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.

Water Projects

South Water Tank Project

In keeping with the 2016 Water System Master Plan, Town leadership is implementing needed improvements to the Johnstown water system by installing a new water storage tank on the south side of Town and a new water pipeline that will connect at the southeast corner of Stroh Farms and loop back to Town along Weld County Road 13 to Highway 60. This project will facilitate future planned growth as well as improve water pressure and delivery for both current and future residents of the southern area of Johnstown.

April & May 2021 Update - Town Staff is in the process of executing Contract Documents with the awarded construction contractor, CB&I Storage Tank Solutions. Construction is anticipated to start during the summer of 2021.


Water Treatment Plant Expansion

The goal of this project is to upgrade and expand capacity of the existing water plant to handle current and future population growth in the Town. The project’s design phase is scheduled to begin in 2021, with actual plant improvements and construction to follow.

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.

May 2021 Update - The 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.

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. The project design is planned to be complete by the end of year in order to be eligible to apply for a DOLA (Department of Local Affairs) grant to assist in funding a portion of the construction anticipated to begin 2022.

Old Town Drainage Project

The Town hired Tait Engineering & Associates in 2020 to complete a stormwater system design for the area of Old Town between N. Greeley Ave and Columbine Street from Charlotte St to N 2nd St. The Project involves the installation of 36 inch stormwater line with multiple inlets to catch surface water in order to address localized flooding in Old Town as well as the replacement of asphalt to help direct surface flows to street gutters. The project also includes upsizing two 6 inch sewer lines in order to provide the cost benefit of updating all underground utilities at once prior to repaving the construction limits for the Stormwater Project.

April 2021 Update – The Town is in the process of finalizing bid documents and soliciting bids for construction on the Old Town Drainage Project

North 2nd Bridge Project

The North 2nd Street Bridge project aims to widen the existing box culvert bridge crossing the Hillsborough Ditch in order to provide safe and reliable travel for vehicles and pedestrians commuting to and from Roosevelt High School. The North 2nd Bridge Project aims to address an unsafe squeeze point for both vehicles and pedestrian as well as to straighten the overall roadway alignment. Design and Construction is anticipated to be completed by the end of 2021 with construction occurring after irrigation season.

April 2021 Update – Staff is working on an RFP that will be issued in May to obtain a Consultant for the design and coordination of a new box culvert bridge structure.

Parks Projects

Lake Park Playground Project

The Town is working to upgrade playgrounds at our local parks. Lake Park is the next park identified for upgrades and will include replacing the ground beneath the playground from a woodchip base to a solution called “Pour-in-Place”. This new rubbery ground is safer, more reliable, and cleaner than the current woodchip base. Due to restricted funding this 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.



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.

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.

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

April 2021 Update – The Town held a Pre-Construction meeting with the Construction Contractor, Connell Resources, to start construction of Phase 1. The Town is also working with IMEG and Connell Resources to complete the design on Phase 2 of the project.
