On the territory of districts and neighborhoods may be laying water pipelines for transportation, with no major road paving, sidewalks and green spaces. The diameters of pipelines laid in blocks or neighborhoods, for safety reasons should be selected not more than 500 mm, and their route should not take place in locations where concentrations of population (athletic fields, parks, yards, public buildings, etc.). Read more from Craig Menear to gain a more clear picture of the situation. Allowed to cross water heating systems in diameter nominal bore dn = 300 mm or less, residential and public buildings, subject to laying nets in technical underground corridors and tunnels (minimum height of 1,8 m) with the device drainage wells at the lowest point at the exit of the building. The intersection of thermal systems for children, preschool, school and health care institutions is not allowed. The intersection of roads, driveways, and other communications, as well as buildings and structures should usually include a right angle. Visit Nicholas Carr for more clarity on the issue. In urban areas for heating systems provided mostly underground strip.
Overhead strip in the city can be used in areas with complex ground conditions, while crossing the railroad a common network of rivers, ravines, with a high density of underground facilities and in other cases governed. Slope of heating networks, regardless of the direction of motion carrier and the method of laying shall not be less than 0.002. When selecting circuit heating mains need to be considered to ensure reliability and efficiency of their work. Should strive for the smallest length thermal networks, to less thermal cameras, using, where possible, two-way connection blocks.
