Monitoring Water Banks with Telemetrics

Longstanding droughts across South Australia are forcing farmers to rethink the moisture in the soil they once regarded as their inalienable right. Trend monitoring is an essential input to applying pesticides and fertilisers in balanced ratios. Soil moisture sensors are transmitting data to central points for onward processing on a cloud, and this is making a positive difference to agricultural output.

Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.

The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of online data and a safe place somewhere in the cloud to curate it. Sentek is in the lead in places as remote as Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.

This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily re-positioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to the end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By monitoring that need accurately, that water can be saved until later when the plant really needs it.? He goes on to add that the crop is the ultimate sensor, and that ?we should ask the plant what it needs?.

This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return. The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.

There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us. ecoVaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.

What Energy Management Software did for CDC

Chrome Deposit Corporation ? that’s CDC for short ? reconditions giant rollers used to finish steel and aluminium sheets in Portage, Indiana by applying grinding, texturing and plating methods. While management was initially surprised when the University of Delaware singled their plant out for energy assessment, this took them on a journey to bring energy consumption down despite being in an expansion phase.

Metal finishing and refinishing is an energy-intensive business where machines mainly do the work while workforces as small as 50 individuals tend them. Environmental impacts also need countering within a challenging environment of burgeoning natural gas and electricity prices.

The Consultant’s Recommendations

The University of Delaware was fortunate that Chrome Deposit Corporation had consistently measured its energy consumption since inception in 1986. This enabled it to pinpoint six strategies as having potential for technological and process improvements.

  • Insulate condensate tanks and pipes
  • Analyse flue gas air-fuel ratios
  • Lower compressed air pressures
  • Install stack dampers on boilers
  • Replace belts with pulleys and cogs
  • Fit covers on plant exhaust fans

CDC implemented only four of the six recommendations. This was because the boiler manufacturer did not recommend stack dampers, and the company was unable to afford certain process automation and controls.

Natural Gas Savings

The project team began by analysing stack gases from boilers used to heat chrome tanks and evaporate wastewater. They found the boilers were burning rich and that several joints in gas lines were leaking. Correcting these issues achieved an instant gas saving of 12% despite increased production.

Reduced Water Consumption

The team established that city water was used to cool the rectifiers. It reduced this by an astonishing 85% by implementing a closed-loop system and adding two chillers. This also helped the water company spend less on chemicals, and energy to drive pumps, purifiers and fans.

Summary of Benefits

Electricity consumption reduced by 18% in real terms, and natural gas by 35%. When these two savings are merged they represent an overall 25% energy saving. These benefits were implemented across the company?s six other plants, resulting in benefits CDC management never dreamed of when the University of Delaware approached them.

Renewable energy – Is it a common man’s cup of tea?
I came across an article on a young graduate in renewable energy engineering. The fellow was doing technical sales and marketing jobs for renewable energy products though he felt that as a graduate, he ought to be doing more than just sales. His, sentiments, I can relate with but again thinking about the field of renewable energy, how many people understand what it is, its importance/ benefits, how to acquire it, its installation, costs etc.? Renewable energy is energy generated from natural resources. The renewable energy sources include sunlight, wind, rain, tides, geothermal heat and various forms of biomass. These sources are renewable naturally and continuously replenished, therefore this energy cannot be exhausted. Renewable energy technologies range from solar power, wind power, hydroelectricity/micro hydro, biomass and bio-fuels for transportation. Back to the aspiring young professional who felt that his place in the renewable energy sector lies in doing strategies and coming up with new products-the advice fronted to him was that doing technical sales is the best job for engineers, as it helps them impact on users of their products. Sales entail interacting with customers and knowing their needs so that the product features can be enhanced to suit the customer?s needs. Now, that is brilliant and accurate advice. It is however important to take into consideration that renewable energy is not a common man?s cup of tea and right now the focus all over the world is to build green economies. To me the need for more and more people to understand the benefits, savings and cost of renewable energy cannot be overemphasised. Effort should be made to keep marketing of renewable energy products/ services simple and conversational by avoiding use of acronyms or jargon explaining about operational details. More impact can be made if a marketing rather than technical sales approach is used. Technical sales have been described as boring (can be used as a sleeping aid), tends to use extensive vocabulary, jargon and acronyms that product users cannot relate with and tends to discuss the products technical aspects as opposed to the benefits to the customer. Fun should be created out of all this by making things simple and demonstrating cost savings and benefits of renewable energy.
How To Get Started with your IT Compliance Efforts for SOX

