APPENDIX N Smoke Testing Study* *The following is a summary of the Smoke Testing Study. A complete copy of the findings and results are on file at the City. ---PAGE BREAK--- ---PAGE BREAK--- 1 of 9 Smoke Test Report and Summary Puyallup, WA Background Hydromax USA’s Sanitary Sewer Assessment project for The City of Puyallup was completed during the months of August and September of 2015. Smoke testing identifies defects that allow extraneous flow into the collection system. Smoke testing is performed during dry weather periods so that soil moisture does not prevent the smoke from permeating through the soil. This approach helps to maximize the number of defects that can be identified. This report includes the following items: • Smoke Test Field Procedures • Summary of Findings • Sewer Lines With Defects Identified • Severe Defects • Defective Pipe Segment Summaries • Pipe Segment Detail Sheets Smoke Test Field Procedures Prior to conducting smoke testing field work, notification was provided to the public located in the study area. The notices were distributed via door hangers. The public notices provided information about the purpose of smoke testing the sewers, the schedule, and what to do if smoke entered the house. The local fire and police departments were also notified of the smoke testing effort and schedule. The door hangers were distributed to residents in the study area at least two to three days prior to the start of the smoke testing effort. Each morning during the smoke testing, the police and fire departments were notified of exact areas where smoke testing would be conducted that day. Smoke was blown into the areas sanitary sewer system at the manholes using a high-volume, gasoline-fueled smoke blower. Non-hazardous smoke was produced by introducing petroleum hydrocarbon smoke fluid on the hot manifold of the blower. This permitted the continuous supply of smoke during the test, providing enough time for defects to be found and identified. Each smoke test setup was conducted over a maximum of 1,000 ft of sanitary sewer pipeline. Complete overlap of smoked pipe segments occurred for all segments when possible. Photos were captured of each defect that was observed. The locations where smoke was observed were recorded with handheld, sub-meter accuracy GPS data collectors. Information regarding the characteristics of the defect and its surrounding area was also recorded. GPS coordinates ---PAGE BREAK--- 2 of 9 were collected for each of the manholes in the study area to document smoke coverage and provide precise measurements of the footage tested in this study. The location of each defect is presented with dimensions referenced to the nearest upstream manhole and pipe segment in the Detailed Findings section of the report. Summary of Findings Smoke testing was conducted from 8/24/2015 to 9/2/2015 on 96,575 linear feet of mainline gravity sewers. 213 defects were identified and documented during the smoke testing effort. Shapefiles have been provided with the electronic copy of the reporting. These shapefiles document the pipe segments smoke tested and the location of defects. They show the pipe segments that were successfully smoke tested and the locations of defects that were identified. Table 1 presents a summary of the smoke test results, including line segment count, total linear feet of sewer line smoke tested, and the number of defects identified. Table 1: Smoke Test Results Summary Smoke Test Results Summary Total Number of Pipe Segments 413 Total Linear Ft of Sewer Line Smoke Tested 96,575 Total Number of Defects Identified 188 Sewer Lines with Defects Identified Table 2 presents a list of pipe segments which were found to have defects. It displays the number of defects observed per pipe segment. Table 2 is sorted by “Number of Defects” to present the pipe segments with the most defects observed first. Table 2: Sewer Lines with Defects Identified ---PAGE BREAK--- 3 of 9 ---PAGE BREAK--- 4 of 9 ---PAGE BREAK--- 5 of 9 Severe Defects A severe defect is regularly associate with one of three different types of defects: Catch Basins, Downspouts, and Drainage Ditches. Based on our findings, there are 82 severe defects to report at this time.

