Water enters through a screened pipe located deep underwater in Long Pond.
It then travels more than half a mile through a pipeline along this path
in the woods
to the treatment plant on Punkinville Road.
The piping in the plant is color-coded and named (raw water, filtered water,
The turbidity of the raw water is measured and recorded.
pH adjustment is made and coagulant added to prepare the water for
Water is filtered through a tank
operated through the above control panel.
Chlorine is added to the water after filtration.
Treated water is pumped to an in-house storage tank (blue pumps). Backwash
water is pumped to an outside drying bed (tan pumps).
Chlorine residual, pH, and turbidity in the treated water are measured and
Water is then piped from the storage tank at the plant to storage in a s
tandpipe located at the highest altitude in Sorrento.
Solar panels supply the power to measure the water level in the standpipe
and transmit this information through short wave radio to the SCADA
system at the plant.
The SCADA system takes real time data about turbidity, chlorination, water
levels, and so on from the monitors in the plant and at the standpipe,
and displays them on the computer. The operator can then adjust treatment
as necessary using computer controls. The operator is even able to access
the SCADA system on his cell phone when he is not at the plant.
