(Apple Valley)– For the first time in more than five years, wastewater from Apple Valley is flowing through a permanent interceptor, or sewer line, to VVWRA’s main treatment plant in Victorville.
The newly completed interceptor was opened for wastewater flow in mid-February and marks another major milestone toward the completion of the Upper Narrows Pipeline Replacement Project. The new interceptor features two 16” pipes that connect to the 30” existing line in an area east of the Mojave River. The 16” pipes stretch more than a third of a mile and go 42 feet under the Mojave River. At Kemper Campbell Ranch, they join a large pipeline drilled through the rocky hills of the Upper Narrows.
Another pipeline that will carry wastewater from Hesperia, Spring Valley Lake and portions of Victorville is being installed under the BNSF railroad tracks. It will tie into the same large pipeline in the Upper Narrows. Construction on that portion of the interceptor system is expected to be completed in June. The Upper Narrows Pipeline Replacement Project became necessary in late 2010 after a series of powerful storms severely damaged the existing pipeline that ran along the Mojave River. An emergency bypass was constructed in just 9 days. The new, permanent interceptor project was designed to avoid environmentally sensitive areas as much as possible.
The cost of the Upper Narrows Emergency and the Pipeline Replacement projects is estimated at $41 million. The Federal Emergency Management Agency (FEMA) is paying for the majority of the repair cost.
