Treated recreational water
Natural water
Drinking water

Water fit for human consumption is called potable water or drinking water. Water that is not fit for drinking but is not harmful for humans when used for recreational purposes may be called various names including treated recreational water or natural water. In Western Australia different types of water are regulated or monitored by different government departments.

Treated recreational water
Aquatic facilities
All aquatic facilities, as defined in the Health (Aquatic Facilities) Regulations 2007, must close. Pool use for essential medical / allied health requirements remain exempt. 

Backyard swimming pools in a residential property are not considered a public swimming pool, however only members of the household would be permitted to access it.

Natural water
Beaches
Beaches are monitored by the Department of Health with support from local government.

The City’s four beaches (Bathers Beach, Leighton Beach, South Beach and Port Beach) are sampled during November to April for bacterial quality as part of the state government’s annual health swimming survey.

The City’s beaches have each recorded a green beach grade over the past years of sampling. This means that the water quality is of a high standard and is safe for swimming. The results of testing are collaborated yearly with other local governments and displayed on the healthy swimming website.

The estuary and rivers
The estuary and rivers are monitored by the Swan River Trust and Department of Water. The Swan River Trust and Department of Water, conduct routine water quality monitoring at more than 30 sites spread throughout the estuary. The Swan River Trust also monitors the water quality entering the Swan and Canning rivers.

For further information on natural waterways visit The Department of Water and Environmental Regulation website. 

Drinking water
Scheme water
Scheme water is supplied and tested by the Water Corporation of Western Australia, managed by the Department of Water and regulated by the Department of Health.

For information on drinking water, guidelines and links to resources, visit the Department of Health’s website. Or for information on the supply and monitoring of drinking water visit the water quality section of the Water Corporations website.

Rain water tanks
Rain water tanks are an excellent source of providing non-potable water to your household for the toilet and laundry, washing your car and watering the garden. 

In terms of the City's position on water sustainability for new developments, please refer to local planning policy 2.2 part A clause 3 and part B - Water. The City's policy recommends that new lots developments include installation of at least a 3000 litre rainwater tank plumbed to the toilet or washing machine.


What are the types of water quality?

Water quality can be classified into four types—potable water, palatable water, contaminated (polluted) water, and infected water.

Why is water quality important?

Life on our planet is highly dependent on freshwater. Freshwater is a scarce resource and is a very small fraction of all water on the planet. While nearly 70 percent of the world is covered by water, only 2.5 percent of it is freshwater. The rest is saline seawater. Even then, just around 1.2 percent of our freshwater is easily accessible, as much of the 2.5 percent of total freshwater is trapped in glaciers and ice caps (68.7 percent) and groundwater (30.1 percent). Preserving the quality of freshwater is essential to prevent harm to human health and to the aquatic ecosystems, from which we get many other benefits such as drinking water, food and recreation.

What is the World Water Quality Alliance and what is its role?

The World Water Quality Alliance (WWQA), represents a voluntary and flexible global multi-stakeholders network that advocates the central role of freshwater quality in achieving prosperity and sustainability; it explores and communicates water quality risks in global regional, national and local contexts with the aim of pointing towards solutions for maintaining and restoring ecosystem and human health and well-being, with an aim to serve countries throughout the lifetime of the 2030 Agenda for Sustainable Development and beyond. The WWQA aims to provide a participatory platform for water quality assessments and co-design of tailored and demand-driven services.

Environmental pollution

 By Maina Gam Abstract Our environment faces several problems and many of these seem to be worsening with time, bringing us into a time of a true environmental crisis. Therefore enhancing public awareness of these problems is essential to lessen their detrimental effects. Environmental pollution is increasing day by day and imposing severe and irreversible damage to the world. It is of different types: air, water, soil, noise, light, etc. Urbanization and technological development have put the survival of the planet in danger by degrading the quality of the environment’s essential elements—air, water and soil—due to the release of hazardous waste from factories like plastics, heavy metals, nitrates, burning of fossil fuels, acid rain, oil spills and industrial toxins. Urbanization and overpopulation have increased city noise and light pollution. Polluting agents are exponentially increasing in modern society, disturbing the ecological balance and posing extinction problems for diff...

Water Resources

Water Resource    Water resources encompass the freshwaters of the world, which include precipitation falling as rain or snow, infiltrating into soils and groundwater aquifers, running off into stream networks, evaporating from lakes and transping from vegetation, and flowing back into the deltas and estuaries along the continental margins. The geographic distribution and flow of freshwaters (analyzed through water-budget studies) affect supplies available for human use, and associated problems of surplus, scarcity, and pollution. Psychological and behavioral research has focused on perception of water problems, flood risks, drought hazards, and decision-making models, while phenomenological research has explored deeper meanings of water experience. During the twentieth century, social scientific research on water evolved from description of regional water problems (e.g., in the Tennessee Valley Authority); to economic and institutional analyses of water rights, water markets,...
