RDS-20 Rainwater Management System (Rain Diverter)

Rain Diverter System Panel Control

Many wash facilities do not have a roof over the wash pads so when it rains, storm water can flow through the pre-treatment system into the city sewers and overwhelm the system. To make sure that doesn’t happen, we have designed a simple, programmable rain diverter system (RDS-20).

The concept is fairly straightforward. When the system senses at least ¼” of rainfall, a controller turns on the pumps for a pre-set time to remove the floating oils and water from the wash pad through our pre-treatment system. This time is factory set for 15 minutes, but can be readily changed to suit field conditions.

After the first flush of rainwater with the contaminants are removed, the RDS then shuts down the system to prevent excess storm water from entering the tank and the sewer system.  After the rain event, the RDS will reset to allow normal operation of the treatment system.  If needed, the system can be manually overridden to allow washing operations during rain events.


  • Adjustable rain sensor
  • Actuator and Jandy Valve
  • Programmable controller with manual/automatic switch capability


  • Captures and directs first flush waters and contaminants
  • Ideal for uncovered wash bays
  • Can be designed to work with new or existing recycling systems
  • Compact design can be mounted anywhere
  • Can be configured to work with electric or air operated pumps
  • Completely field programmable for rain sensitivity, pumping duration, and reset time.

Monitoring System to find oil in water

Do you need an economical way to continuously monitor how much oil is in your water to ensure acceptable discharge levels?

Our Oil Content Analyzer with electro-optical sensing can detect even trace amounts of oil in water flowing through a pipe – and send an alarm if the amount exceeds a certain level.

Applications include:

  • Aircraft and truck washdown facilities
  • Storm water runoff
  • Ground water reclamation
  • Oil Water Separator Effluent monitoring
  • Power plant effluent
  • Industrial process water discharge
  • Fuel transfer station rain water runoff
  • Bilge water discharge monitoring

The design is very straight forward. The monitor is attached directly to the pipe carrying the oil water mixture. Every 8 seconds, a small sample is taken through the pipe wall. A light source shines through the sample and the system measures how much light has been absorbed and translates that into oil concentration. After the measurement, the sample is put back into the water stream.

This oil content value can be adjusted to any level between 2 and 500 ppm (or higher, if needed). When the measured oil concentration is higher than the pre-set value, visual and audio alarms will activate. The alarm relay output can also be used to control valves, pumps and/or an external alarm circuit. Many other options can be added including 4-20ma outputs.


  • Self-Cleaning: Optical surface is cleaned each time it samples and expels water. Reduces maintenance and eliminates errors from fouled surfaces.
  • Completely Automatic Operation: Requires no attention from operators
  • Easily Installed: Just install through piping, no troublesome tubing
  • Reliable Sampling: Provides real-time results every 8 seconds without distortion
  • Rugged Design: Marine grade 316 stainless steel, bronze and aluminum.
  • Lightweight and Compact: Weighs less than 18 lbs (8 kg)


  • S. Coast Guard 162.050/3013/1
  • ABS OONN10170, 95-NN7502-X
  • IMO Resolution MEPC.60 (33).

Debris Baskets
Stainless Steel Debris Baskets

Our Wash Bay Solutions Stainless Debris Baskets are designed to both protect the equipment and help control costs associated with solids removal from wash bay sumps. The baskets are for washing applications with an average amount of solids. The baskets fit snugly into the sump and catch all solids from the wash bay before they reach the recycle systems. When the basket is full, personnel remove it and set it to the side to dewater. A second basket can then be placed into the sump and washing can continue. Once the sediment in the first debris basket is de-watered, it can be easily disposed of according to local enforcement agency regulations.


  • Heavy Equipment Washing
  • Aircraft Maintenance
  • Truck & Bus Washing
  • Forklift Wash Facilities
  • Military Bases


  • Low Maintenance
  • Heavy Duty Construction
  • Impervious to Non-petroleum Materials
  • Easy to Install

The baskets are constructed of stainless steel plates and stainless mesh. They come in standard sizes or custom sizes to fit into an existing sump. One or two handles on each basket make them easy to move around.

Why Do I Need a Re-Cyke® TWB System?

These complete wash systems are ideal for washing equipment and vehicles at sites without incurring any construction costs, delays, or permanent structures. Used on military bases, construction sites, and at any facility requiring transportability, these cost effective systems can be configured for a wide range of applications and up and running in a few weeks. Recycling wash water also eliminates EPA and local impact fees, reduces sanitary sewer costs, and water restrictions.

How Does the Re-Cyke® TWB System Work?

The complete system consists of a self-contained aboveground wash pad and an enclosed equipment room. The pad includes a 12” high ramped structure capable of handling up to 40 tons/axle and tracked vehicles, an integrated water collection system to isolate solids and divert liquids, and a solids wash-down feature. The enclosed equipment room sits adjacent to the wash pad and contains complete water recycling, high-volume demucking, and high-pressure washing equipment.

As vehicles are cleaned on the pad, the wash/rinse water collects beneath the pad and is transferred to the closed loop recycling system for treatment and reuse so there is no off-site discharging. The solids removed from the vehicle are automatically washed to a collection section for future removal and disposal.
