Title
Purchase Supply of Silica Dioxide - Amendment 3 (Ordinance S-47139)
Description
Request to authorize the City Manager, or his designee, to execute an amendment to Agreement 143832 with Thatcher Company of Arizona to provide additional funding to the contract. Further request to authorize the City Controller to disburse all funds related to this item. The additional expenditures for goods included in this agreement will not exceed $50,000.
Report
Summary
The purpose of this agreement is to provide the Water Services Department (WSD) Deer Valley Water Treatment Plant with an additional supply of Silica Dioxide.
This amendment is necessary to accommodate a previously-approved price increase that took effect Nov. 2019 as well as the extended term of the Agreement. Without a supply of Silica Dioxide for the Deer Valley Water Treatment Plant, WSD would lack the ability to filter out particles and other solids from treated drinking water.
Financial Impact
The initial agreement for the Silica Dioxide Contract was executed for an expenditure not-to-exceed $186,000. Amendment 1 extended the contract term from Nov. 1, 2019 to Oct. 31, 2020, and increased the price of Silica Dioxide from $380 per ton to $476 per ton. Amendment 2 extended the contract term from Nov. 1, 2020 to Oct. 31, 2021. Amendment 3 will increase the agreement by an additional $50,000, for a new total not-to-exceed agreement value of $236,000.
Funding is available in the Water Services Department's Operating budget.
