• All lining material shall be suitable for use in domestic sewers.

• It shall be assumed that pipelines to be rehabilitated will need cleaning. Pipelines may require removal of protruding services and by-pass pumping to successfully install the liner system. If the Contractor feels point repairs are necessary to complete lining of a particular main line segment, the County may either instruct the Contractor to make the individual necessary repairs, make the repair using County staff, or cancel that section of work at no cost to the County. The Contractor shall be responsible for all material removed from the pipeline and shall properly dispose of materials in accordance with the appropriate regulatory agency requirements and shall supply documentation of conformance to these requirements.

• Any main line or service line damage occurring during the rehabilitation process shall be the responsibility of the Contractor including, but not limited to, point repairs, main line replacement, service line replacement, any and all required permits, traffic control, and bypass pumping, including a back-up system and restoration of all disturbed areas. The Contractor shall be responsible for any wastewater or cure water spills during any operations and pay any and all fines, fees, property damage, environmental damage and cleanup costs that are associated with wastewater spill.

• All work shall be done in compliance with NPDES.

• Proper Erosion and Sediment control best management practices will be utilized on all projects. See Pinellas County Utility Technical Specifications, Stormwater Pollution Prevention Plan, and Erosion and Sediment Details.

QUALITY CONTROL

Products and Installers seeking approval must meet all the following criteria to be deemed acceptable:

• The cured-in-place pipe must have a minimum design life of 50 years. The minimum design life may be documented by submitting life estimates by national or internally recognized authorities or specifying agencies, to the County Representative. Otherwise, long-term testing and long-term in-service results may be used and results extrapolated to 50 years.

• Acceptable products shall provide documented acceptable wastewater and stormwater installations in the United States for the sizes indicated in the bid sheets.

• Liner materials shall be as specified in the Material Specification Manual.

SUBMITTALS

The Contractor shall submit the following information:

• Manufacturer’s certification that the materials to be used meet the referenced standards and these specifications.
