Waste Water Management

Contaminated water arises at Levenseat arises from two principal sources – the landfill and compost blocks. Contamination arises when rainfall comes into contact with waste. The principal contaminants are nutrients which can be metabolised by micro-organisms and if water with a high nutrient load were discharged into local burns the result could be an algal bloom which would cause depletion of the oxygen dissolved in the water. This in turn could result in the deaths (effectively through suffocation) of fish and other animal life. It is therefore important to remove the nutrient load from rainwater which has been in contact with waste.

This is achieved in a specialised waste water treatment plant which uses activated sludge technology. This is simply the cultivation and husbanding of a population of micro-organisms which metabolise the nutrient load in the waste water. The principal requirements of the system are that the micro-organisms are supplied with sufficient oxygen to permit the required consumption of nutrients and that temperatures are maintained in excess of around 12^o C.
