Broomfield Comprehensive Plan 2016 Update Utility Work Group Report Utility Work Group: − Bob Pearson, Coordinator − Beth Willman, Recorder − Hal Lunka − Greg Stokes, City Council Representative

Utilities Vision Provides a utility infrastructure system representing state-of-the-art equipment, construction, management and conservation techniques to serve the needs of Broomfield through buildout new language

Utilities Operating in Broomfield City Owned Utilities − Potable drinking water − Non potable reclaimed water “Purple Pipe” system, irrigation for open space − Waste water collection and treatment Discharge only to Big Dry Creek to optimize water rights Provide treated effluent to non-potable system − Storm water drainage and flood control Discharge into Big Dry and Rock Creeks Non-Point Source Pollution Control Permit

Utilities Operating in Broomfield Franchise Utilities − Xcel Energy Electricity (generally south of 140 th ) Natural Gas (city wide) − United Power Electricity (generally north of 140 th ) − Comcast Cable TV, Internet and Telephone − Century Link Telephone and Internet − Cell Phone Providers Telephone

General Observations Broomfield has a well run water and wastewater utility department Utility service is uniformly good throughout the City and County − Some small areas on wells and septic systems − Some areas have road side drainage ditches Planning for future growth is being done properly − Water storage needed for new water sources − Renewable surface supplies

General Observations (con’t) Water and sewer lines in older parts of the City are starting to need replacement Messages from City about water conservation are not well read − Need to find more effective messaging approach Make sure security at 144 th Ave. water treatment plant is adequate

Current Water Supply Sources The Northern Colorado Water Conservation District Denver Water Department Reclaimed (treated) wastewater Raw water from water rights owned by Broomfield

Capacity of Potable Water System Build out need (37,300 tap equivalents) Present water supply (28,171 tap equivalents) − 8,994 acre-feet from Northern Colorado Water Conservation District − 6,500 acre-feet from Denver Water Future water supply (11,000 tap equivalents) − Windy Gap Allow for possible future higher density rebuilding after buildout

Capacity of Non-Potable Water Systems Non-potable reuse water − 3,100 acre-feet to irrigate 1,275 acres Big Dry Creek Wastewater Treatment Plant − 12 million gallons per day present capacity − 11.8 mgd needed at buildout − Will require three to five lift stations from east and north Storm water drainage and flood control − Broomfield is mainly within the Urban Drainage and Flood Control District (UDFCD) Except for lands annexed from Weld County

Big Dry Creek Plant Water Treatment Plant Great Western Reservoir (reuse water storage) Broomfield Utility Plants Chlorination Station

Water Resources for Future Growth Windy Gap Water − Diverted from Colorado River Near Granby − Junior Water Right Available only at high stream flow Water is taken when available and stored for later use − Requires Storage to “Firm” the Supply Grandby Reservoir (when storage capacity is available) Broomfield Reservoir (5,000 acre ft.) − Budget cost $75 million Chimney Hollow Reservoir (Broomfield share 25,000 acre ft.) − Broomfield share of budget cost $106 million

Seina Reservoir (reuse water storage) Broomfield Reservoir (5000 Acre ft) Broomfield Reservoir Glasser Reservoir

Planning Goals Adequately Plan and Coordinate Utility Development to Buildout − City Water and Sewer Utility Department Plan for 15 to 30 years into the future System expansion until buildout System repair, maintenance and replacement after buildout Finance Utilities for Buildout Sustainable Utilities − Rely on renewable surface water resources − Maximize water reuse

Planning Goals (con’t) Community Aesthetics − Build necessary “unattractive” facilities before nearby neighborhoods develop Public Health − Reduce residents on wells and septic systems State of the Art Communications Infrastructure − Encourage high speed fiber optic system throughout the City

New Recommendations in 2016 Plan Convene Annual Utility Planning Meetings − Linear utilities (water, sewer, Xcel, Century Link, etc.) − Cell phone towers Update Utility Master Plans on Regular Basis − Next update: Non-Potable Reuse Water Master Plan (2016) Pursue − Providing non-potable water to individual homes and businesses for irrigation − Allowing capture of grey water in homes and businesses for irrigation

New Recommendations (con’t) Water − Construct “Firming” Storage for Windy Gap − Rely on renewable surface water supplies − Improve consistent messaging from City to community on home water conservation efforts Encourage irrigation systems with soil moisture sensors Encourage xeriscaping

New Recommendations (con’t) Provide Adequate Resources to Replace Old Water and Sewer Lines − Mainly an issue in the First Filing − Some lines are 50+ years old and are getting expensive to maintain Bring all Sewer Lines to Big Dry Creek Plant − State of the art plant recently expanded − Requires lift stations from north and east − Allows greatest flexibility for balancing reuse and discharge Maximizes water available for reuse

New Recommendations (con’t) Re-evaluate trash removal − Recycling pickup city wide Compostable yard waste − Trash hauler pickup Compostable bags − City drop off sites − Send to Weld County Farm near Gilcrest − Make compost available to residents

New Recommendations (con’t) Improve electric and communication utilities − High speed fiber optic system city wide − WiFi in parks − LED street lights − Street light motion sensors − Move overhead utility lines to underground Solar Energy − Revaluate current contracts to own solar systems on City buildings − Hold seminars for residents considering solar
