1. City projects involving sanitary sewer lateral CIPP (cured-in- place-pipe) lining work are active and in the construction phase in your neighborhood. The construction phase itself is a muti-step process that involves different construction contractors , work crews and work types over different non-continuous time periods. Lateral lining only occurs after City sewer mains have been CIPP lined (which itself is a muti-step process but less invasive to the homeowner). A general process of steps involved in CIPP lateral lining follows:

Step-1: generally involves CCTV (closed circuit television) inspection, sometimes pre-cleaning where necessary, of the City’s sewer main and publicly owned portion of sewer laterals (the segments that connect to the homeowners privately owned portion of the sewer at the right of way line) for the segments that are planned to be CIPP lined. Step-1 is performed by crews using vans/trucks, televising equipment, and other cleaning trucks and equipment designed to collect the data for the City to determine if lining is possible, and if not, what other rehabilitation work is required.  There is no disruption to flow, service, or excavation during Step-1.  However, crews may need access to rear/side yard easements if a sewer is located in an easement.

Step-2: (Excavation Step) Where CIPP lining is deemed feasible, clean-outs are constructed adjacent to the property/ or easement line to enable CIPP lateral lining to be performed.  Clean-outs are City owned access structures necessary for this type of lateral lining.  They provide an inspection and cleaning port for this work and any future maintenance work at the point of connection where the City has ownership of the sewer lateral. This work is disruptive and involves excavation, but is minimal compared to the excavation and cost that would be necessary to replace the entire publicly owned portion of the sewer lateral (from main to property/easement line). In some cases, lining is not possible, and replacement of the entire lateral or more extensive repairs are needed. Defects that often occur at or near the transition between the public /private sewer are corrected during this step.  If crews encounter defective pipe on the private (customers) side, customers are typically notified directly and encouraged to have a plumber inspect and correct private-side-defects.  Construction crews are required to notify residents of impending work in the adjacent right of way that would cause a disruption 7 days in advance. Usually one notice is issued that covers periods of discontinuous work related to the same project, but different contractors will notify separately for their particular phase of work. Restoration (driveways, sod, pavers, fencing, sprinklers, etc.) of the area involved should be put back to as- good or better condition than prior to the work. Sometimes it is necessary to remove larger landscaping within the City right-of-way/easement to enable this work, and the homeowner is responsible for replacing these items (although it is not a good idea to plant large trees over or near a sewer line).  We make every effort to accommodate special situations where we can.

Step-3: Final cleaning/CCTV, CIPP lateral lining, and post CCTV inspection is performed by specific crews configured to perform this work. This work involves short disruption in service to the homeowner, but no excavation. Multiple trucks, labor , and ancillary equipment is involved, as well as MOT (maintenance of traffic) and access to City owned structures in the right of way including manholes and clean-outs. When lining is complete, a post CCTV inspection confirms the acceptability of all work.
