Topics to be covered include:

  • The reality of monitoring, regular cleaning, and annual/comprehensive cleaning
  • Quick coverage of 90% of proprietary devices
  • A more detailed focus on the 4 devices that have 90% of the market
  • Cleaning specifications for these – to include in tenders, and be used on the ground

  • Dewatering – a problem for every site
  • Field validation of performance, cleaning results
  • GPT auditing and WSUD auditing
  • Costing – how much should cleaning cost
  • Budgeting and bean counters – how to get the money to do it right
  • Results, reports and record keeping – why
