Custom-Made Pump Kleen®
Pumpout Boats & Floating Restrooms
Warwick, Rhode Island
The following specification describes a floating restroom or otherwise called a floating sanitation facility, for use in no discharge waters. The floating restroom is designed for ease of use, long-term durability and low maintenance. Integrity of the holding tank is a primary goal, even under abusive conditions, such as grounding and other impact.
In general, the floating restroom is constructed of composite materials, in accordance with standard marine industry practices. Hardware components suitable for a marine environment are fitted for functionality and use.
The floating restroom is designed to have one fully compliant unisex restroom meeting ADA Accessibility Guidelines (see below). This includes the fixtures, all internal spaces, external walkways and approaches, railings, door openings, etc. A second, non-ADA restroom is provided. Lastly, a utility/storage unit is included.
Composite Materials-General - Floating Restroom
Exterior Gelcoat: ISO NPG sprayed at 21mils (wet)
Interior Gelcoat: ISO NPG sprayed at 21mils (wet)
Resin: General purpose DCPD polyester
Reinforcement: Standard “E” glass cloth, mat, gun roving and woven roving
Foam Core: Divinycell closed cell or equivalent
Hull - Floating Restroom
The hull is constructed as a single unit. The design incorporates a center hull and outer floats. The outer floats are compartmented from the center hull. The initial layer of reinforcement will be laminated with vinyl-ester resin for improved blister resistance. The laminate shall be comprised of gun roving, foam and woven roving. The nominal bottom external skin thickness is 0.26”. The hull is mechanically secured and sealed to the main deck after complete lamination of the holding tank and other structures. The center hull and outer floats are also fitted with internal structure and baffles appropriate to the requirements.
Holding Tank - Floating Restroom
The tank is constructed separately from the external tank shell. The laminate is comprised of gun roving and woven roving, to a nominal thickness of 0.14”. The tank top will be laminated of gun roving, foam core and woven roving. Nominal thickness is 0.85”. There will be 6 internal, foam cored transverse baffles, laminated in place. A minimum of 2 clean out plates and one inspection hatch will be fitted to the top. The top will be bonded into the external shell. The tank will have a 2” PVC pipe at the center of the holding tank. This will be used for tank pump-out. The cavity between the tank and the outer shell will be 2” PCF foam. The tank capacity is 1000 gallons.
Deck - Floating Restroom
The floating restroom deck has a non-skid gelcoat surface and is laminated from gun roving, foam core and woven roving. Nominal thickness will be 1.21”. The deck will have a downward turning perimeter flange of sufficient width for fitting a rub rail and corner bumpers. Extra laminate is provided in the flange for durability. The deck will be secured to the hull with a “shoe box” style joint, covered with a heavy-duty rub rail.
House - Floating Restroom
The floating restroom house is designed with three compartments. The large compartment is an ADA compliant unisex restroom (see compliance section), and houses the restroom fixtures. The second compartment is the utility room and houses electrical components, pump-out connections, provides supply storage, etc. This space is not ADA compliant. The third compartment is a non-ADA restroom, and houses the restroom fixtures. Space is allowed for a shower stall (optional). The house is laminated with gelcoat inside and out, gun roving and foam core. The nominal thickness is 0.68”. FRP, gel coated, self-closing doors are fitted at to each compartment. Doors have standard locks, and louvered vents. The restroom doors are a minimum width of 34”.
Roof - Floating Restroom
The floating restroom roof is laminated with gelcoat, gun roving, foam core and woven roving to a thickness of approximately 0.68””. The roof provides overhangs on the ends for some protection from the elements. The roof is peaked with a slope in accordance with standard building criteria for snow load.
Fresh Water System - Floating Restroom
The restroom compartments contain a toilet and sink. A pressure water pump and expansion tank will be provided in the utility room. City or marina water connection will be provided in the utility room. All piping will be fitted with heater tape to prevent freezing.
Black Water System - Floating Restroom
The toilet and sink discharge directly into the holding tank, which is vented to the roof. The floor drains directly into the holding tank.
Electrical System - Floating Restroom
A 30-amp 110/120VAC electrical system will be provided, including a connection (in the utility room) to the marina shore power. Interior lighting to be appropriate to facility use. Exterior courtesy lighting for walkway illumination to be provided. Doorway lights at each door.
Float Ballasting System - Floating Restroom
A system will be provided to ballast the hull wing sections with water, in four separate compartments. The purpose of the ballasting system is two fold. The unit is designed with 20” of freeboard in the light ship condition. The ballast system will allow the unit to be “sunk” to existing floating dock freeboards of 17” to 20”. The second purpose is to allow the unit to be “trimmed” both longitudinally and transversely to accommodate non-symmetrical weight distribution. The Float Ballast System (FBS) is trademarked and patent pending.
Access & Railings - Floating Restroom
The facility is designed with shore access from the “long” side of the deck. The unit will have water access on the opposite side via an 20’ nominal opening between the railings The perimeter railings are designed with a bottom rail, flush to the deck, which provides the required retainer lip for ADA compliance. Additionally, there is a hand rail all around the house.
Signage - Floating Restroom
Signage appropriate to a marine environment will be provided as necessary
