The Economics of Green Water.

Average Water Consumption per person = 150litres per day.

This is equivalent to about 55m3 (or tonnes) per year.

A 6 person household therefore uses about 350m3/ year.

40% of this is used for toilet flushing and garden irrigation.

The Code for Sustainable Homes seeks to reduce this to about 105 litres per person per day.

Water Works UK

Water Works UK is a company which can act as Consultant, Practitioner or Supplier primarily of 'Green' (non-potable) water for new developments (such as new towns, areas or communities).

WWUK works with Local Councils, ALMOs and Housing Associations to provide a secondary, fit-for-purpose parallel (to the potable) supply for :

Water for a Green City

A water supply needs to be wholesome, guaranteed and appropriate for the purpose for which it is required.

At least 50% of the water consumed in the home and workplace does not need to be of drinkable quality.

Water Works UK will supply the right quality water for the purpose at the right price.

Water Works UK is concerned with:

This involves the strategic development and provision of a sustainable, parallel, non-potable 'green' water supply for applications which do not require drinking water quality - principally toilet flushing and garden or landscape irrigation.

This approach ranges from the networked supply of groundwater to larger communities to the utilisation of rain water and greywater recycling (to 'green' water) at small and medium scale installations.

Water Works UK works with forward-looking, acclaimed developers, architects, engineers and builders to produce an effective, low-maintenance localised and modular roof based cleansing system for the recycling of urban water (GROW and GROW 2).

The company is particularly concerned with grey water collection and treatment in multiple occupancy, multi-story housing urban regeneration areas, with a view to reducing water costs to customers through the appropriate reuse of such water. Once treated, it is termed 'green water'

WWUK is engaged in cutting-edge research with a number of industrial and academic partners on suitable biological treatment systems for converting 'grey water' to 'green water' that only require the very minimum of chemical additives – e.g. chlorine, or no additives at all such as UV treatment. The fruits of this research will shortly result in an attractive and marketable system for green water production suitable for 21st Century urban dwellings.
