Build Resilience into Water Reuse Infrastructure and Systems

August 14, 2023
By Bill Alms, Project Manager, WSB

The Midwest is experiencing a drought this summer. High temperatures and scarce precipitation have led many communities to implement watering bans and other solutions to help manage limited water resources.

For community leaders, it’s crucial to recognize that addressing drought and the impacts of climate change is a marathon, and not a sprint. While drought is top of mind for communities right now, it is equally essential to adopt a long-term perspective, and explore investing in systems and infrastructure that will minimize the impacts of drought and flooding in the long term and protect potable water supplies.

How can communities think long-term about water resiliency, reuse systems and planning? Here are some things to consider.

Invest in Resilient Water Systems that Can Handle Climate Extremes

Cycles of drought and flooding are becoming more common as global temperatures rise. Ensuring access to clean, safe water is critical for communities, and that means investing in infrastructure and water reuse systems that are efficient, effective and resilient.

WSB worked with Hugo, Minnesota on a sustainable water reuse strategy more than a decade ago, helping them build resiliency into systems. From reducing potable water use in landscaping, to placing reservoirs in strategic locations to ensure adequate water supply for high use areas, to educating the public on the importance of water conservation and reuse, the city’s water reuse strategy has been successful. It’s also made their water systems less susceptible to drought and climate change.

Communities looking to find similar success should approach water reuse and infrastructure in steps.

  1. Start with a feasibility analysis. Communities should begin with a feasibility analysis to determine areas with the lowest water supply, high water consumption, and inefficiency points. Based on this analysis, authorities can establish priorities, discerning which places require the most water and where there is greatest demand. Facilities like athletic complexes, schools, and manufacturing plants, which consume substantial amounts of water, should be evaluated accordingly. Pairing a usage map with existing sources can help determine how to build a more integrated and efficient system.
  2. Think regionally. It’s important to think regionally when planning for water reuse systems instead of site by site. How far apart are water sources? Where is the greatest consumption? Thinking about how pump systems can serve larger areas, placing retention ponds in strategic locations best suited to collect stormwater, and connecting water sources across a community promotes greater efficiency and benefits the environment, especially under drought conditions.
  3. Understand the value of long-term investments. When investing in more resilient water reuse systems, communities may be deterred by significant upfront costs, but the long-term benefits are significant. Communities should look at water reuse systems like other utilities and how to best maximize return on investment for everything from pumps to irrigation systems, to reservoirs. Adopting large-scale water intake and distribution infrastructure to meet specific needs minimizes water waste, as well as reduces the negative impacts from drought and flooding cycles. Numerous grants and funding sources are available to help design and implement water reuse projects.
  4. Engage residents. Public buy-in for reuse systems is important to foster conservation best practices and reduce the strain on groundwater reservoirs. More efficient systems and incentives for users can also significantly reduce the strain on water supply systems.
Take Advantage of the Drought

In the short term, many water basins are running low or are dry. While this situation poses many problems for communities, and reinforces the importance of resilient water reuse infrastructure, drought also provides an unexpected opportunity for critical maintenance work. Routine maintenance or fixing erosion or failed intakes and outfalls, for example, can be difficult when water levels are normal or high. Low water levels provide a meaningful opportunity to ensure systems are functioning properly, and access equipment that may normally be underwater.

Supporting the Infrastructure of an Entire Community

July 18, 2023
By Brian Bourassa, VP of Corporate Development

Investing in the vitality of the city of Lino Lakes, Minnesota.

At WSB, we use the term infrastructure broadly to define the places, spaces and systems that support our lives.  As important as infrastructure is to our way of life, we don’t often think about it until something goes wrong.  We’ve been privileged to support communities across the U.S. with their infrastructure needs. The scale of the projects may vary, but the impact is always significant.  

For the last several decades, the city of Lino Lakes, just north of the Minneapolis-St. Paul metro, has been investing in their infrastructure across the community.  In the end, it’s not one single project that has helped to build a vibrant community, but rather the collective investment in varying infrastructure. These investments have played a vital role in spurring development and progress within the city.

1. Biological Water Treatment Plant

The city is currently planning to construct a water treatment plant due to some of the city wells having manganese levels above the recommended guidelines. A biological treatment approach is unique because it relies on natural microbial activity to remove contaminants rather than chemicals, an environmentally sustainable strategy.

