Quick4 Equalizer 36 Chamber System Sizing in New York
Table 1 provides chamber adsorption system sizing guidance based on the NYSDOH Interoffice Memorandum,Onsite Wastewater Treatment Systems;Specific
Waiver Criteria-Gravelless Systems and Secondary Treatment Units(STUs),dated November 24,2004. This NYSDOH memorandum provides trench length data
based on a 25%length reduction and design flow reduction from 130 to 110 gpd/bedroom. Table 2 provides similar chamber sizing guidance to Table 1 with
respect to the length reduction,but assumes a design flow of 130 gpd/bedroom.

FULL AND REDUCED LENGTH ABSORPTION AREA AND VOLUME COMPARISON
Equalizer 24 chamber sized @ 1:1 with a 2-ft-wide gravel trench and 130 GPD/bedroom
-Design criteria:current Appendix 75-A trench length sizing ► Open bottom absorption area=0.98 sf/If x 217 If=212.7 sf
-Percolation rate:8-10 minutes per inch ► Storage volume=4.5 gal/If x 217 If=976.5 gal
-Home size:3 bedrooms
-Required system length:217 If of trench(per Appendix 75-A Table 4A)
-Equalizer 24 chamber open bottom area:0.98 sf/If
-Chamber storage capacity:4.5 gal/If
Quick4 Equalizer 36 chamber sized @ 25%length reduction and 110 GPD/bedroom
-Design criteria:trench length sizing per November 24,2004 ► Open bottom absorption area=1.61 sf/If x 138 If=222.2 sf(4%greater than
NYSDOH memorandum Equalizer 24)
-Percolation rate:8-10 minutes per inch ► Storage volume=8.0 gal/If x 138 If=1,104 gal(13%greater than Equalizer 24)
-Home size:3 bedrooms ► Trench length difference=217 ft-138 ft=79 ft(36%less than Equalizer 24)
-Required system length:138 If Conclusion:Although the absorption system is"reduced"in length compared to the
(per November 24,2004 NYSDOH interoffice memo) length of the Equalizer 24,more absorption area and storage volume are provided using
-Quick4 Equalizer 36 chamber open bottom area: 1.61 sf/If the Quick4 Equalizer 36 chamber.
-Quick4 Equalizer 36 chamber storage capacity:8.0 gal/If

Table 1 and 2 Notes:
1.Sizing chart based on NYSDOH Interoffice Memorandum,Onsite Wastewater Treatment Systems;Specific Waiver Criteria-Gravelless Systems and Secondary
Treatment and Secondary Treatment Units(STUs),dated November 24,2004. Until changes to Appendix 75-A are promulgated,a specific waiver must be obtained for
reduced length systems,as described in the memo.
2.Apart from the sizing shown above,all Appendix 75-A design requirements for absorption trench systems are applicable.
3.Trench length data shown above does not include the length of the MultiPort End Caps.The laying lengths of the inlet and outlet end caps are 14.5 and
11.5 inches,respectively.