Pipe Segment Detail Sheets Detail sheets for each pipe segment are presented to show the location of the pipe segment and any associated defects that were found during the smoke test inspection. The defects are presented with detailed dimensions from the nearest pipe segment and upstream manhole to facilitate easy location in the field. Other details such as defect type, smoke rate, drainage area, elevation, address, comments, and photos are provided. The supplementary volumes of this report contain the pipe segment detail sheets. The detail sheets for the project are grouped by the pipe segments with defects and those without. The purpose of the detail sheets showing no defects is to document the full coverage of the smoke testing and record that no defects were found when appropriate. ---PAGE BREAK--- ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! 15TH ST NW 4TH AV NW TACOMA RD 5TH ST SW 5TH ST NW 62ND ST E 18TH ST SW 19TH ST NW 2ND ST NW 106TH AV E 9TH ST NW 10TH AV NW 4TH ST NW 13TH AV NW W MAIN W MAIN 18TH ST NW 7TH AV NW 4TH AV NE 10TH STPL NW 62ND STCT E 7TH ST SW BRIDGE AV NE 2ND AV NE 6TH ST NW 105TH AVCT E ELM PL 63RD STCT E 2ND ST SE 3RD ST SW 4TH ST SW 2ND ST SW 19TH ST SW 7TH AV NW 6TH ST SW 14TH STPL NW 15TH STPL NW 10TH AVCT NE 7TH ST NW E MAIN 5TH AV NW 20TH STPL SW 8TH AVPL NW 12TH STCT NW 14TH ST SW 13TH STCT NW 9TH ST SW 4TH ST NE 14TH ST NW 12TH AV NW 10TH AV NW 5TH ST SE 4TH AV NW 8TH AVCT NW 13TH ST SW 8TH ST NW 6TH ST NW 13TH PL NW 10TH ST SW 10TH ST NW 8TH ST NW 9TH AV NE 11TH ST NW 9TH ST NW 12TH ST NW 2ND ST NW E MEEKER 3RD ST NW 5TH AV NE 12TH ST SW 2ND AV NW 8TH AV NW 6TH AV NW 19TH STCT NW 11TH ST NW 11TH AV NW 15TH ST NW 13TH ST NW 11TH ST SW 9TH ST NW 20TH ST NW W MAIN 2ND AV NW W MEEKER 61ST ST E 4TH AV SW 7TH AV NW 4TH AV SW 20TH ST NW 3RD AV NW 5TH AV NW 59TH ST E 9TH AV NW 8TH AV NW 8TH ST NW 6TH AV NW 13TH ST NW 12TH AV NW 3RD AV NW 11TH AV NW 16TH ST NW 15TH ST SW 16TH STPL NW 17TH ST NW 9TH AV NW 8TH ST SW 16TH ST SW 17TH ST SW 17TH STPL NW 12TH ST SW 10TH ST SW 4TH AV NE 7TH AV NE 8TH AV NE 19TH ST NW 18TH ST NW 17TH ST NW 3RD ST NE 4TH ST NE 5TH ST NW 4TH ST SE 12TH ST NW PEACH PARK LN 8TH AV NW 9TH AV NE 16TH ST SW 18TH ST SW 8TH AV NW MCELROY PL 17TH ST NW 7TH AV NW SPRING ST 21ST ST NW 12TH AV NW 16TH ST NW 15TH ST NW 5TH ST NE E MAIN MILWAUKEE AV E W STEWART E STEWART 3RD ST SE 3RD ST NE N MERIDIAN E PIONEER W PIONEER S MERIDIAN 2ND ST NE 167 5025 5021 5020 5255 5008 5004 5002 5027 5050 5062 5026 5057 5058 5057 5050 5044 5130 5117 5117 5117 5117 5125 5117 5117 5116 5115 5100 5093 5128 5115 5113 5222 5221 5217 5217 5217 5217 5211 5211 5211 5211 5195 5167 5170 5170 5221 5213 5162 5170 5167 5168 5246 5170 5170 5235 5228 5228 5240 5253 5255 5255 5262 5247 5247 5249 5251 5251 5251 5413 5259 5290 5285 5286 5286 5314 5302 5266 5266 5292 5284 5284 5284 5316 5275 5307 5339 5360 5360 5360 5406 Defect Type !
