Bypass Pumping Sample Clauses
The Bypass Pumping clause outlines the requirements and procedures for temporarily diverting the flow of liquids, typically wastewater or stormwater, around a work area during construction or maintenance. This clause specifies the contractor’s responsibility to provide, install, operate, and maintain pumps, piping, and related equipment to ensure uninterrupted service while the main system is out of operation. By establishing clear expectations for managing flow during critical work, the clause helps prevent service disruptions, environmental contamination, and potential damage to infrastructure.
Bypass Pumping. Provide bypass pumping for the flow of sewage around the section or sections of pipe designated for renovation. Accomplish bypass pumping by plugging the line at an existing upstream manhole and pumping the flow into a downstream manhole. Pump sizing shall be adequate to handle the flow. Provide bypass pumping during pre-installation and post-installation video inspections and during the CIPP liner installation.
Bypass Pumping. 1. The Contractor shall provide sewage bypassing arrangement plans to the Service Authority at least 72 hours prior to commencing work on each portion of the system. The plans must be specific and complete, and shall include, but not be limited to, the following details:
a. Provide justification that bypass plan is sufficient to accommodate existing flows.
b. Capacities of pumping equipment.
c. Road crossing details, including paved or unpaved roads, driveways, entrances, or other travel ways.
d. Protection against pipe breaks.
e. Sewer plugging methods and bypass time duration for each sewer section.
f. Size, length, material, and method of installation for suction and discharge piping.
g. Method noise control for each pump and/or generator.
h. Bypass pumping locations.
i. Bypassed flows must be discharged to the sanitary sewer system, appropriate watertight vehicle or appropriate watertight container.
j. The Contractor shall prepare/set up sewage pumping/bypass system prior to beginning work on any sewer pipeline or manhole activities. The system shall be activated when necessary to bypass flows for blockages resulting from the Contractor’s activities in the vicinity of the sewer system.
k. The pumping/bypass system shall be adequate in size to handle the flows in the system being worked on. The Contractor shall supply the necessary pumps, conduits, engines and other equipment to divert the flow of sewage as appropriate.
l. In order to prevent the accidental spillage of flows, all discharge systems shall be temporarily constructed of pipe with positive, restrained joints. Under no circumstances will aluminum “irrigation” type piping or glued PVC pipe be allowed.
m. The Contractor shall make all arrangements for by-pass pumping during the time when the sanitary sewer main is shut down for any reason.
n. Ensure that all pumps and equipment employed by the Contractor are continuously monitored by an individual who is trained and qualified to start, stop, refuel and maintain this equipment during the work being performed by the Contractor. The Contractor shall select pumping/bypass equipment that will not have excessive noise levels from a maximum of sixty decibels (60 dB) at a distance of fifty (50) feet.
o. The design, installation, and operation of the temporary pumping system shall be the Contractor’s responsibility. The by-pass system shall meet the requirements of all codes and regulatory agencies having jurisdiction.
p. The Contractor shall ensure tha...
Bypass Pumping. The plan shall contain at a minimum the following:
1. Activity
2. Desired Rate in gallon per minute (gpm).
3. Size and location of manholes or access points for suction and discharge hose or piping.
4. Size of pipeline or conveyance system to be bypassed
5. Number, size, material, location and method of installation of discharge piping
6. Bypass pump sizes, capacities, and number of each size to be provided onsite including all primary, secondary, and spare pumping units.
7. Downstream discharge plan.
8. Any temporary pipe supports and anchoring requirements.
9. Contractors plan for providing continuous monitoring of the bypass pumping operation as well as the monitoring persons’ qualifications.
Bypass Pumping. The CONTRACTOR will provide submittals for the by- pass pumping plan and those plans approved no less than two weeks prior to execution of the work. The CONTRACTOR will not mobilize prior to approval of the pumping plan.
