Water Pipeline

Water pipeline construction is an important component of underground pipeline utility construction. There are three main types of water pipeline systems typically installed in any new public or private construction project: domestic, fire and reclaimed water pipeline. As we all know, water is a precious resource that serves many functions and must meet stringent installation guidelines, and comply with other health and safety code regulations.

Domestic water pipeline is used inside your home, office or institution and is intended for consumption and contact with the body. This water has gone through a series of tests to ensure that it is safe for human consumption. It is also used for dishwashing, clothes washing and toilets on a regular basis. Construction pipeline companies carefully install these domestic water pipeline systems using several testing procedures; i.e. they test for leaks by conducting a pressure test and test for the absence of e-coli and other bacteria. Domestic water is brought from wells and reservoirs through water pipelines to the water agencies and then pumped to your community through local water pipeline mains. Water agencies continually test their water for purification.

Fire water pipeline, or fireline, is used for fighting fires. A fire water pipeline system typically starts at the detector check backflow device, which is also the divider of domestic water and fire water pipelines. The backflow device prevents the fireline from contaminating an Agency's domestic water main supply. It also protects the domestic water system from being pressurized when the fire department pumps up the fireline. From the backflow device, the fire water pipeline continues underground to service the fire hydrants, and into the building to service the private fire sprinkler systems. Fire water pipelines are not intended for drinking. You will notice most private fire water pipeline designated by the color red. Most private fire hydrants, appurtenances, and signs will be painted red.

Reclaimed water pipeline is generated from home and office drains that include shower and sink water, washing machine water, dishwasher water, and toilet water. All of these types of water are called gray water. This gray water travels through pipes to a facility where the gray water is processed through several stages, removing solids and debris, breaking down organic material with microorganisms, filtering the water, and finally, disinfecting the water. The gray water has now been reclaimed, or recycled, and is pumped through reclaimed water pipelines to the end user.

Reclaimed water is most commonly used for irrigation, but it is also used for certain industrial uses, certain fire water, and some toilet water. Reclaimed water is not intended for drinking. Reclaimed water pipeline is designated by the color purple. Anything that holds reclaimed water and is above ground should be painted purple, and all signs should have a purple color too. This is a common requirement.

Water pipeline in general is typically designed by civil engineers to fulfill the needs of the community depending on the type and nature of business. Water pipelines are built to code depending on which city and/or governing agency will be responsible for maintenance of the water pipeline infrastructure. Unlike most sewer and drainage storm systems (because some sewer and drainage is pressurized as they have to pump it up hill and then can use gravity to flow downstream), water pipelines run on a pressurized system, and do not solely use gravity to direct flow.

Land developers, water agencies, engineers and contractors must keep up with demand for new and better pipeline systems not only to ensure public safety, but also to recycle and reuse this multi-faceted resource to the maximum benefit. As a result, public works projects continue to dominate the need for installation and continued maintenance of water pipeline.
