Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses pipes, valves, plumbing fixtures, tanks, and other apparatuses to convey fluids.[1] Heating and cooling (HVAC), waste removal, and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications.[2] The word derives from the Latin for lead, plumbum, as the first effective pipes used in the Roman era were lead pipes.[3] In the developed world, plumbing infrastructure is critical to public health and sanitation.[4][5]

Omisej Engineers are skilled in making this happen and creating the network needed to handle any and all quantities of fluids with scale, reliability and performance in mind.

The major categories of plumbing systems or subsystems are:[19]

• potable cold and hot tap water supply
• plumbing drainage venting
• sewage systems and septic systems with or without hot water heat recycling and graywater recovery and treatment systems
• Rainwater, surface, and subsurface water drainage
• fuel gas piping
• hydronics , i.e. heating and cooling systems using water to transport thermal energy, as in district heating systems, like for example the New York City steam system .

Omisej as a whole is more geared towards Industrial plumbing; designing and implementing systems to meet the needs of Industries and related manufacturers.
