SECTION 33 30 02 Page 18

3.2.9 Bypass Pumping

If pumping is required, an identical standby pump shall be on site in the event of failure of the primary pump. The standby pump shall include its own bypass piping system or shall be connected to the primary bypass piping system, so the standby pump can immediately be placed into service when needed. All pumps shall be sound attenuated to 68 dBA at 23 feet .

The bypass pumping system must be continuously monitored by the Contractor at all times bypass pumping is occurring. This includes 24-hour monitoring when no work is being performed. If at any time during construction, effluent from the existing sewer is not fully contained by the bypass system, gravity service will be restored by a temporary tie to the new construction and work shall be suspended until the problem is resolved to the satisfaction of the Engineer. All bypass pumping and piping operations shall be installed a minimum of 2 feet above the 100-year flood elevation.

Plugging or blocking of sewage flows shall incorporate a primary and secondary plugging device for 15 inches up to 30-inch diameter pipe. When plugging or blocking is no longer needed for performance and acceptance or work, it is to be removed in a manner that permits the sewage flow to slowly return to normal without surge, to prevent surcharging or causing other major disturbances downstream.

The Contractor shall tie-off and/or anchor temporary plugs used in the bypassing of flow such that plugs are not able to proceed into downstream piping.

During any bypass pumping operations, signage and emergency contact information must be clearly visible at the bypass pumping operations site.

Sustained bypass pumping operations (operations exceeding 24 hours) will require installation of an auto-dialer, even if the operation is continuously monitored by a person.

Contractor shall provide a temporary cast iron or steel cover over the bypass pumping suction manhole and discharge manhole to safeguard the manholes, to prevent inflow and to minimize odors. At the discharge manhole, the Contractor shall route the discharge piping down into the manhole and shall install 90-degree bends on the end of the piping to direct the flow out of the discharge manhole and heading downstream. The piping arrangement shall be such that the flow is not vertically directed. This piping arrangement will help to direct the flow and minimize turbulence (and odors) in the discharge manhole.

The Contractor will be required to submit, for approval by the Engineer, a detailed plan of the method the Contractor proposes to maintain the existing flow during construction. The bypass pumping plan must include a provision for handling the existing peak flow by pumping or bypassing by gravity. At a minimum the following items must be included with the submittal:

1. Number of pumps including pump manufacturer data and pump curves. A backup pump(s) must be provided such that the peak bypass flow can be maintained with the largest pump out of service.

2. The primary and standby pumps shall be piped so no changes in piping are required to switch between pumps. Automated controls are required to switch between the primary and standby pump(s).

SECTION 33 30 02 Page 19

3. Provision for manned 24-hour monitoring, as long as bypass pump is in operation.

4. Site plan showing location of bypass pumping operations, suction manholes, discharge manholes, bypass piping layout/alignment, and access. The layout shall include the profile, including 100-year flood elevation, the pump elevations, manhole rim elevations, invert elevations, bypass piping profile -- on grade or trenched installation.

5. Expected duration of bypass pumping operations.

6. Location and number of proposed tie-off and/or anchors used to prevent movement or blowouts for plugs.

Upon approval of the plan, and prior to initiating bypass pumping operations, the Contractor will be required to verify his method of handling sewer flows during construction by pumping at peak flows for four

(4) hours for each pump. Testing shall include verification of automated controls, automated switch to standby pump, and auto-dialer operations.

This test must be witnessed by the Contracting Officer.

The Contractor will be required to perform bypass pumping operations during dry weather, unless otherwise authorized by the Contracting Officer.

If a failure of bypass pumping operations occurs, the Contractor shall be responsible for any fines levied as a result of effluent reaching creeks and waterways.

Flow from all connecting sewers must be accommodated. Bypass piping for connecting sewers 8-inch to 12-inch may utilize lay flat hose. Bypass piping for connecting sewers 15-inch to 30-inch shall utilize hard piping and must have primary and standby sound-attenuated diesel auto-priming pumps. If connecting to the main bypass discharge line, the connection must have an isolating gate valve.