2. West Shadow Lake Drive

West Shadow Lake Drive is a residential street that was plagued by potholes, had no sewer or water, and faced challenges from high groundwater levels due to its proximity to Reshanau Lake. As part of the city’s pavement management program, the road was removed and replaced to support the city’s roadway infrastructure and sanitary sewer, watermain and storm sewer infrastructure was also installed. In addition, environmental work and wetland enhancements occurred throughout the area.

3. 12th Avenue Trail Project

The 12th Avenue Trail connection was identified as a priority in the city’s Comprehensive Parks and Trails System Capital Improvement Plan due to the lack of trail connection along 12th Avenue.  Prior to project completion, the busy rural road was narrow with unsafe conditions for pedestrians and cyclists. The project resulted in increased safety and a more bikeable, accessible community.

4. Master Plan and Comprehensive Stormwater Management Plan

Located in the northeast corner of Lino Lakes is a 1300-acre greenfield area that is prime for development opportunities. WSB was contracted to develop a master plan, comprehensive stormwater management plan and update the Alternative Urban Areawide Review (AUAR) for the area. Development opportunities will include residential, industrial and commercial that will spur economic activity in the area. 

5. The Rookery Activity Center

When the local YMCA closed in 2020 it left a hole in the community. The city of Lino Lakes took action to reinvigorate the space. To establish itself as a new asset within the community, the building needed an overhaul, not just in amenities and programming, but also the brand.  WSB worked with the city to develop a story, identity and brand assets.

6. Tower Park  

Tower Park is located on a 60-acre piece of land that was purchased by the city over 20 years ago.  The city council felt strongly about developing the space into a destination recreation area for the community.  WSB provided the park master plan and phase 1 design support. Tower Park is now home to some of the city’s most popular pickleball and tennis courts.  The project was completed last year. 

7. Birch Street Roundabouts

Birch Street is a heavily traveled roadway through the city with frequent accidents occurring due to the number of entrances to the high-speed roadway.  There were safety concerns from residents and a nearby school. To help alleviate the number of accidents and increase safety, several roundabouts, medians, crosswalks and safety signage were added.

8. Gateways to the City – Placemaking

Lino Lakes is a proud community and wants to enhance their welcoming presence by creating placemaking monuments at city entrances. The project is still under development, but once complete, the entrances will offer a ‘front door’ to the city and will invite visitors and residents to step inside and explore the community.

9. Feasibility Study – Lake Amelia Subwatershed

A 255-acre subwatershed of Lake Amelia is currently undergoing a feasibility study to address existing stormwater management concerns and anticipated future land use changes to the area.  The short-term phase includes solutions to address flooding concerns.  The long-term phase proposes more holistic improvements to the corridor that that would occur alongside its eventual development. The study will help guide future planning in the area and will ensure that the area is prime for development.

10. Shenandoah Park Improvements

In partnership with the Rice Creek Watershed District, the city is exploring multiple improvements to the Shenandoah Park area to improve water quality, ensure its habitat is supported, and create a destination for park users. WSB is currently exploring water quality improvement options, wetland restoration, flood retention and greenway spaces to support the goals of the watershed district and the city.

Designing Drainage Systems for Renewable Energy Sites

By Dan Cazanacli, Project Manager, and Henry Meeker, Graduate Engineer, WSB

When designing drainage systems for renewable energy sites, many different surface water factors must be considered to ensure a well-constructed system. These factors include how floods can impact the site, how water damage affects equipment and access points, soil erosion, water regulations, and how runoff impacts the surrounding ecosystem.

Floods can cause both widespread and deep channelized flow across solar farms.

Designers need to understand how water will flow across the site in different flood scenarios. Many renewable energy sites are located near floodplains, which can make the design process even more complicated. To tackle these challenges, WSB engineers use sophisticated 2D hydraulic models to map the direction, depth, and speed of water flow across the site.

Stop water damage to critical site components.

A crucial part of the drainage systems design process is ensuring that water, in any scenario, can flow smoothly across the site without causing any damage or flooding to critical components, such as inverters or battery storage units. Designers use the results of the hydraulic models to find the best solutions for water flow and to place these critical components away from the main flow of water. The models are also used to identify areas where water flows too quickly. WSB develops erosion control measures in these situations, such as reinforcing road surfaces at low water crossings.

Plan for ground erosion around solar panel support piles.

