Independence Rock Creek Wastewater Treatment Plant Sludge Thickening Improvements

The City of Independence is soliciting a single‑prime, lump‑sum contractor to execute sludge‑thickening upgrades at the Rock Creek Wastewater Treatment Plant. Scope includes demolition of existing dissolved‑air‑floatation units, installation of new rotary‑drum thickeners with polymer feed and transfer pumps, associated electrical upgrades, piping modifications, new HVAC systems, and interior painting. The work requires demolition, mechanical/electrical installation, control‑system integration (Allen‑Bradley PLCs, HMI panels), testing, commissioning, and a ten‑day field‑service period for start‑up and training. Bids are submitted online via PublicPurchase; a non‑mandatory pre‑bid conference is scheduled on‑site. Performance bonds, payment bonds, and a 5 % bid guarantee are required.
