After the subdivision gained preliminary plat approval, the developer found that the public sewer line could not be extended across the road. Following this disclosure, DHHS met with the developer and his engineer in an attempt to continue the plat with on-site sewage disposal. Soil tests and water monitoring subsequently performed on Lot 7C have shown that the lot is unsuitable for development due to poor soils and a high water table. The State ADEC has issued concept approval for a system on this lot; however, we have challenged that approval on technical grounds. In spite of the ADEC approval, this department concludes that the lot is unsuitable for development without pzALic sewer, and we will not sign the final plat. f�bbZ1 Susan Oswalt On -Site Services-.

NOV 419986 RECEIVED s 41) the North on-site new 7 -Eleven Eagle River As I understand it, a condition of approval of our Plat No. S-8471 requires us to assure the Municipality that an acceptable method will be used to handle our on-site sanitary sewer disposal. We have accepted the recommen- dation of DHHS and DOWL Engineers to not use a convent- ional septic tank/drainfield system. Our -plans are to purchase'a Rid Waste System from Alaska "Technological Applications; Inc:; -for installation on site. We under- stand this system will allow us to discharge effluent directly into the high water table in an acceptable manner. Based on our understanding that the Rid Waste System has been approved by ADEC and DHHS and that a municipal direct discharge permit exists for this system, we are planning the installation of the Rid Waste System. We have requested and received a quote from the supplier. A copy of their October 29, 1986 letter is attached for your further information. It is our intention to accept this quote and authorize purchase and installation of the Rid -Waste System to fulfill the requirements of our plat approval. On this basis, we would appreciate your assist- ance in providing DHHS sign off on final Plat No. S-8471 for this property. Thank you.

A Ends Capped Relief Line L.A Distribution Pipe and Relief Trench to be Level Line Relief Line 279 C' box networks (see Figure 7-23). However, .the design makes it more difficult to add trenches to the system and it does not permit the owner to manually rest the upper trenches. The network uses overflow or relief lines between trenches in place of drop boxes. The invert of the overflow section should be located near the top of the porous media to use the maximum capacity of the trench, but it should be lower than the septic tank outlet invert. The invert of the overflow from the first absorption trench should be at least 4 in. lower than the invert of the pretreatment unit outlet. Relief lines may be located anywhere along the length of the trench, but successive trenches should be separated 5 to 10 ft (1.3 to 3.0 m) to prevent short- circuiting. f. Pressure Distribution If uniform distribution of wastewater over the entire infiltrative sur- face is required, pressure distribution networks are suggested. These networks may also be used in systems that are dosed since the mode of the network operation is intermittent. To achieve uniform distribution, the volume of water passing out each hole in the network during a dosing cycle must be nearly equal. To achieve this, the pressure in each segment of pipe must also be nearly equal. This is accomplished by balancing the head losses through proper sizing of the pipe diameter, hole diameter and hole spacing. Thus, approximately 75 to 85% of the total headloss incurred is across the hole in the lateral, while the remaining 15 to 25% is incurred in the network delivering the liquid to each hole. The networks usually con- sist of 1- to 3 -in. (3- to 8 -cm) diameter laferals, connected by a cen- tral or end manifold of larger diameter. The laterals are perforated at their inverts with 1/4 to 1/2 in. (0.6 to 1.3 cm) diameter holes. The spacing between holes is 2 to 10 ft (0.6 to 3.0 m) (see Figures 7-24 to 27). Pumps are used to pressurize the network, although siphons may be used if the dosing chamber is located at a higher elevation than the lateral inverts.. The active dosing volume is about 10 times the total lateral pipe volume. •This ensures more uniform distribution since the laterals, drained after each dose, must fill before the network.can become prop- erly pressurized. (See Section 8.3 for dosing chamber design.) 278 MUNICIPALITY OF ANCHORAGE S 4-7 MEMOPANnum DATE: December 8, 1986 TO: Don Bennett, Planning Supervisor, AWWU Engineering FROM: Susan Oswalt, On -Site Services, DHHS# SUBJECT: S-8471, Walter G. Pipple SID our review of this proposed subdivision occurred this past spring, when Planning sent us the case. Our comments at that time were that we had no objection to subdividing into three lots provided public sewer and water were extended to all lots. Uniortunately, immediately after the short plat was approved by the Platting Officer, we were informed that although public water was available, public sewer extension was an impos- sibility. It was understood by me that the line crossing the road was not large enough to accommodate the planned addition, and there were several other technical difficulties which made extension impractical and not economical. Throughout our continued discussions with DOWL we assumed that sewer could not service these lots. Note that we also assumed that the sewer line in question was across the road, not 1200 feetaway. As discussions progressed, we then asked for soils information and required that the subdivision be reduced to two lots. We have spent the past several months negotiating the way in which a sewer system would have to be installed. Included in this has been meetings with ADEC, and we required ADEC's approval prior to moving forward on the subdivision. At long last, although we still maintain that the land in the proposed subdivision is not well suited to on-site sewer, we have reach agreement with the applicant and his engineers. On December 3, 1986, I signed the Summary of Action in preparation for final plat sign -off. The applicant has met the requirements of this department. Page 2 Bennett It is certainly not clear to me whether information was withheld from us regarding the sewer line; however, it was not until my recent discussion with you that I realized my discussions with the applicant and yours were about two different connection points. There are lessons to be learned here. First, perhaps we need to require all preliminary plats to show the location of the proposed tie-in so that AWWU has a fair chance to review. Secondly, perhaps my department should take a closer look at subdivisions proposing public sewer. And certainly in the future, when a subdivision is approved with public sewer and subsequently (for whatever reason) fails to provide it, this department will take immediate steps to have the approval of the subdivision revoked. In the past I know we have diligently attempted to work together on these type of problems and I trust that cooperation will continue. It is especially important so that customers do not play departments against each another. I trust this will clarify our understanding of what has trans- pired on this subdivision review. Please call me at 264-4718 if you have any other questions. SEO/aen cc: Platting Officer R. W. Robinson
