Irrigation Scheme Tanzania: Commission Approval, Water Permit, EIA and Land

An irrigation scheme in Tanzania is a regulated work, not a private farm improvement. A company that diverts a river, sinks boreholes or lays canals to water a commercial farm meets four separate authorities. Each one issues its own document, and the National Irrigation Commission will not sanction construction until the other three are in hand.

This guide is for investors and farm companies planning a commercial scheme. It sets out the law, the order of approvals, the scheme size bands, the fee lines in Zatra's government fee register and the Zanzibar position. A worked example prices a 600-hectare scheme in shillings.

What the law says

The governing statute is the National Irrigation Act, 2013 (Act No. 5 of 2013). It was published in Act Supplement No. 11 of 31 December 2013. Some summaries call it Act No. 4 of 2013. The printed Act says No. 5.

The Act creates the National Irrigation Commission (Tume ya Taifa ya Umwagiliaji) in section 3. The Commission is an independent government department under the ministry responsible for irrigation. Section 5 gives it coordination, promotional and regulatory functions, including approval of irrigation works.

The core rules for an investor sit in a few sections:

• Section 19 allows registered companies, firms and individual farmers to undertake irrigation works.
• Section 20(1) bars construction until the Commission approves the scheme and it has been subjected to an environmental impact assessment.
• Section 20(3) lists what the application carries, including a water use permit and, for private applicants, a title deed.
• Section 20(5) has the Director General issue an irrigation certificate for each approved work.
• Section 26 sorts schemes into small, medium and large scale, approved or registered at Commission, regional and district level as the regulations provide.
• Section 27 lists the categories of irrigator, companies among them, and the conditions for recognition.
• Section 39 lets the Minister, with the Minister for Finance, prescribe irrigation service fees by order in the Gazette.
• Section 52 sets up the Irrigation Development Fund.

The detail sits in the National Irrigation Regulations, 2015, GN No. 402 of 2015, published on 11 September 2015. The Commission posts its copy on its regulations page.

The Act was amended in early 2025. Daily News reported on 31 January 2025 that Parliament passed a miscellaneous amendments bill giving irrigators' organisations corporate status. The same report cites the Act as Cap. 435. TanzLII holds a consolidation dated 14 March 2025. Confirm the chapter number against the Revised Edition before you cite it in a filing.

Who should read this

• Foreign and local companies planning an irrigated estate for rice, sugarcane, horticulture, avocado or seed.
• Processors building a nucleus farm with outgrowers on a shared canal.
• Lenders and development finance institutions that need proof the scheme is lawful before they disburse.
• Buyers of an existing farm who must check that its irrigation works were approved.
• Farmer groups that want to form an irrigators' organisation and contract with an investor.

A smallholder watering a garden by bucket is outside this guide. The Act bites when works are built and water is taken for commercial irrigation.

Which approvals does an irrigation scheme need?

Four instruments carry most of the weight. The order matters, because each later step asks for the earlier document.

Two more registrations follow the operation, not the works. NEMC charges an annual compliance fee on irrigated cultivation. A packhouse, mill or other processing step needs its own business licence and sector permit. Farming itself sits outside the Business Licensing Act (register NEW-08-16).

How does the National Irrigation Commission register a scheme?

The Act treats a private estate as a scheme like any other. The company applies to construct works, gets a permit, builds to standard and is then recognised as an irrigator within an approved scheme.

The steps under GN 402 of 2015 run as follows:

1. Apply on Form NIA.16 for a construction permit for irrigation works (regulation 29(1)). File it through the Regional Irrigation Engineer (regulation 29(4)).
2. Attach the section 20(3) documents: design report, drawings, bill of quantities, water use permit, title deed and a detailed feasibility study. Add the EIA certificate and pay the non-refundable application fee.
3. The Commission forms an expert team of at least three within sixty days to assess the file (regulation 30).
4. If approved, the Commission issues a permit on Form NIA.17 (regulation 30(3)). A refusal is notified within fourteen days, and the applicant may appeal to the Minister within fourteen days.
5. Build to the approved design. The Commission issues a Certificate of Quality once construction standards are met (regulation 38).
6. Apply on Form NIA.14 for recognition as an irrigator. The Commission issues a Certificate of Recognition on Form NIA.15 (regulation 25). Regulation 24(2) requires a water use permit for irrigation.

The Act sorts schemes by command area in section 2. Section 26 says each band is approved or registered at Commission, regional or district level as the regulations provide.

The 2015 regulations do not set out which office handles each size band. Ask the Regional Irrigation Engineer where your file is decided before you lodge it.

When is a water use permit required for irrigation?

