Waitati In Flood
Waitati is home to a low lying, flood-prone community near Dunedin. Waterwatch has sponsored a programme to provide the community with up to date flood warning information.
Surrounded by tidal mudflats, the Waitati river flows through Blueskin Bay and out to sea. Heavy rainfall in the headwaters drains rapidly and with little warning to the lowland river flats, resulting in frequent flooding. More severe events have seen the Waitati township as "a single sheet of water from one side of the valley to the other".
Waitati residents up until recently would walk down the river at various times throughout the night in extreme weather events to ensure their homes and neighbours were safe.
Waterwatch is now monitoring sites along the river near properties that commonly flood. Residents are able to check the open, online platform and register for SMS or email notifications when the river is expected to flood.
Two LS1 sensors are installed on bridges like the one in the video above, one on each side of the riverbed.
How does it work?
The LS1 is a highly configurable, non-contact, ultrasonic water level sensor ideal for open channel measurements. Being waterproof, measuring with 1% accuracy and a 10 year battery life, the LS1 is the preferred option for utilities, city councils, regional governments and homeowners.
The LS1 transmits data through the Sigfox network to Waterwatch Live. Data can be viewed, stored and analysed from computers and mobile devices, anywhere in the world. Threshold based notifications can also be set up to notify users of high, low or rapidly changing surface water levels.
The Waterwatch LS1 is discrete and simple to instal, making it the easy solution to any unsupervised waterway. Waterwatch makes monitoring technology accessible to communities where traditional river monitoring equipment was cost prohibitive.
Flood protection is becoming increasingly important with destructive weather events becoming more frequent. Installing a water level sensor has the potential to save infrastructure, property and lives.
