The Sewer Design Section of the County Sanitation Districts (CSD), is a confederation of 24 special districts that provides wastewater conveyance, treatment and disposal services to most of the County, including the City of Long Beach. Sanitation district boundaries are based on topographic, not political, boundaries so the City of Long Beach is served by several of our sanitation districts – specifically, County Sanitation Districts Nos. 1, 2, 3, 8 and 19. The Board of Directors of each sanitation district is comprised of the mayors of the cities served by that district. Thus, Mayor Robert Garcia is on the Board of Directors of County Sanitation Districts Nos. 1, 2, 3, 8 and 19.
County Sanitation District No. 2 owns and maintains a 10,400-foot long, 63-inch diameter sewer that runs along 65th Street (from Cherry to Myrtle), then west through Jordan HS and Villa Park, and then south through Villa Park and De Forest Park. See the attachment below for sewer alignment. The sewer was constructed in 1927 and is in need of repair. Rather than construct a new sewer (which would be very disruptive and costly), CSD intends to rehabilitate the existing sewer by “sliplining”, which involves inserting 10-foot long segments of plastic pipe inside the existing pipe. This is done by excavating approximately 15-foot wide by 30-foot long pits every few thousand feet along the sewer alignment so that it is possible to access and remove the top of the sewer pipe and insert the plastic pipe inside. See attachment for proposed location of pits. A special machine inside the pit then joins and pushes the segments of plastic pipe upstream and downstream through the sewer. The work is performed while there is flow in the pipe, so sewer service is not interrupted.
The construction drawings and specifications for this project are currently at 90% design completion. Anticipated advertising of the project is expected to occur in May and recommended that the Board of Directors of County Sanitation District No. 2 award the project to the selected contractor in August. Construction is anticipated to start in late 2016 and conclude in late 2017. Please note that sewer projects are linear in nature, so the work will progress from one area to the next – the work won’t be in one location for the entire project duration.
Prior to the start of construction, CSD's contractor will obtain the necessary encroachment/excavation permits from the City’s Department of Public Works and submit a Traffic Control Plan for the City’s review and approval. Temporary no parking signs will be posted in accordance with City requirements. Measures will be taken to minimize disruption to residents and motorists. According to my discussions with the City’s Department of Public Works, standard working hours (7:30 am to 3:30 pm, Monday to Friday) will be permitted for this project. Construction at each pit location is anticipated to take anywhere from 1 to 3 months depending upon the challenges unique to each location.
The hired contractor will conduct a preconstruction meeting at least 2 weeks prior to the start of any work and invite all interested/affected parties (City inspectors, District 9 staff, Jordan HS staff, utilities, etc.) to discuss the project schedule, sequence, duration, traffic control, and other details.
