Has anyone added a gray water tank on their 32xx? I need to trap the shower and sink; any advice oh mighty forum ? The sink looks reasonable, but have not even looked at the shower drain yet.

Gray water tankage is pretty uncommon on boats in North America. The challenge is that you need to have as much gray volume as you have potable water tank volume.
Where are you operating that you need to hold gray water?

Lake Pend Oreille, moored in the slip next to the Sheriff's boat. I had no idea until the Admiral was taking a shower and The Man happened to be standing dockside drinking my coffee. He warned me not to let the gray water into the lake. We are very careful about bio-products and all that. Probably be easier to change slips. Our current moorage does not offer a shower unfortunately.whiskywizard wrote:

I'd check into that. It may not include grey water as he thinks. See the blue text at the end. Not sure what the Idaho rules are?
WAC 332-52-120
Agency filings affecting this section
Sanitation.
(1) How and where can refuse or waste be disposed on department-managed lands?
(a) Where toilet or sewage facilities are provided, no person shall dispose of human waste except in those facilities.
(b) Persons shall not deposit an individual's solid human waste within two hundred feet of any campsite, trail, or body of water. An individual's solid human waste shall be disposed of by burying to a depth of at least six inches.
(c) Where the department has provided receptacles, persons shall deposit bottles, cans, waste paper, garbage and other appropriate refuse in designated receptacles. If no receptacle is provided, persons shall take such refuse with them for disposal off-site.
(d) Persons shall not use department-provided receptacles for the disposal of personal or commercial refuse, garbage, debris or waste not associated with recreational activities on department-managed lands.
(e) Persons shall not leave or burn refuse or waste of any kind on department-managed lands, nor pollute or contaminate department-managed lands, including but not limited to any stream, river, lake, marine waters, or other body of water running in, through, or adjacent to department-managed lands, except as authorized by these rules.
(f) DNR may establish controlled discharge areas in order to prohibit discharge of waste from vessels in designated water recreation facilities as referred to in WAC 332-52-305(1). Refuse or waste from vessels does not include the discharge of greywater.
(2) Any violation of this section is an infraction under chapter 7.84 RCW.

The above is the enviornmental plan for that lake with specifics on overboard discharge. So how do you get rid of grey water, pump it out at sewer pump out I guess.

Wow... that doesn't even seem realistic. I suppose a gravity drain into a bilge holding tank would be the easiest. You could tee that into your main holding tank and transfer it over for pumpout I suppose.

I am certain when the environmental impact statement was developed the impact to boaters and the resultant costs were taken into account.SomeSailor wrote:

Why not just pipe the shower and sink drains into the blackwater tank. Then when you get vac'ed out, it's all gone. You may want to increase the size of the blackwater tank though, or get vac'ed more often.

I looked into this when we were in Lake Superior since most of the states surrounding it have a similar law. The shower is actually the easiest on my 3270 since it "pumps" out (and up) anyway and can pump into a tank above or below the water level. Sinks are a different matter, my original plan was to only catch the galley and head sinks and leave the other two alone, since sinks are gravity drained you either have to install a tank below them with no high points in the drain hose or a pump. Additionally in a house you have a"P" trap to keep odors contained and discharge from the galley sink may have more food solids to deal with too. So a grey tank will collect debris just like a black water tank. RV's have grey water tanks but they are usually mounted under the RV and can gravity feed and they drain them similarly to the black water. I ended up not doing anything other than avoiding obvious discharge in the marina. Then we moved and it hasn't been an issue.

Sounds like a good plan.
