Our client, Canstruct chose a custom built surface water treatment plant to produce safe and reliable potable water for human consumption.
Client: Canstruct
Location: Northern Territory
Solution: 40ft containerised Surface Water Treatment System
Industry: Agriculture
Canstruct are constructing new and upgrading existing facilities to support industry activity that is requiring a suitable water treatment facility to cater for persons on site.
RWTS was successfully awarded the contract to supply a 40ft containerised surface water treatment system to produce safe and reliable potable water for human consumption.
When accessing the design of the surface water treatment plant we took into account some key consideration based on site specific risks and project requirements.
Requirements for the WTP for this application were as follows:
CUSTOM BUILT WATER TREATMENT PLANT
RWTS designed and constructed a surface water treatment plant with a nominated design flow rate to provide a minimum of 75,000 litres per day.
The nominated recovery range for this system was 85% – with a worst case expected recovery during very high solids loading periods of 55%.
Raw water required for the 20 kl per day potable water was between 88,500 litres per day minimum and as high as 136,000 litres per day – depending on raw water quality.
There was several stages of the water treatment process implemented into the design and construction of this customize water treatment plant including;
OVERVIEW OF DESIGN AND SYSTEM FITOUT
The following key summary points outline the fitout of the system:
The water treatment system included a Grundfos CRIE15 Series duplex multistage pump set complete with variable speed drive motors. A PID Pressure targeting software control via an Allen Bradley PLC/HMI package was installed.
The pump set was sized to ensure each pump delivered 15l/sec @40 mtrs delivery head, allowing a duty standby control methodology, which allowed a final duty achieved of 10 ltrs second at 400 kpa.
A flow meter was installed on the treated water delivery line out of the system to monitor discharge flows. This would ensure the data logging of usage volumes and peak flows as well as ensuring if there were any issues an alarm would be triggered to alert operations immediately.
There was significant consideration into the site-specific risks for treatment and delivery in design and construction to ensure the final filtered and disinfected water in potable water storage complied with the Australian Drinking Water Guidelines (ADWG).
RWTS delivered a potable water treatment plant that provided a daily minimum of 75,000 litres of safe and reliable potable water for human consumption.
The water treatment system was designed and fabricated in a transportable/semi-permanent or permanent installation arrangement to provide continuous service with the required maintenance for a 20 year life expectancy.
