Background topic Master Class

Safe drinking water is a basic necessity of life. In the big cities of Indonesia there are treatment plants and distribution networks to provide cheap and safe drinking water to the citizens. People in cities sometimes switch to bottled water because they think the quality of the tap water is not good enough. Bottled water is 300 times more expensive than tap water. So it is important to maintain the confidence of the customers by improving the quality continuously. Another problem is that a number of surface water treatment plants are not producing according to the design capacity. Insight in the treatment process can increase water production without large investment costs.

In rural areas there is no distribution network and the source for drinking is from either ground water wells or surface water. About 50% of the population is not connected to a centralized water system and thus drinking water which is possibly contaminated with pathogens and/or micropollutants.

The following topics are relevant:

• How can the part of the population that is not connected, improve the water quality before using it as drinking water?
• How can the quality of tap water be improved now and in the future in order to maintain customers confidence?
• How can the amount of water produced by the big surface water treatment plants be increased to the design capacity?

The master class will provide an overview of possible technical solutions for these topics.

Contents Master Class and goal

The goal of this master class is to provide an overview of technical possibilities to improve the drinking water of connected and non-connected people.

The focus will be on:

• Conventional surface water treatment as used in the big treatment plants in urban areas. So processes like coagulation, sedimentation, rapid sand filtration and disinfection are discussed.
• Small household water treatment systems to improve the drinking water quality in rural areas.
