Water & Wastewater Treatment Equipment Serving Riverside, CA
Precision lime slaking, biosolids stabilization, drying, storage, and truck loading systems engineered by RDP Technologies for Riverside and Inland Empire municipal facilities.
Trusted Process Equipment for Riverside 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. Riverside-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.
Biosolids Storage & Precision Truck Loading Systems
Inland Empire wastewater agencies handling biosolids from rapidly growing populations across Riverside and San Bernardino counties depend on storage and loadout equipment that performs reliably day after day, often under significant daily volume swings. RDP Technologies engineers biosolids storage systems and precision truck loading systems that automate the full flow from dewatering output to departing trucks without requiring constant operator attention at the loadout bay.
Moving floor technology built into live bottom bin storage keeps sticky sludge cake flowing reliably, 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 finishing 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 labor demands minimal at the bay. Because the cycle runs without continuous attendance, Riverside-area plant staff can redirect time toward higher-value tasks elsewhere in the facility. For utilities running heavy weekday hauler rotations and managing long-distance trips to Class B-permitted land application sites, that automation directly improves daily throughput and cost predictability.
Biosolids Lime Stabilization & Pasteurization Solutions in Riverside, CA
California’s biosolids landscape has shifted significantly over the past two decades, with several Southern California counties restricting or banning Class B land application within their borders and forcing Inland Empire utilities to either truck material long distances or upgrade to Class A treatment. 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 across California facilities.
The EnVessel Pasteurization biosolids pasteurization system is 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 addition with controlled supplemental heat rather than relying on heavy lime overdosing, keeping chemical demand reasonable while hitting the time, temperature, and pH thresholds required for complete 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 Riverside-area facilities evaluating capital upgrades against California’s evolving biosolids regulations and county-level restrictions, these are regulator-recognized options with strong long-term track records.
Lime Slaking & Feed Systems for Riverside Water Treatment Facilities
Riverside Public Utilities operates one of California’s largest municipally owned utilities, drawing groundwater from the Bunker Hill and Riverside-Arlington Basins and managing a treatment portfolio that includes nitrate removal, manganese treatment, and corrosion control. Lime feed plays a meaningful role in pH adjustment and stability across the distribution network, and RDP Technologies designs lime slaking and feed systems engineered for the precision and reliability that Inland Empire 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 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 Southern California. 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 the Inland Empire’s demanding summer peak season.
Custom Engineering & Process Equipment Support Serving Riverside
Water and wastewater infrastructure across the Inland Empire has been built and expanded across decades of population growth, with treatment facilities designed to handle the operational demands of one of California’s most rapidly developing regions. RDP Technologies brings over 45 years of custom process equipment engineering experience to projects across Riverside, San Bernardino, and the surrounding counties.
As a wastewater treatment equipment manufacturer that handles design, fabrication, and controls programming under one roof, we adapt to existing tankage, tight site footprints, and established 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 California State Water Resources Control Board, regional Water Boards, and EPA Region 9 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. Riverside-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 Riverside Wastewater Plants
The long-distance hauling routes that Inland Empire wastewater utilities have historically used for biosolids disposal across Kern County and the Central Valley make drying systems an especially strong capital investment for Riverside-area plants. 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 swings 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 substantially reduced in volume and weight, lowering trucking costs and opening pathways into fertilizer, soil amendment, and energy recovery markets across California and the broader Southwest. Pairing the dryer with upstream RDP lime feed or storage equipment gives Riverside 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.
