Globally, tanks play a major part in the provision of access to clean drinking water human population. Beyond aiding supply fresh water, are also essential for ensuring good sanitary conditions people and livestock. Many countries have realized that robust sanitation infrastructure necessary sustainable growth. Therefore, there is large demand construction storage tanks. Further, liquid crucial...

In many Mediterranean countries, users store water resources in private tanks, which are typically located on rooftops. These local reservoirs are generally connected directly to the water distribution network (WDN). This installation scheme causes a disconnection of the WDN from the users, and thus, the users’ water supply is no longer linked to their consumption, which changes the network ope...

As stormwater flows are intermittent, the requirement to store urban runoff is important to the design of a stormwater re-use scheme. In many urban areas, the space available to provide storage is limited and thus the need to optimise the storage volume becomes critical. This paper will discuss the advantages and disadvantages of two different approaches of providing storage: 1) a single storag...

As in many other cities, urbanization coupled with population growth worsens the water supply problem of Addis Ababa, Ethiopia, with a water supply deficit of 41% in 2016. To investigate the potential contribution of rooftop rainwater harvesting (RWH) from large public institutions, 320 such institutions were selected and grouped into 11 categories, from which 25-30% representative 588 rooftops...

−− This contribution presents a new Constraint Programming (CP) formulation to address the optimal operation of multiproduct continuous processes. In particular, facilities having continuous stages, which manufacture intermediate or final products and a limited number of intermediate storage tanks, are tackled. The problem involves finding (i) the optimal sequence of production runs and (ii) th...

Domestic Hot Water (DHW) storage tanks are identified as a main source of flexible energy use in buildings. As basis for management apartment buildings, this paper describes the aggregated DHW case building, and analyses potential flexibility by simulating different control options. The study work is an building Oslo with 56 apartments shared system. Energy measurements available consumed hot w...
