Better water management can increase demand for pumps that move water reliably and use energy efficiently—but replacing a pump does not, by itself, save water. In Thailand, agriculture and water-supply infrastructure are important demand contexts; the market’s growth figures are commercial estimates, not official national statistics.
Why water management can drive pump demand
Water management involves matching water supply, storage, delivery and use to demand. Pumps are part of that system: they can lift or distribute water for irrigation, utilities and other applications. Investment in water infrastructure or more controlled delivery may therefore create demand for pumps, replacement parts, installation and maintenance.
That connection is not the same as proof that pump upgrades reduce water consumption. A more efficient pump may use less electricity to move a given amount of water, but whether a farm, utility or industrial user takes less water depends on how the whole system is designed and operated. For example, the amount pumped, timing, leakage, irrigation method and end-user practices all matter. The available evidence does not establish a nationwide water-saving figure from pump replacement.

The same provider estimates agriculture at 37.6% of application share in 2026 and centrifugal pumps at 47.1% of type share that year. These are forecast segment shares from the commercial report, not independently verified national data. They indicate the report’s view of where demand may sit; they do not show that one pump type is right for every farm or water system.

Where efficiency improvements may matter
Irrigation-pump design and operation
A 2023 study by W. Sanghirun and W. Asvapoositkul examines surface-water irrigation pumps used by smallholder farmers in South and Southeast Asia, including Thai pumps. In the designs analyzed, more than 63% of total entropy generation was attributed to turbulent distribution. This is a modeled result for the study’s analyzed designs, not a field measurement of all Thai irrigation pumps or a national estimate of wasted energy.

The study’s authors note that many surface-water irrigation pumps in Thailand are made by local companies for domestic use, without restrictions on hydraulic design. That observation points to a potential role for better design and appropriate operating conditions, but the pump still has to be selected for its actual job. The paper’s introduction also reports that earlier design work at 1,500 rpm found efficiency ranging from 40.2% to 54.2%; that range belongs to the earlier work cited there, not a field test in the 2023 study. Read the 2023 pump-loss study.
Monitoring utility pump energy
The OECD’s 2022 report on managing and financing water for growth in Thailand describes analyzing real-time or daily pump performance and wattage, comparing units, and simulating pump operation as ways to examine energy used in water transport. Such monitoring can help operators identify where energy use differs across equipment or operating conditions. It is a management approach, not a quantified estimate of market growth or water savings. Read the OECD report.

Solar pumping is an option, not a universal answer
A 2025 engineering article discusses photovoltaic water pumping for Thai agriculture and compares pump types and AC/DC configurations. In the direct-coupled photovoltaic setup described, an AC pump requires an inverter; the article describes DC pumps as more efficient and versatile in that context. Those characteristics do not establish a universal preference: system performance depends on the pump, power electronics, operating conditions and application. Read the photovoltaic pumping article.
When assessing a solar system, consider the available solar resource and whether the design needs an inverter, controls or energy storage. A design should also account for when water is needed: a system that pumps when sunlight is available may require storage of water or electricity, depending on its configuration and operating schedule.

How to compare pumps for a real water system
Start with the work the pump must do, then compare options against that duty. A market-share estimate or a general claim about efficiency cannot replace system sizing.
- Application and source: Identify whether the pump serves irrigation, building supply or another use, and whether water comes from surface water, a well, a tank or a network.
- Flow and head: Specify the required flow rate and total head, including the lift and resistance in the pipework. Compare hydraulic performance at the actual operating point, not just a headline rating.
- Water quality: Check for sediment, debris or other solids and confirm the pump is suited to those conditions.
- Power and controls: Assess the availability and reliability of grid electricity, fuel or photovoltaic power, along with any inverter, controls or storage required.
- Lifecycle practicality: Compare initial and operating costs, maintenance needs, local service access and parts availability.
- Applicable requirements: Verify the safety and efficiency rules that apply to the specific pump and use.
Check standards and water-measurement rules by scope
Requirements are not interchangeable across pump categories or water users. The TISI record for TIS 60335 Part 2(41)-2567 reports an effective date of 21 June 2025 and covers household and similar electric pumps, while excluding certain pumps for industrial use. Confirm the original standard and the pump’s classification before relying on it for a compliance decision. See the TISI record.

A separate 2024 water-use measurement notice has a defined scope for certain public-water users; the cited index says it excludes water from irrigation canals and groundwater. The Department of Science Service index also lists a separate centrifugal-pump energy-efficiency notice. The index entries alone do not establish which rule applies to a particular installation or its full requirements, so consult the original applicable notice.
