Water & Wastewater Treatment Equipment Serving Indianapolis, IN
Precision lime feed, biosolids stabilization, drying, storage, and truck loading systems engineered by RDP Technologies for Indianapolis-area municipal facilities.
Trusted Process Equipment for Indianapolis 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. Indianapolis-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.
Biosolids Drying Systems for Indianapolis Wastewater Plants
Hauling logistics and disposal costs across central Indiana make biosolids drying systems a strategic investment for wastewater plants looking to reduce long-term operating expenses. The RDP-Fenton wastewater sludge dryer runs on a repeating batch cycle that allows drying time to be adjusted to match natural variation in sludge cake solids concentration coming off the dewatering line.
Batch sludge drying equipment handles those swings cleanly, whereas continuous-flow dryers often struggle when upstream output 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, cutting trucking costs and opening pathways into fertilizer, soil amendment, and energy recovery markets across Indiana and the broader Midwest. Pairing the dryer with upstream RDP lime feed or storage equipment gives Indianapolis 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 guided the original design, and that focus shows up clearly in real-world performance data from installed sites across the country.
Custom Engineering & Process Equipment Support Serving Indianapolis
Water and wastewater infrastructure throughout the Indianapolis region has been built and rebuilt across multiple regulatory eras, with treatment assets often expanded to keep up with steady growth in central Indiana. RDP Technologies brings over 45 years of custom process equipment engineering experience to projects across Marion County and surrounding service areas.
As a wastewater treatment equipment manufacturer that handles design, fabrication, and controls programming under one roof, we adapt to existing tankage, demanding site footprints, and established operator workflows rather than forcing a generic package into a difficult location. Our intelligent control platforms integrate with SCADA systems and meet the detailed reporting expectations of Indiana IDEM 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. Indianapolis-area facilities benefit from working with a single accountable manufacturer that designs, builds, and stands behind the equipment for the long haul.
Biosolids Lime Stabilization & Pasteurization Solutions in Indianapolis, IN
Biosolids handling for utilities in and around Indianapolis, IN carries decades of regulatory history, and RDP Technologies has been delivering compliant lime-based solutions in this space since the EPA 503 rules were first written. Our biosolids lime stabilization product line supports both Class A biosolids treatment and Class B biosolids stabilization, giving central Indiana utilities real flexibility based on disposal pathways and beneficial reuse goals.
The EnVessel Pasteurization biosolids pasteurization system remains one of the most widely deployed Class A processes in the country, with more than 70 installations operating across the United States. EnVessel pairs lime with supplemental heat instead of leaning 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 the disinfection step. Both options serve as proven wastewater pathogen reduction equipment, supported by published case studies and operational data from municipalities nationwide. For Indianapolis-area facilities planning capital upgrades or evaluating new approaches, these are regulator-recognized pathways with strong track records.
Lime Slaking & Feed Systems for Indianapolis Water Treatment Facilities
Indianapolis water treatment plants draw from the White River along with regional reservoirs at Eagle Creek and Geist, all of which require consistent pH adjustment and softening before water reaches the distribution network. RDP Technologies designs lime slaking systems and lime feed systems engineered for the precision and reliability that high-volume Indiana municipal operations require.
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 180°F to 190°F window where the chemistry performs at its peak. This weight-based control approach is what enables precision lime dosing systems with slurry concentration adjustable from one percent up to thirty percent based on plant requirements.
The same Tekkem platform can run as a hydrated lime feed system without any physical modifications, giving Indianapolis operators flexibility as lime market conditions shift across the 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 in support of central Indiana’s service population.
Biosolids Storage & Precision Truck Loading Systems
Treatment plants serving the Indianapolis region handle significant daily biosolids volumes, and dependable material handling at the loadout bay is essential to keeping the broader hauling program on schedule through Indiana’s full range of weather conditions. RDP Technologies engineers biosolids storage systems and precision truck loading systems that automate the full flow from dewatering equipment through to the departing truck.
Moving floor technology built into live bottom bin storage keeps sticky sludge cake moving consistently even in cold Midwest winters, 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 loads typically completed within minutes and held to within a couple hundred pounds of the operator’s target weight.
Three decades and roughly 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 constant attendance, Indianapolis plant staff can redirect labor toward higher-value tasks elsewhere in the facility. For utilities managing demanding weekday hauler rotations, that automation translates directly into reduced overtime and smoother daily operations.
