Prevention
The Algal bloom can be prevented in the following ways:-
1) Algae need three things for optimal growth: light, nutrients and high temperatures. Therefore, By Lowering the nutrients, light and temperature available to the blue-green algae in the water supply will help reduce algal growth. The speed at which water is flowing and mixing is important in controlling light and nutrient availability to algal cells.
2) Keeping livestock away from the farm dam or water supply.3) Avoiding run-off into water supply from fertilizers and pesticides
4) Taking some water treatment measures BEFORE a bloom starts; and if practical - changing mixing patterns or covering the dam/water supply to screen out light may help.

Approximately 250 acres of Ngawai farm earmarked for turbines drains into the Turitea catchment.
Now just add in a wind farm and stir. Really, just how can PNCC be so cavalier about our water supply ? The integrity of our water supply must have the highest priority. It should not be for sale, nor should the high value bush in the water catchment with taonga bird species be jeopardised at any price. To do so is deeply offensive to responsible and thoughtful Maori and Pakeha.

A 262 foot wind tower northwest of Bloomfield Nebraska burst into flames. Officials say three men were injured in the fire. One was sent by Life Flight to Sioux City with extensive burns.

Fire at Hancock County, Iowa, wind facility, Oct. 3, 2007 - from Arian Schuessler, Mason City Globe Gazette
Above picture : the c400 litres of oil from the gearbox can catch fire and fall to the ground while burning, setting fire to vegetation.
Search the net and you will find numerous examples of turbines on fire.
eg
Turbine fire at Ewington wind farmAccording to fire chief John Garmer, the wind turbine had a "ball of flame" on top when firefighters arrived at the scene. ...The fire was located at the six-turbine Ewington Wind Farm, the same site where a wind generator burned two months ago.

Smoke pours from the top and bottom of one of the wind turbines at the Ewington Wind Farm near the Heron Lake exit north of Interstate 90 Wednesday (Mar 26) morning. The Brewster and Okabena Fire Departments responded to the scene, but upon the advice of Suzlon Wind Energy officials, the fire was allowed to burn itself out. (Brian Korthals/Daily Globe) A short movie of a Wind Turbine on fire in Wulfshagen/Germany on May 16th, 2005. This fire is just one of many in the same location. Fire fighters can only wait helplessly on the ground and let these fires burn out. Even wind farmer John Love , who has posted a comment under the nickname of "Lofty" , admits turbines catch fire.
A portuguese turbine burns spectacularly earlier in 2008.
This is a must see
Many more here:
But wait there's more. On Browns flat there is a substation with two transformers containing 60,000 litres of oil each ( MRP documentation is confusing as it states up to 100,000 litre capacity, depending on which page you care to look at ). Browns flat is the headwaters of the Turitea catchment. Watch a transformer explode and burst into flames here. This has already happened at Te Apiti when there was a power surge. Provision is made by MRP in its plans for an oil spill with the construction of what is known as bunding ( dykes ) so they anticipate "accidents" but this type of calamity will do more than pour oil on troubled drinking water as you can see in this youtube clip. ( Note, all video clips can be full screen for better viewing )
A transformer failure that burnt for days spreading its toxic load far and wide.
Another transformer on fire. Plenty more transformer/substation fires here:
So who is willing to risk
incinerating the Tararua ranges within the city boundary, putting the environment, our water supply
and life and property at risk ?

Well no thinking person would. After all this is a university city isn't it ?
Washing turbines (with detergent)
Should add a distinctive flavour to the city's water supply.
The wind at the top of the Tararua Ranges is particularly turbulent. Look at what has happened elsewhere.
The relatively new turbine below simply folded and collapsed. Steel exposed to the elements eventually rusts and develops stress fractures. Photostream here:
Electrical energy demand likely to decrease as the world faces a severe economic contraction.

NOVEMBER 21, 2008 Surprise Drop in Power Use Delivers Jolt to Utilities
An unexpected drop in U.S. electricity consumption has utility companies worried that the trend isn't a byproduct of the economic downturn, and could reflect a permanent shift in consumption that will require sweeping change in their industry. Numbers are trickling in from several large utilities that show shrinking power use by households and businesses in pockets across the country. Utilities have long counted on sales growth of 1% to 2% annually in the U.S., and they created complex operating and expansion plans to meet the needs of a growing population. [...] The data are early and incomplete, but if the trend persists, it could ripple through companies' earnings and compel major changes in the way utilities run their businesses. Utilities are expected to invest $1.5 trillion to $2 trillion by 2030 to modernize their electric systems and meet future needs, according to an industry-funded study by the Brattle Group. However, if electricity demand is flat or even declining, utilities must either make significant adjustments to their investment plans or run the risk of building too much capacity. That could end up burdening customers and shareholders with needless expenses. To be sure, electricity use fluctuates with the economy and population trends. But what has executives stumped is that recent shifts appear larger than others seen previously, and they can't easily be explained by weather fluctuations. They have also penetrated the most stable group of consumers -- households.
The Turitea wind factory is potentially an extremely expensive white elephant.
