If you know something about a NatSol toilet which seems worthy of a post on this page please let us know.

Compost toilet maintenance

Aware that our compost toilet instruction booklet shows our old MK 1 pedestal, we decided to visit Hollow Ash Shepherd’s Hut Holidays for a photoshoot now that their peak camping season is over.

It is always good to have an excuse to visit installations and to meet our customers for feedback. We also like to see what people have done to customise their toilets and this is a fine example!

The shepherd hut based toilet building is looking great after two seasons of campers.

Waterless Toilet System for Busy Sites

Richmond park waterless toilets

In 2012 NatSol was chosen to design a toilet system for a new accessible facility in the Isabella Plantation, Richmond Park, London. The toilets opened to the public in Sept 2014 and are working well. We are monitoring performance and are looking to develop this approach for other high use sites.

Toilets for an SSSI

The Isabella Plantation is a Site of Special Scientific Interest (SSSI) with high ground water and heavy clay soil where no foul discharge to ground is permitted. Waterless toilets seemed like the obvious choice but we have long held reservations about composting toilets as an appropriate technology for very high use public sites because of the need to manually remove compost. This has not been a problem on lower use sites. Even busy allotments produce surprisingly little solid waste thanks to the twin vault process.

In consultation with The Royal Parks (TRP) and the design team of engineers and architects we developed a waterless system with individual tanks beneath the toilet pedestals. These can be emptied by tanker four or five times a year.

Odourless loos

The waterless toilets are ventilated via the specially designed stainless steel pedestals removing odour at source. The air is drawn through a biological odour filter developed by NatSol. The filter was included to ensure odour-free operation in an area sheltered by trees. The extra resistance of the filter meant that we needed to use an energy efficient fan rather than our usual passive vent chimney that has proved so successful on our dry composting toilets.

In addition to the five toilet pedestals the gents includes AIRFLUSH® Urinals developed by NatSol Technical Director Nick Grant and supplied by the Green Building Store. GBS also provided help with the efficient ventilation design.

The design fulfils TRP’s requirement for a low water use toilet block with excellent odour control, no site discharges, low management requirement and infrequent emptying.

NatSol Compost Toilets is Ten this Year!

Ten 10 years of supplying toilets for off mains sites

Now that we have recovered from the shock of how fast 10 years can fly by we are enjoying this important milestone. During this period we have been pleased to provide wheelchair accessible toilet facilities for an increasingly diverse range of off-mains sites from allotments and village churches to public parks. After ten years and over 400 compost toilet installations, we are very confident in the concept, which remains largely unchanged.

Hollow Ash Shepherd’s Hut Holidays

New Compost Toilet looking really good

A full access NatSol compost toilet forms the base for a very lovely new installation for a luxury camping (glamping) set up in Herefordshire. We are always pleased when customers want to design their own building and we have designed the vault so that it forms the foundations and floor to make this a relatively simple option. As you can see, this is a particularly fine example by Jeremy Harris of Hollow Ash Shepherd’s Huts.

The best compost toilet just got better

Small changes to our compost toilets give a fresh look

Stainless steel urine diverting compost toilet pedestalDesigning the new stainless steel pedestal gave us the chance to revisit the floor design of our twin vault toilets as a new mould was required to accommodate the slimmer pedestal. The MK2 used standard galvanised steel inspection covers for the resting vault pedestal position and for compost removal hatches. These have worked very well but the fiddly locking screws are easily lost and, well, they look like inspection chamber covers!

GRC compost removal hatches

Compost toilet hatchThe new hatches are moulded from the same glass reinforced cement (GRC) as the compost chamber and building floor. They give a neater appearance and an easy to sweep and mop surface. Removal is with a special lifting key and being made of GRC they will not corrode. However if you have our previous model, there is no need to worry about spares as they are a standard item that we will continue to stock (although we have yet to see any significant problems with corrosion).

As with the floor they can be left in their natural state or sealed with stone-oil or floor-paint to suit the required decor and usage.

It has been great working with BCM GRC who manufacture our chambers. They have taken great care in getting all the details just right and are, we think, rightly proud of the result!
