For over 45 years, RDP Technologies has built process equipment that performs dependably in the field, grounded in a practical engineering approach proven across hundreds of municipal installations. Utilities across Central Kentucky and the Bluegrass region rely on RDP for accurate, durable systems that stay easy to operate and simple to maintain over a long service life.
Lime Slaking & Feed Systems for Lexington Water Treatment Facilities
Kentucky American Water supplies drinking water to Lexington, drawing primarily from the Kentucky River and treating it at the Kentucky River Station plants, with additional capacity at the Richmond Road Station drawing on Jacobson Reservoir. The Inner Bluegrass sits on karst limestone geology that gives the region naturally hard water, which makes lime softening, pH adjustment, and corrosion control central to producing stable finished water. That same karst landscape, with its sinkholes and springs, adds source water protection challenges that keep treatment reliability at a premium. Dependable lime feed underpins the softening and pH chemistry, and RDP designs lime slaking and feed systems engineered to deliver it consistently at high-volume Bluegrass operations.
Tekkem slakers rely on 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 window. That weight-based control enables precision dosing with slurry concentration adjustable from one percent up to thirty percent based on plant requirements.
The same Tekkem platform converts to a hydrated lime feed system without any physical modifications, providing flexibility as lime market conditions shift across Kentucky and the surrounding region. A continuous slurry 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.

Biosolids Storage & Precision Truck Loading Systems
The Lexington-Fayette Urban County Government operates the Town Branch and West Hickman Water Quality Treatment Plants, its two major wastewater facilities, both of which have seen significant investment under the federal consent decree program addressing sanitary sewer overflows across the community. Treatment across those plants produces steady daily biosolids, and the surrounding Bluegrass farmland offers practical land application outlets. Reliable storage and loadout equipment keeps trucks moving to those fields on schedule through the region's humid summers and occasional winter ice. RDP Technologies engineers biosolids storage systems and precision truck loading systems that automate the full run, from the dewatering line to the fully loaded truck pulling out.
Moving floor technology inside live bottom bin storage keeps heavy sludge cake advancing steadily, heading off the bridging and rat-holing that stall conventional steep-walled hoppers. Loadout runs automatically through the precision truck loading system, closing most loads within minutes and holding within a couple hundred pounds of the operator's target weight.
Three decades and roughly three hundred biosolids conveying installations have refined a bay layout that keeps trucks clean, departures on schedule, and operator attention at the bay minimal. With loading running on its own, Lexington-area staff can redirect their hours to higher-value work across the plant. For a program hauling to Bluegrass land application sites through the full range of Kentucky seasons, that automation lifts throughput and holds overtime down.

Custom Engineering & Process Equipment Support Serving Lexington
Water and wastewater infrastructure across the Lexington region works within a distinctive Bluegrass setting, where karst limestone geology, sinkhole-prone terrain, and a long-running federal consent decree to curb sanitary sewer overflows all shape how facilities are planned and built. Plants here also contend with humid summers, periodic flooding, and winter ice events. RDP Technologies brings over 45 years of custom process equipment engineering to capital projects across Fayette, Jessamine, Scott, and neighboring Central Kentucky counties.
Because design, fabrication, and controls programming stay under one roof, we tailor equipment to existing tankage, site constraints, and the workflows operators already rely on, rather than forcing a stock package into a poor fit. Our control platforms integrate cleanly with SCADA and meet the detailed reporting the Kentucky Division of Water and EPA Region 4 require.
We work directly with municipal engineers, consulting firms, and plant operations staff from the earliest scoping through commissioning and long-term technical support. Durable equipment, dependable process performance, and practical technology that keeps performing are the principles behind every project we deliver. Lexington-area facilities gain a single accountable manufacturer that designs, builds, and stands behind its equipment for the long haul.

Biosolids Drying Systems for Lexington Wastewater Plants
As capital budgets across Central Kentucky stay focused on consent decree obligations and long-term operating efficiency, and hauling costs remain a factor, reducing biosolids weight is one of the most effective steps a Lexington-area plant can take. Drying offers a direct path to lower tonnage and higher-value end products. The RDP-Fenton sludge dryer runs on a repeating batch cycle, letting drying time follow the natural variation in cake dryness coming off dewatering rather than a fixed rate.
Batch sludge drying equipment absorbs those upstream shifts cleanly, where continuous-flow dryers often struggle when feed quality changes without warning. Operators in the field regularly note how little daily attention the system needs once a stable recipe is dialed in.
The dried product emerges markedly reduced in volume and weight, cutting trucking costs and opening pathways into fertilizer, soil amendment, and energy recovery markets across Kentucky and the surrounding region. Paired with upstream RDP lime feed or storage equipment, a Lexington plant gains a fully integrated biosolids line backed by one manufacturer with consistent controls and ongoing support. Long service life and simple operation guided the design from the start, and installed sites bear that out in real performance data.

Biosolids Lime Stabilization & Pasteurization Solutions in Lexington, KY
Kentucky manages biosolids under the Kentucky Division of Water, and while the Bluegrass region's farmland has long supported Class B land application, growing attention to PFAS and emerging contaminants is drawing more utilities toward Class A material and the flexibility it brings. RDP Technologies has delivered EPA 503 compliant lime-based solutions since those federal rules were first established, supporting both Class A biosolids treatment and Class B biosolids stabilization at facilities across Kentucky and the surrounding states.
EnVessel Pasteurization is one of the most widely deployed Class A processes in the country, with more than 70 installations in operation. It pairs lime addition with controlled supplemental heat rather than relying on heavy lime overdosing, keeping chemical demand reasonable while reliably meeting 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 pathogen reduction equipment, supported by published case studies and decades of municipal operating data. For Lexington-area facilities planning capital upgrades against Kentucky Division of Water requirements and evolving reuse expectations, these are regulator-recognized options with strong long-term track records.
