Non-Potable Water Operations Plan
6/13/2022
A written description of how the non-potable water supplies will move through the system to all areas
of use.
Response:
The system will be supplied from a combination of four potential sources which will be delivered to the
two ponds.
1. Surface water provided by Larimer & Weld Irrigation Company (LWIC Shares)
2. Reservoir water provided by Larimer & Weld Reservoir Company (LWRC Shares)
3. Irrigation well water from the S&F Agency Well
4. CLPWUA Irrigation well water from the Buderus #2 Well
The Bloom Development non-potable irrigation system is to be primarily supplied from the LWIC ditch
through the Trailhead subdivision. Two wells will be used in conjunction with the Larimer and Weld
water.
The system will be supplied from two irrigation pump stations.
• Pump- A: will draw water from the Recreation Center Park Pond at an approximate peak flow
rate of 850 gpm, and will serve all areas North of International Dr. (Approximately 59 acres).
• Pump-B: will be supplied from the South Pond at an approximate peak flow rate of 350 gpm,
and will serve all areas South of International Dr. (Approximately 24 acres)
Water resource reporting requirements by Deere & Ault provides a basis for Raw Water
availability, delivery, and average/dry year supply on a reduced volume of water for further review.
Please refer to the Deere & Ault report for more information.
The non-potable irrigation water system to deliver to the ponds will take place in two main
installation steps. At the point the Larimer and Weld water enters the site at Vine Dr., a measurement
structure meter, meeting ditch company standards, will be utilized to chart water deliveries to the site
and track surface water use. The 1st stage of the build out will consist of a temporary swale to the
proposed crossing of the railroad tracks. Water from the Buderus #2 well will flow from the north edge
of the property to the northern pond using the same channel.
At this point it will enter a structure and cross under the tracks via pipe into a distribution system. This
gravity system will divert flows to the proposed northern pond as well as the proposed southern
irrigation pond. An additional gate located at the junction to feed the southern irrigation pond will be
provided for a continuation of the feed to the south. In the ultimate condition the entire system will be
piped from the LWIC Ditch connection point on the north side of the tracks to the railroad track
crossing with the route depending on the ultimate layout for that portion of the development located
north of the railroad.
Each well is permitted to serve a specific area of the project. The S&F Agency Well may serve irrigated
landscape on the current Springer Property located on the South side of International drive. The
Buderus #2 Well may serve irrigated landscape on the current Whitham Farm which includes areas
located North of International Drive. The production of each well may be additionally limited by the
CLPWUA should surface water be utilized for irrigation on the project. The Deere & Ault report outlines
detailed water supply options as referenced below. Currently the non-potable water system, storage,
distribution and irrigation is designed to match the decreed area requirements for each water source.
As noted, there are 2 storage ponds provided for the non-pot system. The northern pond which is
included with Pond D as defined in the drainage report and the southern pond which is included with
Pond E as defined in the drainage report. These 2 ponds consist of irrigation water below the
stormwater detention storage. The North Pond irrigation is 9’ deep with a volume of 430,500 CF (9.88
ac-ft) and a top elevation for the irrigation of 4942.50. The South Pond irrigation is 9’ deep with a
volume of 174,200 CF (4.00 ac-ft) and a top elevation for the irrigation of 4939.50. Pond water levels
will be managed utilizing water level sensors located at the pond.
Use of well water will be prioritized during irrigation shoulder seasons, when surface water supplies
may not yet be available and when minor mid-season irrigation water requirements arise. Delivery
from each well to the pond will be controlled via lake water level sensor and coordinated
electronically with surface water deliveries. Each well will include a meter with remote read and
monitoring capabilities to manage water supplies.
It is expected that the non-potable irrigation water would be utilized within approximately 72 hours
and pond drawdown for irrigation would not exceed 24 inches (Essentially the irrigation water volume
would reside within the top 24” of each pond). The pond volume above would consist of detention
water and specific surface water shares with storage rights. Management of water sources and their
applicable use limitations will need to be managed appropriately.
Deere & Ault have provided a water supply analysis for the property in 2017. It included three (3)
potential water supply options to be reviewed and selected in coordination with the Client. Option 1 in
that report is the option chosen by the developer.
During an average year, it appears that a combination of surface water & well supplies provide ample
water through the irrigation season. In Option 1, Dry Year Yield is the lowest, however supply still
appears to exceed estimated peak irrigation demand. In an average & dry year, in each of the
available options, the water portfolio provides more than ample supply to meet the estimated
irrigation requirements for the site.
