Pipeline infrastructure renewal at Miami-Dade Water & Sewer Department

by Pure Technologies  (Nov. 18, 2014)

Abstract Various governmental, professional and private studies have shown that the replacement costs of underground pipeline infrastructure is excessive and that best practice approaches for infrastructure risk management promote condition assessment programs to understand the actual condition of individual pipe sections in order to best allocate ...

Comparing the utility of decision trees and support vector machines when planning inspections of linear sewer infrastructure

by IWA Publishing  (Nov. 10, 2014)

Closed-circuit television inspection technology is traditionally used to identify aging sewer pipes requiring rehabilitation. While these inspections provide essential information on the condition of pipes hidden from day-to-day view, they are expensive and often limited to small portions of an entire sewer system. Municipalities may benefit from ...

Quick and accurate Cellular Automata sewer simulator

by IWA Publishing  (Nov. 10, 2014)

As urbanisation and climate change progress, the frequency of flooding will increase. Each flood event causes damage to infrastructure and the environment. It is thus important to minimise the damage caused, which can be done through planning for events, real-time control of networks and risk management. To perform these actions, many different ...

Case Study - Sewer Sensors

by Solid Applied Technologies Ltd.  (Sep. 10, 2013)

Sewer Sensors Sewer sensors are offered by Solid Applied Technologies for remote level monitoring. The sesnors are ultrasonic, non-contact with no moving parts. The system is equipped with an external battery pack and can operate at a low-power-mode for long term life. The sensors are equipped with embedded GSM cellular modem and act as M2M ...

Risk assessment of sewer condition using artificial intelligence tools: application to the SANEST sewer system

by IWA Publishing  (Feb. 19, 2014)

Operation, maintenance and rehabilitation comprise the main concerns of wastewater infrastructure asset management. Given the nature of the service provided by a wastewater system and the characteristics of the supporting infrastructure, technical issues are relevant to support asset management decisions. In particular, in densely urbanized areas ...

Sewer Level Monitoring - Photos

by Solid Applied Technologies Ltd.  (Apr. 11, 2013)

Sewer Level Monitoring - Photos Photos in this article present the complexity and versatility of sewer level monitoring. When examining the photos, pay special attention to the stand-alone autonomous characteristics of each installation. In lack of any cabling from the outside, whether data cables or power cables, the solution is fed from its own ...

What`s in the numbers? a review and analysis of more than 400 miles of force main inspection and condition assessment data

by Pure Technologies  (Nov. 18, 2014)

Abstract Comprehensive condition assessment of wastewater force mains provides significant challenges to owners/operators of collection systems as the ability to shut down or expose the pipeline for a thorough inspection is often impractical due to operational and/or financial considerations. Traditional gravity sewer inspection techniques (i.e. ...

Innovative use of lamella clarifiers for central stormwater treatment in separate sewer systems

by IWA Publishing  (Apr. 24, 2014)

Lamella settlers have been used in the past few years for the sedimentation of particles in wastewater and stormwater applications. A new and very innovative approach for the treatment of stormwater flows is proposed which extends the portfolio of solutions beyond traditional settling tanks. Surface runoff is stored in a sewer or a basin and ...

Cost-effective solutions for water quality improvement in the Dommel River supported by sewer–WWTP–river integrated modelling

by IWA Publishing  (Sep. 16, 2013)

This project aims at finding cost-efficient sets of measures to meet the Water Framework Directive (WFD) derived goals for the Dommel River (The Netherlands). Within the project, both acute and long-term impacts of the urban wastewater system on the chemical and ecological quality of the river are studied with a monitoring campaign in the urban ...
