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 need to develop a flexible integrated water management package for all new development sites in the UK is becoming an urgent priority if we are to derive maximum beneficial balance between the requirements of civilised living, the capacity of nature to provide and the ability of people to reasonably pay for water and waste water services.”

“AWS has twenty years of experience of seeking and providing environmentally friendly solutions which engage people in the achievement of these outcomes. Some of this activity was carried out under the auspices of The Metropolitan Water Company, and WWUK prior to AWS.”
