Integrated Water Management
Integrated Water Management means more then just offering a single product solution. A holistic approach using and combining a number of different options are often better suited in helping people longer term.

Looking at the bigger picture
Water sources
Which water sources can I use? Where, when, how and in which quantity are they available? We look at all the sources and decide what are the easiest and the most cost effective ways to utilize them for different purposes.
Drinking water
There are numerous ways to purify any kind of raw water into drinking water quality. Which ones are the best depends on individual local circumstances. High Tech, Low Tech or "Appropriate Tech" or a combination thereof is a matter of clever planning and dialogue with the client.
Grey water
Grey water is waste water with limited contamination. It is usually coming from showers of the bath. Grey water can be relatively easily treated wit a number of different technologies and reused for various purposes. With simple means it is possible to reduce the quantity and the contamination of grey water so that the treatment effort is reduced accordingly.
Black Water
This is mostly the water from toilets. Apart from reducing the water required in the process of flushing to the extent of water free toilets it is beneficial in many cases to separate the content for further commercial use like soil production or liquid fertilizers. A proper decentralised sanitation concept is always cheaper to achieve then to cover the costs of a neglected sanitation. Sanitation is a crucial part of any water integrated water concept.
Surface water, groundwater
The treated water is stored as ponds or in tanks and available for further reuse. It is not considered as waste water but as a resource to be utilized again for a number of different purposes. Whether for farming, irrigation, for toilet flushing, shower or even drinking water, all depends on the requirements and the technology chosen.
Short and renewable water ways
Avoiding long distances of water infrastructure or the use of fossil fuel makes a decentralised system not only cheaper and more reliable but also safer since all the infrastructure is on site and redundant to any other system. Technical advances in monitoring systems for quantity and quality make it also safe and comfortable to maintain complete systems even in remote locations.
Typical project questions by DWC
- Water demand/ flow for toilets or water for general use
- Water demand for drinking water (including if rain water systems are used)
- Water demand totally (Pool, garden, etc.)
- Technical drawing of the site (Sanitary installation, waste water structures...)
- Space availability on site
- Current costs for drinking water and waste water treatment
- Energy costs
