Tanzania is increasingly looking beyond its borders for the capital, technology and expertise needed to address growing water challenges, as climate change, population growth and urbanisation put additional pressure on the country's water resources.
The strategy has placed water diplomacy at the centre of efforts to mobilise investment for major infrastructure projects, with Water Minister Jumaa Aweso using international forums to present Tanzania's priorities and seek partnerships.
Mr Aweso represented Tanzania at the Fourth International Conference on Water for Sustainable Development in Dushanbe, Tajikistan, where governments, international organisations, financial institutions and development partners discussed ways of strengthening global water security.
The minister used the platform to highlight Tanzania's progress while calling for greater international participation in the country's water projects.
But beyond diplomatic engagements, the bigger question for Tanzanians is whether such partnerships can translate into reliable water supplies, better sanitation and stronger protection against the effects of climate change.
Tanzania has made progress in expanding access to water, but considerable work remains.
The government says implementation is continuing in 1,575 villages out of 12,333 villages nationwide, indicating that thousands of communities still require improved or expanded services.
The investment requirement is also broader than simply laying water pipes. The country needs financing for dams, treatment plants, distribution networks, wastewater systems, storage facilities and modern technologies. It also needs stronger technical capacity to manage water resources sustainably.
For citizens, the implications are immediate. Unreliable water supplies can increase household costs, affect public health, reduce productivity and place a disproportionate burden on women and children who often spend considerable time looking for water.
This makes investment in the sector not only an infrastructure issue but also a social and economic priority.
Tanzania is also seeking to make the water sector more attractive to private investors.
The revised National Water Policy 2025 and Development Vision 2050 provide a framework for expanding private-sector participation in water production, storage, distribution and resource management.
The government has also highlighted improvements in laws, policies and public-private partnership arrangements as part of efforts to create a more predictable environment for investors.
For Tanzania, private capital could help bridge financing gaps, particularly for projects that require large amounts of money and long-term investment.
At the same time, attracting investment should be accompanied by strong regulation and accountability to ensure that projects deliver value to citizens and that the cost of essential water services remains affordable.
Water diplomacy is taking place against the backdrop of increasingly unpredictable weather patterns.
Droughts, floods and changing rainfall patterns are putting pressure on water sources and infrastructure across many parts of the country.
That makes investment in water storage, resilient infrastructure, early-warning systems and efficient water management increasingly important.
International cooperation could provide Tanzania with access to technologies and expertise that would otherwise be expensive or difficult to acquire.
This was among the issues discussed during Mr Aweso's meetings with international leaders, including Tajikistan Deputy Prime Minister Ziyozoda Sulaymon.
The talks explored possible cooperation in water infrastructure, modern technologies and large-scale water storage.
Tajikistan's experience in managing water resources could provide useful lessons for Tanzania, particularly as the country seeks to improve its capacity to store and manage water amid changing climatic conditions.
Mr Aweso also held discussions with United Nations Deputy Secretary-General for Economic and Social Affairs Li Junhua on Tanzania's water priorities.
The discussions included cooperation in implementing water projects and responding to climate-related challenges.
For Tanzania, stronger engagement with multilateral institutions could help unlock technical assistance, concessional financing and investment partnerships.
However, international commitments will need to be translated into bankable projects, transparent financing arrangements and measurable outcomes if they are to make a meaningful difference to citizens.
Among the major initiatives being promoted is the proposed National Water Grid.
The project seeks to connect major water sources with areas experiencing high demand, creating a more integrated system for the distribution and management of water.
Its implementation would require substantial investment in infrastructure, technology and technical expertise, making it one of the country's potentially significant opportunities for domestic and international investors.
The benefits could extend beyond households. A reliable water system is essential for agriculture, manufacturing, tourism, healthcare and urban development.
Industries cannot operate efficiently without dependable water supplies, while rapidly growing cities need infrastructure capable of keeping pace with population growth.
The National Water Grid could therefore become more than a water project. If properly planned and implemented, it could support wider economic development.
The Kidunda Dam project illustrates the scale of investment required.
The project, conceived about five decades ago, is now being implemented using more than TZS 300 billion in domestic funding, with construction reported to be 52.4 percent complete.
The dam is expected to strengthen water supply to Dar es Salaam, Coast Region and surrounding areas.
Its importance is particularly significant given the rapid population growth and expanding economic activity in Dar es Salaam.
For residents, the real test will be whether such investment produces a more reliable water supply and reduces recurring shortages.
Tanzania's decision to use international diplomacy to attract water investment reflects the growing recognition that government resources alone may not be sufficient to finance the sector's ambitious infrastructure requirements.
The approach could open access to capital, technology and expertise while strengthening Tanzania's links with international institutions and investors.
But attracting investment is only the first step.
The government will need to ensure that agreements result in projects that are financially sustainable, transparently implemented and responsive to public needs.
For citizens, the success of water diplomacy will ultimately be measured not by the number of international meetings held, but by whether more households have dependable access to safe water, whether sanitation improves and whether communities become better protected against droughts and floods.
As Tanzania works towards Development Vision 2050, water security will remain closely linked to poverty reduction, public health, food production, industrialisation and environmental protection.
The challenge now is to convert diplomatic engagement into investment and, most importantly, investment into reliable water services that improve the lives of ordinary Tanzanians.