Daily, efficient irrigation system operation, water management to daily weather based requirements,
& timely identification & repair of system failures will provide a 20-30% savings over baseline water
use estimates.
A description of the non-potable irrigation system infrastructure and its status.
Response:
No system yet exists on-site. Please see above for a discussion of the current design. Hines will also
prepare a full user manual for the non-pot pumphouses and the system on the site.
A named point of contact with the Metro District(s) will coordinate with the ditch companies and other
supplies for deliveries.
Response:
Pinnacle will manage the Metropolitan District. The best contact will be:
Doug Campbell, Sr Facility Operations Manager
dougc@pcgi.com
970-669-3611 ext 139
A description of how usage records will be maintained. (If you have precedence for this)
Response:
As this is a new development, the Metro District will need to keep five years of data to establish
average usage of water. Deere and Ault recommend keeping the following information:
• First, last, and total delivery days for LWIC and LWRC
• Number of days per week LWRC is delivered
• Acre-feet per share of LWIC and LWRC actually delivered
• Total amount of well water pumped from each well
Additionally, Hines recommends the following records be kept:
• A surface water delivery schedule, utilizing average year yields and deliveries by month,
should be developed by a water resource engineer as a general guideline.
• A monthly recording of irrigation demand requirements will be kept by community
management. Water deliveries amounts, from both well & surface water sources should also
be provided for reconciliation of supply and demand calculations and reporting.
A named point of contact person for ELCO in the future in the event usage records are needed or other
questions need to be answered.
Response:
Pinnacle will track and maintain data on the non-potable system. The best contact will be:
Doug Campbell, Sr Facility Operations Manager
dougc@pcgi.com
970-669-3611 ext 139
A description of the timing of deliveries of the various water sources throughout the season. (or both of
us together)
Response:
Based on conversations with Shawn Hoff, the ditch rider for Larimer and Weld, surface LWIC water is
typically delivered beginning in mid-May. It typically continues through the third week of June. LWRC
water begins after LWIC water ends and typically runs 4 days a week, during the work week. LWRC
water typically runs until demand drops off, generally around Labor Day.
The Metro District will call Larimer and Weld to request the water the day before it is needed and
Larimer and Weld will then provide it. Water comes through Headgate 4, located in the Trailhead
subdivision. Cutting off water deliveries is done the same way.
Larimer and Weld may have surplus early- and late-season water, which can be rented if it is
available. Shawn Hoff is the best person to discuss availability and his information is below:

The Operation Plan should complement the Landscape Plan to provide ELCO an overview of how the
system will work.
Response:
The following parameters have been utilized to estimate irrigation water use for the project site.
Please refer to the irrigation master plan below for Water Use Estimates organized by Project Area.
• Landscape water use and irrigation water demands have been calculated using:
o Regional evapotranspiration (ET) rates averaged over 30-years
o Specific plant coefficients based on proposed landscape material
o Irrigation equipment efficiency data based on
Rotor sprinklers serving large turf and native grass
Spray sprinklers serving small turf areas
Drip irrigation serving trees and shrubs
o 8-10 hour watering window on common landscape areas
• Turf, shrub, & tree plant material will be permanently irrigated
• Turf is assumed to be a bluegrass/fescue blend
• Native areas will be irrigated for establishment
o Irrigate only during an establishment period of approximately 3 years
o Following the time for establishment, Native Grasses will be removed from seasonal
irrigation pending significant drought.
o Removing Native Grass from long-term supplemental irrigation may reduce ongoing
irrigation water requirements by nearly 40-acre feet annually.
o Hines recommends allotting a portion of annual water use to maintain native grasses
in a healthy state of dormancy during significant drought. This may equate to 30% of
the above amount noted depending on the quality of establishment, maintenance
practices, & severity of drought.
Open Space Landscape Area
Please refer to the irrigation master plan below for a specific breakdown of landscape areas as
provided by the project Landscape Architect. Additional clarifications are provided below.
The total landscaped area for the project is 230-acres, 39-acres of which is dedicated to common
area open space. 51-acres consist of landscape areas located within private areas of the project.
Landscape typologies include:
• Manicured turf
• Mulched planted beds
• ‘Dryland’ Native Seed areas
o Receive establishment water for 2-5 years after which supplemental irrigation will be
turned off pending severe drought
• Annual Project Estimated Water Use: 164 AF
• The Springer Fisher portion:
o 49 AF to meet annual irrigation requirements
• The Whitham portion:
o 115 AF to meet annual irrigation requirements
Native Grass Irrigation Reduction may be utilized following initial establishment of 2-5 years. As
currently designed, the project includes 35-acres of native grasses with a total annual estimated
demand of 39 AF per year which may be reduced or eliminated following establishment.
