General Description Many wastewater utilities use an abbreviated period of the year upon which to base the calculation of customer account sewer charges. However, the recalculation of the actual charge usually does not occur for some time after the period of the rate calculations. The actual rate...
First of all calculate the average sewage flow on the basis of water consumption and the population at the end of the design period. i.e at the full development of the area. Then the design flow for sanitary sewer and partially combined sewers can by calculated by using the following formul...
Mercury is used, usually in very small amounts, as a preservative or antibacterial agent in a number of over-the-counter and prescription pharmaceutical products. These include: antibiotics; blood pressure cuffs; contact lens solution; dental amalgam; diuretics; ear and eye drops; eye ointment; h...

The City of Chattanooga installed a permanent network of flow monitors for revenue billing applied to its regional customers. In addition to improving the accuracy of bill calculation, the city also discovered capacity problems at several locations. The City of Nashville has maintained a long-term ...
Initially, a stable flow is developed in a computational mesh representing a sewer before the introduction of suspended sediment in the form of an inlet concentration and the calculation of a bedload transport rate in the cells of the mesh representing the deposited bed. Subsequently, the ...
The repeated calculation approach has been implemented in various studies to reduce the effects of random weight initialization of the LSTM model [60]. Therefore, the training of each LSTM architecture was repeated 20 times to make a comparison between different LSTM models in this study. The ...
Apart from the calculation of the RII, each defect’s risk value (RI) was calculated. The RI was derived by multiplying the probabilities of occurrence and impacts determined by the experts’ judgments, which yielded the RI, using Equation (2) [34]. 𝑅𝐼=𝑃×𝐼RI=P×I (2) wh...
At this point, it should be noted that with the chosen approach, the water level and flow rate at all measuring points are calculated based on a precipitation load using a clearly defined calculation method implemented in the hydrodynamic modelling software (Mike+ 2021, update 1) used. ...
In this approach, the capacity of each conduit in a hydrodynamic model is reduced to (almost) zero and the hydraulic consequences are determined. For large (> 5000 conduits) (looped) systems both methods require a large calculation effort. This paper proposes a new approach towards identifying ...
