What Does Algae Need to Grow?
As much as algae tend to take over everything from aquariums to natural lakes, it’s surprising that it needs any care at all to flourish.
Why Is It So Challenging to Grow Algae?
With so many promising uses for algae, it’s a wonder that the commercial algaculture industry is still relatively new and small.
The Potential of Large-Scale Algae Production
While algae have been cultured somewhat informally around the world for many centuries as a food or feed source, large scale commercial production is still relatively new.
Utilizing Undisturbed Areas in Stormwater Management
The preservation of undisturbed natural areas, as well as using them as buffers, is a principle that can be utilized.
Stormwater Management Feature Location Considerations
There are considerations that need to be made for a stormwater management plan, such as the best locations for your stormwater management features.
Permeable Pavement for Stormwater and Rain
Permeable pavement, also referred to as porous concrete or pervious concrete, is a highly porous pavement that allows rainwater to pass through it and soak into the ground beneath it.
Stormwater or Rainwater Art
Stormwater management is not always pretty. In fact, many times, drainage ditches, culverts, and black pipes can be an eyesore.
Impact Design Requirements of LID Stormwater Management
The main goal of low-impact design strategies is to distribute or scatter stormwater and urban runoff across developed sites.
Bioretention Basins and Retaining Ponds for Stormwater
Bioretention basins are another low-impact development strategy.
The Growing Value of Building New Greenhouses at State Prisons
State prisons across the country are focusing on ways to improve and reform the correctional experience, both for the benefit of the prison population and the community around each facility.
Catch Basins for Stormwater
A catch basin, also known as a storm drain, is used to redirect water to prevent flooding.
Water Harvesting Stormwater
Water harvesting, a LID strategy, is the collection and storage of rainwater.
What are Disconnected Downspouts?
Downspout disconnection is a LID strategy that separates roof downspouts from their previous normal route – a piped system that enters the sanitary sewer system and/or discharges it onto impervious surfaces.
Rain Gardens and Bioretention Areas
A rain garden, one example of a low-impact development strategy, is a planted shallow depression (the catchment area).
Stormwater Use for Green Roofs / Vegetated Rooftops / Living Roof
A green roof, a low impact development (LID) strategy, is an alternate roof surface that is partially or completely covered with vegetation.
Low-Impact Development Stormwater Management Strategies
According to the United States Environmental Protection Agency, the term low impact development refers to “systems and practices that use or mimic natural processes that result in the infiltration, evapotranspiration or use of stormwater in order to protect water quality and associated aquatic habitat.”
Stormwater Management in Urban Settings
Historically, stormwater strategies have included methods to collect, store and move runoff away from urban environments into nearby waterways to prevent flooding in the cities.
What are Floodplains?
Floodplains vary in size and consist of the floodway -- the main channel of the river or stream -- and the flood fringe which extends from the outer banks of the floodway to the enclosing valley walls.
Managing Stormwater in the City
Although cities afford untold opportunities to the human race, the development that goes with them tends to cause problems when it comes to runoff management.
What is Stormwater Management?
Stormwater runoff is generated when natural precipitation – rain, snow, ice melt, etc. – does not initially infiltrate/percolate into the ground.
Retrofitting Older Ponds and Raceways with New Liners
There are hundreds of aging and old hatcheries around the country that must shrink their production goals each year as individual tanks and ponds are shut down for leaking and water quality issues.
To Drain or Not to Drain Hatchery Ponds
Hatchery ponds, much like any intensive fish farming pond, are unique in that they are regularly, completely harvested.
Choosing a Flexible Liner for Fish Hatchery Uses
It’s clear that flexible liners have an important role to play in the modern hatchery, whether it’s for lining a ditch to prevent runoff from ruining water quality or for protecting an in-ground pond.
