Urban Water Systems

The vast majority of the world’s population today is living in an urbanized environment and the trend of people moving to cities continues to grow. Thus a large proportion of human water consumption and wastewater discharge occurs in urban space.

Raw or treated water, often supplied from remote sources, is frequently stored in urban supply areas to serve as a buffer at times of peak demand or interruption of bulk supply, before being distributed to consumers through (mostly) pumped network systems.

For modern water distribution systems, it is essential to make water of sufficient quality, quantity and pressure available at all times. Today, substantial water losses caused by aging supply networks jeopardize the supply reliability and increase the supply costs. Apple Vision is committed to working with clients around the world to tackle leakage and employ the latest know-how in efficient supply concepts and technologies to make the most out of the world’s precious fresh water resources.

When it comes to collecting wastewater, either in dedicated separate systems or together with storm water in combined systems, Apple Vision can deliver master plans, feasibility studies or complex system designs. In addition to the design of new systems, increasingly significant public and private investments target the expansion and rehabilitation of existing sewer systems with the goal of maximizing the use of available system components.

But Urban Water is not just about the human demand for potable water and the resulting generation of wastewater, it is increasingly about the management of rain water and specifically extreme surface runoff. Conventional combined or separate drainage systems have for long sufficiently addressed the capturing and safe assimilation of this water into the environment. However, the rapid expansion of impervious surfaces in combination with the widely observed change in weather patterns that has resulted in greater rainfall intensities and durations now necessitate alternative approaches. Hence, Apple Vision is promoting integrated surface water management in urban environments – local ground infiltration, decentralized retention in cities and safe routing through urban agglomerations. To this end Apple Vision employs the latest 1D/2D coupled modeling technology to make urban space both safe and livable.
