed at GFC stage
- Cubicle systems and partitions: installed to the setting-out drawing rather than adjusted on site
- Waterproofing: applied and ponding-tested before tiling, since retrofitting waterproofing means removing the finish above it
- Accessible washrooms: clearances, grab rail positions, and fixture heights detailed to the accessibility brief
General Contracting · Type 04
Kitchen, Pantry & F&B Plumbing
Commercial kitchen and pantry plumbing, where the drainage carries grease and solids that ordinary sanitary drainage is not designed for.
- Grease trap and interceptor provisions: sized and positioned to the kitchen's output, with access for servicing
- Equipment connections: supply and drainage points coordinated with the kitchen equipment vendor's layout
- Floor gullies and washdown drainage: falls set for a floor that gets hosed rather than mopped
General Contracting · Type 05
Water Treatment Systems
Treatment sized to the building's actual water quality and occupancy rather than to a standard package, because incoming water varies substantially between locations.
- Water softeners: sized against measured hardness rather than an assumed figure
- Filtration and RO systems: specified to the incoming water analysis and the intended use
- Storage and recirculation: arrangements that avoid stagnation in low-use branches
General Contracting · Type 06
STP & ETP Integration
Sewage and effluent treatment works for buildings required to treat on site, executed to the discharge standards the regulator sets rather than to a generic specification.
- STP integration: sewage treatment works coordinated with the building's drainage design
- ETP integration: effluent treatment where the building's discharge requires it
- CPCB and State Pollution Control Board norms: discharge parameters worked to the applicable consent conditions
- Treated water reuse: recirculation for flushing and landscape use where the design provides for it
Specification
What codes and testing standards does IBS work to?
Plumbing is judged on two things that are both invisible at handover: whether the gradients are right and whether the lines were tested before they were buried. These are the codes IBS designs to and the tests carried out before any finish closes over the work.
Design & compliance codes
- Indian Plumbing Code (IPC): pipe sizing, gradient, and sanitation standards for supply, drainage, and venting
- National Building Code (NBC) 2016: Part 8 for building services, applied alongside the fire strategy where plumbing crosses compartmentation
- CPCB and State Pollution Control Board norms: discharge parameters and consent conditions for STP and ETP works
- Accessibility brief: fixture heights, clearances, and grab rail positions in accessible washrooms detailed to the project's brief
Materials & specification
- Pipe material by application: supply, drainage, and vent materials selected per service rather than one material used throughout
- Brand specified at GFC: sanitaryware, fittings, and pipe brands agreed at Good For Construction stage and confirmed at order, with substitution requiring written approval
- Valve and access positioning: isolation valves and access points positioned for future maintenance rather than for ease of installation
- Waterproofing systems: specified to the wet area and ponding-tested before the finish is applied
Testing before closure
- Hydrotesting: every supply and drainage line pressure-tested before flooring and ceiling close, not sampled afterwards
- Ponding tests: wet-area waterproofing flood-tested and held before tiling
- Gradient verification: drainage falls checked against the design before lines are covered
- Test certificates at handover: results recorded per line and issued as part of the as-built record

How We Deliver
From brief to handover.
A plumbing package is largely finished before anyone can see it, which is why the order of work matters more here than on most disciplines. These are the stages IBS works through.
Site survey and water assessment
Existing supply, tank arrangement, drainage invert levels, and available fall surveyed, with incoming water quality established where treatment is in scope, since softener and filtration sizing depends on measured hardness rather than an assumed figure.
Design and GFC drawings
Supply, drainage, and vent design produced against Indian Plumbing Code gradients, with fixture positions coordinated against the interior layout and the available fall checked before the layout is frozen.
Coordination with other services
Drainage runs, cable trays, duct routes, and sprinkler layouts coordinated in the ceiling void at drawing stage, because drainage has the least flexibility of the four and should be routed first.
First fix and concealed pipework
Concealed supply, drainage, and vent pipework installed, with gradients verified against the design before anything is covered.
Hydrotesting and waterproofing
Every supply and drainage line hydrotested, and wet-area waterproofing applied and ponding-tested, before flooring or ceiling closes over the work.
Second fix and fixture installation
Sanitaryware, fittings, cubicles, and kitchen equipment connections installed against the approved setting-out drawing.
Commissioning, documentation, and handover
Systems flushed and commissioned, treatment plant performance verified where in scope, and test certificates and as-built drawings issued as part of the handover file.
Why Buyers Choose IBS
Built in-house. Owned outright.
Plumbing is the discipline where the cheapest quotation and the most expensive outcome correlate most reliably, because almost everything that matters is buried before anyone can inspect it. These are the parts of the IBS model that decide the outcome.
01
Tested before the floor closes
Every supply and drainage line is hydrotested before flooring and ceiling close. A leak found at that point costs a joint. The same leak found after handover costs the screed, the finish, and usually the ceiling of the floor below. This is the single most consequential sequencing decision on a plumbing package and it is the one most often compressed when a programme tightens.