Almost always. Section 43(1) of the Water Resources Management Act, 2009, now Cap. 331, requires any person who diverts, dams, stores, abstracts or uses surface or ground water to apply for a permit. The domestic use exemption in section 11 does not cover commercial irrigation.

The permit comes from the Basin Water Board for the catchment where the water is taken (sections 22 and 53). Section 70 lets the Board set a duration that reflects the purpose and the investment to be recovered. Boreholes also need a groundwater permit under section 55. Our water use permit guide sets out the basin offices and the application file.

Applications now run online. The Ministry of Water and the e-Government Authority built the Water User Information Management System for all nine Basin Water Boards. NatuReS reported on 9 August 2022 that the system was declared ready for use after training that July.

Fees follow the Water Resources Management (Fees Setting) Regulations, 2019, GN 825 of 2019. Each Board sets a unit price by a revenue-requirement formula, flat below a threshold and volumetric above it (register F0522). There is no single national tariff, so the Board assesses the charge. The regulations require a flow meter at each abstraction point before a new permit is issued.

Late payment draws 5% of the outstanding bill for each month of delay (register F0523). Using water beyond the permitted volume or purpose is an offence under section 44 of the 2009 Act.

Which EIA category applies to an irrigation project?

The size of the command area decides. The Environmental Management (Environmental Impact Assessment and Audit) (Amendment) Regulations, 2018, GN No. 474, published on 31 August 2018, list irrigation and drainage in the First Schedule:

• Type A, mandatory full study: irrigation or drainage with a command area of 500 hectares or more. Large-scale cultivation of 100 hectares or more is also Type A, so most commercial estates fall here whatever the irrigation area.
• Type B1, screening decides: irrigation of 200 to 500 hectares.
• Type B2, project brief only: irrigation below 200 hectares, examined and certified without full screening.

Any scheme that moves people needs a resettlement plan attached. NEMC reviews the study, and the certificate is issued by the Minister responsible for environment. Our post on when an EIA is required walks through screening, scoping and review.

NEMC fees come from the Environmental Management (Fees and Charges) Regulations, GN 387 of 2021. The application fee is TZS 50,000 and a scoping report TZS 150,000 (register F0495). Review of a Type A study is banded by project cost (register F0499). After certification, NEMC charges an annual fee on irrigated cultivation (register F0509).

How does a foreign investor hold land for an irrigation scheme?

Through a derivative right or a granted right of occupancy for an approved investment. Foreigners do not own land in Tanzania, and they cannot take village land directly (register F0472). Most large farm blocks sit on village land, so the land must first be transferred to general land. TISEZA then grants a derivative right to the investor.

The irrigation application asks for a title deed. A company with an offer letter or a village minute alone is not ready to file with the Commission. Our guide to agricultural land for investors covers the transfer route, compensation and timing.

The land costs that recur on an irrigated farm are set by regulation:

• Land rent for commercial farms outside urban boundaries is TZS 1,000 per acre a year (register F0456).
• Premium on grant is 0.25% of land value (register F0459).
• Registration of the certificate of title is 50% of one year's rent (register F0462).
• TISEZA charges 10% of the Ministry of Lands processing charge to register a derivative right (register F0473).

Rent is owed whether or not the land is irrigated. Interest runs at 0.5% a month once rent is six months overdue (register F0457).

What is an irrigators' organisation and does an investor need one?

An irrigators' organisation is a group of farmers registered to run and maintain shared irrigation works. Regulation 3(2) of GN 402 of 2015 needs ten or more persons irrigating in one area. The application on Form NIA.1 carries the constitution, committee details, the minutes adopting the constitution and a local government recommendation (regulation 7).

The Commission decides within fourteen days and issues a certificate on Form NIA.4 (regulation 10). A refused applicant may appeal to the Minister within twenty-one days (regulation 12). The management committee has five to nine members, at least one third of them women (regulation 16(3)).

Under section 29(2) of the Act, farmers with land inside a scheme must join once the organisation is registered. The 2025 amendment reported by Daily News lets these organisations contract, own property and borrow.

A company that farms its own block does not need to form one. It matters where an estate shares a canal with smallholders or runs outgrowers. The organisation then becomes the investor's counterparty for water scheduling, canal maintenance and fee collection. Pair it with a registered supply agreement; our contract farming guide explains which regulator registers that contract.

What government fees does an irrigation scheme pay?

Zatra's government fee register holds no line for the Commission's own charges. The Second Schedule to GN 402 of 2015 prescribes the registration and application fees. Irrigation service fees are set by ministerial order under section 39. The Commission posted a notice on irrigation service fee contributions on 25 September 2025. Those amounts are assessed by the Commission, and this guide does not print them.