Another important aspect of renewable energy site design is ensuring that the supports for the solar panels can withstand strong winds and flooding. Each site is unique, our engineers work closely with our clients to use the results of the hydraulic models to assess the potential scour depth, meaning the point in the ground where erosion could occur, around the support piles and identify the appropriate methodology to use. This determines the best depth for embedding them. The models can also be used to identify areas where water is flowing too quickly and to develop erosion control measures, such as rock stabilization.

Consider water quality and management regulations.

Designers also need to consider regulations around stormwater management, water quality, floodplains, wetlands, and critical species/habitats. Project timelines will be significantly delayed without proper planning and consideration of these factors. WSB works to minimize the impact of the site on these sensitive areas while ensuring that the project proceeds on schedule. This often involves working closely with local government units and obtaining the necessary permits.

Protect ecosystem health.

Designers must understand how solar panels interact with the surrounding vegetation and soil. Major institutions, like the University of Minnesota, are performing ongoing research into how panel runoff affects water infiltration and an ecosystem’s health that will be incorporated into designs. Designers can leverage these findings to optimize water quality benefits for the site, incorporating water quality basins, pollinator-friendly vegetation, and site-specific erosion control measures.

Snow Melt Offers an Opportunity to Improve Flood Management Systems

February 13, 2023
By Bill Alms, Project Manager, WSB

Since 2020 Minnesota has experienced drought conditions, with less than average rainfall. The five years before that, Minnesota faced several extremely wet years, and communities were more prone to flooding with average rainfall as much as a foot above average.

This winter, Minnesota has already received well above average snowfall, similar to the winter of 2019-2020. If snow melt trends stay similar this spring to the spring of 2020, it may offer communities a unique opportunity to measure flood storage capacity, identify underperforming outlets, and update flood resiliency plans based on real time data. 

Why This Spring May Provide the Perfect Test Case

Coming off of a wet summer and a snowy winter in the spring of 2020, many communities saw flood storage capacity at its limit. Numerous reservoirs and ponds were high or overflowing, and communities struggled with underperforming drainage outlets. 

Now, this year many of those basins and ponds are low due to ongoing drought and extremely dry conditions – the opposite of 2020. However, with similar snow melts expected in the spring of 2020 and our upcoming spring, this could be an opportunity to reexamine those stormwater basins and assumptions around storm events. 

In short, this may be a rare opportunity to compare real world outcomes with projected models in flood resiliency plans. 

Updating Flood Management Systems 

If outlets flood again this spring with similar snow melts, coming off drought conditions, it is an indication that flood capacity needs to be expanded or elevation increased. It may also indicate where underperforming outlets need to be redesigned or rethought to better reduce flood risk and protect infrastructure. 

Smart technology tools can help determine where to add more storage and how communities can do next step planning on flood mitigation. Communities can install pumps within storm basins, for example, in areas that need more flood storage.

Other Tools to Address Flood Risk During Spring Snow Melts

In addition to updating flood management systems this spring, communities should also ensure they are acting on current flood management plans and tools to prevent flooding and protect infrastructure. This includes zoning areas that need the most attention, educating residents on the importance of removing ice and snow at low points and ensuring storm drains are clear, sandbagging structures if necessary, pumping areas with poor drainage patterns, and more.

Leaves

When the Leaves Fall: Proactive Leaf Management Tips for Communities

November 15, 2022
By Jake Newhall, Project Manager, WSB

Autumn is in full swing. While the arrangements of red, orange, and yellow are stunning, the mass collection of leaves that enter a city’s sewer system after a rainfall can cause serious damage – from clogs to flooding to pollutants in our waterways. 

When the Leaves Fall

When leaves fall, especially when followed by heavy rainfall, leaves on roads, sidewalks, and other impervious services can wash down into city sewers. When the leaves break down and decompose, the nutrients they contain can end up in water. This leads to harmful algal blooms and degraded water quality in rivers, streams, lakes, and other water bodies. 

Additionally, too many leaves washing down stormwater systems can also clog pipes and drains, cause localized flooding, and lead to expensive maintenance costs for cities. 

How can cities proactively address fall foliage and prevent these issues? Here are some tips and tricks. 

Targeted Street Sweeping

The first thing communities can do to avoid these problems is establish a targeted street sweeping plan which analyzes and maps impervious surfaces and high tree canopy coverage areas, as well as their proximity to high-value water resources. Street sweeping is one of the most cost-effective methods to reduce pollutant and nutrient loads to waterbodies and can be very helpful in achieving TMDL goals.

