4 Rationale for tariff increment Rand Water has followed a consistent rationale for increasing its tariff over the years. This rationale has been based on assessing the Rand Water internal rate of inflation. This is a projection of the expected increase in total costs. A breakdown of the total costs and their overall expected rate of price increase is then proposed as the proposed tariff increment.

5 Raw Water Tariff Increment In previous years, lower tariff increments have been followed by high tariff increments, as shown above. This makes the exercise of multi-year tariffs difficult to achieve.

6 Consumer Price Index (CPI) Adjustment - Phase 1 This covers the outstanding debt of Phase 1 of the Lesotho Highlands Water Project (LHWP). This increased by 4.60 per cent (8.95 cents / m 3 ). This increase coincides with the May 2011 CPI figure, as formulated by the TCTA model. Phase 2 – Lesotho Highlands Water Project (LHWP) This relates to the second phase of the LHWP. Therefore, the tariff overlaps the two phases. Trans – Caledonia Tunnel Authority (TCTA)

9 Energy Costs Rand Water has to take into consideration tariff increments of 24.8 per cent : per cent: per cent :2013 This is a huge imposition on Rand Water input costs which many customers struggle to understand. Rand Water receives its energy from Eskom as well as three other municipalities. Therefore Rand Water still has to pay an additional energy tariff increment from the three municipalities over and above the 26.1 per cent energy tariff increment. A historical trend analysis shows that these municipalities have increased an additional 12.5 per cent over the tariff imposed by Eskom. In addition, this is an increment to an already higher tariff.

11 Chemical Costs An important component of chemical costs is that some of the chemicals are imported. Therefore, it is important to take note of the current weakening of the Rand. Taking into consideration the rising CPI, chemical costs are expected to increase by 12.5 per cent.

Revenue increased driven by a 4% increase in volumes compared to 2009/10. Normal growth in volumes of 2% projected going forward. 13 for the year ended 30 June Actual 2009/10 Budget 2010/11 Budget 2011/12 Income statement Revenue Cost of Sales (2 435)(2 702)(3 031) Gross Profit Financial Performance
