On July 3rd, 2017, the Commission approved a Contract with Central Salt-Lyons for 100 tons of salt at $41/ton.  I reported the unit price in error, the contract unit price was $41.20/ton.  The Contract is valid through this winter.  I am bringing this back to Commission to have it approved in 2018, for the remainder of the winter.  We received an invoice dated 1/21/18 in the amount of $1,068.32 that we need to pay.

Motion to approve the purchase of an Oztec Gas Concrete Vibrator with 7' shaft and steelhead from Lewis Contractor Sales for a cost not to exceed $1,480.00.

We need to replace our concrete vibrator at the Street Department.  The concrete vibrator consolidates concrete, eliminating air pockets to make longer lasting and more durable concrete.    We received a quote from Lewis Contractor Sales for an Oztec Gas Concrete Vibrator with 7' shaft and steelhead for $1,480.00.

Motion to approve the purchase of 4 totes of Cationic Polymer from Fort Bend Services, for a cost not to exceed $13,984.00 delivered.

Polymer is used at the WWTF to chemically break the bond between sludge and water, allowing them to separate.  This process is called flocculation.  We received a quote from Fort Bend Services, Inc. to purchase four (4) 2,300 lb. totes of cationic polymer for id="mce_marker".52/lb for a total cost of $13,984.00 delivered.  We receive a price break if we order at least 3 totes. 

Motion to approve the repair and rehabilitation of five sanitary sewer manholes by Mayer Specialty Services, Goddard, KS, for a cost of $750 per manhole and a single $600 mobilization charge, for an amount not to exceed $4,350.00.

WWTP has identified five sanitary sewer manholes in need of reconstruction of the "bench" portion of the manhole.  The bench includes where the flow goes through the manhole at the bottom, typically made of concrete and/or brick, which deteriorates over time.  When the manhole bench fails, raw sewage can infiltrate into the ground around the bottom of the manhole.  This can undermine the structural integrity of the manhole itself resulting in complete failure of the manhole, major sewer backups, as well as contamination of the soil around the manhole with raw sewage.  We received a quote from Mayer Specialty Services, Goddard, KS, for a cost of $750 per manhole and a single $600 mobilization charge for a total of $4,350.
