When sourcing a water treatment solution or partner it can be difficult to know exactly what or who you're looking for. Kelly Tanks specialise in simplifying this process by offering expert advice, impeccable solutions and unrivalled aftercare services.


So lets start with the basics...


Why do Construction sites need to treat their onsite waste water?


  1. Environmental Protection: Untreated wastewater can pollute water bodies, harm aquatic life, and contaminate soil. Treating wastewater helps protect the environment by removing contaminants and pathogens before discharge into waterways or soil.


  2. Compliance with Regulations: Construction projects must comply with environmental regulations to avoid legal issues. Treating wastewater ensures that companies meet these standards, which are designed to protect both public health and the environment.


  3. Water Reuse: Effective wastewater treatment allows for the reuse of water, which can be beneficial for construction activities. This reduces the demand on potable water resources and minimises costs associated with water procurement.


  4. Public Health: Untreated wastewater poses significant health risks, including the spread of diseases.. Treating wastewater on-site helps prevent these health hazards by removing contaminants.


  5. Cost Savings: On-site treatment can reduce costs associated with disposal and transporting wastewater to off-site treatment facilities.


What do Construction sites need to consider when choosing how to deal with their onsite waste water?


Where possible, sites should minimise the amount of waste generated and recycle.


Discharge usually goes to foul in accordance with the sites Trade Effluent Consent; where not possible, discharge would have to go to water course in accordance with an Environmental Permit. Discharge to water course has stricter consent requirements which require much higher standard of treatment and smaller quantity of discharge.


Sewage Undertakers place strict limits on concentration of suspended particles as they may cause blockages.


Majority of Trade effluents are mostly; water, a small amount of solids, a smaller amount of dissolved Inorganic Chemicals (eg. calcium, sulphate, cyanide, lead, copper) and smaller amount of ‘other’.

 

Trade effluent consents commonly include limits on:

  • Flow Rate

  • Total Daily Volume

  • Time of Discharge

  • Temperature

  • pH

  • Toxic Metals

  • Hydrocarbons

  • Suspended Solids (Totally Suspended Solids TSS)

  • Sampling and Monitoring

  • Chemical Oxygen Demand (COD)



How can Kelly Tanks help?


We keep it simple; our WTS systems are Lamella/Coalescing style Clarifiers which are more efficient than conventional settlement tanks due to the increased settlement area created by the Lamella/Coalescing media.


  • Coalescing/lamella media for a huge settling area

  • Silt and sludge collected in hopper for easy removal

  • Adjustable oil skimmer for hydrocarbons

  • Simple to set up, simple to empty, simple to operate

  • Large Hoppers for retaining settled solids

  • Solids are emptied via dump valve for easy removal and cleaning

  • Can be used with or without flocculant

  • Can be fitted with remote water quality monitoring

  • Can be fitted with auto desludging pumps

  • Can be fitted with pH dosing equipment



Why us? Settling the debate.


  • Interchangeable lamella/coalescing media that can be provided with different diameter openings making it perfect for any application due to it's customizability and adaptability for varying loads.


  • Cleaning media like this can be tough in an enclosed system, so at Kelly Tanks, our media is surrounded by a cage that completely lifts out of our WTS to make

    cleaning and maintenance of the media effortless.


  •  The chevron shaping of our media results in an equidistant flow meaning a consistent flow rate and provides a larger effective settling area as well as preventing clogging of the system.


  • The simplicity of our WTS with no moving parts results in a painless set up and robust system. Silt and sludge is collected in the hopper for easy removal via the dump valve.


  • Available with a remote monitoring system with real time monitoring and data-logging to measure and record pH, turbidity, TSS and more all from your phone or desktop.