02
Gradient treated as design, not as site judgement
Drainage falls are set against Indian Plumbing Code gradients at drawing stage and verified before lines are covered. A line laid to whatever fall the ceiling void happened to allow will work in an empty building and stop working in an occupied one, which is why the failure surfaces months after the contractor has left.
03
Supply, drainage, and treatment as one scope
The same in-house team handles supply, drainage, and treatment, so the fall of a waste line and the position of the fixture it serves are decided together. Splitting these across contractors is how a fixture ends up in a position the drainage cannot serve without a pump nobody budgeted for.
04
Waterproofing owned by the same contractor
Wet-area waterproofing is applied and ponding-tested by the same team that installs the plumbing, rather than left to the civil contractor and inspected by nobody. Retrofitting waterproofing means removing every finish above it, which is why it is tested and held before tiling starts.
05
Standalone plumbing, or integrated with the fit-out
Plumbing can be taken as a standalone package where a civil contractor is already appointed. On a full IBS fit-out it sits under the same project lead as electrical, HVAC, fire safety, and civil works, so a clash between a drainage run and a duct is settled on site rather than escalated between contractors.
How does in-house plumbing compare with a subcontracted plumbing package?
Plumbing is routinely awarded to the lowest bidder and inspected least, on the assumption that pipe is pipe. The consequences are consistent and they arrive late. Here is how a subcontracted package compares with running it in-house.
| Typical Subcontracted Approach | IBS Integrated Approach | |
|---|---|---|
| When lines are tested | Tested after the floor and ceiling are closed, if at all, so a leak means breaking finished work to find it | Every supply and drainage line hydrotested before flooring and ceiling close |
| Drainage gradient | Laid to whatever fall the ceiling void allows, which works in an empty building and fails in an occupied one | Set against Indian Plumbing Code gradients at drawing stage and verified before lines are covered |
| Wet-area waterproofing | Left to the civil contractor, applied without a ponding test, and inspected by nobody | Applied and ponding-tested by the same team before tiling, and held before the finish goes on |
| Fixture position versus drainage | Layout frozen by the interior designer, then the plumber discovers the drainage cannot serve it | Fall of the waste line and position of the fixture decided together in one scope |
| Access for future maintenance | Valves and rodding points placed wherever installation was easiest, then sealed behind a finish | Isolation valves and access points positioned so a future blockage can be cleared without opening a ceiling |
| STP and ETP discharge compliance | Treated as a separate vendor's problem, disconnected from the building's drainage design | Integrated with the drainage design and worked to CPCB and State Pollution Control Board consent conditions |

See education projectsCommercials
How is a plumbing package scoped and priced?
Plumbing is quoted against a fixture schedule, the available drainage fall, and any treatment obligation. IBS does not publish per-point or per-square-foot rates, because the same fixture count can carry very different work depending on how far the drainage has to run and how much fall is available to run it in.
What a quotation covers3 clauses
What a plumbing quotation covers
A site survey including drainage invert levels and available fall, water quality assessment where treatment is in scope, supply, drainage and vent design to Indian Plumbing Code gradients, coordination with the interior and other services, first and second fix installation, waterproofing and ponding tests, hydrotesting of every line before closure, commissioning, and the handover documentation file.
What moves the number
Fixture count and its distribution, the drainage route and how much fall is available, whether existing risers and stacks are retained or replaced, incoming water quality where treatment is required, whether STP or ETP works are in scope, and whether the work runs alongside an occupied floor.
What sits outside the scope
Municipal connection charges and statutory approval fees, supply of kitchen equipment itself, and any works to the municipal main or the landlord's base-build risers, which remain with the authority or the building owner.
| Discipline | Term |
|---|---|
| Plumbing installation workmanship | typically twelve months from handover |
| Waterproofing | typically twelve months from handover, subject to the wet area remaining unaltered |
| Sanitaryware and fittings | manufacturer warranty passed through on the specified brand |
| Pumps and treatment equipment | manufacturer warranty passed through on supplied equipment |
| Stage | Terms |
|---|---|
| Advance against Purchase Order | Mobilises procurement of pipe, fittings, and sanitaryware against the approved specification. |
| On completion of first fix and hydrotesting | Payable when concealed pipework is installed, gradients verified, and every line hydrotested, before flooring and ceiling close. |
| On completion of second fix | Payable when sanitaryware, fittings, and equipment connections are installed and ready for commissioning. |
| On commissioning and handover | Released on system flushing, commissioning, and submission of test certificates and as-built drawings. |
No charge, no obligation
Request a Site Survey Site survey
A site survey including drainage invert levels and available fall is carried out before quotation on any project using existing drainage. Assumed fall is the most common source of variation on a plumbing package, because a drainage route that looks straightforward in plan frequently has less available fall than the layout requires, and that is discovered on site rather than on a drawing.
Share the fixture schedule, the drainage arrangement, and whether the space is occupied, and IBS will respond with a scoped plumbing proposal.
