Annual Projects & Programs

Mosquito Control Program

Mosquito Control Program

The Town of Johnstown has implemented biorational integrated mosquito management (IMM) through Vector Disease Control International (VDCI) for many years. The primary objective of this program is to monitor and reduce mosquito populations through the use of specific, environmentally sound, control techniques in order to protect residents from the threat of mosquito-borne diseases. 

Open communication is maintained by VDCI between the Town of Johnstown, County Departments of Health & Environment, the Colorado Department of Public Health & Environment and surrounding municipalities in order to ensure that the highest level of mosquito control and epizootic response is achieved. This diligent and cooperative communication is important to the Town of Johnstown’s mosquito management program and provides significant benefit to public health throughout the entire area.

April & May 2021 Update The Town is in the process of evaluating which design direction to pursue in order to address Taste & Odor water quality issues.   The proposals for the Design RFP on the Water Treatment Plant Expansion project are under review with the intent to award in the next month in order to start moving forward on design plans.

January 2021 Update The Town posted an RFP on December 30, 2020 to hire an engineering firm to design the expansion of the Water Treatment Plant from 5 MGD to 10 MGD. Bids are due on February 5, 2021 with a planned recommendation to Council in March 2021.

Addressing Water Taste and Odor Issues

The Town of Johnstown Public Works Department is working aggressively to improve water taste and odor issues for residents. While the taste and odor issues experienced in Johnstown are not a health or safety concern as measured by the State, the issues do greatly impact the enjoyability of the water. The goal for the summer of 2021 is to address taste and odor water issues with the installation of a new Granular Activated Carbon (GAC) Feeder system. Staff will be working with residents to obtain feedback regarding the quality of the Town’s water after  the GAC System installation.

August 2021 Update - The GAC and ultrasonic buoy system are fully installed and up and running providing better tasting and looking water to Town of Johnstown residents. Public Works is still working on installation of the PAC system, as parts have been delayed as a result of COVID-19. Once the parts are available, the Town of Johnstown Public Works Department will work quickly to install the PAC at the Lonetree Reservoir. 

July 2021 Update - The Granular Activated Carbon (GAC) system is up and running. All 6 vessels are in full operation producing 3500 Gallons Per Minute (GPM) in treated water to address taste and odor issues. Residents should begin noticing a difference in the taste and odor issues of the water over the next few days as the water currently in the system moves out and water treated through the GAC is introduced into the distribution system. At this time, the ultrasonic buoy is being assembled and will be placed into the Johnstown Reservoir as soon as it is finished. 

June 2021 Update - Please see the Press Release that went out on June 14, 2021 for June's update. All 3 systems (GAC, PAC, and Ultrasonic Buoy) are on time  and scheduled to be installed and online by the end of June - weather and provider pending. 

May 2021 UpdateThe GAC system is in the process of being installed with the concrete foundation having been poured the week of May 17th. The ultrasonic buoy for the Johnstown Reservoir has also been purchased and will be installed upon delivery. The ultrasonic buoy will sit around the center of the reservoir and will prevent algae from growing in the hot summer months (the algae is a harmless but major contributor to the taste and odor issues being experienced).

April 2021 Update - In April, the Town Council approved the purchase of a Granular Activated Carbon (GAC) system that will begin to address 70-80% of the water taste and odor issues being experienced by residents and is expected to be installed and operational by this summer. This is the first step in addressing the Town’s taste and odor issues and will involve public outreach and input to determine the next steps to reach a goal of 95% removal or better. In addition to the GAC, the Town has also ordered an Ultrasonic Buoy to be installed in the Town Lake which will work to reduce existing algae and prevent new algae growth (a major contributor to the taste and odor issues throughout the hot summer months). As these new parts of the Town’s water infrastructure are installed, the Town will continue to update residents. More specific details can be found in the Town Council Work Session Packet for April 12, 2021​. 

December 2020 Update - The Town has hired Design Consultant (Burns and McDonnel) to perform a study regarding the Town's water taste and odor issues. The study will be used to determine the next steps required by the Town to install a new granulated carbon feeder system in order to make the largest impact on the water quality for residents. 

Street Projects

Charlotte St. Rehabilitation and Improvements

Charlotte Street between Letford Elementary and Parish Park has been identified through a Roadway Condition Survey to be in need of rehabilitation; specifically, the reconstruction of asphalt pavement and concrete as well as the replacement of aged water and sewer lines as well as the installation of new stormwater lines to address surface flooding issues. The Town  plans to explore multimodal transportation options along Charlotte Street that may include dedicated bike routes and wider sidewalks to increase safety and walkability.

July 2021 UpdateThere will be a Public Meeting (#2) held on July 27, 2021 at Town Hall from 6pm-7:30pm. At this second open house, get an idea of the suggested changes that the Town has made to the project as a result of feedback. Please attend to  provide additional input and ask questions!