There’s no question about it. For many of you top executives in the corporate world, all roads leading to a brighter future have to go through SOX compliance. And because the business processes that contribute to financial reporting (the crux of the Sarbanes-Oxley Act) are now highly reliant on IT systems, it is important to focus a good part of your attention there.

It is a long and arduous path to IT compliance, so if you don’t want your company to fall by the wayside due to inefficient utilisation of resources, it is important to set out with a plan on hand. What we have here are some vital information that will guide you in putting together a sound plan for SOX compliance of your company?s IT systems.

Why focus on IT systems for SOX compliance?

We’ll get to that. But first, let’s take up the specific portions of the Sarbanes-Oxley Act that affect information technology. These portions can be found in Section 302 and Section 404 of the act.

In simplified form, Section 302 grants the SEC (Securities and Exchange Commission) authority to come up with rules requiring you, CEOs and CFOs, to certify in each annual or quarterly financial report the following:

  • that you have reviewed the report;
  • that based on your knowledge, the report does not contain anything or leave out anything that would render it misleading;
  • that based on your knowledge, all financial information in the report fairly represent the financial conditions of the company;
  • that you are responsible for establishing internal controls over financial reporting; and
  • that you have assessed the effectiveness of the internal controls.

Similarly, Section 404, stated in simplified form, allows the SEC to come up with rules requiring you, CEOs and CFOs, to add an internal control report to each annual financial report stating that you are responsible for establishing internal controls over financial reporting.

You are also required to assess the effectiveness of those controls and to have a public accounting firm to attest to your assessment based upon standards adopted by the Public Company Accounting Oversight Board (PCAOB).

While there is no mention of IT systems, IT systems now play a significant role in financial reporting. Practically all of the data you need for your financial reports are stored, retrieved and processed on IT systems, so you really have to include them in your SOX compliance initiatives and establish controls on them.

Now that that’s settled, your next question could very well be: How do you know what controls to install and whether those controls are already sufficient to achieve compliance?

Finding a suitable guide for IT compliance

The two bodies responsible for setting rules and standards dealing with SOX, SEC and PCAOB, point to a well-established control framework for guidance – COSO. This framework was drafted by the Committee of Sponsoring Organisations of the Treadway Commission (COSO) and is the most widely accepted control framework in the business world.

However, while COSO is a tested and proven framework, it is more suitable for general controls. What we recommend is a widely-used control framework that aligns well with COSO but also caters to the more technical features and issues that come with IT systems.

Taking into consideration those qualifiers, we recommend COBIT. COBIT features a well thought out collection of IT-related control objectives grouped into four domains: Plan and Organise (PO), Acquire and Implement (AI), Deliver and Support (DS), and Monitor and Evaluate (ME). The document also includes maturity models, performance goals and metrics, and activity goals.

A few examples of COBIt’s detailed control objectives are:

DS4.2 – IT Continuity Plans
DS4.9 – Offsite Backup Storage
DS5.4 – User Account Management
DS5.8 – Cryptographic Key Management
DS5.10 – Network Security
DS5.11 – Exchange of Sensitive Data

By those titles alone, you can see that the framework is specifically designed for IT. But the document is quite extensive and, chances are, you won’t need all of the items detailed there. Furthermore, don’t expect COBIT to specify a control solution controls for every control objective. For example, throughout the control objective DS4 (Ensure Continuous Service), you won’t find any mention of virtualisation, which is common in any modern business continuity solution.

Basically, COBIT will tell you what you need to attain in order to achieve effective governance, management and control, but you’ll have to pick the solution best suited to reach that level of attainment.