Please refer to the Irrigation Masterplan which documents landscape assumptions, & overall
water use requirements by landscape type for residential lots & open space areas as described
by the landscape architect.
Drought Contingency Plan(s).
Response:
Hines recommends additional, prioritized irrigation drought restrictions within the community to
support landscape in a healthy dormancy during the drought, while restricting irrigation water use to
meet reduced supplies. Priority planting would include trees and shrub areas, secondly active turf
areas and lowest priority would include native seed areas.
Hines’ recommendations are generally based on the City of Fort Collins Water Shortage Action Plan, as
follows:
• Level 1 Potential shortage of 1-15%: Respond with 1-15% Reduction – Achieved by stopping all
irrigation to native areas and reducing irrigation of turf grass by 8-10%,
• Level 2 Potential shortage of 16-25%: Respond with 16-25% Reduction – Achieved by reducing
irrigation of turf grass by 25% and reduction irrigation to trees and shrubs by only 3-5% as
these are the high value materials
• Level 3 Potential shortage of 26-35%: Respond with 26-35% Reduction – Achieved by reducing
irrigation of turf grass by 100%, and irrigation to trees and shrubs by 3-5%
Each level would also be subject to water times and day limits as required by the city.

Re: Review of Bloom Non-Potable Irrigation Proposal for Filing 1
Introduction
Hartford Homes seeks approval of a non-potable irrigation supply for outdoor water use on the proposed
Bloom Filing 1 development. ELCO Board approval would reduce ELCO’s Raw Water Requirement (“RWR”)
to indoor use only for single-family residential lots in the water service agreement for Filing 1.
ELCO Non-Potable Requirements and Criteria
To grant a reduction in RWR, the ELCO Board of Directors will need to know that the viability and reliability
of the proposed non-potable supply is the same as if the development were served potable water
provided by ELCO for landscape irrigation. ELCO will not provide potable water for irrigation should the
proposed supplies’ yields not meet landscape irrigation demand in the future.
General Information
Several developers in the ELCO service area have proposed to implement non-potable systems and
supplies as an alternative to using treated water for landscape irrigation. The price of non-potable water
rights is often much less than the water rights dedicated to ELCO for treatment at the Soldier Canyon Filter
Plant. Dedicating water to ELCO for indoor use only can result in a significant savings for the developer.
ELCO has not approved a non-potable water supply since 2015.
Overview of a Non-Potable Review
ELCO must thoroughly review each non-potable supply proposal to ensure the water supplies for
landscape irrigation are as reliable as treated water provided by ELCO. If a proposed development uses
potable water from ELCO for outdoor use, the developer must dedicate water rights with yields equal to
1.5 times the annual demand. This 1.5 multiplier is called the Supply Factor and provides for resiliency
and certainty through both the natural variability of water supply yields and periods of drought. For
example, if the annual allotment for a development is determined to be 40 acre-feet, then a developer
must dedicate 60 acre-feet of water rights acceptable to ELCO. (40 acre-feet x 1.5 = 60 acre-feet). In this
example, the developer could dedicate 1.0 WSSC share to meet the 60 acre-ft of demand. This is
consistent with ELCO’s application of a 1.5x Supply Factor for potable raw water dedications.
Information Required to Conduct a Non-Potable Review
Water Resources requires the following items to accurately determine if a developer has sufficient water
supplies to meet the projected landscape irrigation demand multiplied by the Supply Factor described

above. At a minimum, the required information includes the following for both proposed and existing
developments:
• Projected landscape irrigation demand prepared by a landscape design professional
• Actual landscape irrigation use if there are previous filings of the subject development
• Surface water sources and copies of ditch or reservoir company share certificates
• Groundwater sources and copies of decrees, well permits and documentation of the amount
augmented or other restrictions
• Decree or reservoir accounting data and submittals where applicable
• Proof of water availability during the irrigation season (May 1 through October 31)
• Plan of how the irrigation system will be operated
Hartford Homes has supplied all the required information for this analysis.

Non-Potable Irrigation Supply Analysis
Hartford Homes proposes a non-potable irrigation system for Bloom Filing 1 common greenspace areas
and residential lots. Filing 1 contains two tracts, Whitham and Springer-Fisher, with specific water sources
tied to each tract are discussed in detail below. Table 1 summarizes the proposed irrigated acreage and
subsequent water demand for each tract as provided by the Hines Irrigation Memo.
