STAFF REVIEW: Eddie A Ramos, Water Treatment Plant Superintendent SIGNATURE,
APPROVED BY CITY ADMINISTRATOR: Tia Messino SIGNATURE
As part of the City’s water treatment process, hydrated lime is used to treat and soften the raw water.
When the lime bonds with targeted minerals (i.e., radium, calcium, magnesium, etc.) sludge is generated.
The sludge is transferred to three exterior holding lagoons until contractually removed. Typically, the
removal takes place on a bi-annual basis and the waste is taken to a landfill. The last such project was
completed in late 2023.
To provide cost savings, City staff have been exploring the idea of land application of the lime sludge. For
consistent budgeting purposes, staff intends to remove lime sludge from one of the three lagoons
annually. Based on the lab results, the City’s lime sludge meets the criteria for land application. Plans
and bid specifications were prepared for a base bid using land application option and an alternate bid for
the landfill option.
A Notice to Bidders was advertised in the Daily Herald as well as on an online bidding platform
QuestCDN on July 8, 2025, and sealed bids were opened on July 29, 2025. There were three bids
received. The results are below.
