Water is the driving force of all nature(Leonardo da Vinci)

Freshwater is only around 3% of all water on the earth - with very little of this in circulation

Freshwater Storages

• Ice and glaciers 75%

• Groundwater: deeper than 800m 13.5%

• Groundwater: less than 800m deep 11.0%

• Lakes 0.3%

• Soils 0.06%

• Atmosphere 0.035%

• Rivers 0.03%

Percentage of water in storages (including seawater)

• Ocean 93.8

• Glaciers and permanent snow 1.986

• Groundwater to 5 km depth 11.0

• Lakes 0.0051

• Atmosphere 0.000959

• Rivers 0.00008

• Biological Water 0.000005

Water - the primary resource

Without water we have no life, no productive capacity - all is dust and rock

The Water Cycle

When water “does it’s duty” in the landscape it becomes the basis of our farming and productive land

based enterprises and gives us both Water Purification and

Biomass Production

All of our work is based upon Permaculture Design Principles

andP A Yeomans Keyline System

Capture and Store Energy: The Swale

A swale is a large hollow or shallow ditch (a broad drain), which runs along the contour of a slope, which is intended to pool and then

absorb surplus water flow by infiltration - recharging groundwater.

Trees and other fibrous/deep rooted vegetation are an integral part of the infiltration process and take over this

function from the bare earthworks after several years.

Wetland Ecosystem Treatment (WET Systems)

These are constructed wetland ecosystems for wastewater purification,

resource production and habitat creation

A WET System views the ‘wastewater’ not as a ‘problem to be got rid of’, but as an unused resource which feeds the process and is converted into multiple yields including:

• Willow wands and other craft materials

• Biomass fuel and polewood

• Fruit and Nut trees as well as soft fruit

• Wildflower/wetland plant material and seed

• Nectar, Pollen and Honey

• Fish, Venison, Pheasants

A WET System is a Horizontal, Plug-flow, Soil-Mycorrhyzal, Multi-species

Purification and Production System

• A WET System uses the metabolic processes of the microbial species - which live in a beneficial symbiosis with the plants and trees within the system.

• It is this ‘processing ability’ which purifies the wastewater passing through the WET System.

A WET System also sequesters carbon dioxide, by the creation

of soil as well as plant and microbial biomass.

For the past 2o years Biologic Design has planted between 5,000

and 100,000 trees each year on our WET Systems

A WET System does not use gravel as the purification medium and

neither does it use large quantities of plastic pipework.

The working lifetime of a WET System can be measured in decades,

perhaps centuries!

Bioengineering in action

A WET System is a ‘bioengineering’ design solution which uses biological

‘components’ - both plant andmicrobial communities -

to accomplish the required ‘engineering functions’ of wastewater

purification, odour control and soil stabilisation

Here are the fruiting bodies of just some of the tireless

‘willing-workers’ (the fungi, slime moulds and mycorrhiza)

who are busy, on the job 24 hours a day - and who require no pay and take no holidays!

So a WET System is a wastewater purification system created and

planted specifically to provide not only clean water with minimal or no non-renewable energy use, but also to produce a useful economic yield.

What if we harvested and stored rainwater in a series of productive

swales with similar intent on a farm or a smallholding?

“The Crossing”

A Whole Site Water Reticulation,

Agroforestry/Silvopastoral Production System

The site’s design and planting gives greater resilience to the landscape, its

aim to create soil (with a healthy fungal and mycorrhizal population)

This is to enable a more varied production potential and to both

minimise soil erosion and maximise the potential for soil regeneration - especially if it proves that the grazing regime works

as well in creating deep soil in the temperate zone as it does in more ‘brittle’

environments.

With this series of swales in place the layout on site is moderating the worst excesses the

weather can give us.

Water is held on site so that we have more water available in drought conditions, and also by

holding water in the swale ditches and increasingly in the deepening carbon rich soil - which acts as a sponge - the regime causes less

risk of flooding downstream.

Water flows through the site is along a well-delineated flow pattern, this being planted and therefore enabling more productive landscape which is not prone to either drought or flood.
