Water Supply Pipeline

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.

The Relationship

The article is devoted to the practical implementation of the results of the analysis of the relationship between the system of technical regulation in construction and the regulatory regulation of relations for the provision of public services. Changes in the current normative documentation in the sphere of water supply of apartment buildings are considered. It is shown that it is necessary to improve the methodological basis for designing inhouse systems of cold and hot water supply in an apartment building and to create a legitimate methodological tool. Recommendations for improving the regulations 30.13330.2016, «internal water pipeline and sewerage of buildings. Actualized edition of construction standards and regulations 2.04.01-85» are proposed. Changes in the Construction Regulations 30.13330.2016 and the results of their expertise are given.

Ad Libitum Feeding

The first purpose of this experiment was to investigate the effect of ad libitum feeding of peat as a supplement to piglets from the age of five days up 23 days of age on their growth performance and health status. The second purpose was to assess the risk of the occurrence of conditionally pathogenic mycobacteria (CPM) in peat treated with ionizing radiation (Group PI) or per acetic acid (Group PP) and fed as a supplement to piglets. In respective experimental periods (at the age of 4, 23, 41 and 67 days), no significant differences in the average body weight between control group (C) and experimental Groups PI and PP were detected. Levels of selected biochemical (total protein, albumin, glucose, cholesterol, Ca, P, Fe and I) and haematological (erythrocytes, leukocytes and immunoglobulin – Ig) parameters of the health status of the piglets from all three Groups C, PI and PP were comparable at the age of 41 and 67 days. Mycobacteria were detected by culture in one diet sample (Mycobacterium intracellulare), in all 10 peat samples (7 M. a. hominissuis isolates, 2 M. intracellulare isolates and 1 M. xenopi isolate) and in 4 samples of biofilm from the drinking water pipeline system in the stables (M. xenopi, M. a. hominissuis, M. gordonae and Mycobacterium sp., one isolate in each). In 15 slaughtered pigs (at 67 days of age), no gross lesions that would give evidence of tuberculosis were found either in lymph nodes or parenchymatous organs. In Group C, mycobacteria were detected in tissues from two piglets (Mycobacterium sp. and M. a. hominissuis), Group PI in four piglets (M. a. hominissuis) and in Group PP in all five piglets (Mycobacterium sp., M. a. hominissuis, M. terrae and M. intracellulare). High positivity for CPM in both types of treated peat caused disseminated infection of the digestive tract of piglets from Groups PI and PP. Based on these results, feeding peat treated with ionisation or per acetic acid may be viewed as risky.

Water Pipeline

This paper presents a case study of BP’s Mardi Gras Gulf of Mexico deep water pipeline transportation system. The Mardi Gras Transportation System (MGTS), operated by BP Pipelines, N.A. has set the standard for large diameter, deepwater pipeline design, construction and maintenance. The pipelines range in size from NPS 16 to NPS 30 in water depths up to 7,300 ft. The paper showcases the ArcGIS and PODS relational database management tools and the process of how we implemented programs to track underwater facility features and their displacements caused by the 2005 hurricane season. We will describe the challenges, solutions and new technology used to monitor and maintain the integrity of this pipeline system, even when covered by 5000 feet or more of water. Submarine (ROV) inspection technology, digital video and GPS are the order of the day. We shall demonstrate how GIS can assist in managing and reporting the results of the inspections and setup a database for long term managment of the pipeline system.
