Water and wastewater capital projects

undergrounding a power line that serves our wastewater plant and then also undergrounding to our south along Highway 93

In regards to water, wastewater, storm water management, and flood control, staff also found there were adequate facilities

that increase fees by 5% for water utilities, 7% for wastewater utilities, and 7% for storm water flood

So the wastewater um uh blueprint, the um uh transportation blueprint, these are the plans that anticipate future demand

And then those impact fees over time get aggregated to increase the capital structure of say a wastewater

upon completion of the water system, properties must connect exclusively to city water.

we're thinking about our, Major phosphorus upgrades project that took place at the water resource recovery facility.

would be done specific to plant infrastructure or the distribution center, and decisions have to be made

people invest in their fair share of the plant, or the treatment plant, or wastewater treatment plant, and the pipes and distribution

larger wastewater system, the larger sewer system on what amounts to a a per capita basis

the baseline off-site infrastructure costs, including the water lines and wastewater treatment, could reach a billion dollars

Our utilities department really had a demonstration of why capital investments matter.

Water, wastewater, and stormwater management and flood control public facilities are guaranteed by an enforceable development agreement

increasing reliability, resilience, and level of services of the water, wastewater, and storm blood infrastructure

they provide lowinterest loans for local drinking water and wastewater infrastructure projects

That would be a difficult endeavor, or an expensive endeavor for Boulder, because one, we're already a built-out city, so you'd be tearing up a lot of roads to run new pipes.

so that we're not outgrowing our facilities and infrastructure

the water utility fund will support the transmission uh system repair project

definitely want to have a long-term picture of what our infrastructure needs are.

so much of the capital improvement is focused on transportation and utilities

I know there's been some issues of budget for their wastewater system and that sort of thing.

for the remaining projects in the water, wastewater and stormwater and flood management utilities

that's really why we're binding differently in the storm flood utility versus the water and wastewater utility

We do have a bump in our capital spending after this year.

3B is the consideration of a water and wastewater service agreement between the city of Boulder and the University of Colorado at Boulder

a large portion of that bond helped to pay for the MS project

we did recommend a 6% increase for 2027. Um, but due to some, you know, growing capital deeds

we have an ongoing corrosion control disinfection uh project at the Passo water treatment plant

what you're seeing is Boulder Creek has been diverted so we can put the pipes in and lower them under the creek

So from the treatment plants, we have 2 treatment plants here in the city.

So treated, water system really made up. We have water treatment, and we'll do a couple of slides on each of these.

years ago I think we did study what it would take to replace whale Water and Wastewater systems within the parks in the city

The wharf is being upgraded in order to comply with future phosphorus limits.

The 63rd water treatment plant upgrades that were to replace aging infrastructure was substantially completed.

while several large capital improvement projects were advancing in the collection system and at the wharf

we would need to construct a whole new set of infrastructure

check out what the infrastructure costs for the city, go to the reservoir. The water treatment plant

I'm going to testify, just testified with them about water issues for all this growth that's going on.

That's the largest singular pump station in the city of Boulder, and is really the workhorse for getting water

also doing a number of uh upgrades at our water treatment plants and our wastewater treatment plants

in our Capital plans for water and wastewater um we have major transmission lines in the water system

really modeling of the water and wastewater system in particular

and then the thought was to do the November Board meeting at the 63rd Street Water Treatment plant and do a tour of some of the capital project work

the main sewer improvements Phase 2 project is included in the six-year CIP for a total of 9.7 million

a short business meeting and a tour of some of the 63rd Street upgrades or the 63rd Street Water Treatment plant

those larger diameter trunk sewers are all collected on the east side of town in our main interceptor

we're gonna talk about the main sewer Improvements project

Wastewater developed into or sent into the farmers, ditch

So my preliminary evaluations indicate on and off site improvements to the transmission and distribution.