June 2021 UpdateThe Public Works Department held 2 Public Open Houses to discuss potential Charlotte St. Improvement ideas at the end of May. Residents provided feedback from the end of May into June regarding project ideas and street needs and this feedback was brought to Town Council during a work session on June 14.
The next steps for the Town are to reevaluate the project direction in order to preserve the historic character of the street by working around the established trees, addressing flooding, improving sidewalks to meet ADA requirements, and upgrading aged utility infrastructure. Another open house will be held to share these updates with the public and discuss design challenges along the Charlotte Street corridor.

May 2021 Update - There will be two public Open Houses for the Charlotte St. Project. The virtual open house will be May 25 and the in-person open house will be on May 27. Please see all information related to these opportunities at the top of this page.  

April 2021 Update - In April, Town Council awarded the design consultant for this project to Tait & Associates Engineering and will be presenting design concepts to residents for input.

Parks Projects

Playground Projects

The Town is working to upgrade playgrounds at our local parks: ground materials as well as playground equipment. We will announce the next park identified for upgrades below. Upgrades will include replacing the ground beneath the playground from a wood chip base to a solution called “Pour-in-Place”. This new rubbery ground is safer, more reliable, and cleaner than the current wood chip base. Due to restricted funding the Pour-In-Place upgrade will not occur until 2022 and will require a 2-3 week closure for the installation of the Pour-In-Place. The rest of the park will still be accessible by the public as this only impacts the playground. The Town will announce park closures as they become relevant.

August 2021 Update - Public Works Staff is in the process of selecting the new Rolling Hills playground equipment that will be installed by the end of the year. This equipment replacement will NOT include the rubber-grounding (pour-in-place) and will be announced as the date for the work is confirmed

July 2021 Update - The Town can confirm that by the end of the year, Rolling Hills playground equipment will be replaced. This equipment replacement will NOT include the rubber-grounding (pour-in-place) and will be announced as the date for the work is confirmed. 

June 2021 Update - Either West Lake playground or Rolling Hills playground equipment will be replaced by the end of Summer 2021. This equipment replacement will NOT include the rubber-grounding and will be announced as the date for the work is confirmed. 

Sewer Projects

Low Point Water Plan Expansion 

The goal of the Low Point Wastewater Treatment Plant Expansion project is to expand the current treatment facility through equipment and operational upgrades to better serve residents. The expansion will increase treatment from 0.5 MGD to 1.5 MGD tripling the plants current capacity.

June 2021 UpdateTown Staff and the Contractor for design are nearing the final design stages for this project. Start of construction, weather permitting, will be in Fall 2021. 

April 2021 Update - In April, the RFP for the Low Point Expansion Equipment was awarded to Huber Technology Inc, Hydro International, Suez WTS Systems USA Inc, Aerzen USA, Trojan UV, Fournier Inc. These vendors will be working with the Design Consultant, Aqua Engineering, on the expansion project. Specific cost information can be found in the April 5, 2021 Town Council Meeting Packet. The Town is in the process of evaluating Construction Contractors to perform the expansion.

Central Wastewater Treatment Plant

The Central Wastewater Treatment Plant project involves the design and construction of a new  wastewater treatment facility. The Town’s current wastewater treatment process consists of a lagoon system built in the 1950s. This type of treatment no longer meets State compliance due to the amount of growth the Town has experienced nor is the treatment process the most efficient or effective to meet Town needs. The new wastewater treatment plant is intended to increase daily flows from the current .999 MGD to 2.5 MGD. The Town plans to begin design for the Central Wastewater Treatment Plant in 2021, with actual plant improvements and construction to follow.

July 2021 Update - Aqua Engineering has confirmed completion of the contract for this project with the Town of Johnstown. Design planning for this project has begun. 

June 2021 Update The design engineering contract for the Central Wastewater Treatment Plant has been awarded to Aqua Engineering. Aqua Engineering has worked with the TOJ previously during the design phase for Low Point and understands the Town's needs and will develop the best design approach to meet those needs. Another benefit of the awarded consultant: consolidating the design approach for the Town's two wastewater treatment plants to the same treatment approach to allow for Staff to rotate and manage operations easily and consistently provide the opportunity for better service. 

April 2021 Update - The Town posted an RFP in January to hire an engineering firm to design a new Central Wastewater Treatment Plant. The proposals for the Design RFP on the Central Wastewater Treatment Plant project are under review with the intent to award in the next month in order to start moving forward on design plans.

Central Sewer Interceptor (CMAR)

The purpose of the Central Sewer Interceptor Project is to upsize the sewer trunk lines to the Central Wastewater Treatment Plant. The project is planned to occur in 3 phases that enable the Town to better serve current residents, continue to meet State requirements, and accommodate current growth patterns.

Phase 1: Construction has started
Phase 2: Design is underway

Phase 3: Concept Planning

July 2021 Update - Phase 1 of this project is still underway - and the construction occurring under HWY 60 should be completed by the end of August (weather and materials permitting). There are still no expected service disruptions or closures as a result of this work. 

June 2021 Update - Phase 1 of this project is underway. Phase 1 includes: new lift station and 1 mile of pipeline to the wastewater treatment plant. There are no expected road closures or service interruptions as a result of Phase 1.
