Marine Pump Outs

Marine Pump Out

Managing marine sewage pump outs is one of those things that marina operators and boaters alike must deal with but was probably the last thing they thought of before opening a marina or buying a boat. That’s why companies like Wastecorp who manufacture pump out equipment work in tandem with engineers to help construct long term, reliable pump out solutions. The inquiry below is from an engineering firm who recently contacted Wastecorp for marine pump out stations for paying boaters. The firm is exploring options for designing a new pump out operation:

“Our firm is working on a marina sewage pump out project for the Port of Charleston, SC.  I am looking for information on a few of your marine pump out products to see if they will meet our needs.

We operate a saltwater marina and offer a sewage pump out service to our customers. We currently have a peristaltic pump out system but we are looking for something less complicated and more user friendly. We send the pumped out sewage through a magnetic flow meter, up to shore and to the public utility. We are billed by the utility based on our flow meter readings.

Our solution is to pump the sewage from the boats, using our existing system, to a new holding tank. From there, the sewage would be pumped quickly through the mag meter and up to the shore. We are planning two holding tanks, one 1000 gallon tank and one 500 gallon tank. The pump needs to have saltwater corrosion resistance and the ability to handle untreated sewage. We expect most boats to pump out sewage with saltwater. Additionally the pump must have a steady flow to work with our mag meter.

To meet these needs I was looking at the following products. The first is the 2″trash pump TFCC-2. It looks like it can handle untreated sewage fine. My main concern is if it would be suitable for saltwater? Does the trash pump come in stainless steel/corrosion resistant materials? From your online materials I only saw the trash pump offered in ductile iron. Fortunately we do not have difficult head or flow rate requirements. We just need the pump to not corrode quickly and not be easily clogged.

 I am also looking at the HW 525 and HW 1035 Honey Wagon skid mounted pump out stations. As mentioned above, we are planning to have two holding tanks. Would it be possible to remove the Mud Sucker® pump? We would possibly replace the Mud Sucker® pump with a trash pump. Also, the skid would be mounted to our concrete dock.

Finally I would like some information on your pump enclosures. Both the TF-6×6 and the TF-8×10 may work for use. What would be ideal would be to fit the skid mounted tanks with the pumps inside the enclosures. I was wondering if we could fit the TFCC-2 pump and HW 525 skid mounted Honey Wagon inside the TF-6×6 enclosure? Similarly, could we fit a TFCC-2 pump and HW-1035 Honey Wagon inside the TF-8×10 enclosure? Any suggestions or ideas to help meet our problems we would love to hear it.”

 There are a lot of issues that the customer raises. First,  Saltwater applications in the marine pump out industry require proper precautions to ensure that the pump and components do not prematurely wear. Wastecorp offers our Mud Sucker marine diaphragm pumps with stainless steel components for example and Viton flapper valves and diaphragms to help resist the harsh conditions of pumping, so we definitely recommend any marinas in a salt water environment go with this package which adds $600 -$800 to the cost of a package

Monetizing a marina’s pump out operation is a great idea to help control costs and keep repair parts costs down for your pump out. A mag meter is one way of doing it (measuring gallons pumped out), coin operated options and charging by vessel size are others. If you are worried about pulsation, all of our diaphragm pumps can be manufactured with pulsation dampeners or air chambers.

If a trash pump works better for the application then we can design all of our pump outs with our Trash Flow product line. Whenever possible, diaphragm pumps are recommended for their ability to pump out the wastewater and not get clogged. See our pedestal; pump outs for example that work really well for most marinas.

Enclosures are a great way to help protect your pump out investment  from the elements and during winter months. There are a variety of styles available to meet small and large marina budgets. Enclosures are a long term investment for protecting your equipment so there is an investment required.

Getting the right marine pump manufacturer to participate in your design process is critical to the overall outcome of you pump out. Contact Wastecorp  at 1-888-829-2783 to get more information for your project.

