background on tcta
Background on TCTA

TCTA is a Special Purpose Vehicle

Responds to directives/mandates from the Minister of Water and Environmental Affairs to fund and implement bulk raw water infrastructure on behalf of DWA

Board is appointed by Minister of Water and Environmental Affairs

Established under the Water Act

Schedule 2 Public Entity w.r.t. PFMA

Limited recourse approach

No balance sheet

Break-even of revenue to costs over a specified period

Fully debt funded – no equity

Ring-fenced projects – tariffs related to a specific project – no cross-application of revenue

Non profit-taking organisation

Recover actual costs – overhead and capex, no profit/loss or reserves

Risk averse approach – risk is transferred to parties best suited to manage it

Revenue stream terminates once debt is repaid on a project

Tariffs are TCTA’s main source of revenue

water supply value chain

Water Boards

Distribution of water

interested and affected stakeholders
Interested and affected stakeholders
  • TCTA
    • Tariffs will generate sufficient revenue streams to meet contractual obligations and sustain TCTA
    • Correct tariff set so as not to misinform stakeholders
  • Banks and bondholders
    • Repayment of loan obligations within contract terms
  • SARB
    • Support inflation targeting
  • National Treasury
    • Protection of sovereign against unnecessary risk - Bankable project
    • Relieve government from financing commercial infrastructure from the fiscus
    • Ensure affordability of tariffs to users
    • Responsible utilisation of state guarantees
  • DWA
    • Inflationary increases in raw water as start of water chain input cost
      • Affordability and predictability to end-users
      • Uncomplicated annual tariff consultations – inflationary increases
    • Water demand management incentive (pay on actual use)
    • No cross subsidisation between projects – transparency of costs
    • Compliance with Water Pricing Strategy
interested and affected stakeholders1
Interested and affected stakeholders
    • Inflationary increases
    • Fair tariff structures
  • Municipalities
    • Limited to inflationary increases, including raw water components
      • DWA expects TCTA to support this objective
      • Municipality and Council pressure to keep increases low
  • Water sector and end users
    • Tariff stability and predictability
    • Affordable water
    • Inflationary increases acceptable
    • No cross subsidisation between projects – transparency of costs
  • Fitch Ratings
    • Credit rating of all TCTA projects except LHWP
tariff principles
Tariff Principles
  • Tariff categories for off-budget schemes:
    • Capital Unit Charges (to repay debt)
    • Bulk Operating and Royalties Charge (to repay royalties and bulk O&M)
    • Water Use Charges (statutory charges as per pricing strategy)
    • Operations and Maintenance Charges (State schemes portion)
    • Betterment and Refurbishment Charges (if applicable)
  • Input data supplied to TCTA as follows:
    • BER:
      • long-term economic forecasts (inflation, real interest rates)
    • DWA:
      • water demand forecasts (high and low scenarios)
      • system yields
      • future schemes timing and projected costs


tariff principles cont
Tariff Principles (cont.…)

TCTA recovers the following tariffs:

Raw water tariff as capital unit charge to repay debt

Bulk Operating and Royalties charge to cover royalties and bulk O&M

Full cost recovery from water sold to end-users or take-or-pay where required

Based on water sold out of system and not on water delivered into the system from the specific project

supports water demand management initiatives

reduces demand risk

Constant tariff in real terms which increases with:

CPI annually

Triggers as per the Income Agreement

Repayment of debt within reasonable period (eg 20 years)

Affordable structure to the end-user

Tariff setting takes account of tariff, funding and risk management principles in combined approach

other considerations
Other considerations

National Water Pricing Strategy

Administered prices – inflation targeting

Stakeholder consultation outcomes

Affordability to end-users

phasing-in of large adjustments

allowance for capitalisation of interest in early years

tariff setting balancing effect
Tariff Setting Balancing Effect






  • Considerations to support debt management:
  • +20 year repayment period
  • Peak of debt in relation to value of asset (limit interest capitalisation)
  • Risk transfer to end-user – trigger adjustments if input assumptions change
  • Water sector debt profile – debt overlap with future schemes
  • Interest rates mostly fixed
  • Utilisation of explicit Government guarantees and impact on National Treasury
  • Considerations to support end user affordability:
  • Under recovering in early years
  • End-user pays on actual use if bankable
  • Constant tariff in real terms approach – CPI targeting
  • Phasing-in of large tariff adjustments over 2-3 years
  • Take account of future augmentation – future affordability
  • No reserves built into tariffs
  • Actual cost transfer – TCTA not profit taking

Tariff Setting Process – May to August

Sensitivity Analysis & Stress Testing


Planning process


  • Rand Water Services Forum
  • Other Major stakeholder forums
  • Input data

Demand, system yield, economic fundamentals, cost and timing of future augmentation schemes

  • Long-term projections

DWA compiles long-term demand projections based on coordinated approach with DWA – various departments involved, Water Boards’ Planning and Budgeting departments, Large industrial users, Muni’s etc.

  • Sensitivity Analysis
  • Inflation, real interest rate, timing of future augmentation schemes and repayment periods
  • Stress Testing

Lower inflation, changes in yield of system, higher real interest rate, zero growth in demand etc

  • Stakeholder validation

Demand projections, system yield, economic fundamentals, cost and timing of future augmentation schemes

  • Consultation with National Treasury and SARB

On administered prices

  • Consultation with DWA management structure

Scope of service

  • The annual audits will include, inter alia,
  • Correct capture of assumptions, i.e.:
    • General input assumptions; demand projections, CPI, real interest rates, admin costs, funding requirements and LT cost plans;
    • Funding input; calcs relating to loans, bonds, interest, fees, capital requirements, capi, CPI uplift on CPI-linked instruments;
    • Loans on models correspond with loan agreements
  • Confirm the accuracy of the following outputs:
    • Net debt curve
    • Tariff
    • Gross borrowings
    • Graphs, etc.

Scope of service (cont.…)

  • Assess the accuracy of the financial models:
    • Initial audits only – review the logic and accuracy of computations;
    • For subsequent audits – map out changes in logic and construction of the model from the previous audited version, and review where changes have been detected;
  • Deliver an initial report of findings and recommendations relating to the accuracy, integrity, highlighting issue for TCTA’s attention;
  • Review changes made by TCTA following initial report;
  • Deliver final opinion letter (report) by the 15th of September, annually;
  • First year only, report to be delivered by 31 March 2014.
