Alaska Water & Wastewater Services 8471 Brookridge Drive Anchorage, Alaska 99504 Subject: Lot 4A Block 2 Cromwell Heights Subdivision PID #015-332-27, Permit #SW920090 As-built Drawing Dear Mr. Garness: On February 13, 1994, you provided (by FAX) information relative to the proximity of the absorption field to a slope on the subject lot of approximately 35%. In view of the five feet or more of fill added after the absorption field was installed, coupled with the very permeable accepting soil strata, there is a minimal chance of the effluent daylighting from the face of the slope. In our further review of the as-built drawing dated July 15, 1992, additional information has surfaced which requires further investigation of this wastewater disposal system. Permit #SW920090 was designed and approved for a conventional wastewater disposal system sized to handle the wastewater generated for a four bedroom single family residence. Your as-built drawing shows that the system was installed in accordance with the design attendant to the permit. Information recently received by this office brought the following matters to our attention. The septic tank and leachfield are being utilized as a "grey water" system. The residence is served by holding type toilets. The waste solids generated by the subject residence are being disposed of by composting and possible incineration. Jeffrey Garness, P.E. February 23, 1994 Page Two In the issuance of the on-site wastewater disposal system permit, none of the above items were mentioned nor were they included in your as-built drawing. If any of the above items do exist, you must provide full details accordingly including but not limited to manufacturer's specifications, installation details and drawings, operating details, "black water" disposal process, and the method of disposal of the "composted" material. The subject as-built drawing will not be approved by this office until the above requested information is progided. If you have further questions, please call ou~ office at 343-4744.

The blackwater from the toilets and the garbage disposal are separated from the graywater from the sinks, Showers, tubs and dishwasher. 'lhe blackwater runs into an AlasCan Composting tank. Thc graywater runs into a separate AlasCan waStewater tank. 'lhe outflow of the wastewater 'tank runs into a 1,250 gallon conventional septic tank and drain field, designed and approved for the more normal combined black and graywater disposal. The composting tank is an active system consisting of a large heavily insulated, aerobic digestion tank with two thner-controlled agitators. three ratchet driven augers, an automatic sump pump and an exhaust fan vented through the roof by a dedicated 3' ABS pipe., The wastewater treatment system ls another large Insulated tank separated into three stages of extended aeration using the suspended growth process of cleansing. Water flows through the system by the · power of rising air supplied by a small compressor, The, first stage is a surge chamber to handle the heavy surges of normal water use. ~a .me~.an/L~othet solids colkct on the l bottom of,/~ach ~be~~~ ·.~' :' and are' Pumped. into the' :~6~poSting tank for fttrt~he~r SENT BY:,,~C0 .~.SK,~.

A bottle of the Nepond lasts approximately one month per toilet, The continuous foaming action provides for another 'odor barrier should the venting system fail or become blocked (heavy 'snowfall over the roof vent. for example). The ¢ompostlng toilet is started with a few hundred pounds of sawdust/wood chips and, abcn~t 50 pounds of fishy peat potting soil. At intervals of approximately one year about 10 gallons of compost are removed. Under normal operation there is no discharge from the composting tank. Excess moisture is evaporated out of the composting tank. by diverting the state air exhaust of the Vent Air Air-to-Air heat exchanger that continuously exhausts 120 cfm of air. The outflow of the wastewater system will be monitored for an in'itial period of one year after initial occupancy. Analysis will be made on the compost upon removal. The res'ults will be submitted to the MOA is an att'erupt to receive approval fOr additional wastewater system installations. ..
