Water supply pipeline system is a key issue in urban lifeline engineering, and the seismic assessment for the system damage is of significant importance. In this study, method of seismic damage assessment on underground water supply pipeline is introduced. With emphasis on the uncertainties of earthquake level, ground condition, soil-pipe interaction and capacity to resist pipe deformation in longitudinal direction, the check point method is applied to the reliability study of water pipeline, and a case study is presented to show the implementation of the proposed model.

While the water management systems of Minoan Crete are legendary, water management on the Greek mainland in the Mycenaean period also shows a high degree of technological sophistication. Projects considered in this paper include the draining of the Kopais Lake, generally agreed to be one of the greatest engineering achievements of early antiquity; the cistern at Mycenae with its corbelled access tunnel cut deep into the bedrock of the citadel; the twin springs at Tiryns, with their underground passageways approached through the massive ‘cyclopean’ walls; and the North Fountain on the Mycenaean Acropolis of Athens. These Mycenaean systems are compared with the remarkable underground water supply system at Troy uncovered by the recent excavations led by Manfred Korfmann, a structure which may date to the beginning of the 3rd millennium and which appears to be invoked among the deities of Wilusa (Troy) in the early-13th century treaty between Muwattalli II of Hatti and Alaksandu of Wilusa (and which may be a precursor of the famous Persian qanats).

The article presents the results of assessment works on drinking groundwater of alluvial sediments of the river valleys, perspective for water supply of mountainous regional centers of the Chechen Republic (Itum-Kale, Khimoi, Shatoi and Vedeno villages). The problem of providing quality water to more than 65,000 people living in four regions of the Chechen Republic mountainous areas is becoming more and more critical every year. According to the technical (geological) task, water demand for drinking and domestic water supply of the population is 4.0 thousand m3/day. The assessment of groundwater reserves for domestic and drinking purposes directly in the areas of the above-mentioned settlements was not made earlier, except for Itum-Kalinskoye, where in 2012–2013 HIDEK CJSC performed prospecting and assessment of the underground water reserves in the area of the projected riverbed water intake for the needs of the ”All-season ski resort Veduchi”. Based on the results of these works, the Khacharoiakhk field of fresh groundwater was explored in the alluvial deposits of the Khacharoiakhk River valley, which belong to the upper quaternary and modern quaternary system.