Filing 1 Whitham Springer-Fisher
Irrigated Acreage 64.8 25.4
Demand (acre-ft) 150.2* 47.6
Demand w/Supply Factor (acre-ft) 225.2 71.3
Table 1: Irrigated Acreage and Non-Potable Water Demand by Tract
*The irrigation memo provided by Hines has contradictory numbers for the Whitham demand. For this analysis, the
larger number was used.
Overview of the Non-Potable System Water Supplies
Bloom has water rights available through a combination of ground and surface water sources. Bloom
consists of two tracts of land, Whitham and Springer-Fisher, and the water rights owned by Hartford for
this development can only be used in the tracts to which they are assigned below.
Whitham Tract
• 4 shares of Larimer & Weld Irrigation Company (“LWIC”)
• 4 shares of Larimer & Weld Reservoir Company (“L&WRC”)
• Buderus Well
Springer-Fisher Tract
• 3 shares of Larimer & Weld Irrigation Company (“LWIC”)
• 2 shares of Larimer & Weld Reservoir Company (“L&WRC”)
• Springer-Fisher Well
Surface Water Resources – Larimer & Weld Irrigation Company
Per Kim Nelson at the Larimer & Weld Irrigation Company, the long-term average of farm headgate
deliveries for LWIC shares is 15 acre-feet per share. LWIC shares typically yield during May and June each
year.
Surface Water Resources – Larimer & Weld Reservoir Company
Kim Nelson also provided the long-term average of farm headgate deliveries for L&WRC shares, which is
12.5 acre-feet per share. L&WRC shares typically yield during July through October each year. Subtracted
from the L&WRC shares on the Whitham tract is 10.01 acre-feet required to replace the evaporation from
the Northern and Southern Ponds, which are both located on the Whitham tract of land. The amount of
water subtracted for evaporative losses from these two ponds is reflected in Table 3 below.

Groundwater Resources – Buderus Well
The Buderus Well is decreed for 269 acre-feet per year and can only be used on the Whitham tract of
land. The well is part of the Cache la Poudre Water Users Association (“CLPWUA”) augmentation plan,
meaning the amount of allowable pumping is based on the number of irrigated acres at a rate of 3 acre-
ft per acre of irrigated land. Based on the amount of irrigated acreage from the Hines report, Buderus
Well is estimated to able to pump up to 194.3 acre-feet per year. This well may only be used to irrigate
the Whitham tract. The acreage and volume were confirmed by CLPWUA on 7/25/2022.
Groundwater Resources – Springer-Fisher Well
The Springer-Fisher Well is decreed for 151 acre-feet per year and can only be used on the Springer-Fisher
tract of land. The well is part of the Cache la Poudre Water Users Association (“CLPWUA”) augmentation,
meaning the amount of allowable pumping is based on the number of irrigated acres at a rate of 3 acre-
ft per acre of irrigated land. Based on the amount of irrigated acreage from the Hines report, Springer-
Fisher Well is estimated to able to pump up to 76.3 acre-feet per year. This well may only be used to
irrigate the Springer-Fisher tract. The acreage and volume were confirmed by CLPWUA on 7/25/2022.
Bloom Filing 1 Water Balance
Tables 2 and 3 show the water balance calculations for the Whitham and Springer-Fisher tracts,
respectively. Both tracts meet the water supply requirement, which includes the Supply Factor, with
excess non-potable water supply remaining.

Summary
Hartford Homes has provided Water Resources staff the information required to do a non-potable
irrigation analysis for the proposed Bloom Filing 1 development. Bloom is divided into two tracts and each
tract has its own non-potable irrigation demand and raw water supplies. Based on the analysis of the
provided information, both tracts meet ELCO’s requirements for non-potable irrigation.
Recommendation
Water Resources recommends any approval of the Bloom Filing 1 Non-Potable Irrigation request have the
following conditions:
• Hartford Homes provides proof of ownership of all water supplies listed prior to signing a water
service agreement.
• A written guarantee that the water rights will be passed on to the entity managing non-potable
irrigation for Bloom Filing 1.
• Should a future filing of the Bloom development request to use non-potable water for irrigation,
the Filing 1 metro district, or managing entity, will be required to provide irrigation and accounting
records for the LWIC, L&WRC, Buderus well, and Springer-Fisher well.
• The Colorado Division of Water Resources has been notified of this project. If the non-potable
irrigation supply is approved by ELCO, Hartford Homes will need to coordinate with the Division 1
Assistant Engineer and Water Commissioner for approval of raw water measuring devices and
state accounting prior to starting the non-potable irrigation system.
• Additional conditions may be added to the water service agreement.