So additional analysis is really required to understand on site and off site improvements as it relates to water, wastewater, etc

Boulder does not have wastewater infrastructure within the planning reserve, and there's no existing stormwater master plan

we talked about potentially bonding in 2028 or 2029 for projects within our water and wastewater funds.

preliminary evaluation has indicated on and offsite upgrades will be needed to the transmission and distribution infrastructure

understand some of the offsite improvements including water and wastewater treatment capacity and infrastructure

we're looking at in 2029 and cip the yellow areas is a phase 3 project

looking at beginning preliminary design work on the tank from Chautauqua in the Chicago area in 2025

3 big projects that we've got in Cip related to the Barker outlet

this is the single largest capital project the city has taken on from a utility system

this slide really shows the Sanitary Sewer Rehabilitation project that we've been going forwards with since 2015.

I'm gonna start with just a quick update on the industrial Pre treatment program. This was in your packet

We are currently performing major capital improvement program updates at the 63rd Street water treatment plant

The city has a history of investing in backup emergency power options for our critical water and wastewater facilities.

Carter Lake pipeline was one uh we had a big one down in

the capital projects we have across all of all three utilities water Wastewater storm and flood

team that does all the capital projects across all three of the utilities water Wastewater storm water and flood

technical infrastructure study to understand the costs and the feasibility of potentially extending city services

Do you know what actions can be taken in that arena that help produce those numbers like more driven more by the efficiency of the water treatment plant

do we have an infrastructure report on impact 2 and requirements from our water and wastewater systems by this project?

We could see that there's a lot of, you know. There's a lot of excess capacity there, because water is going down.

capital improvement work that we've done since then, like the improvements to the wastewater collection system

this was used to fund major upgrades to both liquid stream and solid stream processes at the waste water facility

we put about 40 plus 1 million dollars into the car. Really pipeline for the from Northern water

Now, I'm going to talk about some of this wastewater utility projects wastewater master plan

It's important project, valued at about 5 million dollars is part of several major sewer improvement projects

the electrical and high Service pump station project at the 60 Third Street Water Treatment

a 3 year project which will improve the dam stability and storage volume of Albion Reservoir in the city's upper watershed

our main sewer Improvement project all of the Wastewater collection pipes in the city

we have a couple of water treatment plant projects important ones Electric System up upgrades

keeping up with aging infrastructure is really our biggest challenge in utilities

we have two other utilities water and and Wastewater we'll have future Master

how we cycle through all of our systems and water and wastewater and storm and flood

the four million dollar comes from an estimation of what it would cost to connect utilities to city water and wastewater

Of rainwater that enters our wastewater collection system, and we have certain level of service goals

this is a project that will increase the capacity of our wastewater collection system

major investments in water wastewater stormwater projects that also includes

a big chunk of those numbers in our budget are utilities so water wastewater and storm water are a huge component of the funding

this is our main sewer interceptor project so this is the main sewer that leads basically from from all of town

three large water utility projects one large wastewater utility project

a contemporary problem however is that clay tiles were used for the pipes and they were used for many decades

continued work around the aging infrastructure and capital improvement projects for utilities

so the middle photo on this slide represents replacement of the the main Interceptor uh Wastewater pipe

in our water utility we have critical system components that in some cases are 100 years old

upgrades to the 'but a so water treatment plan resulted in a 20% improvement in filter efficiencies

the spike in 2222 reflects large projects and the utilities specifically around regulatory improvements to the boulder water resource recovery facility

that the systems could handle in terms of water and wastewater

so the utility fund just for an example the wastewater fund has 32 million dollars alone in CIP

our own water treatment plant and our own sewer plant and the sewer plant by state law has to be brought up to code

the wastewater treatment plant has just commissioned a study to look at upgrading our digesters out there

aggressively go after our aging clay pipe wastewater collection system and that allowed us both to implement a comprehensive inspection program

I've focused for 2019 both in capital and operating as on asset management and regulatory compliance

that is a Carter Lake pipeline which is about 32 million dollars
