Irrigation Infrastructure Services Under SAC Code 995422
Irrigation infrastructure services cover construction of canals, water pipelines, sewage pipelines and related systems that move water or waste safely. Contractors handle trenching, laying pipes, supports and testing so that the network works smoothly. Under GST, this work is classified under SAC 995422. The SAC code and its GST rate decide how much GST is charged on such projects and how the value is reflected in GST returns for proper compliance.
Irrigation Infrastructure Services GST Rate for SAC Code 995422
Irrigation infrastructure and sewage pipeline construction services are treated as civil engineering or works contract services under GST. In the earlier years, different contract styles and funding patterns for water and sewage projects sometimes resulted in different effective tax outcomes, which made it difficult for contractors and government bodies to maintain a uniform tax position across similar projects.
After the September 2025 rationalisation, construction services for irrigation networks, water pipelines and sewage pipelines falling under SAC 995422 generally come under the 18 percent slab with input tax credit. This standard rate applies to most such projects, unless a specific notification gives a concessional treatment for a particular government or social scheme focused on rural or low income areas.
The table below gives the latest applicable GST rate for SAC code 995422.

When raising invoices for services under SAC 995422, contractors should clearly show the taxable value and 18 percent GST so that eligible recipients can claim input tax credit in line with the law. The same SAC code and rate should also be followed in GSTR 1 for outward supplies and in GSTR 3B when reporting the tax liability on irrigation infrastructure and pipeline construction services.

SAC 995422 also falls within the broader construction services group 9954, which covers construction of buildings, industrial facilities, roads, bridges, dams and other civil engineering works along with site preparation and building completion services. Each six digit SAC in this group helps classify contracts more accurately based on the main type of structure or system being built or maintained.
The list below highlights key six-digit SAC codes under 9954, excluding 995422.
In day to day practice, a contractor should use SAC 995422 when the main purpose of the contract is construction of irrigation channels or water and sewage pipelines. If the project is mainly for roads, buildings or general site development, another SAC within 9954 may be more appropriate. Correct SAC selection and GST rate application helps reduce the risk of disputes and makes the input tax credit trail easier to justify during scrutiny or audits.
Conclusion
Irrigation infrastructure services under SAC 995422 cover construction of canals, water pipelines and sewage pipelines that move water or waste safely and efficiently. These services are now generally taxed at 18 percent with input tax credit after the September 2025 changes. Contractors and project owners should confirm that their contracts are correctly classified under this SAC code , apply the right GST rate on each invoice and follow the same classification in GST returns. For specialised or subsidised schemes, it is sensible to check the latest GST rules and consult a tax professional.
