Coping with uncertainty in sewer system rehabilitation
نویسنده
چکیده
In decision-making on sewer rehabilitation risk and uncertainty are not taken into account. However, the assessments on which the decisions are based are considerably affected by uncertainties on external inputs, system behaviour and effects. In this paper, a risk-based approach is presented considering uncertainty in sewer system dimensions, natural variability in rainfall and uncertainty in the cost function describing environmental damage. The use of risk based optimisation is illustrated with an example.

Influence of model parameter uncertainties on decision- making for sewer system management
Decisions on the rehabilitation of a sewer system are usually based on a single computation of CSO volumes using a time series of rainfall as system loads. Therefore, uncertainty in knowledge of model parameters is not taken into account. Moreover, statistical uncertainties are left aside. This paper presents the effect of uncertainties in model parameters on overall model results taking into a...
متن کاملQuantification of sewer leakage: a review.
One of the goals of the APUSS project (assessing infiltration and exfiltration on the performance of urban sewer systems) is to assess sewer exfiltration, in order to support cities and operators to define problem-oriented rehabilitation strategies. In this paper, we review various methods currently used for the estimation of exfiltration and discuss data needs and applicability for rehabilitat...

If all parameters influencing sewer performance were known (or deterministic) then the decision making process associated to the planning of sewer replacement should be relatively straightforward. However, when trying to forecast service life, uncertainties arise considering the deterioration process, the variability of sewer pipe properties, environmental conditions or the used information res...

Considering the complex nature of the measurand and the metrological requirements of local installations, the best available level of accuracy in measurement results should be sought....
متن کاملCollection Systems O & M Fact Sheet Trenchless Sewer Rehabilitation
DESCRIPTION As the infrastructure in the United States ages, increasing importance is being placed on rehabilitating the nation's wastewater treatment collection systems. Cracks, settling, tree root intrusion, and other disturbances that develop over time deteriorate pipe lines and other conveyance structures that comprise wastewater collection systems. These deteriorating conditions can increa...
