Facility Piping Systems Handbook, Second Edition
Using a total systems approach, this handbook progresses from fundamentals of system and component operation to a design procedure that allows quick and accurate component and pipe sizing.
TABLE OF CONTENTS Facility Piping Systems Handbook, Second Edition
Chapter 10: SPECIAL WASTE DRAINAGE SYSTEMS
This chapter describes and discusses the collection and criteria necessary for the design of liquid effluent from various special waste drainage systems other than discharge from sanitary and storm water sources. Except for the neutralization of acid effluent, treatment methods are outside the scope of this chapter.
Each waste system discussed has unique properties that must be separately addressed. These systems are generally routed from fixtures and equipment into a local facility waste treatment system, with the treated effluent discharging directly into the public sanitary sewer system. Very often, untreated waste is stored on site and collected by approved waste removal contractors for disposal.
Unless specifically noted otherwise, all of the waste streams will be assumed to have the approximate flow characteristics of water. Pipe sizing criteria is based on this assumption.
CODES AND STANDARDS
There are two general jurisdictional bodies that regulate different aspects of special waste systems.
The first is the local and regional authorities that create and enforce plumbing and health codes. Included are the local authorities charged with review and approval of plumbing systems design. They are concerned primarily with regulating sizing and design of the piping systems within buildings. Their regulations generally mention special system piping material, treatment and system configuration. They do not mandate specific use of double-wall piping or leak detection. These requirements are mandated by federal, local and state agencies. Recommendations for piping material usually require that any pipe material be approved by the local authority and be capable of resisting degradation...
