For over 45 years, RDP Technologies has engineered process equipment that stands up to hard service, backed by proven field results and a grounded design approach shaped by hundreds of working installations. Utilities across the Texas Coastal Bend rely on RDP for accurate, resilient systems that stay easy to run and simple to maintain across a long service life.
Biosolids Lime Stabilization & Pasteurization Solutions in Corpus Christi, TX
Corpus Christi manages its biosolids under TCEQ oversight, and with South Texas ranch and farmland nearby, Class B land application has long been a practical outlet, though tightening scrutiny on emerging contaminants and hauling economics is pushing more utilities toward Class A material that travels to broader markets. Protecting the sensitive bay and estuary systems that ring the city adds further weight to how residuals get treated and where they go. RDP Technologies has delivered EPA 503 compliant lime-based solutions since those federal rules first took effect, supporting both Class A biosolids treatment and Class B biosolids stabilization at facilities across Texas and the Gulf Coast.
EnVessel Pasteurization is one of the most extensively deployed Class A methods in the nation, with well over 70 systems in service. It brings lime together with a metered amount of supplemental heat rather than resorting to heavy lime overdosing, which reins in chemical use while consistently satisfying the time, temperature, and pH requirements for a full pathogen kill.
Enhanced Pasteurization advances the process into a sealed sequencing batch reactor, where lime raises pH beyond 12 and controlled heat finishes the disinfection. Both pathways qualify as proven pathogen reduction equipment, documented in published case studies and long records of municipal service. For Corpus Christi-area facilities weighing capital investment against TCEQ requirements and coastal water quality goals, these are regulator-recognized options with deep, well-substantiated track records.

Lime Slaking & Feed Systems for Corpus Christi Water Treatment Facilities
Corpus Christi Water treats supplies from the Nueces River system, drawing on Lake Corpus Christi and Choke Canyon Reservoir and supplementing through the Mary Rhodes Pipeline that reaches Lake Texana and the Colorado River, with the bulk of treatment handled at the O.N. Stevens Water Treatment Plant. Persistent drought and enormous industrial demand from the port and refinery corridor have driven the city toward seawater desalination as a new pillar of supply. Balancing chemistry across those varied and often drought-stressed sources places heavy demands on pH adjustment, hardness control, and corrosion stability, all of which lean on dependable lime feed. RDP designs lime slaking and feed systems built to hold that chemistry steady across a diverse and evolving supply mix.
Tekkem slakers govern dosing by weight, using load cells to measure quicklime and water each to a set mass before they meet, holding the slaking reaction within the established 180°F to 190°F range. That weight-driven method delivers dependable dosing accuracy and lets operators tune slurry strength anywhere from one to thirty percent for the plant at hand.
The same Tekkem platform converts to hydrated lime feed service without any physical rework, a genuine convenience as lime availability and cost fluctuate across the Gulf Coast. A recirculating slurry loop paired with pinch valve and flow meter control delivers precise feed to each point a plant calls for, and with only one moving part in the reaction tank, upkeep stays sparse and predictable under continuous duty.

Custom Engineering & Process Equipment Support Serving Corpus Christi
Water and wastewater infrastructure across the Corpus Christi region has to hold up in one of the more punishing settings in the state: a Gulf Coast exposed to hurricanes and storm surge, salt air that accelerates corrosion, subtropical heat and humidity, and recurring drought, all alongside the immense water footprint of the port and its refinery and petrochemical corridor. The memory of Hurricane Harvey still shapes how the Coastal Bend approaches resilience. RDP Technologies brings over 45 years of custom process equipment engineering to capital projects across Nueces, San Patricio, Aransas, and neighboring South Texas counties.
With design, fabrication, and controls programming handled entirely in-house, we build equipment to suit the tankage already installed, the constraints of the site, and the habits of the crews who will run it, never forcing a stock unit into an ill-fitting spot. Our control systems mesh cleanly with SCADA and deliver the detailed reporting the Texas Commission on Environmental Quality and EPA Region 6 call for.
We remain in close contact with municipal engineers, consulting firms, and plant operations staff from the earliest scoping right through commissioning and years of continued support. Resilient equipment, dependable process performance, and straightforward technology that keeps on running are the commitments behind every project we deliver. Corpus Christi-area facilities gain a single accountable manufacturer that designs, builds, and stands behind its equipment for the long haul.

Biosolids Drying Systems for Corpus Christi Wastewater Plants
In a region where drought and heavy industrial demand keep water and resource efficiency front of mind, trimming the weight of biosolids leaving a plant is a cost lever worth pulling, particularly as hauling distances to viable South Texas sites lengthen. Drying gives Corpus Christi-area facilities a clear route to lower tonnage and higher-value end products. The RDP-Fenton sludge dryer works through a repeating batch cycle, which means drying time can be set to follow the shifting dryness of the cake arriving from dewatering instead of a locked-in rate.
A batch dryer manages those inlet variations with ease, while continuous units often falter when cake quality changes without warning. Crews running the system regularly remark on how seldom it needs a hands-on touch once a dependable recipe is established.
The finished product leaves the dryer far lighter and much smaller in volume, cutting trucking outlays and unlocking fertilizer, soil amendment, and energy recovery outlets across South Texas and the Gulf Coast. Placed after RDP lime feed or storage equipment, a Corpus Christi plant winds up with one continuous biosolids line under a common control scheme and a single point of support. Durability and easy operation were built into the design from day one, and the field record bears that out in measured results.

Biosolids Storage & Precision Truck Loading Systems
Corpus Christi operates a network of wastewater plants led by the Greenwood Wastewater Treatment Plant, with additional facilities including the Oso, Broadway, and Laguna Madre plants discharging to the bay and estuary systems around the city. Treatment across that network produces steady daily biosolids, and the surrounding South Texas ranch and farmland provides land application outlets, often at a real distance from the plant. Dependable storage and loadout equipment keeps trucks moving to those sites on schedule through Gulf Coast heat and humidity. RDP Technologies engineers biosolids storage systems and precision truck loading systems that automate the full run, from the dewatering line to the fully loaded truck pulling out.
Inside live bottom bin storage, moving floor technology keeps heavy sludge cake advancing without pause, so the bridging and rat-holing that seize up conventional steep-walled hoppers never get a foothold. The precision truck loading system handles loadout automatically, finishing most loads in a few minutes and holding within a couple hundred pounds of the operator's set target.
Close to three hundred biosolids conveying installations built over three decades have dialed in a bay setup that keeps trailers clean, departures punctual, and the operator's role at the bay light. Because loading proceeds on its own, Corpus Christi-area staff can turn their attention to more valuable work across the facility. For a program trucking to distant South Texas application sites through long, hot Coastal Bend summers, that automation raises throughput and keeps overtime down.
