Water & Wastewater Treatment Equipment Serving San Jose, CA
Precision lime slaking, biosolids stabilization, drying, storage, and truck loading systems engineered by RDP Technologies for San Jose and South Bay municipal facilities.
Trusted Process Equipment for San Jose 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. San Jose-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.
Biosolids Storage & Precision Truck Loading Systems
The San Jose-Santa Clara Regional Wastewater Facility serves more than 1.5 million people across San Jose, Santa Clara, Milpitas, Cupertino, Campbell, Saratoga, Los Gatos, and Monte Sereno, making it one of the largest advanced treatment facilities on the West Coast. The South Bay’s wastewater is processed to high tertiary standards before discharge to South San Francisco Bay, and daily biosolids volumes move to land application and beneficial reuse outlets across Northern California’s Central Valley and beyond. Reliable storage and loadout equipment is essential to keeping that program running smoothly across the South Bay’s mild but seasonally variable 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 throughout the year, 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, San Jose-area plant staff can redirect labor toward higher-value work elsewhere in the facility. For utilities managing long-distance hauler rotations to Central Valley land application sites and beneficial reuse markets, that automation directly improves daily throughput and reduces overtime costs.
Biosolids Lime Stabilization & Pasteurization Solutions in San Jose, CA
California’s evolving biosolids regulatory landscape, along with restrictions in some counties pushing material toward more distant land application sites, has elevated biosolids strategy across Bay Area utilities. The San Francisco Bay Regional Water Quality Control Board adds particular focus to South Bay discharges and biosolids handling. Class A treatment pathways continue to attract South Bay utilities seeking broader market access and regulatory 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 California.
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 San Jose-area facilities planning capital upgrades against California State Water Resources Control Board oversight and Bay Area regional water quality requirements, these are regulator-recognized options with strong long-term track records.
Lime Slaking & Feed Systems for San Jose Water Treatment Facilities
San Jose Water Company and the Santa Clara Valley Water District work together to supply drinking water across the South Bay, with surface water treatment at the Penitencia, Rinconada, and Santa Teresa water treatment plants drawing from a mix of local reservoirs and imported State Water Project and Central Valley Project supplies. Groundwater management adds another layer of complexity, with extensive recharge programs and conjunctive use strategies sustaining one of the most carefully managed aquifers in California. Lime feed plays an important role in pH adjustment, corrosion control, and Lead and Copper Rule compliance across these operations. RDP Technologies designs lime slaking and feed systems engineered for the precision and reliability that high-volume Bay Area 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 California’s drought response operations and seasonal demand patterns.
Custom Engineering & Process Equipment Support Serving San Jose
Water and wastewater infrastructure across the South Bay operates under the demands of supporting Silicon Valley’s economy, with treatment facilities engineered for high reliability, dense urban operating constraints, and sustained capital investment in advanced treatment and resource recovery. The San Jose-Santa Clara Regional Wastewater Facility’s major capital improvement program is one of the largest in California and reflects long-term commitments to environmental stewardship and Bay protection. RDP Technologies brings over 45 years of custom process equipment engineering experience to capital projects across Santa Clara, San Mateo, Alameda, and surrounding Bay Area 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 California State Water Resources Control Board, San Francisco Bay 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. San Jose-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 San Jose Wastewater Plants
Long-distance hauling from the Bay Area to Central Valley land application sites, combined with the South Bay’s strong focus on sustainability and resource recovery, makes biosolids drying systems a particularly attractive strategic capital investment for San Jose-area wastewater 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 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, dramatically 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 San Jose 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.
