Seqwater's 22 October Submission / Response To
SEQWATER’S 22 OCTOBER SUBMISSION / RESPONSE TO QCA REQUEST OF 12 OCTOBER 12 October 2012 I hereby provide Seqwater with a further information request. Seqwater’s detailed responses to each item would be appreciated by COB 19 October 2012, please. Happy to discuss at any time noting the proposed due date of COB 19 October 2012 From: Colin Nicolson [mailto:[email protected]] Sent: Friday, 19 October 2012 1:10 PM To: Angus MacDonald Cc: George Passmore; Damian Scholz Subject: FW: Information Request 12 October 2012 Hello Angus Here are our responses to the above information request. QCA Question 1 - Cedar Pocket Stakeholders (Issues Arising (IA) Cedar Pocket 2012) submitted that more details were required regarding Seqwater’s proposed renewals expenditure [outlined in the NSP] on “electricity supply assets” in 2025-26 at $30,000. Please provide more details regarding this proposed expenditure. Seqwater Response to Item 1 The Assets in question are a property pole, meter box (excluding the meters), cabling and a distribution board. The renewal is scheduled based on the Seqwater “standard asset life” of 20 years for this type of equipment. It was installed in 2005 and will be 20 years old when the work is scheduled. The cost estimate is drawn from the estimated replacement costs as set out in Section 5.2.2 and Section 9 of the Irrigation Infrastructure Renewal Projections - 2013/14 to 2046/47 Report on Methodology. The renewal timing, will be reviewed on an ongoing basis so that it is only delivered when condition warrants. The scope and cost estimate will be reviewed prior to commencement of work to ensure the delivery is efficient. -

Aquifer storage and recovery (ASR) is a direct injection and subsequent withdrawal technology that is used to increase water supply storage through injection wells. Due to site-specific hydrogeological quantification and evaluation to assess ASR suitability, limited methods have been developed to identify suitability on regional scales that are also applicable at local scales. This paper presents an ASR site scoring system developed to qualitatively assess regional and local suitability of ASR using 9 scored metrics to determine total percent of ASR suitability, partitioned into hydrogeologic properties, operational considerations, and regulatory influences. The development and application of a qualitative water well suitability method was used to assess the potential groundwater response to injection, estimate suitability based on predesignated injection rates, and provide cumulative approximation of statewide and local storage prospects. The two methods allowed for rapid assessment of ASR suitability and its applicability to regional and local water management objectives at over 280 locations within 62 watersheds in Washington, USA. -

Estimation of the Base Flow Recession Constant Under Human Interference Brian F
WATER RESOURCES RESEARCH, VOL. 49, 7366–7379, doi:10.1002/wrcr.20532, 2013 Estimation of the base flow recession constant under human interference Brian F. Thomas,1 Richard M. Vogel,2 Charles N. Kroll,3 and James S. Famiglietti1,4,5 Received 28 January 2013; revised 27 August 2013; accepted 13 September 2013; published 15 November 2013. [1] The base flow recession constant, Kb, is used to characterize the interaction of groundwater and surface water systems. Estimation of Kb is critical in many studies including rainfall-runoff modeling, estimation of low flow statistics at ungaged locations, and base flow separation methods. The performance of several estimators of Kb are compared, including several new approaches which account for the impact of human withdrawals. A traditional semilog estimation approach adapted to incorporate the influence of human withdrawals was preferred over other derivative-based estimators. Human withdrawals are shown to have a significant impact on the estimation of base flow recessions, even when withdrawals are relatively small. Regional regression models are developed to relate seasonal estimates of Kb to physical, climatic, and anthropogenic characteristics of stream-aquifer systems. Among the factors considered for explaining the behavior of Kb, both drainage density and human withdrawals have significant and similar explanatory power. We document the importance of incorporating human withdrawals into models of the base flow recession response of a watershed and the systemic downward bias associated with estimates of Kb obtained without consideration of human withdrawals.

Module III - Water, Ecosystem Services, and Biodiversity
Environmental Review Guide - Water, Ecosystem Services, and Biodiversity Module III - Water, Ecosystem Services, and Biodiversity The purpose of this module is to link the Regional Environmental Review Program to the goals of the Division of Ecological and Water Resources. The Division of Ecological and Water Resources works with others to: • Protect, restore, and sustain watershed functions (land-water connections, surface water resources) • Protect, restore, and sustain biodiversity and its adaptive potential • Protect, restore, and sustain groundwater resources • Provide and support excellent outdoor recreation opportunities • Minimize the negative economic and ecological impacts of invasive species • Support sustainable natural resource economies • Help achieve other DNR core objectives • Create and maintain a learning organization that implements the division’s guiding principles The Environmental Review Program is a key component in the Department of Natural Resources’ efforts to improve Minnesota’s water, ecosystem services, and biodiversity. DNR staff members involved in evaluating the effects of land- and water-use plans and economic development projects must take an integrated, systems-based, collaborative, and community- based approach to improving the habitat base and providing technical advice on actions that have the potential to adversely affect the environment. Staff must be ever mindful of the need to sustain (1) quantities and qualities of water that will ensure that Minnesota’s people and other biota can survive and thrive in the midst of changing trends in energy, climate, and demographics; (2) levels of diversity that will provide native Minnesota species and biomes with the resilience and adaptive capacities they need to evolve and thrive in the midst of changing conditions; and (3) economically vital ecosystem services that will provide Minnesota with economic and ecological security into the future. -
