Facts about plastic pipes
Plastic pipe is a tubular section, or hollow cylinder, made of plastic. It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow ? liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.
There are three basic types of plastic pipes:
Solid wall pipe
Extruded pipes consisting of one layer of a homogeneous matrix of thermoplastic material which is ready for use in a pipeline
Structured wall pipe
Structured-wall pipes and fittings are products which have an optimized design with regard to material usage to achieve the physical, mechanical and performance requirements. Structured Wall Pipes are tailor made solutions of piping systems, for a variety of applications and in most cases developed in cooperation with users
Barrier pipe
Pipe incorporating a flexible metallic layer as the middle of three bonded layers. Barrier pipe is used, for example, to provide additional protection for the contents passing through the pipe (particularly drinking water) from aggressive chemicals or other pollution when laid in ground contaminated by previous use.
Most plastic pipe systems are made from thermoplastic materials. The production method involves melting the material, shaping and then cooling. Pipes are normally produced by extrusion.

Plumbing code - Wikipedia:
Plumbing code is a code that provides regulations for the design, installation and inspection of building plumbing and sanitary systems. In the U.S., jurisdictions enact their own codes, some of which are based upon model plumbing codes.1 The most widely adopted plumbing code in the United States is the International Plumbing Code published by the International Code Council (ICC). This code is also used as the basis for the plumbing code of some other countries. Another model plumbing code published in the United States is the Uniform Plumbing Code published by IAPMO.

Creating a network of water and sewage built school
A very important project carried out in built school is equipping it with a functioning network plumbing. Responsibility for the good execution of the plan created previously borne by the administration building, and then selected by the administrative authorities, the director of the school. It should also ensure that the school building was carried out a review of the state of water and sanitation, especially during the holiday season and, if necessary, during the school year. Performance of plumbing repairs in the school can deal with an emergency plumber or hydraulic depending on the type of failure. Therefore, to carry out such repairs may involve the need to close only one of the toilets or the entire school building.