While leaf fall can happen at different times each year depending on several factors including weather, an efficient street sweeping plan prepares communities to manage and strategically target optimum leaf removal.  

Community Education 

Another thing communities can do to help prevent leaves from clogging drains and entering into waterways is to educate residents and private property owners about best practices in autumn. Raking leaves, bagging them, clearing the gutters near private properties, Adopt-a-Drain programs, and properly disposing of the leaves can go a long way in reducing the total amount of nutrients in our waterways and leaves in storm drains. 

How WSB Can Help 

Not sure where to start with creating a targeted street sweeping plan? WSB can help create a customized street sweeping plan that meets your community’s needs. WSB can also help communities reach their pollutant removal goals and execute on water quality management.

Communities Can Prepare for Flooding and Build Resilience into Systems

By Jake Newhall, Project Manager, WSB

Extreme rainfall events are occurring with increased frequency. Due to climate and environmental changes, many cities and communities are facing an increased flood risk and must act to protect their communities, residents, and infrastructure. A 2019 report by the National Institute of Building Sciences noted that Natural hazard mitigation saves $6 for every $1 spent on infrastructure resilience.

How can community planners, engineers, and elected officials prepare for and protect their communities from flooding? Here are some guidelines to help reduce flood risk in your community when a storm hits.

Preparing for and Understanding the Weaknesses in Your Systems 

Flood vulnerability and resiliency studies are a process for evaluating a community’s ability to withstand rainfall and identify flood risk. These studies look at the existing systems and determine the risks, and where improvements can be made to protect priority infrastructure. This is vital for communities to reduce risks and flood damage to property and public infrastructure – especially in densely populated areas and those near major roadways. 

As we face more extreme weather events, communities should consider increased rainfall depths and intensities so they can be proactive in system planning. The current storm probabilities available have not been updated since 2014, yet rainfall trends show increases over the last decade. Communities can greatly benefit if they anticipate the future probabilities of storms and construct systems that can handle more intense rainfalls. Using a range of design storms, you can determine flood depths, frequency, duration and assign risk to help prioritize funding. 

Completing a risk analysis and inundation mapping utilizing existing modeling can be a low-cost way to start evaluating your system.

Identifying Projects to Reduce Flood Risk

Locating the areas of risk in your community is critical to flood prevention. That could include finding where your system needs more capacity and storage to reduce flooding, determine what properties are prone to flooding, and creating solutions such as relocation, emergency response, or additional flood protection investments. 

Where collected water goes is important when examining and determining updates for your systems. The primary options are to either pass the water downstream into creeks and rivers, or store it in drainage ponds, underground systems, or other storage areas. Another option is to reduce the impervious footprint to reduce the amount of runoff that is generated. Emerging technology allows for predictive rainfall systems that can generate additional storage ahead of a large rainfall event by releasing water early and prior to a peak event through a critical area.

The risk with moving the storm water downstream is the possibility of flooding and eroding the creeks and rivers. If conveyance capacity is increased to the downstream system, it is necessary to make sure that proper measures are taken to avoid flooding and erosion that can harm waters and ecosystems. Water storage options like drainage ponds or underground storage, are options for many communities to utilize. Balancing needs, functionality, and the cost of storage and land is important for communities to explore. Water quality and pollutant removals can be a secondary benefit of many stormwater storage systems that can help communities achieve other goals at the same time.  

Finally, for most communities, the needs often outweigh the budget available to accomplish them all. WSB helps clients navigate flood vulnerabilities, pursue grant funding, and help make informed decisions that best serve a community’s individual needs.

Water Sustainability and Community Planning

By Alyson Fauske, Sr Project Manager, WSB

Last summer, Minnesota experienced a drought due to above-average temperatures and below-average precipitation. This created a significant challenge for many community leaders and public agencies. To keep up with demand, wells were pumping at or near capacity over much of the summer, and communities were forced to implement water restrictions for the first time in decades. Some cities banned lawn sprinkling all together, though this is not water sustainability.

Heading into 2022, Minnesota is still facing drought conditions in some parts of the state. There are a number of things that communities and public agencies can do to plan for and respond to drought conditions using sustainable water planning.

Water Sustainability
The graphics above from the U.S. Drought Monitor track the progression of drought conditions beginning in June, 2021.

