  • The effect of pipe collectors in reducing the drainage coefficient rate

    A high groundwater table and soil salinity, especially in arid regions, often cause serious problems for agriculture. In irrigated areas the subsurface drainage can be an effective technique to lower the depth of the groundwater table and reduce soil salinity. In drainage systems, lateral pipes are designed to collect the free water from soil and convey it into collectors. In other words, ...

  • Heap leach drainage design

    Heap leach operations have gained popularity in the past around the world as a reasonable method for extracting metals such as gold, copper, and nickel from earth material. In such heap operations, however, the success of the leaching operation depends on the flow regime established by the sprinklers at the top of each lift and the drainage system at the bottom.Each lift represents a unique ...

  • Seven Ways Your Facility Isn’t Meeting Effluent Regulations and How to Solve Them

    Whether you own, operate, or help manage a municipal or industrial facility that deals with wastewater, it’s important to understand how wastewater treatment can play a significant role in the overall health of your business, especially when it comes to meeting effluent regulations. This is an important part of the wastewater treatment process to consider, as ignoring it could earn your ...

  • Ground drainage with Filtram

    The A11 Thetford Bypass comprises approximately 7.5km of single and double carriageway. The design called for a roadside fin drain system to act as a vertical water flow interceptor in conjunction with a horizontal under channel drainage layer incorporated within the roadbase. The combined system discharges to conventional drainage outlets. Filtram 1B1 -ED was chosen as the vertical fin drain and ...

  • Analytical solution for the flow velocity and water surface angle in drainage and sewer networks: case of pipes arranged in series

    Drainage and sewer network runs mostly under free surface flow condition. Among the characteristics which are important for practitioners are the flow velocity and water surface angle. The computation of these parameters in partially full pipes using Manning equation is implicit and requires iterative and laborious calculation methods. The goal of this paper is to provide a new method, where the ...

  • What is so hard about drainage modeling?

    Drainage modeling often suffers from the misconception that it is simple, but while it appears obvious that rain water will flow to the lowest point, the physical processes involved are not always well-understood or predictable. Drainage models attempt to predict that part of the water cycle that involves rainfall and its consequences, including potential flooding. Although flooding is, at its ...

  • Rainstore3 Installation Instructions For Stormwater Drainage Detention & Retention with Geotextile Fabric

    This document describes how to properly install the Rainstore3 water storage system with geotextile fabric for stormwater drainage detention and retention. Detention allows for short-term storage and release of storm water through outlet pipes. Nearby water treatment plants may have a limited capacity for handling storm water and thus, stormwater needs to be temporarily detained on site. ...

  • Experimental and numerical investigation of interactions between above and below ground drainage systems

    This paper presents the results of the experimental and numerical investigation of interactions between surface flood flow in urban areas and the flow in below ground drainage systems (sewer pipes and manholes). An experimental rig has been set up at the Water Engineering Laboratory at the University of Sheffield. It consists of a full scale gully structure with inlet grating, which connects the ...

  • Multi-objective rehabilitation of urban drainage systems under uncertainties

    Urban drainage systems are subject to many drivers which can affect their performance and functioning. Typically, climate change, urbanisation and population growth along with aging of pipes may lead to uncontrollable discharges and surface flooding. So far, many researchers and practitioners concerned with optimal design and rehabilitation of urban drainage systems have applied deterministic ...

  • 1D & 2D modelling of urban drainage systems using xpswmm and Tuflow

    Introduction: The release of a revised New South Wales (NSW) Floodplain Management Manual in 2001 established a new direction for urban flood management in NSW. This new direction was created by a redefinition of the floodplain as the area bounded by the Probable Maximum Flood (PMF) – this poses a challenge to estimate PMF flooding in highly urban areas and particularly in piped ...

  • Assessing the potential of using telecommunication microwave links in urban drainage modelling

    The ability to predict the runoff response of an urban catchment to rainfall is crucial for managing drainage systems effectively and controlling discharges from urban areas. In this paper we assess the potential of commercial microwave links (MWL) to capture the spatio-temporal rainfall dynamics and thus improve urban rainfall-runoff modelling. Specifically, we perform numerical experiments ...

  • Rain water meets thermal water – Drainage system in wellness-oasis

    The new “Kristall swim and health spa” in Ludwigsfelde is going to be the “finest spa resort” in Europe, the investor believes. On 4 November 2005, only five months after laying the foundation, the work was finished. The celebration crown was mounted on top of the wooden frame for the transparent dome roof, under which visitors will enjoy Mediterranean wellness delights. 300,000 visitors are ...

  • Use of InfoWorks CS to build an integrated urban drainage model

    Creation of a single integrated InfoWorks CS model covering foul, surface and river systems is proving invaluable in understanding the complex interactions within a flood-prone urban catchment in north west London. The three systems had originally been held in separate models, with the foul and surface networks each modeled in InfoWorks CS and the rivers in ISIS. “There has been a lot of careful ...

  • Stormwater and Spill Management at an Iron Pipe Foundry in Texas

    ABSTRACTLarge industrial sites have had permits for storm water discharges under the NPDES program of the Clean Water Act since the mid to late 80’s. Recent emphasis has been placed on regulated facilities to prepare and implement Spill Prevention, Control and Countermeasure (SPCC) plans under the Oil Pollution Prevention Act (40 CFR 112). A large iron pipe foundry in Texas has several storm ...
