APPROVED BY: Esperanza Colio Warren, City Manager Esperanza Colio Warren, Cily Manager Cera Cle Wan REVIEWED BY: Sandra L. Fonseca, Interim Finance Director PREPARED BY: Guillermo Sillas, Public Works Director/City Engineer SUBJECT: Authorize the City Manager to Issue Purchase Order to Parkson Corporation in the Amount of $128, 164.75 for the Reconditioning of the Bar Screen located at Wastewater Treatment Plant.
==============
Recommendation:
Authorize the City Manager to issue Purchase Order to Parkson Corporation in the amount of $128,164.75 for the reconditioning of the Bar Screen located at Wastewater Treatment Plant.
Background:
Back on April 19, 2005, the City Council of the City of Calexico accepted the bid proposal from NEWest Construction in the amount of $925,934.00 for the Wastewater Treatment Plant UV Disinfection and Bar Screen Project. The Bar Screen was manufactured by Parkson Corporation and its purpose is to filter and remove big solid objects from the wastewater. It's a type of coarse screen that takes out rags, plastics, papers, metals, etc. from any flowing water.
Discussion and Analysis:
The existing Bar Screen is over 18 years old and is in major need of repair (see picture below); therefore, City staff is recommending that the City Council of the City of Calexico authorize the City Manager to issue purchase order to Parkson Corporation to recondition the Bar Screen located at Wastewater Treatment Plant. The reason City staff is recommending that the City work directly with Parkson Corporation is because they manufactured the Bar Screen, and they can directly connect to the existing piping at the Wastewater Treatment Plant without any modifications.

1. to preserve or protect life, health or property; or
