THE SIGNAL IN ONE SENTENCE
Uganda has a serious reason to want computing infrastructure of its own. Synectics Technologies plans a large AI and data-centre campus near the Karuma Hydroelectric Power Station, powered by electricity from the Victoria Nile. The company says new graphics processors will use direct-to-chip cooling and that water loss will be minimal. Nature Africa reported on September 14 that researchers still cannot test that promise because the public record lacks a specific water-usage figure, a complete cooling design, planned withdrawal volumes, discharge details, and an environmental and social impact assessment. This is not proof that the project will drain or pollute the Nile. It is proof that low-carbon electricity and low water use are different claims. A cooling plate can recirculate fluid in a neat little loop while the building around it still uses river water, cooling towers, treatment systems, or other equipment. Before Karuma calls the system green, the project needs to publish both ledgers: the river and hydropower account that supplies the electricity, and the facility account that records every litre taken, consumed, treated, and returned.
01
WHAT ACTUALLY CHANGED
Nature Africa published a September 14 examination of the planned Karuma facility and the water information that remains unavailable. The report identifies Synectics Technologies as the developer and says the company plans a high-performance computing centre, several AI factories, and a regional training academy. These are planned components. Nature Africa does not report that the computing campus is operating.
Synectics chief executive Oladele Oyekunle told Nature Africa that the project will use direct-to-chip cooling for its graphics processors and that water loss will be minimal. In this design, coolant passes through small channels in a plate attached to the chip, absorbs heat, moves through a heat exchanger, and circulates again. When the heat exchanger releases heat through dry coolers, direct water consumption can be much lower than in an evaporative cooling tower.
The company has also described natural river water cooling from the Victoria Nile, which it says is roughly half a kilometre from the project site. That phrase leaves several designs possible. River water might exchange heat with a sealed internal loop and return to the river, supplement another cooling system, or support wider building cooling. Each arrangement has a different withdrawal, treatment, temperature, and ecological profile. Synectics has not published enough engineering detail to tell readers which complete system is planned.
Oyekunle said the facility's water usage effectiveness would be close to zero, but Nature Africa reports that he supplied neither a specific number nor supporting documentation. The company has not posted an environmental and social impact assessment or an expected water-use document on its website. Without the numerator, boundary, operating load, season, and cooling configuration, close to zero is a direction of travel, not a measurable result.
The schedule also remains a projection. Oyekunle told Nature Africa that the computing portion is expected to begin operating in the second quarter of 2027 and that the full development may take three years. The company website still displayed an earlier second-quarter 2025 start. That mismatch matters because construction status, design maturity, permitting, and equipment choices determine how much confidence anyone should place in environmental performance claims.
02
WHY THIS MATTERS
Hydropower can lower operational carbon emissions compared with a fossil-heavy electricity supply, but it is already part of a river system. The power station changes how water moves through infrastructure, while the data centre may create its own intake and return flow. Those are related accounts, not one account. Calling the electricity renewable does not calculate the facility's direct consumption or the river conditions under which it can operate safely.
Withdrawal and consumption are easy to blur. A facility can withdraw a large volume, use it to carry heat, and return most of it. The consumptive share is what evaporates, becomes part of another product, or otherwise leaves the local water system. Returned water still matters because temperature, treatment chemicals, timing, and discharge location can affect aquatic life even when the volume looks nearly unchanged.
Direct-to-chip cooling answers one engineering question well: how to remove dense heat from processors. It does not automatically answer how the coolant itself is cooled, how server rooms and electrical equipment are conditioned, how humid weather changes performance, what happens during maintenance, or whether backup systems use evaporation. A complete diagram needs to start at the intake and end at the final discharge or loss.
Local disclosure is an economic issue as much as an environmental one. Uganda could gain computing capacity, skilled work, research infrastructure, and a local place to train and run models. Nearby communities carry the immediate consequences of noise, construction, land use, electricity allocation, and water decisions. Publishing the design lets residents, universities, regulators, and investors distinguish a valuable infrastructure project from an attractive rendering and a pile of adjectives.
The wider lesson travels beyond Uganda. United Nations University warns that AI infrastructure has carbon, water, and land footprints that do not move together. Low-carbon power can still have substantial water or land effects, while a low-water cooling system can draw electricity from a carbon-intensive grid. Environmental claims should identify the boundary being measured instead of letting one good metric impersonate the whole footprint.

WHERE IT COULD HELP
- Publish a facility-wide water balance showing the source, hourly and annual withdrawals, consumptive use, recirculation rate, treatment, blowdown, final discharge, and expected performance in wet and dry seasons
- Report water usage effectiveness at design load and partial load, define exactly which water sources and systems are included, and publish both the estimate and measured values after commissioning
- Separate the closed chip-cooling loop from building cooling, river-side heat exchange, humidification, cleaning, sanitation, construction, and emergency systems in one plain-language diagram
- Set intake, return-temperature, water-quality, and drought operating limits with named monitors, public results, independent review, and a clear process for slowing or stopping the facility when limits are crossed
- Pair environmental disclosure with local-benefit evidence such as construction status, jobs by skill level, training completion, research access, electricity contracts, community consultation, and procurement from Ugandan suppliers
KEEP A HAND ON THE WHEEL
Nature Africa's September 14 article is reporting and analysis, not an environmental assessment or proof of damage. Synectics says direct-to-chip cooling will keep water loss minimal and that its water usage effectiveness will be close to zero. Those remain company claims without a published figure or supporting design document. Direct-to-chip systems can use a sealed coolant loop, but the final method for rejecting heat from that loop determines much of the water demand. Natural river water cooling is not a complete engineering specification. The public record reviewed here does not establish the intake location, maximum withdrawal, consumptive use, recirculation rate, cooling-tower role, treatment chemistry, blowdown, discharge location, return temperature, drought limit, monitoring plan, water permit, environmental and social impact assessment, construction progress, or measured lifecycle emissions. The computing start in the second quarter of 2027 and three-year campus timeline are developer expectations, not completed milestones. Watch for a filed assessment, regulator decisions, detailed mechanical plans, community consultation records, construction evidence, independently reviewed water calculations, and measured performance after commissioning.

TERMS WORTH KEEPING
OPEN GLOSSARY CARD
Water usage effectiveness
A data-centre metric that divides water consumed by the energy used by computing equipment over the same period and within a stated boundary.
OPEN GLOSSARY CARD
Water withdrawal
Water removed from a river, reservoir, aquifer, or utility supply for use by a facility, whether or not most of it is later returned.
OPEN GLOSSARY CARD
Consumptive water use
The part of withdrawn water that does not return promptly to the same local water system because it evaporates, is incorporated elsewhere, or is otherwise lost.
