This includes an analysis of the potential the three new Distribution Businesses to exercise market power. For the purpose of this report, we have labeled these three businesses as follows: • DB North – which comprises Sunshine Coast and Moreton Bay council areas; • DB Central – comprising Brisbane, Scenic Rim, Ipswich, Somerset and Lockyer Valley council areas; • DB South – comprising Gold Coast, Logan and Redland. The QCA’s terms of reference for this task require Synergies to document prevailing and likely market conditions (including by geography and customer groups) with a particular focus on the demand and supply of water and wastewater, and other factors relevant to the potential exercise of market power by each new business. This report has been developed over a short timeframe, and has drawn heavily from publicly available information. In some cases, we have been constrained by the availability of information. It is also worth noting that some key policy issues and legislation are yet to be finalised in relation to these Distribution Businesses. SEQ WATER AND WASTEWATER DISTRIBUTION/RETAIL ACTIVITIES 14/01/2010 12:33:00 Page 6 of 205 QCA Demand and supply of water and wastewater Stocktake of current prices Existing water supply charges have the following features: • two-part tariffs are used in all areas for water supply, with many councils adopting inclining block tariffs; • residential users pay sewerage charges on a per property basis, while non- residential users pay on a different basis (usually per pedestal); • separate trade waste charges are commonly applied, and are differentiated by the volume of waste discharged, and in some instances by quality. In other cases, enterprise type is used as a proxy for volume and quality, using general categorisations; • infrastructure charges apply in relation to new development and expansions to the service footprint; • postage stamp pricing occurs across council areas for user tariffs, although some councils have retained charges based on pre-amalgamation boundaries. In contrast infrastructure charges are not set uniformly across council areas, but separate prices relate to different service areas ; and • residential water charges are often set at a discount to commercial and industrial users, and sewerage charges for some community and other organisations are often heavily discounted. The tables below describe the residential tariffs against the number of discrete service areas.

Notes: Lockyer Valley Regional Council, Logan City Council and Moreton Bay Regional Council charge different access charges for different areas, which largely relate to pre-amalgamation boundaries. However, the same consumption charges. In many cases, access charges also apply to vacant land or unconnected property. Supply zones include those connected to bulk transport infrastructure, as well as remote supply areas. Source: Synergies, Cardno, QCA information and publicly available Council information.

Charges in Redland refer to ‘sewer units’. This would appear to have the effect of charging residential customers on a per property basis, and commercial users on a per pedestal basis, however this is not clear from the published information.

The draft guideline published by the Department of Infrastructure and Planning1 suggests that infrastructure charges reflect the new average cost of a discrete service area, after future augmentation and incorporating demand growth (in NPV terms). These charges vary within council areas and between councils. These charges are levied on developers, rather than water users, to recover the costs associated with ‘trunk’ infrastructure identified in a PIP and Infrastructure Charges Schedule (ICS). Trunk infrastructure relates to common infrastructure upstream of the development. There are a number of notable distinctions between infrastructure charges and user tariffs in SEQ: 1 Department of Infrastructure and Planning. IPA Infrastructure Guideline 2/08 – Infrastructure charges schedule. Working draft, December (2008). p18 SEQ WATER AND WASTEWATER DISTRIBUTION/RETAIL ACTIVITIES 14/01/2010 12:33:00 Page 9 of 205 QCA • infrastructure charges are typically set on a catchment of service area basis, whereas user tariffs are set across entire council boundaries encompassing a number of different service areas; • infrastructure charges are payable by developers, whereas user tariffs are paid by users;2 • infrastructure charges relate to capital costs, whereas user tariffs relate to capital and operating costs; and • infrastructure charges are set based on the replacement cost of the existing network, yet user tariffs are likely to be set using a different asset valuation.3 It is therefore difficult to reconcile any relationship between the two sets of charges, although they are both clearly dealing with existing assets. Historic and projected volumes Residential water use accounts for approximately 70% of total demand. Among non- residential use (including commercial, industrial and government sectors), 58% of use is from larger (>10MLpa) water users. The QWC has forecast the following growth in water use, incorporating significant reductions in water use from permanent conservation measures. 2 Although it is arguable that infrastructure charges are incorporated into the value of the users land. 3 For example, DORC or another value set
