Authorize bid solicitation and contracting with the lowest responsive and responsible bidder for the procurement of National Sanitation Foundation 60 certified sodium carbonate for drinking water treatment at an estimated cost of $8,500,000


The City of Portland ordains:

Section 1.The Council finds:

  1. The Portland Water Bureau’s Improved Corrosion Control Treatment Project (Project) will further adjust the chemistry of Portland’s water to reduce potential levels of lead at the tap by making Portland’s water less corrosive to sources of lead found in some home and building plumbing.
  2. Corrosion control treatment will use two naturally occurring substances, sodium carbonate and carbon dioxide, to increase the pH and alkalinity of the water. The Project is required to comply with the Federal Lead and Copper Rule and must be online by April 2022 in accordance with an existing compliance agreement with the Oregon Health Authority (OHA). The new facilities are being constructed at the Portland Water Bureau’s Lusted Hill facility.
  3. The most cost-effective way to procure the necessary quantity and grade of sodium carbonate to ensure continuity of operations is on a long-term contractual basis. This source of supply, based on a competitive solicitation method of procurement, ensures the best value for ratepayers of the City of Portland.
  4. Based on the current estimates the cost for the purchase of NSF 60 certified sodium carbonate over a period of five years is approximately $8,500,000. The Portland Water Bureau anticipates spending up to $1,700,000 per year on sodium carbonate.
  5. The Portland Water Bureau seeks City Council’s authorization for Procurement Services to issue a competitive solicitation for purchase of NSF 60 certified sodium carbonate.
  6. A requirement of the competitive solicitation process will be that the sodium carbonate meets NSF/ANSI Standard 60 to ensure public safety and comply with federal and state drinking water regulations.
  7. Funding is available in the Fiscal Year (FY) 2021-22 Budget and will be requested in the FY 2022-23 through 2025-26 Budgets.
