Water & Wastewater Treatment Equipment Serving Sacramento, CA
Precision lime slaking, biosolids stabilization, drying, storage, and truck loading systems engineered by RDP Technologies for Sacramento and Central Valley municipal facilities.
Trusted Process Equipment for Sacramento 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. Sacramento-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.
Biosolids Storage & Precision Truck Loading Systems
Sacramento Regional County Sanitation District (Regional San) operates the EchoWater Resource Recovery Facility in Elk Grove, one of the largest wastewater treatment plants on the West Coast, serving roughly 1.6 million people across the greater Sacramento metro region. Substantial daily biosolids volumes move through Regional San’s long-running beneficial reuse program to agricultural land application sites across the Central Valley and Sacramento Valley. Dependable storage and loadout equipment is essential to keeping that program running smoothly across the area’s intense summer heat and winter Tule fog conditions. 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 prolonged 100-plus-degree summer stretches and through cool, damp winter mornings, 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, Sacramento-area plant staff can redirect labor toward higher-value work elsewhere in the facility. For utilities running heavy weekday hauler rotations to Central Valley agricultural land application sites, that automation directly improves daily throughput and reduces overtime costs.
Biosolids Lime Stabilization & Pasteurization Solutions in Sacramento, CA
California’s evolving biosolids regulatory landscape, combined with restrictions in some Southern California counties pushing more material toward Central Valley land application sites, has made Sacramento-area biosolids strategy a focal point for utilities across Northern California. Capital planning increasingly emphasizes Class A pathways for broader market flexibility and regulatory certainty. 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 state.
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 Sacramento-area facilities planning capital upgrades against California State Water Resources Control Board oversight and the evolving statewide biosolids and PFAS regulatory environment, these are regulator-recognized options with strong long-term track records.
Lime Slaking & Feed Systems for Sacramento Water Treatment Facilities
The City of Sacramento operates the Sacramento River Water Treatment Plant and the E.A. Fairbairn Water Treatment Plant, drawing primarily from the Sacramento and American Rivers to serve hundreds of thousands of residents across the metro core. Surrounding jurisdictions in Placer, El Dorado, and Yolo counties operate additional facilities drawing from a mix of surface water and groundwater sources. Lime feed plays an important role in pH adjustment, corrosion control, and Lead and Copper Rule compliance, and RDP Technologies designs lime slaking and feed systems engineered for the precision and reliability that Northern California 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 Northern 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 Sacramento’s dramatic summer demand peak season.
Custom Engineering & Process Equipment Support Serving Sacramento
Water and wastewater infrastructure across the Sacramento region balances state capital growth, agricultural and environmental water demands, and the operational complexities of serving a metro area that straddles the Sacramento-San Joaquin Delta. Plants here must operate through dramatic seasonal swings, atmospheric river flood events, and the regulatory demands that come with being in California’s political capital. RDP Technologies brings over 45 years of custom process equipment engineering experience to capital projects across Sacramento, Placer, El Dorado, and Yolo counties.
As a wastewater treatment equipment manufacturer that handles design, fabrication, and controls programming under one roof, we adapt to existing tankage, constrained 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 California State Water Resources Control Board, Central Valley Regional Water Quality Control Board, 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. Sacramento-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 Sacramento Wastewater Plants
As California biosolids regulations continue to evolve and beneficial reuse market access becomes increasingly competitive, biosolids drying systems offer Sacramento-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 California and the broader West. Pairing the dryer with upstream RDP lime feed or storage equipment gives Sacramento 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.