Questions
Everything procurement heads, project managers, and admin teams ask before commissioning
These are the questions project managers, facility heads, and procurement teams most often raise when scoping a plumbing package.
Cost & Billing
What is the most common source of cost variation?
Assumed drainage fall. A route that looks straightforward in plan frequently has less available fall than the layout requires, and if that is discovered on site the options are a pumped solution, a raised floor, or a relocated fixture, all of which are more expensive than knowing before quotation. IBS surveys invert levels and available fall before quoting on existing drainage.
Warranty & Service
Are access points for future maintenance planned or improvised?
Planned. Isolation valves and rodding points are positioned so a future blockage can be cleared without opening a finished ceiling. Placing them wherever installation was easiest and then sealing them behind a finish is common, and it converts a routine maintenance visit into a repair job.
How does plumbing coordinate with the other services in the ceiling void?
Drainage is routed first. It has the least flexibility of the four services, because it depends on gradient while cable trays, ducts, and sprinkler lines have more freedom. Coordinating them in the order of their constraint at drawing stage is what avoids the clash being resolved on site by compromising the fall.
Scope & Handover
What documentation is provided at handover?
Hydrotest results recorded per line, ponding test records for wet areas, commissioning records, and as-built drawings showing final routes, gradients, valve positions, and access points. As-built routes recorded accurately are what make the first maintenance visit straightforward rather than exploratory.
Technical
Why does hydrotesting before flooring closure matter so much?
Because it decides what a leak costs. A line tested before the screed goes down and the ceiling closes can be repaired at the joint. The same leak found after handover means breaking the finished floor, and usually repairing the ceiling of the floor below as well. IBS hydrotests every supply and drainage line before closure rather than sampling them afterwards.
What actually causes a washroom that never drains properly?
Almost always gradient. A drainage line laid to whatever fall the ceiling void allowed rather than to Indian Plumbing Code gradients will move water adequately in an empty building and fail once the building is occupied and the flow is real. It is a design and verification failure, not a fixture problem, which is why replacing the fixture never fixes it.
Can IBS take plumbing works without the rest of the fit-out?
Yes. Plumbing can be engaged as a standalone package where a civil contractor or fit-out vendor is already appointed, in the same way IBS takes MEP-only packages. The design, testing, and documentation method is identical whether it runs standalone or inside a full turnkey fit-out.
Who handles the waterproofing, the civil contractor or the plumber?
On an IBS package, the same team that installs the plumbing applies and ponding-tests the wet-area waterproofing. Splitting it is how waterproofing ends up applied without a ponding test and inspected by nobody. Retrofitting it means removing every finish above it, so it is tested and held before tiling starts.
What codes does IBS design to?
The Indian Plumbing Code governs pipe sizing, gradient, and sanitation for supply, drainage, and venting. NBC 2016 Part 8 applies to building services, alongside the fire strategy where plumbing crosses compartmentation. STP and ETP works are executed to CPCB and State Pollution Control Board discharge parameters and consent conditions.
Does IBS handle STP and ETP works?
Yes, integrated with the building's drainage design rather than treated as a separate vendor's scope. Discharge parameters are worked to the applicable CPCB and State Pollution Control Board consent conditions, and treated water reuse for flushing and landscape is provided for where the design allows it.
How is water treatment sized?
Against measured incoming water quality and actual occupancy, not against a standard package. Incoming water hardness varies substantially between locations, and a softener sized against an assumed figure will either be inadequate or will cost more than it needed to. Where treatment is in scope, water analysis forms part of the survey.
Does IBS quote plumbing per point or per square foot?
No. The same fixture count can carry very different work depending on how far the drainage has to run and how much fall is available to run it in. A washroom close to an existing stack and one at the far end of a floor plate are not comparable packages. Quotations are issued against a fixture schedule and a survey of the actual drainage arrangement.
Which sanitaryware and pipe brands does IBS specify?
Brands are agreed at Good For Construction stage against the client's specification and budget, confirmed at order, and substitution requires written approval. IBS does not carry a single fixed sanitaryware brand across every project, because specification on washrooms is usually driven by the client's own standards or by the interior designer.
Can IBS work on an occupied floor?
Yes. Work on live floors is sequenced around occupancy, with water shutdowns planned and agreed in advance and scheduled outside working hours where the client requires it. Washroom cores are typically taken out in phases so the floor retains facilities throughout.
How is kitchen and F&B drainage different from ordinary sanitary drainage?
It carries grease and solids that sanitary drainage is not designed for. Grease traps and interceptors are sized and positioned to the kitchen's output with access for servicing, floor gullies are set for a floor that gets hosed rather than mopped, and equipment connections are coordinated with the kitchen equipment vendor's layout rather than assumed.
Does IBS deliver plumbing works outside Mumbai?
Yes. IBS delivers pan-India, with project teams mobilised from Mumbai. On multi-site programmes the value of central coordination is that the specification and the testing regime are identical at every site rather than reinterpreted by a different local contractor in each city.
