Current through Register Vol. 50, No. 11, November 20, 2024

Section XIV-1809 - Appendix D-Vacuum Drainage Systems [formerly Appendix K-Vacuum Drainage Systems]

A. System. A vacuum drainage system shall comply with the following.

1. General. Since a vacuum drainage system is considered an alternate designed plumbing system, the requirements of Chapter 12 of this code shall apply and such systems shall be considered on an individual basis.

2. System Design. Vacuum drainage systems shall be designed in accordance with manufacturer's specifications. The system arrangement, including piping, tank assemblies, vacuum pump assembly and other components necessary for proper function of the system shall be in accordance with manufacturer's specifications. In general, vacuum drainage systems may be considered for approval by the state health officer for use on handling island display refrigerator/freezer condensate wastes in grocery stores. Such wastes from display refrigerators/freezers handling meat or dairy products or other products containing fats, grease or oils shall discharge, in an approved manner, through an approved grease trap prior to discharge into the sanitary sewer system. Also, any food items stored below any portion of a vacuum drainage system (for example, in-the-ceiling vacuum waste piping located above food shelves or food preparation areas) shall be protected from potential contamination by adequate shielding to intercept any potential drips (in accord with LAC 51:XXIII.1503.A.6). Vacuum drainage systems for liquid wastes from other types of plumbing fixtures, such as sinks, water closets, etc., are discouraged. A standby emergency generator, permanently wired to automatically operate the vacuum pump motor upon lost of the normal power source, should be installed to ensure continuous operation of a vacuum drainage system.

3. Plans and specifications. Plans and specifications for such systems shall be designed by a Louisiana Registered Professional Engineer registered in either civil or mechanical engineering and submitted to the state health officer for review and approval prior to installation.

B. Fixtures. Gravity type fixtures used in vacuum drainage systems shall comply with Chapter 4 of this code.

C. Drainage Fixture Units. The drainage fixture load of gravity drainage systems which discharge into or receive discharge from vacuum drainage systems shall be based upon values in Chapter 7 of this code.

D. Water Supply Fixture Units. Water supply fixture load shall be based upon values in Table 1805.B of this code. The load requirement of a vacuum type water closet shall be determined per manufacturer's specifications.

E. Traps and Cleanouts. Gravity type fixtures shall be provided with traps and cleanouts in accordance with Chapters 7 and 10 of this code.

F. Materials. Vacuum drainage pipe, fitting and valve materials shall be as specified by the vacuum drainage system manufacturer and as listed in this Part.

G. Tests and Demonstrations. After completion of the entire system installation, the system shall be subjected to a vacuum test of 19 inches of mercury (64 kPa) and shall be operated to function as required by the state health officer and/or the local plumbing official and the manufacturer. Tests shall be witnessed by the state health officer and/or the local plumbing official. The results of such tests shall be submitted to the state health officer and the local plumbing official.

H. Written Instructions. Written instructions for the operations, maintenance, safety and emergency procedures shall be provided to the building owner and shall be available for inspection by the state health officer and the local plumbing official at any time.
