APPENDIX C CALCULATIONS
Holding Tank Capacity Sample Calculations:
Sample Calculation: Households served per holding tank
TLVC = (DSF)(PSF)+(DSF)(3 days) Where: TLVC = total liquid volume capacityDSF = daily sewage flow
for PSF = 7 days PSF = pumping service frequencyand TLVC = 6,000 gallons:
6,000 gal = (DSF)(10 days)
DSF = 600 gal/day
DSF = (H)(SF) Where: H = number of households
600 gal/day = (H)(120 gal/day)
H = 5
Sample Calculation: Households served per service period
H = (LVCT)/(SF*PSF) Where:
for LVCT = 3,000 galSF = 120 gal/dayPSF = 3.5 days
H = 7.14
SF = sewage flow per household per day = 120 gal/day
LVCT = Liquid Volume Capacity of the tanker

List of Approved On-site Sewage Tanks
Washington State Department of Health Page 7 List of Approved On-site Sewage Tanks January 16, 2008
SECTION 1 – Introduction and Overview
Chapter 246-272A WAC takes full effect on July 1, 2007 (WAC 246-272 ceases to exist). Chapter 246-272A WAC allows only sewage tanks that have been reviewed and approved by the Department to be used. Sewage tank is defined as a prefabricated or cast-in-place septic tank, pump tank/dosing chamber, holding tank, grease interceptor, recirculating filter tank or any other tanks as they relate to on-site sewage systems including tanks for use with proprietary products. The approved sewage tanks are currently listed in the “List of Approved Systems and Products”.
On March 15, 2007 the current “List of Approved Systems and Products” will cease to exist. This document “List of Approved On-Site Sewage Tanks” will replace the list of approved wastewater tanks on the “List of Approved Systems and Products”. All the sewage tanks listed on the “List of Approved Systems and Products” will transfer over to the “List of Approved On-Site Sewage Tanks”.
The following sections present manufacturer and product information for various sewage tanks. This information is presented in the following lists:
�� Concrete Tanks Approved by Local Health Jurisdictions (statewide, by county) These tanks, approved by local health departments / districts, are acceptable to Department of Health and may be used in that local health department/district.
Please note that some local health jurisdictions do not have a formal process for evaluating wastewater tanks. Designers are advised to check with the local health jurisdiction to confirm which tanks are permitted.
This list is frequently updated, yet may not contain all tanks in current use in a given county. Local health jurisdictions may add or make corrections to this list by contacting the department.
�� Concrete Tanks Approved by the Washington State Department of Health This list reflects information about sewage tank reviews and approvals by the department since January 1, 1995. These tanks may be used statewide.
�� Non-Concrete Tanks Approved by the Washington State Department of HealthThis list contains tanks constructed with fiberglass or polyethylene. This list reflects information about sewage tank reviews and approvals by the department since January 1, 1995. These tanks may be used statewide.
Answers to questions regarding sewage tank standards or information about application for product review and approval may be obtained from Mamdouh El-Aarag, P.E. at (509) 456-2754 or [email protected].

GEWater & Process TechnologiesZENON Membrane Solutions
How Membranes WorkMembranes are based on filtration methods found throughout nature. ZeeWeed membranes are hollow polymer fibers with billions of microscopic pores on the surface. The pores are much smaller in size than common contaminants, bacteria and viruses. This physical barrier only allows clean water to pass through while rejecting impurities—guaranteeing an exceptional water quality and clarity on a continuous basis. A slight vacuum is all that is required to draw water into the membrane fiber and filter out impurities.

ZeeWeed packaged plants provide large-scale performance in a compact pre-assembled system
Incorporating a simple and expandable building-block design, ZENON packaged plants can be quickly set up in virtually any location and feature scalable treatment capacity that can be increased as demand grows. These highly automated, plug-and-play UF systems outperform conventional treatment alternatives in all categories, offering superior treated water quality that meets or exceeds regulatory requirements, reduced operating costs, smaller plant footprints, and highly reliable performance—at a price that is comparable to conventional systems.
