Compressed Air Systems

This chapter discusses compressed air for industrial laboratory and commercial applications. Compressed air is a major source of power possessing many advantages: It is safe, economical, easily transmitted, and adaptable. It is used to produce linear motion, and it also is employed to actuate linear movement through a piston and cylinder or a diaphragm. Atomizing, spraying, and moving hard-to-pump fluids are other applications. Compressed air can be bubbled up to measure fluid levels, agitate liquids, and inhibit ice formation in bodies of water. Another use of compressed air is for instrumentation. Air circuits solve the most complex problems in auto­matic control. Some applications would be almost impossible with any power medium other than compressed air.

Fire Protection Systems

The two main purposes for fire protection systems within built environments are life safety and property protection. Equal measure must be implemented to attempt to contain a fire while protecting a build­ing’s occupants during their evacuation. Absolute safety from fire is not attainable, but means must be provided to minimize the potential for fire and the damage done by fire. The systems and methods used today are constantly changing and improving to meet the requirements of project variations and challenges. This chapter provides the reader a basic outline for establishing the needed criteria to establish fire safety, via fire suppression, within a building environment.

Drainage Systems

The design of the domestic sanitary-drainage and vent systems are standard plumbing systems, with effluent discharging directly into the public sanitary sewer. All plumbing fixtures and equipment and all sanitary-drainage piping shall be designed and installed in strict conformance with the applicable plumbing code for the project location. In terms of the design of these systems, there is nothing unique to pharmaceutical facilities; however, this chapter explains some unique types of waste, including laboratory waste, acid waste, radioactive waste, infectious waste, and chemical waste.

Valves

It probably would be impossible to find an industry anywhere in the world in which valves do not perform an important and vital function. Today’s valves are basically the same types that were available 10 en or more years ago. However, some valves are rapidly replacing others in popularity. Two of the most commonly specified valves (gate and globe) are being hard pressed by ball and butterfly valves. This chapter discusses the different types of valves, their components, and how to choose the correct valve for each application.

Fuel Gas Piping Systems

This chapter describes fuel gas systems on consumer sites from the property line to the final connection with the most remote gas appliance or piece of equipment. The system is intended to provide sufficient pressure and volume for all uses. Since natural gas (NG) is a nonrenewable energy resource, the engineer should design for its efficient use. The direct utilization of NG is preferable to the use of electrical energy when electricity is obtained from the combustion of gas or oil. However, in many areas, the gas supplier and/or governmental agencies may impose regulations that restrict the use of natural gas.

Sanitary Drainage System

The purpose of the sanitary drainage system is to remove effluent discharged from plumbing fixtures and other equipment to an approved point of disposal. A sanitary drainage system generally consists of horizontal branches, vertical stacks, a building drain inside the building, and a building sewer from the building wall to the point of disposal. The discussion in this chapter centers only on the design of
drain and waste systems.

Private Sewage Disposal Systems

The May/June 2007 continuing education article is "Private Sewage Disposal Systems," Chapter 21 of Engineered Plumbing Design II by A. Cal Laws, PE, CPD.

With the ever-increasing cost of land located in proximity to urban centers, more and more construction is being implemented in outlying areas. Sanitary sewers are not usually available in these remote locations and it becomes necessary for the plumbing engineer to design private sewage systems to handle the wastes from buildings. Where the concentration of population is not sufficient to economically justify the installation of public sewer systems, installation of a septic tank in conjunction with a subsurface soil absorption field has proven to be an exceptionally satisfactory method of sewage disposal. This chapter explains the different types of private sewage disposal systems for residential and commercial applications as well as criteria for their design and construction.

This chapter describes water-based emergency drench equipment and systems commonly used as a first-aid measure to mitigate the effects of such an accident. Also described are the breathing-air systems that supply air to personnel for escape and protection when they are exposed to either a toxic environment resulting from an accident or normal working conditions that make breathing the ambient air hazardous.

