Town Administrator/Engineer 301 Walnut Windsor, Colorado 80550 RE: Westwood Village Lift Station Design Engineering Report Dear Dennis, This is in regard to the proposed Westwood Village project to be developed by Everitt Co., and in particular to a proposed sanitary sewer lift station that will be incorporated into final design. A Colorado Department of Health Application for Site Approval is attached. This engineering report is intended to clarify the design concepts for the proposed lift station. Westwood Village is located in the North half of Section 20, Township 6 North, Range 67 West of the 6th P.M., Town of Windsor, Weld County, Colorado. The site contains approximately 52 acres, and will consist of 145 single family residential lots, approximately 4.4 acres for future townhome development, and approximately 18.32 acres for future commercial development. The site is also hounded on the north by Main Street (Colorado State Highway No. 392). The site is located within the 100 year and 500 year floodplain boundaries of the Cache La Poudre river, as defined by FEMA. Total contribution to the proposed lift station is anticipated to be 145 single family detached residential lots. The proposed commercial parcel and the townhome parcel will be able to gravity drain to a proposed 18" sewer extension through Westwood Village. Maximum anticipated flows to the lift station were calculated with 40 townhome units also contributing to the lift station. Design flows were based on the following criteria. Average flow used was 100 gallons per capita per day. Each home was assumed to house 3 people. A peaking factor of 4 times the average flow was used. This calculated out to approximately 1.0 gallon per minute for each lot (this also included an additional 0 1 gallons per minute for infiltration). For 145 single family detached residential lots plus an additional capacity for 40 townhome units, the design flows for this lift station have been estimated at 200 galloas per minute. There will not be any additional lots connected to this sewer and through this lift station. These flows will remain consistent as the lots are built out through the next 20 years. 951450 From this lift station, flows will be directed to the east by an existing gravity sanitary sewer through the Riverbend at Westwood Subdivision. Treatment will be by the City of Windsor Wastewater treatment facility located at 30502 State Highway 257. Per Dennis Wagner, the ultimate capacity of their facility is 1.5 MGD. Peak flows from this lift station will be 0.22 MGD, or approximately 15% of the plant capacity. Organic capacity of the existing plant was also estimated at 1980 lbs per day. A cost estimate for the proposed lift station is attached. Total initial cost has been approximated at $60,000. Estimated yearly maintenance and operating costs are estimated to be approximately $2000. Life of a typical lift station could be approximated at 20 years for the pumps, and telemetry systems, and 50 years for the wet well, piping, and surface improvements. The system being proposed will be a recessed wet well mounted lift station with duplex recessed impeller type non -clog pumps. Pumps will be 2 - 42B2 Smith & Loveless 1170 rpm pumps rated at 5 motor horsepower, 2 brake horsepower. Minimum pump efficiency at dynamic head of 24.41 feet is 62%. Attached is the technical specifications for a package system sold by Smith and Loveless. A 5' diameter concrete wet well will be used. The system will be powered by three phase electric. A pad mounted natural gas backup generator will be included. The site will be enclosed by a 6' high chain link fence with a locked access gate. The system will comply with all of the City of Windsor design requirements for Sewage Pump Station Standards. Safety features of the proposed lift station include a backup generator in case of a power outage. An 1' high earth berm will be constructed around the perimeter of the lift station site (approximately 25' x 20', which will provide an additional 3000 gallon storage capacity. In the event this is overtopped, the site will be graded such that any additional overflows will be directed towards a detention pond, and not to surrounding properties. Telemetric instrumentation shall include the following: High level wet well Generator Fail Station Flooding Priming system fail Microtel automatic telephone dialer 951450 Thank you for your time and consideration.

SEWAGE PUMPS The pumps shall be 4" vertical, recessed impeller type with impeller mounted completely out -of the flow path between the pump inlet and discharge connection so that solids pumped are not required to flow through the impeller. All internal clearances shall be equal to the discharge diameter so that all material which will pass through the discharge will pass through the pump. The pumps shall be of heavy cast iron construction, especially designed for the use of mechanical seals and vacuum priming. In order to minimize seal wear caused by lineal movement of the shaft, the shaft bearing nearest the pump impeller shall be locked in place so that end play is limited to the clearance -within the bearing. To minimize seal wear resulting from shaft deflection caused by the radial thrust of the pump, the shaft from the top of the impeller to the lower bearing supporting the impeller shall have a minimum diameter of 1-7/8". The dimension from the lowest bearing to the top of the impeller hub shall not exceed 6". The bearing nearest the impeller shall be designed for the combined thrust and radial load. The upper bearing shall be free to move lineally with the thermal expansion of the shaft -and shall carry only radial loads. The shaft shall be solid stainless steel through the pump and bottom bearing to eliminate corrosion within the pump or the mechanical seal. Removable shaft sleeves will not be acceptable if the shaft under the sleeves does n.>t meet the specified minimum diameter. The punip impeller shall produce -a turbine -like flow pattern within the casing, generating flow. It shall be made of close - grained cast iron and shall he balanced. The impeller shall be keyed with a stainless steel key and secured to the motor shaft by a stainless steel cap screw equipped with a Nylock-or other suitable self-locking device. The impeller shall not be screwed or pinned to the motor pump shaft and shall be readily remov- able without the use of special tools. To prevent the build-up of stringy materials, grit and other foreign particles around the pump shaft, all impellers -less than full diameter shall be V inn tied with the back shroud remaining full diameter so that dust! i,,in111111111 deal aura nom sternal to casing is nlaintalned. `Both the end rl the draft and the bore of the impeller shall be toppled In pet nit rstsy r entoval of the -impeller from the shah.

Priming from high pressure connexions which allow solids to enter and clog the printing system, will not be acceptable. The priming bowl shall be transparent to enable the operator to monitor the priming level. The pump shall he at ranged so that the rotating element can' easily be removed from the casing without disconnecting the electrical wiring or disassembling the motor, impeller, back - head or seal, so that any foreign object may be removed from the pump or suction line. The pump shaft shall be sealed against leakage by a single mechanical seal constructed so as to be automatically drained and primed each time the pump is drained and primed. Water -which lubricates the mechanical seal shall be automatically drained from around the seal if the pump loses prime, in order to allow both the -pump and the seal to be drained, thereby preventing freezing .and breakage of the seal during power outages in sub -freezing temperatures. The seal shall be of carbon and ceramic materials with the ceramic mating surface lapped to a flatness tolerance of one light band. The rotating ceramic shall he held in mating posi- tion with the stationary -carbon by a stainless steel spring.
