(Specification)Standard Specification for Corrugated High Density Polyethylene (HDPE) Grease Interceptor Tanks
Standard Specification for Corrugated High Density Polyethylene (HDPE) Grease Interceptor Tanks
SCOPE
1.1 This specification covers material, design, structural performance, and manufacturing practice requirements for monolithic or sectional corrugated polyethylene grease interceptor tanks with volumes equal to or greater than 333 gallons (1,260 liters ).
1.2 The corrugated high density polyethylene (HDPE) grease interceptor tanks are placed between commercial food service (kitchen) drains and sanitary sewer interceptors to minimize the impact of commercial food service effluent containing grease, oils, soap scum and other typical commercial food service wastes on the sanitary sewer system. Typical sources of commercial kitchen effluent are scullery sinks, pot and pan sinks, dishwashers, soup kettles and floor drains where grease containing materials may exist.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This specification covers pipe and fittings for horizontally laid corrugated HDPE grease interceptor tanks as illustrated in Fig. 1.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
