Records and sources

Ordered by start date. Long lives and processes may begin before the period you want to study.

1. 6000 BCE–3000 BCE

   Irrigation and early settlement in Mesopotamia

   Canals and flood management supported agriculture in parts of Mesopotamia over millennia. The infrastructure was neither a single invention nor a sufficient cause of cities: it depended on labour, ecology, institutions, and conflicts that varied by basin and period.

2. 312 BCE

   Aqua Appia and Rome’s urban water supply

   The Aqua Appia was Rome’s first aqueduct according to Roman documentary tradition. It increased urban supply capacity, but does not allow an inference of equal water access among residents or replace other systems of wells, fountains, and distribution.

3. 256 BCE

   Dujiangyan irrigation system

   Dujiangyan diverted and distributed Min River water through works without a closing dam. Its long continuity illustrates maintenance, adaptation, and basin administration; it does not mean the system remained socially or environmentally identical for more than two millennia.

4. 900–1400

   Angkor’s hydraulic landscape

   Angkor’s reservoirs, canals, and dikes formed part of a large urban and agricultural landscape. Archaeology shows repairs and changes over time; the infrastructure should therefore be understood as a maintained and vulnerable system, not a stable machine that by itself explains the city’s rise or decline.

5. 1858–1875

   London main drainage and Bazalgette’s sewer network

   After the sanitary and political crisis of 1858, the Metropolitan Board of Works implemented Joseph Bazalgette’s interceptor-sewer system. The network moved wastewater away from central London and its main works were completed in 1875. This entry records a material and institutional response; it does not replace John Snow’s epidemiological investigation or assign every health outcome to one project.

6. 1885–1940

   Punjab canal colonies and the colonial category of “Crown waste land”

   Punjab’s canal colonies were organised on land that British authorities classified as “Crown waste land,” a category that gave the administration control over distribution. The classification and irrigation enabled new agricultural allocations, but they are not a neutral description of prior use and claims. This entry separates the administrative framework from effects that varied across communities, settlers, and canal zones.

7. 1922

   Colorado River Compact

   Representatives of the basin states and the U.S. federal government signed the Colorado River Compact on 24 November 1922. It divided the basin into upper and lower sections, leaving later allocations within each. It is a milestone in interstate allocation and a legal foundation for later works; it is not, by itself, a complete allocation, a guarantee of stable hydrology, or evidence of equal power among all peoples connected to the river.

8. 1931–1936

   Construction of Hoover Dam

   Construction of Hoover Dam began in 1931 and the work was dedicated in 1935; it formed part of the Boulder Canyon Project authorised after the Colorado River Compact. Its purposes included flood control, storage, and power generation. A dam’s technical capacity does not by itself determine who receives water, electricity, or protection from risk: those outcomes also depend on contracts, law, operations, and power relations.

9. 1960–1970

   Aswan High Dam, Nubia, and displacement

   Construction of the Aswan High Dam transformed the upper Nile valley and created a large reservoir affecting Nubia in Egypt and Sudan. UNESCO documents the international campaign launched in 1960 to rescue threatened monuments and also recognises the displacement of Nubian people after villages were flooded. This entry does not fix one resettlement total: estimates depend on sources, time periods, and counting criteria.

10. 1960

    Indus Waters Treaty

    India, Pakistan, and the World Bank signed the Indus Waters Treaty in 1960 after nine years of negotiation. It allocated the western rivers—Indus, Jhelum, and Chenab—primarily to Pakistan, and the eastern rivers—Ravi, Beas, and Sutlej—primarily to India, with permitted uses on the other set and a permanent commission. The signing created rules and channels for information; it did not eliminate the basin’s geographic asymmetries, technical disagreements, or political tensions.

11. 1961–1966

    Akosombo Dam, Lake Volta, and resettlement

    Akosombo Dam, built for the Volta River Project, created a large reservoir and entered service in 1966. World Bank records describe the resettlement of about 80,000 people from hundreds of villages into dozens of new settlements. This entry links hydropower and resettlement without reducing them to one balance sheet: housing, land, services, and later outcomes were uneven and need evaluation community by community.

12. 1977

    UN Water Conference at Mar del Plata

    The 1977 Mar del Plata conference produced an international action plan on water and sanitation. It set priorities and cooperation, but did not itself create funding, infrastructure, or universal access; those outcomes depended on governments, institutions, and communities.

13. 1992

    Dublin Principles for integrated water management

    The 1992 Dublin conference formulated principles that influenced integrated water-resources management, including water’s economic value and women’s role. They are policy principles, not a neutral recipe: application has generated debates about rights, tariffs, participation, and inequality.

14. 2000

    Cochabamba water conflict

    Protests in Cochabamba challenged a water concession, tariff increases, and service rules; the government ultimately rescinded the contract. The case shows that tariffs, infrastructure, debt, and public control can intertwine, but does not make all private or community management experiences equivalent.

15. 2010

    UN recognition of rights to water and sanitation

    In 2010 the UN General Assembly recognised the human right to safe drinking water and sanitation. Recognition offers a normative and accountability framework, but does not automatically distribute networks, finance, or protection from contamination and shutoffs.

16. 2015

    Sustainable Development Goal 6

    The 2030 Agenda included SDG 6 for water and sanitation, with targets on access, quality, efficiency, integrated management, and ecosystems. The targets support comparison of progress, but national averages can conceal inequalities by place, income, gender, migration status, or rurality.

17. 2023

    2023 UN Water Conference

    The 2023 conference gathered voluntary commitments in the Water Action Agenda. It is a space for international coordination, not a binding treaty or a guarantee of implementation: follow-through depends on resources, transparency, and action by public, community, and private actors.
