Water & Wastewater Treatment Equipment Serving Richmond, VA
Precision lime slaking, biosolids stabilization, drying, storage, and truck loading systems engineered by RDP Technologies for Richmond and Central Virginia municipal facilities.
Trusted Process Equipment for Richmond 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. Richmond-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.
Biosolids Storage & Precision Truck Loading Systems
The City of Richmond Department of Public Utilities operates the Richmond Wastewater Treatment Plant, while Henrico County and Chesterfield County operate substantial regional facilities including the Henrico County Water Reclamation Facility and the Falling Creek and Proctors Creek wastewater plants. Together these utilities manage daily biosolids volumes serving more than one million residents across the Richmond metro region, with material moving to land application sites across the Piedmont and Tidewater regions of Virginia. Reliable storage and loadout equipment is essential to keeping that program running through humid summers and the heavy nutrient compliance scrutiny of Chesapeake Bay watershed operations. 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 through Mid-Atlantic seasonal swings, 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, Richmond-area plant staff can redirect labor toward higher-value work elsewhere in the facility. For utilities managing weekday hauler rotations to Piedmont and Coastal Plain agricultural land application sites, that automation directly improves daily throughput and reduces overtime costs.
Biosolids Lime Stabilization & Pasteurization Solutions in Richmond, VA
Virginia operates one of the more detailed biosolids regulatory programs in the country under Virginia Department of Environmental Quality (VDEQ), with state-level permits required for land application alongside federal EPA 503 standards. The Chesapeake Bay TMDL adds significant capital planning pressure across Central Virginia, with sustained focus on reducing nutrient loadings reaching the Bay. Class A pathways continue to attract Richmond-area utilities seeking broader reuse flexibility. 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 Chesapeake watershed.
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 Richmond-area facilities planning capital upgrades against VDEQ requirements and Chesapeake Bay restoration targets, these are regulator-recognized options with strong long-term track records.
Lime Slaking & Feed Systems for Richmond Water Treatment Facilities
The City of Richmond Department of Public Utilities operates the Richmond Water Treatment Plant on the James River, supplying drinking water to the city and providing wholesale service to neighboring utilities. Henrico County, Chesterfield County, and Hanover County operate additional surface water treatment facilities drawing from the James and supplementing with local sources. James River source water carries seasonal variation in turbidity and natural organics, and lime feed plays an important role in pH adjustment, corrosion control, and Lead and Copper Rule compliance. RDP Technologies designs lime slaking and feed systems engineered for the precision and reliability that Mid-Atlantic 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 Virginia and the broader Mid-Atlantic. 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 Richmond’s variable seasonal demand cycle.
Custom Engineering & Process Equipment Support Serving Richmond
Water and wastewater infrastructure across the Richmond metro region carries deep operational history, with facilities serving the area for more than a century and continually upgraded to meet evolving Chesapeake Bay restoration and James River water quality commitments. Plants here must handle hurricane events, James River flood conditions, and the operational complexities of serving Virginia’s capital region and its growing suburban counties. RDP Technologies brings over 45 years of custom process equipment engineering experience to capital projects across Richmond City, Henrico, Chesterfield, Hanover, and surrounding counties.
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 Virginia Department of Environmental Quality, Chesapeake Bay Program coordination, and EPA Region 3 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. Richmond-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 Richmond Wastewater Plants
With Chesapeake Bay TMDL pressure tightening biosolids program oversight across Virginia and beneficial reuse market dynamics shifting, biosolids drying systems offer Richmond-area wastewater plants a strategic capital investment for reducing hauling tonnage and unlocking higher-value end products. 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 Virginia, Maryland, North Carolina, and the broader Mid-Atlantic. Pairing the dryer with upstream RDP lime feed or storage equipment gives Richmond 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.
