Aquaco were asked to provide a solution for rainwater and grey water harvesting.
Our response

• Aquaco proposed a system consisting of an in-line 18 cubic metres per hour multi media filter vessel complete with skid and pump sets for through put and timer backwash facility to foul drain
• This system removes and retains a wider range of particle size than other designs currently available as shown
• The automated multi media filter has the benefit of an automated backwash facility, purging the system as necessary
• The 12,000L post treatment tank has two raised chambers, one of which can be isolated for maintenance at any one time
