Making wastewater count

Treatment of wastewater makes it good for drinking

Wastewater is apparently the least desired type of water in the world. When we are thirsty, we often opt for still or sparkling water. For our farmlands and gardens, we breathe a sigh of relief with the sight of rainwater. Rainwater is scientifically understood to be beneficial to the growth of these flowers and plants.   While our tap water, still and sparkling bottled water is safe for drinking, rainwater with its soft attributes- presence of nitrogen, absence of chlorine and hard water minerals, is believed to be more appropriate for outdoor watering.  This is akin to Johan Cruyff’s thought which goes thus: “Every disadvantage has its advantage.” Rainwater could be somewhat disadvantageous for drinking when it is not properly filtered but is beneficial to plants in its most natural state.

It is now important to get back to the much-maligned wastewater. We keep a manageable distance in the sight of wastewater from a sewer overflow. The livelihoods of fishermen are grossly affected in the event of storm water runoff, due to dangerous pollutants that affect the livelihood of fishes and other aquatic life. Wastewater is believed to be adversely affected in quality by anthropogenic elements- simply put, pollution emissions as a result of human activities.


Knowing how obnoxious and unhealthy waste water is, how then can we make it count?  This is the question that begs for more answers.  We will approach this answer by revisiting a thought by Wayne Dyer, which goes thus: “Transformation literally means going beyond your form.”  Wastewater in its current form is displeasing and fails to count in our daily priorities. As it gets transformed and changes to a more purified state, we take it more seriously as we fetch from our tap or purchase from the grocery stores.

Wastewater transformed for drinking is synonymous to gold refined for fashion. The process of transforming or treating wastewater takes place at three different levels. The primary level is also known as the mechanical treatment, which helps in the removal of gross and floating solids from raw sewage. The next level is known as the secondary or biological treatment tier, which sees the removal of dissolved organic matter. Tertiary is the final stage and witnesses a removal of about 99% of impurities from sewage, which leads to the production of drinking water.

Waste water has the potential to be a refreshing drinking water. At Hydro Cleansing, our aim is to be part of the change process. It’s a change process that sees the creation of something good from something perceived as bad. We specialise in emptying your sewer and channelling this wastewater along the lines of transformation.

Kingston Fatberg

Over the past few weeks you can’t have escaped the press coverage that has surrounded the now infamous fatberg lurking under Kingston, southwest London. If you have then you’ve most probably been hiding down a sewer yourself! The supposed ‘bus sized’ fatberg could have potentially pushed raw sewage up into homes and onto the streets of Kingston but how has this been allowed to happen?

Weighing in at a reported 15 tonnes this mount of congealed fat, oil and grease mixed with other revolting waste products was brought to the attention of local water authorities after local residents complained about having difficulty flushing their toilets. But how can its weight have been calculated when it hadn’t even been removed.  Surely the actual weight of a fatberg cannot be decided properly until the job is complete?

Subject to contrary belief we believe the fatberg is yet to be fully removed and in fact weighs a lot less than 15 tonne. Without the necessary equipment and technical know-how the removal of this particular fatberg will take a lot longer than expected, all the while still causing problems for local residents. Time and investment are an essential requirement when it comes to preparing yourself to undertake such specialist works. Megatron is a textbook example of this.

Megatron was commissioned back in 2008 when Hydro Cleansing invested over half a million pounds engineering this wastewater monster to our own personal spec. From our perspective we had three main objectives we wanted to achieve:

  1. Increase the capability of a single onsite vehicle, which also reduces our environmental impact and carbon footprint
  2. Cope with the inevitable migration from planned to reactive works
  3. Time efficiency, reducing job turnaround times

With Megatron now undertaking works that were previously relinquished, and with more units in the pipeline, Hydro Cleansing are more than capable of embarking on any major works or specialist projects all the while alleviating any concerns that the job is to big or can’t be done at all.
