The following delivery methods may be used in the delivery of this standard: 

  • classroom 
  • a blend of classroom and e-learning 
  • onsite 

This standard is considered to contain 51% or more practical training. 

This standard is considered to be set at a basic/entry level. 


For the successful completion of training, candidates must complete a multiple-choice question and answer assessment. 

Quality assurance 

Quality assurance against this standard will require initial approval of the training organisation and their content mapped to the standard.  

CITB will also conduct an approval intervention, either desk-based or centre visit, to ensure the training organisation can meet the requirements of the training standard.  

Approved training organisations (ATOs) will be required to present information on records of training and assessment upon request to CITB for desk-based analysis. They will also be visited annually by the CITB quality assurance team. 


There are no mandatory renewal or recommended refreshment requirements for this standard, however candidates are expected to continue to upskill with new products and techniques

design in accordance with the current standard BS 8120:2009 - The Code Of Practice For The Protection Of Below Ground Structures Against Water From The Ground and other reference documents 

Understand and explain health and safety implications and considerations 

including when:  

  • installing the system  
  • using hammer drills  
  • using Stanley knives  
  • using tower scaffolds  
  • working in confined spaces  
  • using mechanical or passive extraction equipment.

Carry out pre-installation preparation and checks 


  • checking the areas of installation and assessing the need for further prep work  
  • ensuring the prep has been carried out 
  • identifying the need for further prep work such as making good and repairing defects. 

Understand and explain pump design 


  • a basic understanding of a pump and how to correctly design a pumping system specific for the project  
  • a brief look at alternative pumps such as low level, wastewater, and sewage.
