WASTE MANAGEMENT

OBJECTIVES

  • To recycle all the waste that can be recycled
  • To continuously work on changing mind-sets and behaviour to achieve this
  • To reach out to the broader community to further our goals

PROCEDURE

  • Recycling bins in every classroom, office and stations at key points around the school
  • “Recycling Village” established
  • Environmental Club representatives empty the bins around the school on Friday afternoon
  • The “Recycling Village” is emptied out by Wildlands every Tuesday.
  • Kitchen waste is sorted, recycled where possible, and food waste is collected by a local farmer.
  • Garden waste is composted or taken to the local municipality dump site.

WASTE INITIATIVES:

To continuously encourage and remind the St Anne’s community to sort their waste and place it in the correct recycling bin. Inter-house recycling competitions have also been implemented.

WATER MANAGEMENT

Where do we get our water from, and how is it managed?

  • Water is pumped from two boreholes situated in the lower end of the property, upstream of the wetland area.
  • The water pumped is sufficient to meet the daily water requirements.
  • Chlorine is added to the water in the main reservoir as a disinfectant.
  • From the main reservoir, water is pumped directly into the school reticulation system using an energy efficiency pump controller.
  • An SMS based alarm system has been fitted to both reservoirs in order to alert staff of any impending overflow situations, thus reducing the risk of wastage.

What initiatives have we put in place to reduce water usage?

  • Energy saving shower heads have been installed that restrict the water flow to 9 litres per minute versus standard shower heads which use between 15 and 20 litres per minute.
  • Bathrooms have been revamped and low usage toilet cisterns have been installed.
  • An SMS based system reads our water meters so that daily consumption readings can be taken automatically. This ensures that we are able to monitor our consumption and detect anomalies early.
  • An external laboratory carries out monthly analytical tests and submits a report of the micro-biological results. This is a legal requirement as part of the Water Services Act and is undertaken by an approved laboratory.

How do we handle our Waste Water (Sewerage)?

  • We have our own Activated Sludge type sewerage treatment plant.
  • Daily quality checks are done and the relevant readings are recorded in the site register.
  • The plant is inspected three times a day and routine tasks are performed as per the operating manual.
  • An external laboratory carries out monthly analytical tests and submits a report of the micro-biological results.

POWER MANAGEMENT

What is our current electricity usage?

  • We currently monitor our energy usage with the help of a cellphone based technology. This allows us to view live energy consumption data.
  • We are able to isolate areas consuming the most energy, thus giving us a starting point for energy reduction projects.
  • The system has enabled us to identify our peak periods and this allows us to re-arrange some of our operations in order to reduce these peaks.

What initiatives have we put in place to reduce electricity usage?

  • Heat Pump units are fitted to all our water heating installations
  • Energy saving shower heads have been installed
  • Insulation of hot water piping in order to reduce heat loss.

How much have we reduced electricity usage through these initiatives?

We have seen an overall reduction of 23% over the past few years.