May/June 2006

Reflecting Pools and Fountains

Plumbing engineers, architects, and landscape architects all are involved in the creation of display fountains and reflecting pools. The architects are concerned with the overall aesthetics, whereas the engineers must be familiar with the available fountain equipment and the technical details of each component if they are to design systems that will achieve the desired display effects. The plumbing engineer should work closely with the architect and the landscape architect to achieve the desired display. In addition, the systems should be designed with provisions for cleaning, water treatment, and maintenance.

Custom fountains providing small or large water displays with almost any desired decorative effects are discussed in this chapter. Also included are the technical details of pool design, mechanical equipment, including spray systems, and operation and maintenance. The engineer must also be aware that the fountain is usually represented on a set of architectural drawings as an undefined space or a rendering. It is also usually the last item to be coordinated. What this means is that the engineer usually designs the fountain in its entirety, including the water effect and its influence on the surrounding area. Then, he needs to quickly (and accurately) select the nozzles, determine flow rates, select the equipment, try to get space for the equipment, and coordinate with the other disciplines involved, then coach contractors, who look upon a fountain as a glorified swimming pool.

Plumbing Design for Health-Care Facilities

Health care facilities, nursing homes, medical schools, and medical laboratories require plumbing systems that are more complex than those for most other building types. The plumbing designer should work closely with the architect and facility staff and be involved in meetings and discussions in order to fully understand the plumbing requirements for any new or special medical equipment. The plumb­ing design must be coordinated with the civil, architectural, structural, mechanical, and electrical designs to ensure that adequate provisions have been made for utility capacities, for the necessary clearances and space requirements of the piping systems and related plumbing equipment, and for compliance with applicable codes. Health care facilities may have different requirements or be exempt from some codes and standards, such as water and energy conservation codes and regulations regarding the physically challenged. The plumbing engineer should consult with the administrative authority in order to ensure conformance with local ordinances.

This chapter discusses the provisions that may be encoun­tered by the plumbing professional in the design of a health care facility, including the following: plumbing fixtures and related equipment, sanitary drainage system, water supply system, laboratory waste and vent systems, pure water systems, and medical gas systems.

January/February 2006

Medical Gas and Vacuum Systems

Health care is in a constant state of change, which forces the plumbing engineer to keep up with new technology to provide innovative approaches to the design of medical gas systems. In designing medical gas and vacuum systems, the goal is to provide a safe and sufficient flow at required pressures to the medical gas outlet or inlet terminals served. System design and layout should allow convenient access by the medical staff to outlet/inlet termi­nals, valves, and equipment during patient care or emergencies.

This section focuses on design parameters and current stan­dards required for the design of nonflammable medical gas and vacuum systems used in therapeutic and anesthetic care. The plumbing engineer must determine the needs of the health care staff by determining answers to the following fundamental design questions at the start of a proj­ect:

1. How many outlet/inlets are requested by staff?
2. How many outlet/inlets are required?
3. Based on current conditions, how often is the outlet/inlet used?
4. Based on current conditions, what is the average duration of use for each outlet/inlet?
5. What is the proper usage (diversity) factor to be used?

Valves

Valves serve the purpose of controlling the fluids in building ser­vice piping. They come in many shapes, sizes, design types, and materials to accommodate different fluids, piping, pressure ranges, and types of service. Proper selection is important to ensure the most efficient, cost-effective, and long-lasting systems. No single valve is best for all services. This chapter is limited to manually operated valves that start, stop, and regulate flow and prevent its reversal.

Jail and Prison Housing Units

The criteria used to design hot water systems for jail housing units differ from those used for prison housing units. This difference is due to the fact that the facilities are used for different purposes. Jails are used primarily to house people awaiting trial or serving short sentences. Prisons are used to house convicted criminals serving long prison terms. This difference affects the prisoners’ daily routines, which, in turn, determine when the facilities’ peak hot water demands occur.

The objective of this chapter is to help the designer under­stand and deal with the problems of designing water heating systems for jail and pris

on housing units. It is important that the designer recognize that each building is unique and work closely with the owner, architect, and government authorities to determine how a building will operate. A building’s opera­tion will affect when and for how long the peak hot water demand will occur.
The first part of this chapter discusses generally some of the design criteria and areas of special concern involved in designing jail and prison housing units. The second part gives two practical examples of sizing methodology, one for jails and one for prisons.
