Invitations to Bid 

The Solid Waste Disposal Authority (SWDA) is bound by purchasing laws which are set forth by the State of Alabama and the SWDA Policies.

Depending on the amount of the purchase, SWDA uses various types of buying mechanisms as follows:

• Informal Bids I ($1,000 - $3,000)
  • Quotations from a minimum of three vendors obtained verbally or in writing. (All must be documented/attached to the Purchase Order).
• Informal Bids II ($3,001 - $10,000)
  • Quotations from a minimum of three vendors obtained verbally/emailed or in writing. (All must be documented/attached to the Purchase Order).
• Informal Bids III ($10,001 - $29,999)
  • Three written quotations. (All must be documented/attached to the Purchase Order).
• Formal Bids ($30,000 or more) & all Capital Projects
  • The Purchasing Agent may advertise, if deemed necessary, on the SWDA website, and/or in a local newspaper of general circulation to obtain good competition. Notice of bids for commodities/services are sent to all Vendors on the Bidders List.
