Mahāsena had built the famous Minneriya tank there, and between the fourth and ninth centuries a number of smaller tanks in the region would have helped sustain a considerable population producing a substantial agricultural surplus. The economic importance of the region was further enhanced by the development of commercial relations with China and South-East Asia, in which the port of Gokonna (modern Trincomalee) would have played a prominent part. Thus the adoption of Polonnaruva as the capital of the Sinhalese kingdom by four kings of the period between the seventh and tenth centuries, and the final abandonment of Anurādhapura in its favour, were determined as much by considerations of economic advantage as by strategic and military factors. §REF§ (De Silva 1981, 31) De Silva, K.M. 1981.

The first joint activity was the purchase of an icebreaker that could secure the passage of different water vessels during winter. These water ships didn't take water only upstream of the Amstel, but also from the river Gein near Abcoude, a distance of 15 km southeast of the city. Because of quality, soon water was taken from the Vecht near Nigtevecht, about 20 km from the city. [...] Barge canals were constructed to connect the city with both rivers. [...] Every morning multiple water vessels departed from the city to the different water inlet sites and returned to the city by night. The brewers sold the water from the water vessels to the inhabitants of Amsterdam and to the sea captains of the port of Amsterdam. In 1695 a new icebreaker was purchased, this time financed by the brewers guild, which included all Amsterdam brewers. [...] The price of water increased to 15 (guilder) cents per bucket, because of the costly operation of the icebreaker. For poor people this price was too high. These people had to melt ice from the canals, which resulted in many sick people. In hard winters it was no longer possible to cover the costs of the operation because of the low sales and the high operation costs. Therefore, the brewers decided to cease water transport during periods requiring the use of the icebreaker. However, the city council signed a municipal order in 1745 and again in 1769 that required the water supply to continue during winter. [...] To break through the deadlock about the use of the icebreaker, the municipality of Amsterdam took over the icebreaker and a number of water vessels in 1786. They formed the Versch-Water Societeit to oversee the water supply from the Vecht. This society granted concessions to water merchants for transportation and trading within the city. The brewers were only allowed to transport water for their own consumption. They had to pay a sum per water vessel to cover the costs of the icebreaker.\"§REF§(Van Dijk, Verberk, and De Moel 2006: 50-52) Seshat URL: https://www.zotero.org/groups/1051264/seshat_databank/collections/7F5SEVNA/items/RKMJB7RS/collection.§REF§ NB Because Amsterdam was the de facto capital of this polity, we are inferring that if it did not feature a structural drinking water supply system, neither did other centres." }, { "id": 277, "polity": { "id": 633, "name": "sl_anuradhapura_1", "long_name": "Anurādhapura I", "start_year": -300, "end_year": 70 }, "year_from": null, "year_to": null, "tag": "TRS", "is_disputed": false, "is_uncertain": false, "name": "Drinking_water_supply_system", "drinking_water_supply_system": "present", "comment": null, "description": " “The outer reaches of the city are defined by the presence of three artificial lakes, the Basawak Kulam, the Tessa Wewa and the Nuwara Wewa covering areas of 91, 160 and 1288ha respectively.

Mahāsena is credited with the construction of sixteen tanks and canals, four of which are in the Anurādhapura area, and one in the Puttalam district. Three notable trends in the development of irrigation facilities during his reign were: a resolute endeavour to harness the waters of the Mahaväli and the Ambangaṅga, the most important project being the massive Minneriya tank; the improvement of facilities for water conservation in the north-western part of the island; and the attempt to develop the south-western part of the dry zone on the periphery of the wet zone. Together they accelerated agricultural development in the vicinity of Anurādhapura, and opened up new areas for cultivation in the east and southwest. All the major irrigation projects initiated by him were achieved by a prodigious investment of labour resources on an unprecedented scale, and they reflect, too, a notable advance in irrigation technology in the island.” §REF§ (De Silva, 1981, 29).