How to Plan a Marine Pump Out Station

Planning a marine pump out station is essential to getting the appropriate  pump out equipment for your marina. Consulting other marinas in your area or a marine pump manufacturer ahead of when you actually need the system installed is your best bet. Wastecorp has generally found that marinas seem to be getting larger boat and yacht traffic in the last few years that need to be pumped out. Don’t forget, since a pump out is part of your business model, you should be charging larger yachts appropriately. This trend is expected to Continue reading

What Commercial Marine Operators Should Consider Under MARPOL ANNEX 5

MARPOL ANNEX 5 Pump Systems for Commercial Vessels

MARPOL ANNEX 5 Pump Systems for Commercial Vessels

Commercial marine operators should understand that the Marpol Annex Five prohibits the disposal of cooking oil, slurries and other substances which may be considered toxic to the marine environment. All of these substances are no longer permitted to be dumped at sea no matter how far offshore. Wastecorp has worked with several companies to make this transition as painless as possible.

One of the systems we recommend to commercial vessels is the photo you see below. This is a 500 gallon (US) (1892 liter) tank engineered with a powder coated corrosion resistant frame and Mud Sucker Diaphragm pump technology. What this system does is pump almost all of the prohibited substances contained under MARPOL Annex V into a containment tank  for proper disposal once the vessel has reached shore or port. The waste in the containment tank can then be pumped into the sewer system for proper treatment at a wastewater pollution control facility.

A containment system can also help to manage multiple substances and slurries. Animal fat, wash down water, bilge water, cooking oil and other harmful substances to the aquatic environment can be transferred into the tank and out into the sewage system on land with one pump. The advantage to the user here is that you don’t have to switch pumps for transferring thicker slurries.

All commercial vessels are different. Tanker ships, passenger ships, and cargo vessels all have different needs and requirements to satisfy the new MARPOL regulations. Therefore, you should select the right size containment tank system and pump that works best for your application. You can select the containment system for your needs here. While the new MARPOL Annex 5 regulations require additional pumping equipment and extra care by your crew,  a healthier marine environment for all will emerge in the future. The key is to speak to the right company to help you get there more easily and cost effectively.

Marina Pump Outs and The New MARPOL Annex V

 

Marina Pump Outs for New MARPOL Regulations

Marina Pump Outs for New MARPOL Regulations

As many marinas know, the new MARPOL Annex 5 which prohibits disposal of garbage from ships, yachts and boats (which includes certain types of wastewater) have come into effect as of January 1, 2013. The new regulations set specific requirements for disposing of black water, cooking oil, grey water, residues, liquid detergents and animal waste. What has happened since then, is an influx of concerned pleasure boat marina operators asking what can be installed to help satisfy the MARPOL requirements and how much it will cost to implement a pump out system for yachts and super yachts? We provide some suggestions on pump outs below.

Compact Pump Out Systems

For marinas with access to a municipal sewer system line close to the facility, a compact pump out systems such as you see here can pump out yachts from 7 meters to 67 meters (25’-225’). Essentially what happens here is that pedestal pump outs are positioned in convenient areas around the marina and then simply connect to the sewer line in the boat or yacht. Most marinas select an electric driven diaphragm pump system because there is less noise and no requirement for fuel (an engine driven system is also available). Now, this pump out can be equipped with a vacuum pump system but most marinas and boaters have come to realize that vac systems are loud and bulky. Costs range from $3,500 USD -$6,000 USD.

Pump Out Septic Truck Service

In the past, many marinas along the French and Italian Riviera, Spain marinas and U.K. marinas have decided to hire a septic service to pump out waste from boats. These marinas know all too well that this is a very expensive method and is visually displeasing. But with lack of education about pump out options, many marinas have had no choice. Costs for septic truck services range from $500 USD -$2,000 USD per month depending on the amount of boat slips your marina has.

Bilge Waste Containment Systems

In North America, many marinas know these has honey wagons, but generally, these are mobile waste containment systems. What marinas can do here is either mount the containment system on the dock or inside an enclosure for aesthetic purposes. When the tank is full, the marina can discharge into the sewage system for proper treatment or take the unit on a pick up truck or cargo van to the closest approved dump station.

The MARPOL Annex V may be  a new regulation, but it does not need to be confusing. By preventing boaters from discharging into harbors and the sea, we protect and rejuvenate our marine environment. And, with the pump out technology available today it does not need to be costly for marinas to implement or difficult to install. Cost of a waste containment system range from $2,500 – $8,000 USD.