Government charges are paid to the authority against its control number. The amount on the control number governs on the day of payment. They are separate from any professional fee.

Worked example: a 600-hectare scheme in the Rufiji Basin

Example: a Tanzanian company, majority foreign-owned, plans 600 hectares of irrigated rice and horticulture. It will pump from a river in the Rufiji Basin. The project cost is TZS 12 billion. It wants TISEZA incentives.

The classification follows from the numbers. At 600 hectares the scheme is medium scale under section 2. It is Type A for EIA because irrigation exceeds 500 hectares. In acres the farm is about 1,483 (600 multiplied by 2.471).

Four lines are left out of that total because the authority assesses them. They are the Basin Board's water fee, the Commission's permit fee, the TISEZA charge on the derivative right and the irrigation service fee. NEMC's annual fee also starts once the project runs. The 600-hectare farm sits above the top acreage band of F0509, so ask NEMC how it applies the per-acre rate.

The land value of TZS 900 million is an assumption for the arithmetic. The Chief Valuer's approved figure sets the real premium. TISEZA's minimum capital for a foreign-owned project is TZS 1,500,000,000 (register TZ-02), so this project clears that line.

Timing matters more than the fee total. Under GN 402 the Commission has sixty days to field its expert team. A Type A study, with its baseline seasons and public consultation, usually takes longer than every other step. Start the EIA and the water application together once land is secured.

How does Zanzibar handle irrigation schemes?

Separately. The National Irrigation Act and the Commission serve Mainland Tanzania. In Zanzibar, irrigation falls under the Ministry of Agriculture, Irrigation, Natural Resources and Livestock.

The Ministry's 2025/26 budget speech, presented to the House of Representatives in May 2025, names an Irrigation Department (Idara ya Umwagiliaji Maji). It reports 2,300 hectares with irrigation infrastructure. It also plans a review of the 2002 Irrigation Master Plan. We found no Zanzibar irrigation statute equivalent to the 2013 Act.

For environment, the ZIPA EIA service page says ZEMA issues the certificate. A registered expert prepares the report, ZEMA reviews it and visits the site, and the certificate is valid for five years. ZEMA assesses its own fees. Our post on Mainland and Zanzibar land rights covers the land side.

What happens if a scheme is built without approval?

Building first and applying later is a criminal risk. Section 20(1) bars construction before approval and an EIA. Section 22(2) bars construction without the Commission's sanction.

Section 61 sets the general penalty. For an individual it is a fine of not less than TZS 1,000,000, one to three years in prison, or both. For a body corporate the fine runs from TZS 10,000,000 to TZS 50,000,000. Sections 37, 44, 45 and 47 add offences for unlawful irrigation methods, unlawful water distribution and unplanned canal crossings.

Water and environment laws run in parallel. Abstraction beyond the permit is an offence under section 44 of the Water Resources Management Act. Non-payment of a water bill can draw a fine of TZS 300,000 to TZS 1,000,000 (register F0523). An unapproved project also loses lender support, because few banks fund works without the permits on file.

A notice, a stop order or a prosecution should go straight to an advocate.

What to do now

1. Fix the land first. Confirm the parcel is general land or start the transfer from village land. Obtain the derivative right through TISEZA.
2. Size the scheme. Measure the command area in hectares. That sets the Commission band and the EIA type.
3. Open the water file. Apply to the Basin Water Board through the online system. Budget for the flow meter.
4. Register the EIA project. Appoint a NEMC-registered expert. Submit the scoping report and run baseline studies early.
5. Commission the design. Prepare the design report, drawings, bill of quantities and feasibility study that section 20(3) requires.
6. File Form NIA.16. Lodge it through the Regional Irrigation Engineer with the EIA certificate, water permit and title deed.
7. Build and certify. Construct to the approved design and obtain the Certificate of Quality.
8. Get recognised. Apply on Form NIA.14 for recognition as an irrigator. Register any shared-canal irrigators' organisation.
9. Diarise the annual charges. NEMC fee on 1 July, land rent, water bills and irrigation service fees.

How Zatra helps

Zatra maps the approvals for your site, assembles the land, water, EIA and Commission files, and tracks each authority's clock. Our sector permits service handles the Commission and Basin Board filings. The TISEZA registration service covers incentives and investor land. For the wider entry plan, see our guide to starting an agriculture business as a foreign investor and the EIA compliance page.

Government fees are paid to each authority at the official rate against its control number. They are separate from Zatra's professional fee and are never marked up. Zatra prepares and files; Zatra does not decide or guarantee any authority's outcome. Land conveyancing, disputes, stop orders, prosecutions and legal opinions go to an advocate. To start, contact Zatra with your district, water source and planned hectares.
