Greeley’s Economic History

 Union Colony founded 1870 as agricultural utopia

– Irrigation ditches dug 1870 – Potatoes were first major crop – Sugar factory built 1902: by 1920 Colorado produced 25% of nation’s sugar – Lamb feeding began winter of 1884-1885 – Monfort packing plant brought cattle to feed lots

 Greeley is Weld County seat  University of Northern Colorado and Aims C.C.  Kodak and State Farm in late 1960s  Regional Northern Colorado Medical Center  Oil and Gas industry  Railroads: UP, Burlington Northern, Great Western

Greeley’s Water Supply Today and Tomorrow

 Four river basins  Two Filter Plants  Two transmission systems

6

Water from Four Basins

 Poudre River Basin – Direct flow river rights (1860’s) – Ditch Number 3 (1870) 3/8 + 20% of 5/8 GIC – Six high mountain reservoirs (1947)  Upper Colorado River Basin – Colorado-Big Thompson Project (22,000 units) (C-BT) – Windy Gap Project (44 units, 10% of project)  Big Thompson River Basin

– Greeley Loveland Irrigation System (50% of company) » Boyd Lake, Lake Loveland, Seven Lakes

 Laramie River Basin

– Laramie-Poudre Tunnel (Windsor Reservoir&Canal Co) – Bob Creek

Water Rights – Redundancy

 When your direct flow rights are called out,

you have to use your stored water.

 Greeley has about 9 months water supply in

storage, enough to supply today’s population during a 6-year long, 50-year drought.

 For 3 months starting in June – Greeley was

without direct flow rights

 Due to drought conditions and Post Fire

Effects – Adequate Water Year?

Greeley’s 2060 Comprehensive Plan

 The 2060 Plan was adopted in 2009  Update of “2020 Comp Plan” approved 2000

– Reviewed key community indicators, trends, projections to assess growth and development

 Adopted unanimously by Council with community

testimony of support and no objection

Map

• Greeley Water is a service provider for the City’s planned growth

15

Driving Factors of Water Master Plan

 Age – Major parts of Greeley’s water system

are 50 to 70 years old.

 Growth /Demand– Population will over

double in 50 years.

 Regulations – higher federal water quality

standards: crypto, TOC, …….

 Competition – Regional growth limits water

availability and pipeline construction.

16

Water Master Plan is Comprehensive and Long-Term

 Four years in the making, developed by

staff and Board with consultant’s assistance and community input.

 Adopted by Council and Board.  Provides capital improvements plan for

near-term (10-15 years) and water supply

• ptions for long-term (20-40 years).

 Provides water supply and funding concept

beyond 2020: regional storage and future water account.

Drought

A regular occurrence in a semi-arid environment.

On the Demand Side

21

Comprehensive Conservation Program

 Fully metered since 1996  Leak detection: less than 5% system losses  Continual watering restrictions since 1907  Free irrigation & commercial audits, rain sensors

– JBS-Swift industrial conservation audit completed – Parks irrigation control system upgraded

 Rebates for high-efficiency washers and toilets

– 11th Avenue toilet replacement program

 Required soil amendments; grants for xeric  Water Budget Pilot Program  Continual Education (e.g. water festival, mailers)
