It can be a challenge to decide which spending model is right when commissioning a wastewater monitoring programme
As monitoring specialists, we work with several water companies to deliver bespoke waste water monitoring projects, ongoing data analysis and site maintenance to fulfil a wide variety of operational requirements.
Commissioning a wastewater monitoring programme can be a significant investment and a long term project. It can be a challenge to decide which spending model is right.
As well as installing, maintaining and managing monitors on behalf of certain clients, we also have a number of water companies that have purchased our monitors using capital expenditure budget and then subcontracted the maintenance and management of that equipment to a third party as an operational expense.
Over the last few years, we have established a partnership with a large UK water company that has purchased a total of 150 of our MSFM S2u monitors as a capital expense to the business. The water company then chose to use their operating expenditure budget to subcontract the consequent installation, maintenance and management of those monitors across the catchment to us.
The tables below show the savings that this water company has made in relation to this capex and opex split, as opposed to running with a purely opex model. Monitoring across the catchment is continuous but the company could also choose to use the monitors intermittently for specific purposes. The last box on the table reveals the savings adjustment that the company would save if they opted to only monitor sites seasonally or do flow surveys 50% of the year, for example. So, whether operating continual or seasonal monitoring there are significant savings to be made using a capex/opex monitoring model versus a purely opex monitoring model.
|Year 1 CAPEX||150||£3,500.00||£525,000.00||£525,000.00|
|Year 1 OPEX||150||£40.00||£6,000.00||£72,000.00|
|Year 2 OPEX||150||£40.00||£6,000.00||£72,000.00|
|Year 3 OPEX||150||£40.00||£6,000.00||£72,000.00|
|Year 4 OPEX||150||£40.00||£6,000.00||£72,000.00|
|Year 5 OPEX||150||£40.00||£6,000.00||£72,000.00|
|50% OPEX adjusted for seasonal variation||£1,440,000.00|
It can be very beneficial to actually purchase and then own Detectonic monitors and related equipment outright. Key benefits include:
In relation to ongoing management of the equipment, employing a subcontractor can be a highly effective solution with numerous advantages such as:
Since working with this specific UK water company, we have made a real difference. Our expertise and insight have supported the client to save both time and money. For example, during the nine month period from January – September 2018, our data centre received 86,461 high alarms from the MSFM S2u monitors in the catchment. Following expert analysis, our professional data analysts trimmed those alarms down to just 174 reports that were forwarded to the client.
From that data 64 potential pollutions were reported with 36 being confirmed and 110 interventions (where depth is irregular but below spill level) were implements with just 60 being confirmed.
Having Detectronic as a subcontractor makes operations much more manageable for the client and allows them to direct their crews to investigate the right sites where problems are occurring thus saving valuable time AND money.
“We have been encourage to think differently about how we work and to develop a sharper focus than ever on improving customer service. The result has been a great performance that has generated outperformance payments of £88 million in our waste water service. At the same time, in relation to sewer flooding, we have made much more progress at a much faster rate than we thought possible.”download
