The Modern Sewer Solution
Prelos is the answer for community sewer, offering low life-cycle and initial capital costs and enabling more cost-effective wastewater treatment. This technology is based on nearly four decades of proven sewer solutions.

AdvanTex® AX-Greywater is the solution.

Wastewater Treatment & Reuse

Water reuse is no longer a choice. It’s a necessity. As supplies of fresh water become increasingly scarce, methods of recycling and reusing this vital resource are getting more attention than ever before. Orenco’s AdvanTex® Treatment Systems consistently produce clear effluent that meets the most stringent permit limits. This effluent is suitable for a variety of reuse applications (governed by local regulations) including irrigation, toilet flushing, industrial cooling, and car washing. With a 15-year track record, the AdvanTex textile filters are a proven technology that not only treats greywater to reuse levels, but is also ideal for treating residential or commercial wastewater.

Wastewater treatment systems designed for reuse applications need to meet permit limits specific to their particular city, county, or state. Orenco’s AdvanTex® Treatment Systems use a multi-pass, packed-bed filter technology that’s ideal for handling highly variable flows and is also inherently more stable than suspended-growth, activated-sludge systems. A more stable process means greater reliability, lower operation and maintenance requirements, and greater confidence in meeting permit limits.

Countless waterfront homes treat their wastewater with AdvanTex® Systems.

Cost-Effective, Environmentally Sound

Orenco Sewer™ (effluent-only sewer) is a cost-effective, environmentally sound wastewater collection system. With an Orenco Sewer, raw sewage flows from a house or business to a watertight underground tank. Only the filtered liquid portion is discharged (by either pump or gravity) to shallow, small-diameter collection lines that follow the contour of the land. Solids remain in the underground tank for passive, natural treatment and only need to be pumped every 10 to 12 years (depending on the number of residents and the tank volume).

Orenco Sewers take significantly less time to install than conventional sewers. And in an Orenco Sewer, material and excavation costs are reduced because the inexpensive collection lines are shallowly buried just below the frost line. Because only liquid is being pumped, system designers don’t need to worry about minimum velocities and associated grades. This simpler installation process causes less disruption to communities and allows businesses to operate normally during construction.

Proven, Dependable, Scalable

Orenco’s AdvanTex® AX-Max™ Treatment Systems are a dependable, proven technology for treating domestic-strength, primary-treated effluent to better-than-secondary standards, including nitrogen-reduction. They consist of sturdy, watertight fiberglass tanks that incorporate recirculation-blend and discharge tankage in a single module. Each unit also includes pumping systems, ventilation, and a lightweight, highly absorbent, engineered textile media that treats a tremendous amount of wastewater in a small space.

Applications

AX-Max Treatment Systems are intended for large residential applications or for commercial and municipal applications that require advanced secondary treatment. They eliminate the need for separate recirculation and discharge tanks by performing both functions within a single module. AX-Max units are ideal for subdivisions, “fringe” development, hotels, resorts, schools, churches, businesses, manufactured home parks, RV parks, campgrounds, rest areas, and truck stops.

Flows

Depending on model, a single AdvanTex AX-Max unit can treat flows of 5000-15,000 gpd (18.9-56.8 m3/day). AdvanTex Treatment Systems are modular, however, and can be installed in multi-unit arrays to handle higher flows.

Standard, Custom, & OEM

Orenco Controls engineers control panels with extremely high standards of quality and reliability, designed specifically to minimize production costs and time. Here are some of the benefits we offer:

Customizable, Turn-Key Solutions

Orenco Composites™ manufactures buildings and shelters for many different industries, including water and wastewater, telecommunications, power utilities, and transportation. Our prefabricated buildings and shelters can be manufactured and delivered quickly as a complete, turn-key solution for your job site. That means your project can be operational in just hours after setting the prefab building in place — hours, not weeks!

DuraFiber™  FRP buildings are corrosion-resistant, UV-resistant, and impact-resistant. Orenco Composites buildings and shelters will never rot because no wood is used in the construction of our buildings or doors. All of our buildings are closed-molded with high-strength fiberglass fabrics, not the manually chopped glass that most fiberglass building manufacturers use. In addition, DuraFiber buildings and shelters are molded as a single-piece, resulting in a seamless, leak-proof structure. Our standard, 3-inch (76 mm) foam-core fiberglass walls and roof provide unsurpassed structural integrity, while keeping the interior warm with R-18 insulation. The exterior surface is protected with a high-performance polyaspartic urethane paint, far superior to standard gelcoats. DuraFiber buildings and shelters are also extremely rugged — they can withstand 160+ mph winds and support a 100-lb/ft2 live load. If you want a building built to last — and one that will stand up to extreme weather conditions — choose a high-quality DuraFiber building or shelter.

T-Max Rectangular Tanks

Orenco Composites’ rectangular fiberglass-reinforced polymer (FRP) T-Max™ tanks are versatile storage vessels, useful for a variety of industries and applications. T-Max tanks are molded as a single piece using vacuum infusion, providing a high-strength, seamless vessel. The unique foam-core structural wall design provides integral insulation (R24 or more) and strong, stiff walls — strong enough that T-Max tanks can be buried or sit above ground.

T-Max tanks can be configured with multiple baffles, access covers and hatches, safety railings, and ladders. In addition, tanks can be fully outfitted with slide rail systems, pumping systems, filters, and many other custom internal components. T-Max tanks come fitted with four steel lifting lugs for ease in moving and placing tanks.

T-Max tanks are often the most cost-effective, long-term solution for many storage requirements, outperforming other materials such as steel and concrete. Orenco Composites manufactures FRP tanks of varying sizes to meet your project needs, with capacities from 300 gallons to 40,000 gallons. We can also produce rectangular tanks that can be built in place using panel construction. These are typically used on difficult sites — indoor or outdoor — where access and space are limited.

T-Max rectangular fiberglass tanks can be used in a variety of applications, including water and wastewater treatment processes, potable and non-potable water storage, sewage storage, sludge storage, chemical storage, and much more.
