Water Management

Statewide River and Stream Management can offer a low impact waterways management systems to clear vegetation, desilt and treat water for your wetland, pond, site, waterway or project. We're committed to providing you with top-tier information, empowering you to make informed decisions and choose optimal solutions for your businesses challenges.


Service Available :

  • Vegetation Harvesting

    Using the Truxor© 5000, this low impact method allows aquatic vegetation to be cut from above water level to a depth of 2m.

  • Waterway Dredging / Desilting

    Desilt waterways using a low impact hydraulically operated dredge pump.

  • Water Treatment

    Treat your dirty water on site to legislative requirements – EP Act 1970

  • Water Quality Monitoring
    Water Quality Monitoring

    Water quality is monitored throughout each stage of your waterways management project to ensure environmental compliance

Vegetation Harvesting & Desilting of Waterways

Water Quality Monitoring

A comprehensive water quality monitoring program is conducted on site. Each site will be unique; however the plan will be to ensure the following points will be monitored prior to and during dredging & dewatering activities;

  • Receiving waterway
  • Within the waterway
  • At the dredging site
  • Dewatering tube discharge point
  • Downstream of discharge re-entering the waterway.
Water Testing

Sample testing of treated water will be conducted hourly. Tests to be undertaken will include; pH, turbidity & temperature. Water monitoring equipment used include; data logger(manta, multi-probe aqua reader). results will be compared to the Sepps (Waters of Victoria)- water quality objectives to ensure legislative requirements are met prior to discharge.

Water Treatment

  • Treatment Train
    Treatment Train

    Silt and sediment collected through the dredge enter a fully enclosed treatment train where the sludge comes into contact with an appropriate flocculant (usually Floc Blocs). Floc Blocs are a slow release flocculant that acts to bind together all fine particles (soil,silt and clays) so that they will settle out rapidly leaving clear water.Depending on the nature of the silt being pumped a secondary flocculant or a coagulant may be injected into the treatment train to ensure all sediment is settled out resulting in clean water.

  • Dewatering-Tube
    Dewatering Bags

    Treated water and sediment enter a geotextile dewatering tube through cam-lock fitting. Dewatering tubes are made of a woven geotextile that collects sediment but allows clean water to seep out through the pores of the geotextile and re-enter the waterway. The sediment held within the tube is then dried out and can be recycled. Alternatively water can be directed to a portable clarifier that allows fine particles to settle using laminar plate technology. Clean water is then passively pumped back into the waterway.

Benefits to using these methods

By undertaking vegetation harvesting, dredging, pumping to a dewatering bag and then allowing the treated water to seep out and discharge back into the waterway has numerous benefits including;

  • Small footprint with no excavation and heavy machinery.
  • Vegetation removal is targeted
  • Minimal labour
  • Cost effective
  • Minimal disturbance in waterways
  • Can be done at any time of the year
  • Avoids the need for bypass pumping
  • Silt captured in the bag can be recycled
  • Innovative, environmentally friendly
  • Low impact to both waterway and surrounding environment
