Water Management

EVAPORATION Control / Dam and Channel Covers

Evaporation occurs through wind and heat – a protective canopy will reduce both these factors and hence dramatically reduce water lost through evaporation.

Between 2002 and 2007, NetPro Pty Ltd was involved with a research project coordinated by the NCEA (National Centre for Engineering in Agriculture) for the development of technology to control evaporation from water storages. (Tech. Ref. **5)

From this research our most popular dam cover structure was developed, The NetPro Evaporation canopy uses a combination of specially designed high-tensile steel cable, terminations and a modified knitted high-density shade-cloth cover.

The Benefits Of A Suspended Canopy System:

Please Note: Some construction constraints may be experienced due to shape and depth of water storages.

The CSIRO has, in a separate study, looked at "The Benefits of Shade-Cloth Covers for Potable Water Storages". (Tech. Ref. **6), the results of which were published in February 2007 in a report under that title. While the NCEA study was more concerned with evaporation control, cost and durability, the CSIRO report prioritised water quality.

CHANNEL COVERS

Cover any width and length channel, using similar implementation approach to canopy cover solution

EVAPOTRANSPIRATION

The term describing water loss from plants through emission of water vapour via the leaves by transpiration – can be a major form of stress for plants.

MICROCLIMATE ADJUSTMENT

Optimal crop production is a reality with protective netting and shade-houses. On a broad-acre trial in the Griffith area, Rural Press reported in 2007 that up to 38% less water was required for the crops covered by a netted structure.

A Growcom “Water for Profit” trial reported a significant reduction in water usage under conventional “hail-netting”, due to a 20% reduction of plant evapotranspiration averaged over a 2-month period on the Granite Belt in Queensland in late Summer / Autumn.

Success Stories View all

As major investors in the Australian horticulture industry, Rewards Group Ltd needs to ensure maximized returns on all funds invested, particularly in orchard infrastructure. Accordingly, our choice of contractors is critical to the final success of any project.

Bill Hatton - Rewards Group Ltd.

We currently have 250 acres of net – about 80% of our orchard area. Without the protective canopy, we wouldn’t be able to supply our market requirements. Quality is important to us and we wouldn’t be able to meet the specifications of our customers without net.

Dino Rizzato - I&L Rizzato & Sons t/a Moonlight Orchards

We particularly liked the product offered by NetPro – high quality was our main criteria. The option of wooden posts was also an important feature because of the highly-corrosive conditions in the feedlot environment. We were able to work through the construction plan and the materials options during the quoting process.

Kevin Roberts - Sandalwood Feedlot Pty Ltd

We chose NetPro to construct our protective canopies, as we know NetPro have been around for some time, we know their work and there are plenty of examples of their work around – we like the consistency of standard. In addition, NetPro are recognized by the Finance bodies, and it is much easier to get finance for a structure.

I think it has made all the difference to the quality of our product – it has saved us from bird attack and from hail damage." Since 2001, Robert Channon Wines have won 23 trophies, 17 gold medals, 26 silver and 55 bronze medals.

Mr Robert Channon - Robert Channon Wines

We live in North Queensland and have a nine metre pool. We needed to replace the pool cover but most local businesses we contacted wanted to replace it with a shade sail and the one quote we received to fabricate a new cover to our design seemed exceedingly high.

Owen & Diane Cheetham - Townsville

In 2003, Golden Valley Orchards were offered the opportunity to work with the NCEA (National Centre for Engineering in Agriculture) and NetPro Pty Ltd on a research project evaluating the effectiveness of (amongst others) NetPro's dam-covers.

Renato Andreatta - Granite Belt

"I think it has made all the difference to the quality of our product – it has saved us from bird attack and from hail damage." To date, Robert Channon Wines have won 23 trophies, 17 gold medals, 26 silver and 55 bronze medals since 2001."

ROBERT CHANNON, OWNER ROBERT CHANNON WINES

Initially the idea of the net canopy over the landfill was discussed with Netpro as they are a local company and at the time Netpro was considering advancing into this area (protection of landfills). Netpro assisted Council with a very reasonable price which allowed the project to proceed.
