ASTM C1227-20

Standard Specification for Precast Concrete Septic Tanks

ABSTRACT
This specification covers monolithicor sectional precast concrete septic tanks. The following materials shall be used for manufacturing concrete septic tank: cement, aggregates, water, admixtures, steel reinforcement, concrete mixtures, forms, concrete placement, fibers, and sealants. The precast concrete sections shall be cured. Structural design of the septic tanks shall be by calculation or by performance. Concrete strength, reinforcing steel placement, and openings shall also be considered in the design. The physical design requirements include: capacity, shape, compartments, influent and effluent pipes, baffles and outlet devices, and openings in top slab. The following tests shall also be done: proof testing, leakage testing, vacuum testing, and water-pressure testing.
SCOPE
1.1 This specification covers design requirements, manufacturing practices, and performance requirements for monolithic or sectional precast concrete septic tanks.  
1.2 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.  
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
