Preliminary Design Report City of Chanhassen A-CHAHN0502.00 Page ' January 10, 2005 I ' Preliminary Design Report IEast Water Treatment Plant Prepared for City of Chanhassen 1.0 Background The City of Chanhassen provides municipal water to its residents from eight ' wells. The raw water exceeds the recommended levels for both iron and manganese and the arsenic levels are approaching the Maximum Contaminant Level (MCL) of 10 parts per billion (ppb) in Well Nos. 5 and 6. Limited sequestering treatment is provided with the addition of chlorine at the well houses. Fluoride is also added at the well houses as required by the State of Minnesota to prevent tooth decay. The average iron and manganese levels in Well Nos. 2, 5 and 6 are 0.8 parts per million (ppm) and 0.3 ppm, respectively. This is about 3 times the iron standard (0.3 ppm) and about 7 times the manganese standard (0.05 ppm). These levels are too high for effective sequestering treatment. Well Nos. 5 and 6 also have arsenic present at levels approaching the MCL. Absorption of arsenic into the iron floc and subsequent filtration is expected to reduce the arsenic levels by about 80% in the water treatment plant's (WTP) finished water. Thus, the City desires to provide improved water quality through the construction of a new WTP. It is anticipated a minimum of three to four new wells will be needed in the future to provide additional supply capacity that will be treated at the new WTP. In preparation for the present WTP design, the following studies have been performed: ' 1. Pilot Report for the Removal of Iron, Manganese and Arsenic, May 17, 2004. The pilot plant study confirmed the effectiveness of the proposed treatment. 2. Distribution System Capacity Study, May 20, 2004. This computer model study confirmed the existing distribution system is adequate to handle the output from a new 6,000 gallon per minute (gpm) WTP ' located at the Ready Mix Site. 3. Lotus Lake Well Siting Study, May 20, 2004. This study confirmed the ' glacial drift and Prairie du Chien -Jordan aquifers could each provide one new 1,000 gpm (max. rate) well at both the WTP Ready Mix Site and the South Lotus Lake Park Site. 1 A-CHAHN0502.00 ' Page 1 n Lt✓ 4. Preliminary Investigation Report, Lotus Lake Water Treatment Plant, May 24, 2004. This report and subsequent review with the Minnesota Department of Health confirmed the Ready Mix Site A to be the most suitable for a new WTP. 5. Security system will include consideration of potential future homeland defense security requirements and have a high level of automation. This ' item will be addressed in more detail at the 60% review stage. 2.0 Discussion ' SEH received City Council approval to provide engineering services for a new WTP on October 25, 2004. An initial kick-off meeting was held on November 4, 2004 followed by a complete design team kick-off meeting on December 9, 2004. Preliminary design commenced for a 6,000 gpm iron, manganese and arsenic removal WTP at the Ready Mix Site (Site A). The site is located between Highway 5 and the Twin Cities and Western Railroad and just west of the intersection of Highway 5 (Arboretum Boulevard) and Chanhassen Road. The WTP will have the following features: ' ■ Water Treatment: — In -line pressure aeration. — Chlorine and potassium permanganate addition. — Gravity filtration using green sand and anthracite media. — Fluoride addition for prevention of tooth decay (state requirement). ' — Orthophosphate addition as a corrosion inhibitor. ■ The WTP below -grade components and the filter cells will be constructed with cast -in- place reinforced concrete. ■ A finished water clearwell pumping chamber will be provided below the WTP operating floor. ■ The WTP above -grade components will be constructed with brick and block. ■ The WTP roof will be a blend of sloped standing seam metal roofs and ' flat roofs with parapet perimeter walls. ■ A buried Filter Backwash Tank will be constructed adjacent to the WTP. It will also be constructed of poured -in -place concrete and provide for the recycling of 90% water used in the filter backwash process. ' ■ The WTP will include a control room, laboratory, meeting room, break room and a uni-sex toilet, in addition to the basic treatment and pumping facilities. ■ A standby power generator will be provided to enable the WTP to ' operate when the local electric power grid is inoperative. ■ The WTP operation will be tied into the City's SCADA system and be designed for automatic un-manned operation. Preliminary Design Report A-CHAHN0502.00 City of Chanhassen Page 2 I ' ■ An emergency overflow system to prevent any damage due to equipment malfunction or operator error. The local stormwater system must ' accommodate this flow. ■ A Security system will include consideration of potential future homeland defense security requirements. This item will be studied at the ' 60% design review. The following items are submitted for the preliminary design review or will be available at the work session for review: 1. Site Plan. 2. Floor Plan. 3. Typical WTP Cross Section. 4. Architectural Elevation. 5.
