GeoRidge™

Durable, low cost GeoRidge™ berms are designed to provide effective erosion and sediment control. GeoRidge™ is portable, lightweight, stackable and proven to be an effective energy dissipater. Designed to replace rock and straw bale check dams. Rather than totally blocking the flow, GeoRidge™ reduces the flow velocities and provides a smoother, less damaging release of water - eliminating the problem of downstream sediment. GeoRidge™ is quick and easy to install, with no machine trenching required. A simple anchoring system is used to secure the panels on both the upstream and downstream sides, usually in minutes. Application of an erosion control blanket is recommended for under the GeoRidge™ panels. The blanket will prevent undermining of the panels and encourage the best possible vegetation growth.

Advantages

  • Constructed of a UV stabilized HDPE
  • Lightweight - about 2.2 lbs.
  • Reusable
  • Portable and stackable - 500 GeoRidge™ can easily fit on a pickup truck
  • Quick and easy installation
  • No machine trenching required
  • Simple anchoring system
  • Minimum maintenance
  • Collects sediment and debris
  • Reduces rather than blocks flow velocities
  • Open structure allows revegetation
  • Complements the performance or erosion control blankets

 

The Pondless™ Waterfall

Using an Aquascape Designs MicroSnorkel™ Vault and MicroCentipede™ Module allows for creation of a waterfall and stream without a pond. Instead, a basin is excavated, lined with an EPDM liner and filled with layers of stone. Once the basin is filled with water, the water flows through the MicroCentipede™ Module and is circulated by a pump that sits at the bottom of the MicroSnorkle™ Vault up to the BIOFALLS™ filter. The BIOFALLS™ filter then returns the water to the basin, via waterfall and stream. Since the water level remains below the rock and gravel fill, it gives the appearance of a "pondless" waterfall and stream, yet provides plenty of water to run the system.

System Attributes:

  • Great for customers who do not want a pond, just a waterfall and stream.
  • Perfect for public settings where child safety and liabilities of a pond may be a concern.
  • Virtually maintenance free! Simply refill the reservoir every few weeks or add a water fill valve to the Snorkle™ Vault to compensate for water loss due to evaporation.
  • Great alternative for a front yard pond.

Custom Pondless™ Waterfall Kit should include the following:

  • BIOFALL™ filter-sized for the project
  • MicroSnorkel™ Vault & Cap
  • MicroCentipede™ Module
  • Aquascape Pump - sized for the project
  • Dual Union Check Valve
  • 2" PVC Flex Pipe
  • Installation Kit
  • Stream and Basin Liner - sized for the project
  • Underlayment
  • Light Kit

EPA Storm Water Phase II Rule

The Clean Water Act of 1972 prohibited the discharge of any pollution to navigable waters of the United States from a point source unless the discharge was authorized.

In order to discharge any pollutant, you are required to obtain a National Pollutant Disclosure Elimination System (NPDES) permit. As time went on it became apparent that a major source of that pollution was from soil erosion coming directly from industrial, commercial, and residential construction sites.

In 1990, Phase I of the U.S. Environmental Protection Agency's (EPA) storm water program established rules regulating, among other discharges, pollutant and storm water runoff from large construction sites that disturbed 5 acres or more of land. It was later determined that smaller sites created an equally high pollution impact. Phase II became enforceable by state and local agencies with consent from the EPA on March 10, 2003, and it extends coverage to construction activities disturbing between 1 and 5 acres of land, or that are within 500 feet of a lake or stream. These rules require operators of construction sites to obtain NPDES permits and implement "Best Management Practices (BMPs)" to minimize pollutant runoff.

Today, enforcement of the permitting requirements and the instituting of severe fines for non-compliance are commonplace. Even if your site is less than 1 acre, a permit could be required if it is part of a larger site. Complying with the permit process and utilizing storm water BMPs actually can save you money - not cost you money!

CSI Geoturf can provide you the BMPs and technical assistance necessary to keep you in compliance. Call the location nearest you for answers to your Phase II questions or for a list of our training seminars and dates.
