Why Buy From Fondriest?


All system components can be purchased through Raritan or, make use of equipment that already exists on your vessel. Each complete system will consist of: a holding tank, waste transfer pump, key switch, controller and LectraSan® or Purasan™.

All waste is stored in a holding tank and the lockout switch position will determine how the waste is processed. This system eliminates the need for visits to the pump-out station in most areas.

When Hold n' Treat is set to AUTOMATIC the level of waste in the holding tank is monitored (every 30 seconds). Once the waste level reaches the HIGH LIMIT the Hold n' Treat Control Unit sends a signal activating the LectraSan® MC™ or Purasan™. The LectraSan® MC™ or Purasan™, in turn, activates a Waste Transfer Pump which moves waste (approximately 1 gallon) from the holding tank to the LectraSan® MC™ or Purasan™. This cycle is repeated approximately every seven minutes. After the fourth cycle, the system enters a cool down cycle. It will remain in the cool down cycle for approximately fifteen minutes. After cool down, the process will resume until the waste in the tank drops below LOW LIMIT.


  • All components are mounted outside of the tank
  • System can accomodate up to 2 Type I Marine Sanitation Devices for large holding tank installations
  • Waste is conveniently stored until it can be disposed of legally
  • Eliminates trips to the pump-out station
  • Lock-out switch prevents discharge of treated sewage in No Discharge Zones
  • Allows vessels to discharge their holding tank legally

First Environmental Monitoring System For Baltimore’s Inner Harbor

Baltimore’s Inner Harbor and the rivers that flow into it are important sources of water to Chesapeake Bay, popular recreation sites and the targets of an ambitious clean-up plan. But the city has for some time lacked an environmental monitoring system for tracking water quality in the harbor continuously. That is about to change, thanks to a collaboration between the U.S. Geological Survey (USGS) and Environmental Protection Agency (EPA). It will lead to the new installation of a suite of sensors that will provide the public and scientists with the first comprehensive, real time look at water quality in the harbor.

Parasite Behind Yellowstone River Fish Kill Found In Other Rivers

A parasite that caused a massive fish kill in Montana’s Yellowstone River has been found in at least seven other rivers in the state, according to the Bozeman Daily Chronicle . Scientists with the Montana Fish, Wildlife and Parks department made the find. So far, the parasite has been confirmed in the upper and lower Madison, East Gallatin, Bighorn, Stillwater, and Boulder Rivers. It had already been confirmed in the Jefferson and Shields Rivers. The microscopic parasite causes proliferative kidney disease, one of the most serious diseases to impact whitefish and trout. The effect of the disease on Yellowstone’s fish populations is exacerbated by other stressors like near-record low flows, consistent high temperatures and the disturbance caused by recreational activities.

ESPniagara Tracks Algal Toxins In Lake Erie, Protects Drinking Water

It may have taken 20 years and $20 million to develop, but Lake Erie researchers working to fight harmful algal blooms (HABs) now have a new tool to safeguard drinking water: ESPniagara. The advanced sampler has been called a “lab in a can” for its ability to sample microcystins, the most common algal toxin these days, in almost real time. The big gadget’s name is a mashup between “ESP,” for environmental sample processor, and the name of Admiral Oliver Hazard Perry’s ship during the War of 1812. “We wanted to name it something that was significant to Lake Erie,” said Tim Davis, molecular biologist and lead HABs researcher at the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Lab (NOAA GLERL) in Ann Arbor, Mich.
