Many people have got a lot to say about WIND verses SOLAR. Most of which is uneducated, ill informed and comes from people that have a limited knowledge of Windmills.

However, they do have a commercial reason for telling you the Windmill is out dated and high maintenance. Windmills are well suited to low yielding bores and usually wear out from no maintenance and having to work beyond their capabilities.

The basic design of the Windmill has not changed in 200 years. A modern Windmill that is set up to a proper standard with regular maintenance being performed, could last 30 years, before requiring new bearings and a re-build. The column will need replacing every 10 years and the pump every 5-10 years.

Here at Midwest Groundwater we are well versed in BOTH Wind and Solar (and all types of other pumping systems) so you receive the pumping system that suits your requirements and not the system that we want to sell you.

We stock thick ProPol columns with tough, solid riser pull rods that are extremely durable and don’t wear out.

We have all the right clamps, stuffing boxes and knowledge to set your Windmill up to the correct standard.
