  • Top 5 Differences between Micro Pulse LiDAR and Ceilometer Technology

    If you are evaluating backscatter LiDAR sensors for measuring aerosols, cloud vertical structure, and planetary boundary layer (PBL) heights, what factors should you consider in your comparison? It really comes down to a choice between the traditional analog technology used in ceilometers and the more recent advanced technology found in Micro Pulse LiDAR (MPL) sensors. ...

  • 30 Fusible PVC Pipe to Protect Community from Flooding Case Study

    As with much of Edmonton’s storm systems that collects surface water into underground pipes and conveys it to either surface watercourse, lakes, ravines or the river, the development of Keswick required a system to drain surface water and prevent ...

  • Mosaic Stadium, Regina: Home to the Roughriders and IPEX Case Study

    From the beginning the owner was interested in the use of thermoplastic piping systems for drain, waste, and ventilation (DWV), potable water and chilled water lines, but research needed to be done. After looking at price and installation-time comparisons with copper and steel pipe, the most cost-effective choice with the quickest install time was thermoplastic ...

  • Residential spill in VA

    Laboratory analysis of soil samples showed high values of TPH/DRO showing an initial value of 18,800 and 8,300 ppm and the samples of soil analyzed after treatment with VaporRemed showed a value of 290 ppm and 210 ppm. Both these values are below the stipulated 500 ppm of TPH/DRO. The TPH in the drain water after flushing with the product showed values below the detection levels. The project was ...

  • Soil Column Drainage Modelling Using a Geotechnical Centrifuge

    Equipment has been developed to facilitate supplying a soil column with water or draining a soil column under conditions of constant head while the soil column is under centrifugal forces in a geotechnical centrifuge. Accurate monitoring of the water mass transfer is also facilitated by the equipment. At the completion of a modelling sequence, the soil column may be partitioned for moisture ...

  • Rewetting of Drained Peatlands

    Canal Blocking has many benefits : Restoration of 'wet' peat characteristics and reduction of fire Return of the carbon sequestering capacity of peatland Re-establishment of the water buffer fucntion and a reduction of floads Opportunity to plant economically viable species like Jelutung for rubber and Tengkawang (illevenut) for edible oil production; it opens also ...

  • NHS Medical Centre building gets rainwater recycling system

    The development consists of a three storey medical centre building. The total roof span of the medical centre building exceeded 1,250m2. Aquaco supplied a 20,000 litre rainwater recycling system to be fed by a common rainwater collection point with an overflow to surface water drain. The system included a ground filter, dual submersible pump sets with control panel, float switches, rainwater ...

  • Keeping/ reconstituting groundwater

    In urban areas the rainwater often is (was) fast drained away. That leads to a shift in the water balance, infiltration and evaporation declined compared with the natural conditions. Caused by the missing infiltration, the groundwater level decline, which could have irreversible consequences for ecosystems like wetlands, lakes or rivers (because of missing low flow runoff). ...

  • Management of Fats Oil and Grease - FOG

    Estimates reveal that FOG reaching the nations drains causes up to 75% of sewer blockages and related floods.  The management of this waste stream is being taken increasingly seriously by the authorities, including Environmental Health Officers, The Environment Agency and the Water Companies.   Not everyone is aware of their responsibilities with ...

  • Tidal technology to stop flooding

    A large 1.6 metre valve that stops tidal waters getting into the stormwater network will help stop flooding in the city centre during heavy rainfalls.   High tidal levels and heavy rain cause problems in Porirua, New Zealand.  Porirua was the first Council in New Zealand to test the valves, which are a Scandinavian design called WaStop. The Councils Water Services Engineer Desmond ...

  • Experimental study of hydraulics and sediment capture efficiency in catchbasins

    Catchbasins (also known as gully pot in the UK and Australia) are used to receive surface runoff and drain the stormwater into storm sewers. The recent interest in catchbasins is to improve their effectiveness in removing sediments in stormwater. An experimental study was conducted to examine the hydraulic features and sediment capture efficiency in catchbasins, with and without a bottom sump. ...

  • River Basin

    A river basin is an extent of land where water from rain and melting snow or ice drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean. The river basin includes both the streams and rivers that convey the water as well as the land surfaces from which water drains into those channels, and is separated from adjacent basins by a drainage divide. The ...

  • Grease trap treatment in a meat plant

    Meat plants tend to be major producers of fats and grease and this present problems in the wastewater infrastructure as it is not soluble in water. This leads to build up in drains and grease traps and the traditional approach to disposal is to physically remove it and ship it off site for licensed disposal. A new approach is to use bioaugmentation to physically degrade the grease so that it ...

  • SurfaceInfiltration

    Surface infiltration means that runoff from impermeable surfaces (e.g. roofs) is drained on a permeable grassed area. There, the water infiltrates into the soil without retention and the main portion evaporates. Surface infiltration is especially suitable for small areas such as yards and low- traffic areas (infiltration into adjacent green space). Surface infiltration requires: Good ...
