These are the main points to take into consideration when installing a wastewater treatment plant:




Advice to the user, compliance with requirements and final control

Earthworks companies must follow legal requirements. See here the summary (in French). 
Beyond these requirements, earthworks companies must follow manufacturer’s instructions and give use and maintenance instructions to the final user.



Installation of the WWTP

The WWTP must be placed outside the building and its location should consider (non-exhaustive list):
- how to access the construction site;
- the wastewater discharge distance;
- how to access the WWTP to desludge and maintenance it;
- the topography;
- the sewage disposal.

All these installation constraints but also soil type may have influence on the WWTP to choice. Please see the following examples:

 Handling is very important
Use lifting chains


- Chains having equal length
- Chains length ≥ tank diameter
 
Importance of the foundation

- Stable and horizontal base
- Adapted foundation
    
 Installation adapted according to the resistance of the tank
           
Always verify the maximal load accepted by the tank
   
Installation adapted according to the tank resistance
          
Installation according to the real load
 
   
 Backfill
          
Rackfill using rock-free earth
    
 After backfill 

Always fill the tank with water tank after backfill
