2. Let’s talk toilets
On behalf of “Inspiring Scotland” and “thrive outdoors”

3. • 2 stage process
• solid matter and urine separated (users must sit)
• Bulking material added to solid waste
• Hand washing by hand sanitising fluid dispenser or thermos water dispenser
(Teal)
• Unit can be built into bespoke cubicle or shed / block
PROs
• No mains water required – 4-6 litres of water “saved” with every visit
• No electricity required – naturally vented by design
• Extremely low environmental impact
• Resultant compost can be spread on land (qualify) after 2 years
CONs
• Requires user to sit and apply bulking material after bowel movement
• Requires user intervention to transfer solid waste to composting bin
• Urine needs to be collected and dealt with
• Utilising / disposing of compost - land might not be suitable for composting
(qualify)
1. Waterless – Compost toilet + compost bin

4. 1. Waterless – collection bag + compost bin
• 2 stage process
• solid matter and urine separated (users must sit)
• Hand washing by hand sanitising fluid dispenser or thermos water dispenser
(Teal)
• Unit can be built into bespoke cubicle or shed / block
PROs
• No mains water required - 4-6 litres of water “saved” with every visit
• Extremely low environmental impact
• Resultant compost can be spread on land (qualify) after 2 years
• Looks like a “normal” loo
CONs
• Requires user to sit
• Requires user intervention to transfer solid waste to composting bin (bag
collection)
• Urine needs to be collected and dealt with
• Requires mains electricity (or battery + solar panel) for venting

5. 2. Chemiloo
• Standard hire item across UK. Can also be owned outright.
• Elsan-Blu mixed with recirculating water and water stored for handwashing
• Requires no mains connection. Requires regular servicing.
PROs
• No mains water required – operates on recirculating flush system
• Fresh water in sink or hand sanitiser dispenser for hand washing
• Can be positioned anywhere
• No mains power required (unless hot wash water and/or lighting needed)
CONs
• Service company will require access to within ca. 50 feet / ca once per week
• There will be a service charge for every visit = ongoing cost
• Chemicals (25-50ml per week) within toilet have to be taken away by service
agent

6. 3. Flushing toilet & waste capture where no mains water and/or sewer is available
• Build your own toilet block with standard flushing toilets
• Water could be mains or tanker supply (under gravity – from IBC / water container)
• Collect waste underneath or next to toilet block
• No expensive groundworks required for underground pipes / septic tank / treatment
plant
PROs
• Low environmental impact
• Minimal planning issues – relocatable and removable item
• Can be used where underground tanks are not an option (tree roots, SSSI, high
water table etc.)
CONs
• Service tanker needs to gain access within 50 feet of tank for cleaning
• Regular emptying costs (e.g. depending on tank size)

7. 3” Bulkhead Fitting -
£120.00
3” Male Adaptor - £10.00

8. 4. Mini sewage treatment plant
• The next generation of septic tanks, which will conform to new regulations coming into force
01.01.2020. i.e. the quality of “discharged” water “General Binding Rules”
Large underground tanks will require expert installation and become a fixed item.
PROs
• Low environmental impact – no mains power, purely biological process
• Single moulded tanks in various sizes
• Operate even with sporadic / seasonal use
• Low running costs – servicing once very 2 years (qualify)
CONs
• Groundworks required
• Mains water required for flushing toilets
• High capital outlay

9. FACTS & FIGURES
• We each use the loo 8-10 times per day (very rough average – some more, some less).
• Each regulation cistern flush is 4-6 litres.
• British Water Flows & Loads version 4 is the guideline on water consumption (qualifty)
• Although there is no “average” person, if we drink the recommended 2 litres of liquid per day, we will
urinate about !½ litres. There will typically be one bowel movement.
• Use of composting toilets and chemiloos could save an estimated 8-10 flushes x 6 litres per flush =
48-60 litres per person, per day IF they are on site all day. You will need to make an adjustment for
time duration and visits whilst children are on site.
• Use of standard toilets requires water to be made available – but will also effect easier hand washing
and “tidying” up in the event of soiling issues with kids.
• Roughly 7-10 people per toilet as a guide to determine number of toilets.
