IMPORTANT ALGAE BLOOM NOTICE TO CUSTOMERS OF KERIKERI IRRIGATION

WAINGARO (Southern) DAM DISTRIBUTION AREA

 

The Waingaro dam water storage reservoir off Wiroa road is experiencing a surface algae bloom at present.

Properties in the southern part of the Kerikeri Irrigation scheme area receive their irrigation water from this source.

This includes Waimate North road, SH/10  to Bulls gorge, Kerikeri road, Inlet road and all side rides in this area.

 

The particular strain of algae bloom detected as a result of routine surveillance at Waingaro is a species capable of producing toxin, but no toxin has been detected at this stage. The algae bloom is present near the surface of the dam.

 

Algae blooms can happen in lakes, reservoirs and waterways at any time and usually arrive as a result of a mix of various climatic conditions occurring at the same time. Algae bloom types found in Northland are nearly always nontoxic but under certain conditions can become toxic especially to dogs.

 

The Irrigation Company infrastructure in the dam allows it to draw water from the dam at three different depths which it varies throughout the year subject to water quality. We are currently able to draw water from well below the surface water where the algae bloom thrives in the heat and light.

 

The Irrigation Company wishes to remind you the water you receive from the company at all times is non-potable. This means it is not intended for human consumption or any domestic use. It is raw untreated water from a storage reservoir that collects surface runoff water and is intended for irrigation purposes only.

 

Rigorous testing regimes are in place to ensure a safe ongoing supply of Irrigation water to your property and test results are being shared with regulatory bodies including Northland Regional Council and the Northland District Health Board.

The company web site www.keriirrigation.co.nz will be updated with any changes to the status of the water quality which is currently fit for use for its intended purpose.

If any future safety precautions are necessary, we will contact you.
