LIME RESIDUALS (LIME SLUDGE) REMOVAL, HAULING, TRANSPORTATION, STORAGE, AND DISPOSAL SERVICES 2026

The lime sludge residuals covered under this agreement are generated as a by-product of the municipal lime

softening water treatment process. Residuals are mechanically dewatered using vacuum filtration dewatering

technology and are typically produced at a solids concentration of approximately 42% - 45% solids by dry weight

and is then loaded on to a truck for removal.

An estimated 18,000 wet tons of solids are processed annually.

Annual production quantities may vary depending upon treatment plant production rates, source water quality,

operational demands, weather conditions, and process optimization activities.

Residual hauling operations will normally occur during designated operating hours established by the Water

Treatment Plant; however, the City reserves the right to modify schedules, extend hauling hours, require

weekend operations, or temporarily suspend hauling operations as necessary to accommodate plant operations

and emergency conditions. At no time is the Water Treatment Plant or its grounds to be used for permanent

storage of the Contractor’s equipment or for performing work not related to the removal and transportation of

lime sludge, without express permission of the City.
