<br />CITY OF SUNNY ISLES BEACH SECTION 02761 - 1 <br />CLEANING STORM SEWER SYSTEMS <br /> <br />SECTION 02761 <br /> <br />CLEANING STORM SEWER SYSTEMS <br /> <br /> <br />PART 1 - GENERAL <br /> <br />1.1 SCOPE OF WORK <br /> <br />A. The Work covered in this section consists of cleaning storm lines and manholes prior <br />to the internal television inspection(s). <br /> <br />B. Gravity Main and Lateral Cleaning: The intent of gravity main cleaning is to remove <br />debris that may be causing a reduction in flow capacity, potential storm backups, or that <br />limits the ability to evaluate the structural condition of the pipe segment. On all storms, <br />the Contractor shall perform storm-cleaning work to an acceptable level as necessary <br />to perform a thorough television inspection. An acceptable level is defined as the <br />removal of all debris throughout the pipe segment cleaned. If the pipe condition is <br />such that cleaning may cause a potential collapse, then the pipe shall be televised <br />without attempting to clean it pending approval by the Owner. <br /> <br />C. Water for Cleaning: The Contractor will be responsible for obtaining a transient water <br />meter and paying for water used during course of cleaning. <br /> <br />D. Recovering of Equipment: The Contractor will be responsible for recovering any <br />equipment that becomes lodged or lost in the pipeline. The Contractor will be <br />responsible for all costs associated with required evacuation, restoration of roads, <br />right- of-ways and easements, and repairs to pipes and manholes as needed to <br />restore the pipeline and appurtenances back to their original conditions. <br /> <br />1.2 CLEANING EQUIPMENT <br /> <br />A. Hydraulically Propelled Equipment: The equipment used shall be of a movable dam <br />type and be constructed in such a way that a portion of the dam may be collapsed at <br />any time during the cleaning operation to protect against flooding of the storm. The <br />movable dam shall be equal in diameter to the pipe being cleaned and shall provide a <br />flexible scraper around the outer periphery for grease removal. Special precautions to <br />prevent flooding of the storms and public or private property shall be taken at all times. <br />
