SUBJECT
Title
Award of Contract for Wastewater Treatment Chemicals for the Water Pollution Control Plant (F15-87)
Report
REPORT IN BRIEF
Council approval is requested to award a one-year contract in the amount of $750,000 to Polydyne Inc. of Riceboro, Georgia, for the purchase of Polymer for wastewater treatment processes. Approval is also recommended to delegate authority to the City Manager to renew the contract for up to five additional one-year periods, subject to available funding, acceptable pricing and service, and the City's participation in the Bay Area Chemical Consortium (BACC) regional purchasing cooperative described below. Finally, authorization is requested to increase the contract within budgeted appropriation limits if additional quantities are needed.
These recommendations are consistent with those approved by Council in 2014 for the purchase of Sodium Bisulfite and (small amounts of) Sodium Hydroxide, other chemicals used in wastewater treatment processes. Aligning multiple chemical purchases with the BACC will create bidding efficiencies and result in volume pricing discounts over the next several years.
EXISTING POLICY
The City may utilize purchasing cooperatives pursuant to Section 2.08.220 of the Sunnyvale Municipal Code.

The Sunnyvale Water Pollution Control Plant (WPCP or Plant) uses several chemical products to treat wastewater, including but not limited to Polymer and Sodium Bisulfite.
Polymer flocculants are organic chemical compounds used in the tertiary processing of wastewater at the WPCP. The polymer bonds with solids that are dissolved with the secondary effluent to create larger particles that settle out of suspension. The solids can then be collected. Removal of suspended solids and turbidity from the wastewater stream is necessary to meet effluent limitations and other requirements of the plant's discharge permit and sta...
