| | | | | | | | I. RECOMMENDATION:
Council Approval to Purchase and Install Three (3) Electrolytic Cells for the On-Site Hypochlorite Generator (OSG) at the Water Treatment Plant in the amount of $64,469.00.
II. BACKGROUND:
The City Water Treatment Plant uses an on-site hypochlorite generation system (OSG) to produce chlorine-based disinfectants where a solution of sodium chloride is passed through an electrolytic cell. This process converts the chloride ions present in the solution to either sodium hypochlorite or mixed oxidant solution, depending on the cell configuration. The casing of the OSG has cracked and leaking solution and has possibly damaged the electrolytic cells which most likely will need to be replaced.
III. DISCUSSION:
Staff will be having the casings and cells inspected and then will make the determination to have them replaced if there are signs of significant damage. The urgency of this is that the hypochlorite generators are currently down and operators are currently manually mixing the solution to ensure we continue to deliver safe and reliable drinking water. If all cells need to be replaced this authorization will allow the City to proceed with the ordering and installation of the three (3) CT-100 Cells to ensure that the OSG continues to operate in the future and water demand increases into summer. The City will purchase the three (3) cells from Telstar Instruments who conducts all the regular scheduled maintenance on these instruments.
IV. ALTERNATIVES:
None at this time. This is an urgent item to ensure the continued delivery of safe and reliable drinking water.
V. FISCAL IMPACT:
This purchase will come from the water plants marjory machinery and equipment fund which has sufficient funds to support this unanticipated purchase. Total contract amount will be $64,469.00. | | |
