amongst the 9th lowest since 1980 at nearly 52% reservoir

storage.

Drought mitigation

45 Tanker Purchase

605 Water tank installations

162 Spring protection

189 Boreholes

Limited Water Resource Potential

Water is not always located near uses

Surface Water Potential Ground Water Potential

Total Runoff = 49 billion m3/year (<50% of Zambezi river)Reliable yield for use = 10,2 billion m3/year (27% of runoff)Remaining development potential = 5,4 billion m3/yrPotential re-use of return flows = 1.9 billion m3/yr

Total potential = 19 billion m3/yearUtilizable potential = 5 billion m3/yearEconomical use is less due to size & locationCurrent est use = 2-3 billion m3/year

CS 3 – Aggressive Pressure Management • To date 34 time controllers have been installed and

commissioned

• The savings are 4.4Ml/day or R8.8million/year

• The total cost for the 34 time controllers and labour was R1.7million thus ROI was 2.3months

CS 3 – Accelerated Leak Detection and Repair • Started on an accelerated program in Jan 2016

• In Msunduzi to date 1,597 km of retic has been surveyed and 1,097 leaks have been found and repaired through 1 survey

• In Vulindlela to date 1,460 km of retic has been surveyed and 1,263 leaks have been found and repaired through 3 surveys

• The theoretical savings from the leak repair is approximately

4.1 Ml/day

• The total cost was R4.99million and ROI is 7.3months

Internal Leak Repair

Completed internal leak repairs in:

Haniville – 2,808 leaks repaired

Thembalihle – 2,073 leaks repaired

Madiba Park – 1,473 leaks repaired

Cinderella Park – 4,807 leaks repaired

Total Capex Requirement: R3.689 billion

(over 5 years)

Or approximately R725.8 million/annum

Total Opex Requirement: R531.5 million

(over 5 years)

Or approximately R106.3 million per annum
