Water & Wastewater Treatment Equipment Serving Cincinnati, OH
Precision lime slaking, biosolids stabilization, drying, storage, and truck loading systems engineered by RDP Technologies for Cincinnati and Greater Cincinnati municipal facilities.
Trusted Process Equipment for Cincinnati Water & Wastewater Plants
For over 45 years, RDP Technologies has been building robust equipment, backed by dependable process performance, based upon a foundation of practical technologies that simply perform. Cincinnati-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.
Biosolids Storage & Precision Truck Loading Systems
Metropolitan Sewer District of Greater Cincinnati (MSDGC) operates seven wastewater treatment plants across Hamilton County, anchored by the Mill Creek Wastewater Treatment Plant and the Little Miami Wastewater Treatment Plant. Combined daily biosolids production across these facilities is substantial, with material moving to land application, composting, and other beneficial reuse outlets across southwest Ohio and northern Kentucky. Reliable storage and loadout equipment keeps that program running consistently through hot, humid Ohio Valley summers and harsh winters that can compact and freeze sludge in conventional hoppers. RDP Technologies engineers biosolids storage systems and precision truck loading systems that automate the full flow from dewatering through to the departing truck.
Moving floor technology built into live bottom bin storage keeps sticky sludge cake flowing reliably regardless of season, eliminating the bridging and rat-holing common to conventional steep-walled hoppers. Sludge cake truck loading runs automatically through the precision truck loading system, with most loads completed within minutes and held to within a couple hundred pounds of the operator’s target weight.
Three decades and approximately three hundred biosolids conveying equipment installations have refined a layout that keeps trucks clean, departure times predictable, and operator involvement minimal at the bay. Because the cycle runs without continuous attendance, Cincinnati-area plant staff can redirect labor toward higher-value work elsewhere in the facility. For utilities managing complex multi-plant scheduling and consent decree compliance pressures, that automation directly improves daily throughput and frees up operations resources for higher-priority work.
Biosolids Lime Stabilization & Pasteurization Solutions in Cincinnati, OH
Cincinnati’s wastewater system operates under one of the largest active federal consent decrees in the country, with MSDGC committed to a multi-decade capital program addressing combined sewer overflows and broader treatment infrastructure improvements. That capital pressure, paired with Ohio EPA oversight under federal EPA 503 standards, has kept biosolids strategy near the top of long-term planning conversations across the region. RDP Technologies has been delivering EPA 503 compliant lime-based solutions since the federal rules were first established, supporting both Class A biosolids treatment and Class B biosolids stabilization at facilities across the Ohio Valley.
The EnVessel Pasteurization biosolids pasteurization system is one of the most widely deployed Class A processes nationally, with more than 70 installations operating across the United States. EnVessel pairs lime addition with controlled supplemental heat instead of relying on heavy lime overdosing, keeping chemical demand reasonable while reliably hitting the time, temperature, and pH thresholds required for full pathogen kill.
Enhanced Pasteurization moves the cycle into a sealed sequencing batch reactor where lime drives pH above 12 and controlled heating completes disinfection. Both pathways serve as proven wastewater pathogen reduction equipment, supported by published case studies and decades of operational data from municipalities nationwide. For Cincinnati-area facilities planning Class A capacity expansion or evaluating treatment options against Ohio EPA Region 5 oversight, these are regulator-recognized options with strong long-term track records.
Lime Slaking & Feed Systems for Cincinnati Water Treatment Facilities
Greater Cincinnati Water Works (GCWW) operates one of the largest municipal water utilities in the Midwest, anchored by the Richard Miller Treatment Plant on the Ohio River and the Bolton Treatment Plant drawing from the Great Miami Aquifer. The Miller plant is one of the largest granular activated carbon water treatment facilities in the United States, and the system serves over one million people across Hamilton County and parts of Butler, Warren, and Boone counties. Lime feed plays an important role in pH adjustment and corrosion control across the distribution network, and RDP Technologies designs lime slaking and feed systems engineered for the precision and reliability that Ohio Valley municipal operations require year-round.
The Tekkem family of lime slakers for water treatment applies load cell technology to combine a measured weight of quicklime with a measured weight of water, holding the slaking reaction within the proven 180°F to 190°F temperature window. This weight-based control approach enables precision lime dosing systems with slurry concentration adjustable from one percent up to thirty percent based on plant requirements.
The same Tekkem platform converts to operate as a hydrated lime feed system without any physical modifications, providing flexibility as lime market conditions shift across the Ohio Valley and broader Midwest. A continuous slurry delivery loop combined with pinch valve and flow meter dosing supports accurate feed at multiple application points within a facility. With only one moving part inside the reaction tank, maintenance demands stay infrequent and predictable for plants running around the clock through dramatic seasonal swings and variable Ohio River source water quality.
Custom Engineering & Process Equipment Support Serving Cincinnati
Water and wastewater infrastructure across Greater Cincinnati carries deep operational history, with facilities serving the region for more than a century in various forms and continually upgraded under one of the most active federal consent decree capital programs in the country. Plants here must handle Ohio River flood events, combined sewer system complexity, and the operational realities of serving a tri-state metro region that spans Ohio, Kentucky, and Indiana. RDP Technologies brings over 45 years of custom process equipment engineering experience to capital projects across Hamilton, Butler, Clermont, Warren, and surrounding counties on both sides of the river.
As a wastewater treatment equipment manufacturer that handles design, fabrication, and controls programming under one roof, we adapt to existing tankage, constrained urban site footprints, and operator workflows rather than forcing a generic package into a difficult location. Our intelligent control platforms integrate cleanly with SCADA systems and meet the detailed reporting expectations of Ohio EPA, Kentucky DEP for Northern Kentucky partners, and EPA Region 5 oversight.
We engage directly with municipal engineers, consulting firms, and plant operations staff from early scoping through commissioning and long-term technical support. Robust equipment, dependable process performance, and practical technologies that simply perform are the principles that have guided every project we deliver. Cincinnati-area facilities benefit from working with a single accountable manufacturer that designs, builds, and stands behind the equipment for the long haul.
Biosolids Drying Systems for Cincinnati Wastewater Plants
With multiple plants generating biosolids across the Greater Cincinnati region and ongoing consent decree capital pressure shaping long-term operating budgets, biosolids drying systems offer a strategic capital investment for cutting hauling tonnage and unlocking higher-value beneficial reuse markets across the Ohio Valley. The RDP-Fenton wastewater sludge dryer operates on a repeating batch cycle that allows drying time to be adjusted to match the natural variation in sludge cake solids concentration coming off the dewatering line.
Batch sludge drying equipment handles those upstream variations cleanly, whereas continuous-flow dryers often struggle when feed quality shifts unexpectedly. Operators in the field have repeatedly noted how little daily attention the system requires once a stable recipe is dialed in.
The dried product comes out significantly reduced in volume and weight, lowering trucking costs and opening pathways into fertilizer, soil amendment, and energy recovery markets across Ohio, Kentucky, Indiana, and the broader Midwest. Pairing the dryer with upstream RDP lime feed or storage equipment gives Cincinnati wastewater plants a fully integrated biosolids handling line backed by a single manufacturer with consistent controls and ongoing support. Long service life and ease of operation were the design priorities from the start, and that focus shows up clearly in real-world performance data from installed sites across the country.
