TranscriptionSegment 87: Sewage Air Date: October 5, 2004 Tease @ 20:53 "We're here in beautiful Emerald Bay. What does this place have to do with a sewage treatment plant in Truckee?? I'm Shelly Purdy, I'll tell you in tonight's Lake Tahoe Report." Anchor Intro: With so much effort put on protecting and preserving Lake Tahoe, a sewage spill could mean serious consequences to the health of the lake. Shelly Purdy takes a look at how sewage is handles in the Tahoe area on tonight's Lake Tahoe Report. ((TAKE PKG)) ((nats?? Putting camera down hole)) ((track 1)) It's an ongoing process to continuously monitor the 320 miles of sewer pipeline in the Town of Truckee. They do it using specially modified cameras. The cameras move through the pipes looking for problems. ((sot @ 16:27 Rocco Mohr, Truckee Sanitary District)) "What Herb's looking for here is any defective joints. Sags in the pipe which is a deficient grade, which can cause us problems. Damaged surface laterals which can cause unwanted flows into the pipe." ((Track 2)) Luckily leaks are rare. The bigger issue here is water coming into the system. Because the more water in the pipes, the more the sewer plant has to treat. ((s/u @ 20:20 Shelly Purdy)) "The sewage treatment plant in Truckee handles wastewater from a huge area. It even takes sewage from as far away as Emerald Bay." ((track 3)) To reduce the risk of a sewage spill into Lake Tahoe, all the sewage generated here is pumped out of the basin for treatment. The Tahoe Truckee Sanitation Agency in Truckee handles wastewater from most of the west and north shore of Lake Tahoe and the Town of Truckee. That's why it's so important to keep the system functioning properly. ((sot @ 15:24)) "We have a real aggressive metering program. Throughout we have 56 pump stations and each of those we monitor back at our office so we know the condition of those. The flows that go in and come out of each station." ((track 4)) It's just another important part of the effort to keep Lake Tahoe blue. With the Lake Tahoe Environmental Education Coalition, I'm Shelly purdy for KOLO NC8. Anchor Tag: The Truckee Sanitary District says their biggest problem with water getting into the system happens during the wintertime when snowplows hit manholes and fill them up with snow.
