Basin Installation

This is a brief reference to the recommended methods and 

procedures for installing Liberty Pumps basins to ensure that 

damage or premature failure of the basin does not occur.
This section is 

not

 intended to serve as a basic instructional guide. 

The installation of Liberty Pumps sump and sewage basins is a 

specialized skill and is assumed that the individuals who install our 

products and refer to this section will have basic understanding of 

such procedures as excavating, backfilling, pipefitting, and 

electrical work. No amount of written instruction by a 

manufacturer or regulatory agency will convert an inexperienced, 

under-supervised laborer into a skilled, experienced mechanic. 

The ability to recognize and correctly respond to abnormal 

conditions during a basin installation requires field experience as 

well as mechanical aptitude. Figure 1 is provided for reference.
In addition to proper system engineering and competent 

manufacturing, the use of basin installers who have both practical 

experience and integrity to assist that the basin be installed 

properly, constitutes the greatest protection from catastrophic 

basin failure and liability exposure.

 Basin Handling

 General Handling 

Although the exterior surfaces of the fiberglass basins are 

designed to withstand normal handling, they can be damaged 

during transportation and installation. Basins must not be 

dropped, dragged, or handled with sharp objects, and with the 

exception of the minimal movement involved in a visual 

inspection, must not be rolled.

 Unloading, Lifting, and Lowering 

 

Under no circumstances are the use of chains or cables 

around the basin shell permitted.

 

The proper way to move a basin is by lifting it, using chains or 

cables with the optional lifting lugs (not more than a 30° angle), or 

by using a non-marring sling around the basin. Before any 

attempt is made to move a basin, verify that all equipment and 

accessories have sufficient capacity and reach to lift and lower the 

basin without dragging and/or dropping. Maneuver the basin with 

guide ropes attached to the sides.

 Pre-Installation Inspection 

Confirm adherence to the project’s specifications before 

installation. Physically and visually inspected basin, pumps, valves, 

equipment, and piping materials before installation. Notify the 

carrier immediately if there is any damage. If the basin or any of its 

internal components are damaged, suspend installation until a 

determination of the extent of damage can be made by Liberty 

Pumps or its agent. Any repairs must be first authorized in writing 

by Liberty Pumps and then be done in accordance with Liberty 

Pumps instructions.

 Storage 

Store the basin in a secure, controlled area where the potential for 

accidental damage or vandalism will be minimized. The storage 

area must be free from sharp objects, rocks, and any other foreign 

solutions or materials that could cause damage to the basin. 

Chock the basin until it is needed for installation and, if windy 

conditions are possible, secure the basin with non-marring 

restraints of a size and number adequate for securing the basin.

 Excavation

 

Locate all overhead and underground utilities before 

excavating.

 

 Excavation Considerations 

The excavation must provide adequate space for the basin, piping, 

and other buried equipment, and for the replacement and 

compaction of backfill materials particularly around the basin 

walls. The size, shape, and wall slope of the excavation should be 

determined by soil conditions, depth of excavation, shoring 

requirements, and if workers are required to enter the excavation, 

safety considerations and federal, state, county, and municipal 

regulations.

 Excavation Location 

Excavation for an underground basin must be made with due care 

to avoid undermining foundations of existing structures and 

contact with underground utilities. In the absence of building 

codes or regulations, maintain a minimum distance of 5 feet plus 

a slope of 45° from the bottom of the compacted sub-base to the 

bottom of the adjacent structures, foundations, footings, and 

property lines. Additional distances may be required to ensure 

that any loading carried or created by the foundations and 

supports cannot be transferred to the basin.

 Maximum Basin Burial Depth 

If burial depth is greater than the basin height, contact Liberty 

Pumps to determine if additional wall reinforcement is required 

and secure written authorization.

 Excavated Materials Handling 

Carefully store excavated materials, that cannot be removed from 

the job site, as far from the edge of the basin excavation as 

possible. Unless approved for use as backfill, securely store 

excavation materials separate from the approved backfill 

materials.
