A Wastewater . Master Plan is a comprehensive planning document that serves as a guide for decision-making and future improvements related to the City's wastewater collection, treatment, and disposal � facilities. This proposal is to prepare the Wastewater Master Plan in accordance with required content as described in your Request for Proposals, with some additional features we believe will ■ add value to the Plan. . Our firm has enjoyed a professional working relationship with the City of Scandia since 1988 and currently serves as the City's designated planner. The Wastewater Master Plan is a continuation � of those professional planning services. We understand that Scandia is a unique community and have prepared a project approach to the Master Plan based on that uniqueness. ■ We emphasize three benefits TKDA will provide the City of Scandia in preparing the Master Plan. � One, our team specializes in small municipal wastewafersystems in Minnesota. Our � experience relates to the specific needs of your Master Plan and the particular needs of systems serving a limited number of customers. We understand that you face financial challenges that � differ from large communities. Last year we addressed these and other challenges in a similar study for the City of Marine on St. Croix, a neighboring community whose wastewater system � includes on-land disposal of treated effluent. � Two, the emphasis of our project approach is on wastewater managemenf. We seek to resolve r wastewater issues by using management tools such as user charge systems, sewer use ordinances, special user agreements, and tasks related to asset management and operation and i maintenance optimization. The goal of our approach is to extend the life of your system without necessarily constructing costly improvements. � And three, we emphasize communication in the preparation and delivery of planning documents. � Just as with other planning work we have done for the City, we want you to understand and feel confident with the recommendations of the Master Plan. The Master Plan will meet your needs by � being implementable. r i An Employee Owned Company Promoting Affirmative Action and Equal Opportunity � � � � � � � � � � � � � � � � � � � � , � � � � � i ■ ■ ■ ■ a ■ � � Ms. Anne Hurlburt City of Scandia � Wastewater Master Plan February 25, 2011 � Page 2 � ■ I will manage the Master Plan project, conduct the required analyses, and serve as the City's main contact to the project.

As the principal engineer of the Marine on St. Croix Study I will incorporate procedures that were successfully applied to that study. My responsibility will be to prepare the Master Plan in � accordance with your expectations that it be accurate, clear, and impiementable. � If you have any questions about this proposal, do not hesitate to call me at (651) 292-4574 or contact me at ted.field(a�tkda.com. � � Sincerely, a . . �� _ _ • �-� � Ted K.

Ways to maximize the remaining li�`e of the system � The Marine on St. Croix system con:�ists of individual on-site septic tanks followed by a community drainfield, � commonly known as a STEP system (septic tank effluent pumping), that was installed in 1986. The system's rated capacity is 50,000 gallons per day (gpd), with current flows varying between 20,000 and 30,000 gpd. The Report � concluded that the drainfield site ha�; space for either an expansion or replacement system in the future. The merits of the two options were presented in the Report. � Based on historical flow data and otrier information, the evaluation concluded that the City could expect the � current system to last at least anothE;r 13 years, or until 2023, without the need to expand or replace. The study also advised that the remaining life could be extended 8 years or longer if remedial improvements are made to the ! system to increase its capacity or recjuce the amount of I/I entering the system. Also addressed was the issue of adding customers to the system and their impact on capacity and expected service life. � The cost of a complete drainfield replacement with capacity for future flows was estimated to be$950,000. This t estimate was to be used for future budgeting purposes. The Wastewater Evaluation Report was delivered within 2 months after the City authorized the work. Another feature of the evaluation was the development of a standard � specification for effluent pumps to facilitate pump operation and maintenance and the stocking of spare pump parts. � � � � �� * a East Bethel Water Reclamation � � Facility East Bethel, MN r � - : a � .n. � � ,,�. _ � � v � � - � � In 2010, TKDA was hired by the Metropolitan Council .. _ _ Environmental Services (MCES) to design a wastewater � � � ... treatment facility for the City of East Bethel, a growing community in Anoka County north of the Twin Cities. � i- y;` � , , The project will be the largest municipal treatment � , '° , ` ;� 1, ' �. system in Minnesota discharging treated effluent into �. -�. , . �� "�!"Y,ir � � a sub-surface drainfield and recharging underground r ��-� w = = • � '»�..L :�.: � water supplies.
