No: 90 to 95% runoff from hard surfaces above system; 5-10% loss to runoff and conveyance. Does not promote groundwater recharge
No: Pre-treatment (e.g., vegetated filter strip, swale, turf grass, forebay) and post-treatment is required in most cases
No: Construction liability, product insurance, obtain confined space permits for inspections, use personal protective equipment
No: Requires extensive excavation. Chambers must be fabricated, shipped, and installed. Requires several components and third-party filtration. Up to 33% of disturbed volume not used for storage
Optimizing Land Use
Combine the parking and drive aisles with the retention or detention footprint: The area of your site that would otherwise be consumed by the pond to be transformed into a sustainable landscape with continuous use green space, recreational areas, or even reclaimed for increased development.
In conventional stormwater drainage designs, on-site detention or retention ponds can consume a large portion of the site. These ponds have limited alternative applications (assuming the pond dries out sufficiently for the intended alternative use) and reduce the income-generating footprint of the site. TRUEGRID allows you to reclaim the surface for full use in parking, roadways, or revenue generating leasing.
PRO PLUS® The Commercial Paver
TRUEGRID® Pro Plus is 100% permeable. Drive on the surface,
detain storm water below. Save land and money. Utilize 100% of your land by eliminating detention ponds.
Our products are also strong enough for heavy traffic or 18 wheelers, and they’re less expensive than concrete. The innovative design of PRO PLUS keeps the aggregate in place. Contained aggregate will not shift or pulverize and will not produce dust.
With the water detention/retention located within the TRUEGRID system, we eliminate public safety concerns associated with the accidental drowning of children, and do not provide breeding grounds for insects that transmit diseases like West Nile Virus. Harmful algal blooms will not contaminate the air surrounding a TRUEGRID install.
TRUEGRID is The World's Strongest Permeable Paver and will not collapse. Our sub-base is engineered from solid #57 stone or other engineered structural bases. Made from 100% recycled HDPE plastic, TRUEGRID is inert and resistant to chemicals.
Underground chambers, pipes, and tanks are vulnerable to static and dynamic forces from hydraulic stresses, traffic pressure, and soil-side loads. These forces act on both the underground systems themselves and the installed components required for them to function. Depending on the material composition, underground chambers are also subject to deterioration from salts, carbonation, lawn chemicals, and rust.
Your options are: expansive detention ponds, underground chamber systems or TRUEGRID. Here’s why TRUEGRID wins.
Above ground detention ponds require land... a lot of land. There are also safety concerns, expensive maintenance issues, and efficiency issues.
Underground stormwater systems like pipe, modular chambers, and other tank systems are expensive to install, treat, and maintain. At nearly the same volume of excavated area, you can accomplish all your stormwater storage needs with TRUEGRID at a fraction of the installed and life-cycle costs.
TRUEGRID requires very little maintenance especially compared to detention ponds and underground systems. TRUEGRID is more efficient: 100% permeability means virtually no water loss to runoff, evaporation, or conveyance. All the pollutant removal and filtering is done within TRUEGRID's cross-section; Underground chambers and above ground ponds require expensive filters and separators to function. TRUEGRID requires no added curbing, strip drains, grates, conveyance pipes, manholes, or liners -- A majority of which are required, in some combination, by ponds and underground chambers.
Start saving money, time, and maintenance by designing and specifying TRUEGRID for your stormwater detention and retention needs.
The owner of this self-storage facility was about to develop his site. His engineers, as well as the city, told him he would need to use 2.5 acres of his 14-acre site to build a detention pond. Gravel alone would not be counted as pervious cover.Read Story
