Approved List of Materials and Suppliers for Sewer Construction
The approved list of materials and suppliers for sewer construction has been compiled by the Construction Division of the Engineering Department. Additions and deletions are made continuously. In between updates of the online list, contractors pre-qualified with MSD will be notified in writing when a material or a supplier has been removed from the list. When a new material or supplier has been approved, a copy of the approval letter from MSD to the manufacturer or supplier may be used as evidence of acceptability.
The date at the top of the title page indicates when the online version of the approved list was last updated. The date that each category was last dated is indicated below.
