• • • aware of this accelerated growth and is reviewing the Comprehensive Plans submitted by each community in this region to evaluate their future wastewater collection, treatment, and infrastructure capabilities. MCES wastewater treatment facilities and interceptor systems are designed based on projected regional land -use and growth plans. Therefore, any significant changes in future land -use and development of the City will have an impact on MCES facilities. MCES INTERCEPTORS AND LIFT STATIONS SERVING LINO LAKES The City of Lino Lakes sewer system currently discharges to the MCES Interceptor system at four locations. Sewer District 2 is served by MCES Interceptor 83 -61, located in North Road on the Lino Lakes /Circle Pines boundary. Service to District 1 is provided by MCES Lift Station L69, located on Ware Road. Sub - District 3F, as well as the City of Centerville, is served by MCES Lift Station L4, and located in Centerville. The MCES Centerville Interceptor (Interceptor 76 -51), located in Cedar Street, receives the pumped discharge from Lift Station L4, as well as flow from Sewer District 3. Lino Lake's flows will be discharged to the regional system at two additional locations in the future. Sewer District 4 will be served by a White Bear Township trunk sewer, ultimately discharging to the Forest Lake interceptor. District 5 will be served by the newly constructed Lino Lakes Relief Interceptor. The locations of these facilities are shown on Figure 7 -1. The following paragraphs provide a brief description of each of the existing MCES and White Bear Township facilities. MCES Interceptor 83 -61 The existing interceptor is a gravity sewer which provides an outlet for Lino Lakes Lift Stations 2 and 4. MCES Meter Station M211 is located at the discharge end of the forcemain serving these two lift stations. A peak flow capacity of 3.6 million gallons per day (MGD) has been allocated to Lino Lakes at this connection. Interceptor 83 -61 flows west and discharges into the North Suburban Interceptor (4 -NS -523). As a result of recent development projections by Lino Lakes, Blaine, and other cities, MCES has committed to provide additional capacity at this location. The proposed Southeast Anoka County Interceptor, scheduled for 2009 completion, will provide an allocated capacity of 7.6 MGD for Lino Lakes. MCES Lift Station L -69 This lift station, located on Ware Road, was constructed in 1995 -96 to replace an earlier MCES facility, Lift Station L -53. Lift Station L -69 discharges west through a long forcemain to the North Suburban Interceptor (4 -NS -523) in the City of Shoreview. The current design capacity of Lift Station L -69 is 2760 gallons per minute (gpm) or 3.97 MGD. It can be upgraded to 2920 GPM (4.20 MGD) by changing pump impellers. MCES Meter Station M219 is located at the lift station. MCES Lift Station L -4 The service area of this lift station is limited to a small, fully - developed area of Lino Lakes (District 3F), as well as the City of Centerville. This lift station and forcemain were upgraded by MCES in 2000 to provide for the long -term needs of this service area. MCES Meter Station M210 is located at the lift station. The forcemain discharges into MCES Interceptor 76 -51 at the intersection of 21st Avenue and Cedar Street. MCES Interceptor 76 -51 (Centerville Interceptor) This interceptor is a 24 -inch gravity sewer constructed in 2000. It flows east into the City of Hugo and connects to the Forest Lake Interceptor (MSB 7029). Interceptor 76 -51 receives flow by forcemain from MCES Lift Station L -4, and also from forcemains serving Lino Lakes Lift Stations 6 and 7. MCES Meter Station M220 is located on the Lino Lakes /Hugo boundary on Cedar Street. The interceptor at the Lino Lakes boundary has a gravity capacity of 4.62 MGD, of which approximately 3.5 MGD is available to Lino Lakes. 7 -19
