AW Standard Product Lists (SPLs) specify acceptable manufacturer products for use in the construction of water, reclaimed water and wastewater facilities. These products have undergone stringent testing to ensure safety, reliability and consistency within the AW system. The Current AW SPLs are updated on a quarterly basis and Previous AW SPLs are also available.

Standard Products Lists (SPLs) Uses


Design engineers should confirm that products on the AW SPLs meet their project needs. If the project requires products of different size, material, or design, seek approval from AW for substituted or alternative products.


Contractors should confirm that construction contract documents allow for use of products on the SPLs. If the product is not on a current SPL, the contractor must submit manufacturer technical data sheets of sufficient detail to adequately describe the product or materials to be used.


To expedite the review of products, contractor submittal reviewers should confirm the product:

  • meets the functional needs of the project
  • is the type specified for use on the project
  • is in the category covered by the SPL
  • manufacturer is listed on the SPL
  • is within the size range listed on the SPL
  • model number, serial number or manufacturer designation is listed on the SPL
  • meets all requirements in the Description on the SPL
  • meets all requirements given in the Notes on the SPL
  • meets all requirements in the specifications, special provisions, details and construction notes in the project contract documents

The following instructions are provided to manufacturers and vendors who wish to have one of their products reviewed by AW for listing on a current SPL.  Only SPL applications for one (1) product that meets every technical requirement of a corresponding and current AW SPL will be accepted and reviewed. 

Applications received for more than one product, a product line, or a catalog of products will not be reviewed.  Similarly, applications submitted for a product that does not meet every requirement of a current SPL will also not be reviewed.

STEP 1:  Confirm the product complies with the requirements of a current SPL.  Once an SPL is identified for the product, download the AW SPL Application Form and Checklist

STEP 2:  Compile the SPL Application Form, Checklist, and supplemental documentation specific to your product / SPL into one (1) .pdf email attachment. The supplemental documents contained within the .pdf attachment shall be tabbed and follow the order of the Checklist items.  If any of the Checklist items are not applicable, provide an explanation.

STEP 3:  Submit the completed SPL Application to  Your email should contain only one .pdf attachment: the completed SPL Application Form, Checklist and supplemental documentation as described in Step 2.  In the subject line of the email, enter the “Company Name”, "Product Name", and the applicable "SPL Number".  Upon receipt, AW will perform an initial review of the application and provide comments within 30 days.  Once the application is complete, it will be reviewed by the AW Standards Committee.  SPLs are updated on a quarterly basis.
