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 well into the next decade. Bob H from Victoria, BC Canada ran his idea for a marine pump out station past our marine pump systems engineers, see below:
“We are currently in the preliminary planning and investigation stage to determine the viability, best configuration, and cost of installing a pump-out system at our Yacht Club. The current option being considered is to install a duplex pump-out station at the outside float, approximately 600 ft. from shore. I assume that the station would be capable of sucking out the raw sewage from a holding tank and transfer it to the fixed gravity sewer on shore via a 2” force main. Any assistance with this pump out planning effort would be appreciated. I am scheduled to present a concept (or options) later this month to our planning committee. The process will likely include a complete review of options, recommendation to the board, followed by budget approval and implementation.” Thanks – Bob H.
Bob, your marine pump out dilemma seems to focus on remotely pumping out boats rather than have the pump station fixed permanently to a dock. There are lots of reasons to do this but the most common being convenient bilge pumping for boaters and handling the overflow of customers during the busy season. Wastecorp designs double pump out Mud Sucker diaphragm pumps for this purpose. Generally, the Mud Sucker 3FA-ECDD is a pump out capable of transferring up to 160 GPM. What we would suggest is using a single suction and single discharge option if you are only using the pump out to empty a holding tank.
Now, the only item of concern is the horizontal discharge of 600 ft. to the gravity sewer. You may need to move your float closer to shore (say 400-500 ft. if possible) to optimize the marine pump out. If this is not an option, you can go with a pump out boat but these tend to cost from $30,000-$75,000 depending on the size and style. The double pump out you are talking about is in the $6,000-$8000 range. You can check out these marine pump options here. Bob, you are on the right track in planning your marine pump out station and we hope this helps. Keep in mind, the Canadian provinces may have a grant program under environmental legislation similar to the way US States have the Clean Vessel Act which provides grant to marinas installing new pump out equipment.
