The AquaLogic system allows the following methods of lease, sale and maintenance:

• Lease (includes AquaLogic maintenance)
• Purchase with Owner-provided maintenance
• Purchase with AquaLogic-provided maintenance

There are numerous benefits to both owners and developers when implementing the AquaLogic stormwater abatement filtration system compared to sand filter basins for treating stormwater runoff:

• Applying the requirements in TCEQ Technical Guidance manual RG-348 results in the AquaLogic basin having a reduced basin size of approximately 30 to 45 percent when compared to a sand filter basin handling the same water volume
• The smaller required size of the AquaLogic basin results in a reduced initial construction cost when compared to a sand filter basin
• TCEQ-documented total suspended solid (TSS) removal efficiency is greater than the removal efficiency for a sand filter basin (95 vs. 89)
• The AquaLogic design methodology and size results in added flexibility of land use
• Because an AquaLogic basin requires less volume than a sand filter basin based on the TCEQ design guidelines, the option exists to convert an earlier designed sand filter basin to an AquaLogic basin thereby increasing the available impervious area on a property without the need to increase the size of the storm water filtration basin, or the need to add an additional basin
• The TCEQ design guidelines do not require an access ramp into the AquaLogic basin due to the ability to manually perform maintenance without the need for heavy construction equipment; TCEQ guidelines require access ramps for sand filter basins
• The TCEQ design guidelines do not require the designer provide a maintenance staging area for AquaLogic basins, whereas they require an 800 square foot staging area for sand filter basins because of the same general need to periodically perform maintenance with heavy construction equipment
• For this same reason, the TCEQ guidelines only require a minimum 8 foot wide maintenance access road for AquaLogic basins, whereas they require a 12 foot wide access road for sand filter basins
• The AquaLogic design methodology allows it to be functionally place underground thereby providing additional usable surface landscaping and/or parking space
• The ease of maintenance of the AquaLogic basin results in reduced annual maintenance cost when compared to a sand filter basin
• The AquaLogic design methodology results in reduced health and public safety risks when compared to a sand filter basin

Examples:

Plaza Las Campanas:

• 44 percent reduction in size compared to original sand basin design
• Preservation of natural eco-area for staging and/or future utilization
• Estimated construction cost savings of $278,000
