JUNEAU May 14, 1976 Mr. Doug Dickinson 2607 Arctic Blvd Anchorage, AK 99503 R & M NO. 654114 RE: Storage for Sanitary Wastes Warehouse Project Gentlemen: We have reviewed the sanitary waste aspects of your proposed warehouse project, and would make the following comments. The basic warehouse space is 40,000 sq. ft. for this occupancy we would assume a maxiumum of 1 warehouseman per 5,000 sq. ft., for a total of 8 persons. The largest contribution to the expected flows would be generated by the office space. Using the maximum space proposed for offices (9,000 sq. ft.) and a maximum occupancy of 150 sq. ft. per person, office per- sonnel could total up to 60 people. Total maximum occupancy,- as developed here is then 68 persons. AS a matter of interest, Pepsi Cola is in the process of constructing a new warehouse. The total footage in this building is in excess of 30,000 sq. ft. Total personnel at this building, including office staff and warehousemen, is about 12 people. This of course does not include drivers, who are out of the building most of the time, but even including these, the equivalent total occupancy is probably less than 20 people. Using a quantity of 15 gallons per day per person, the following estimated 3 days storage requirements can be developed. 1) Minimum Occupancy (30) 30 x 15 gpcd x 3 = 1350; say 1,500 Gal. 2) Expected Probable Occupancy (45) 45 x 15 gpcd x 3 = 2025; say 2,500 Gal. 3) Maximum Probable Occupancy (68) 68 x 15 gpcd x 3 = 3060; say 3,250 Gal. Based on the preceding, we would recommend the installation of a minimum size holding tank of 3,000 gallons. This should be sufficient for a 3 day storage capacity, even under the more extreme conditions. If the Mr. Doug Dickinson May 14, 1976 Page 2 tank is oversized based on final occupancy, less pumping will be required. Conversely, if the occupancy is higher than anticipated, it might be possible that the tank would have to be pumped a little more frequently. Since pumping costs could be significant, you may also want to consider installing fixtures which require less water for Operation. The additional costs for these units may be justified by potential savings in pumping costs, and become even more economical if there is any possibility that sewers may not be installed in the area'in the near future.