Limit Water Usage

In drought conditions, limiting water usage is critical and often the first step taken. Communities can help limit water use by developing water reuse systems and plans. They can also implement landscaping practices that require less watering including native plants and drought resistant plantings and grasses. Native plants also have the added benefit of supporting local wildlife health and helping to protect pollinator populations.

Tap Into Local Grants & Resources

In 2021, the Minnesota Department of Natural Resources (DNR) put together a Drought Assistance Proposal. This proposal includes a request for $13.3 million in funding to help cities address the effects of last year’s drought. WSB is tracking the funding package as it moves through the legislature and will be prepared to assist clients with grant applications for any approved funding, as well as identify other funding opportunities that are tied to this effort.

Long Term Water Sustainability

A significant portion of the budget for the Drought Assistance Proposal is set aside for proactive water conservation measures that would help combat the effects of potential future droughts.

Municipal engineering and sustainability go hand in hand. Municipal engineers develop plans and projects that maintain infrastructure, considering the whole life cycle of the project while aiming to minimize the amount the taxpayer needs to provide to routinely maintain the infrastructure.

Proactive water conservation measures allow communities to be better prepared for the next potential drought. These measures may consist of finding and repairing leaks, increasing irrigation efficiency, or incentivizing residential and business customers to install water-saving devices.

Climate change and a greater risk of drought impacts community planning, and leaders who implement sustainability measures that are proactive, and not just reactive to an immediate crisis, will fare better in managing drought.

How the DNR’s flood risk review could affect Minnesota communities

By Earth Evans, Director of Water Resources, WSB

The Minnesota Department of Natural Resources (DNR), in coordination with local watershed districts, has developed updated draft Federal Emergency Management Agency (FEMA) flood risk maps and hydrologic and hydraulic analysis. The affected area includes the floodplains in the hydrologic unit code 8 (HUC8) subbasin. HUC8 includes portions of Ramsey, Washington, Anoka, and Hennepin Counties.

The updated hydrologic and hydraulic analysis is based on National Oceanic and Atmospheric Administration (NOAA) Atlas 14 precipitation events across the United States. The draft flood hazard maps may expand existing FEMA regulated floodplains within the Twin Cities metro due to the higher precipitation depth and frequency. The FEMA map updates will likely take effect in 2023. This is the first step in the process to develop updated FEMA Flood Insurance Rate Maps.

It is important that city officials pay close attention to these updates. The draft FEMA floodplain boundaries may increase with this analysis, which may reduce developable area in a municipality, increase the number of properties that are required to purchase flood insurance, and require property owners to change the type of flood insurance they possess. Additionally, the DNR is requiring that each community update their ordinance to require mitigation for fill in the modeled storage areas upstream of FEMA floodplains. 

Currently, the maps are for city officials only. City staff should cultivate a strong understanding of the implications now, before the maps become open for public comment. During the next month, there will be opportunities for city staff to connect with the DNR staff, review floodplain limits, and understand the implications on developable area and properties that will require flood insurance within the community. 

WSB can help navigate this process and facilitate meetings with DNR Floodplain Staff. City officials are encouraged to reach out to Earth Evans, WSB’s Director of Water Resources with questions.

Simplifying MS4 compliance through technology

By Jake Newhall, Project Manager, WSB

Minnesota’s Municipal Separate Storm Sewer System (MS4s) are currently in the process of applying for coverage under the revised MS4 General Permit. The updated MS4 General Permit creates changes in the ways that MS4 permittees will operate, starting with modifications that address procedural and programmatic changes needed to comply with updated rules. 

One of the main changes is new performance-based responses to Total Suspended Solids (TSS) and Total Phosphorus (TP); including a TMDL assessment to identify and prioritize activities to achieve reductions. WSB’s SWAMP system helps to address these new regulations by streamlining TMDL compliance through tracking and documenting improvements that have been completed to date or since the baseline of TMDL development. The SWAMP system also helps target subwatersheds that are underperforming or lacking the necessary treatment to meet water quality goals. SWAMP improves efficiency by saving time on planning and modeling when developing an efficient plan to address TMDL requirements.

Aside from improving compliance with new MS4 TMDL requirements, SWAMP continues to help address existing MS4 requirements.

  • Estimate TP and TSS reduction from existing ponds and BMPs
  • Prioritize inspection and maintenance activities related to ponds and BMPs
    • Ensure standard operating procedures are in place and stormwater management features continue to function as designed
  • Inspection and maintenance activities are automatically updated and reflect real-time information
  • Tracks and stores completed activity records for on-demand reporting
