Water & Waste

Collecting together domestic stuff I need to build a domestic water and waste system.

I am starting to get to grips with the water, waste and sanitary on board a camper van. We will have a toilet with a sink and shower but don’t for one minute imagine a spacious bathroom.

Once we get the van I will get two tank kits from CAK Tanks in Kenilworth. One will be 100ltr of fresh water and the other about the same of grey water. These underslung tanks will be wrapped in insulation to guard against freezing and will be plumbed into the kitchen and toilet / shower room. They will both have senders to the control panels so we know when they need emptying and filling.

Shurflo Pomp

Fresh water will be pumped from the tank through 15mm push fit plastic plumbing by a small 10ltr Shurflo Trailking on demand pump that actuates by the pressure drops when a tap is opened. These are nice reliable little units for motorhomes and marine use. Operating on 12V it will have a master switch on the control panel.

Binar Water Heater

Hot water will be supplied to the toilet sink and shower via a Binar 5S12 diesel water heater. This is part of a Russian made family of air and water heaters for boats and leisure vehicles. It comes as a complete kit ready to install with a small temperature controller. It will give enough hot water for a shower or wash using a few drops of fuel. They are very compact and I haven’t decided yet whether this should be underslung or whether I can find space in side.

Telford Toilet

The toilet unit will be a built in Telford 403L Cassette type system with an electric flush from the pumped water system. It has a  level indicator for the 19L cassette that can be withdrawn for emptying from the storage space behind the rear doors.




Swift Sink

The sink unit is a neat one that I found from O’Leary Motorhomes. It is actually a spare item for a Swift camper van and looks so much better than the cheap moulded sinks that are on the market. When it folds up it leaves a nice flat panel and the challenge will be to match the finish of that with the rest of the toilet / shower.

I have to find the kitchen sink.  I have seen what we want but am having trouble getting one but I will. Then we need a simple shower unit and a plug in one outside for dog washing and the like.

The grey waste will all collect from the drains into the grey water tank. This will be emptied by a simple dump valve when you are parked over the grating at a service point. It will have a flushing inlet so that it can get a quick clean out occasionally and both the tanks will have facilities for opening them up for cleaning every year,
