ECO's Civil engineering work has included storm water mitigation systems. This covers residential and commercial surface drainage and detention systems, underground storm water storage systems, black and gray water separation systems, foundation flood vent engineered design, and sanitary/storm water line extensions.
ECO also provides flood plain evaluations, drainage evaluations, flood conveyance letters, and no drainage requirement certification letters.
Storm Water management expertise includes all aspects of a building's site project drainage evaluation for feasibility and planning, conceptual design, and site specific design.
We have provided both residential and commercial projects with foundation floodwater vent design, floodwater conveyance letters, floodwater detention surface pond designs. In addition to convention surface pond detention storage, ECO has specified and designed projects with the latest innovations of new underground floodwater storage systems. This photo shows the 'Atlantis' underground module system that can support a parking lot or street traffic on top.
'Green' flood water mitigation project under way - A green building engineered by ECO that is now under construction will include both primary and secondary storm water detention plus rainwater harvesting retention. The primary detention met Harris County's 100 Year Flood Event with a 24800 cf storm water detention pond connected to parking runoff with 150' French drain supply lines. This was connected to the building's downspouts. The detention pond is covered with and assortment of annual Texas wildflowers. Storm water outflow is by 300' of pipe with flow restrictor. A rain water harvesting cistern retention provided (2) 1000 gallon Optional Pioneer-Water rainwater cisterns are fed by roof down spouts. These rainwater tanks overflowed into a secondary detention 3722 cf volume provided by a 65.2'x41.5' Atlantis Underground Raintank module storage, which is outflow connected to the storm ditch by 150' of 12" pipe. Additional detention was provided by the storm drain piping (480 cf). The detention volumes were designed with return flow restrictors to drain over a 48 hours period following a 100 year flood event.
RAIN WATER HARVESTING: Although it can not be used as a floodwater mitigation system, ECO has also provided rainwater havesting consulting and design solutions such as this attractive urban cistern for several completed US Green Building Council 'LEED Certified' projects.
If you've read this far you are either really interested in ECO's Civil Services, or you are a competitor checking up on us. Here is ECO's latest step to support sustainability-
To further improve all projects we support, ECO has expanded of our civil engineering services to include Sustainable Civil BIM based design engineering services.
ECO-CIVIL sustainable design will push project land use, drainage design, site design, and utility designs to help reduce each project’s impact on water infrastructures, while reduce operating costs, water consumption, and waste water production.
BIM (Building Information Modeling) has become a shorthand phrase covering a medley of techniques that help predict project performance costs and impact before construction. BIM will be extended into ECO’s civil work through use of Revit MEP and AutoCAD.
Civil BIM helps predict the outcome and environmental impact of land development before the projects are built. By creating coordinated, reliable design information, ECO will be able to respond to project changes earlier, faster, and with less change order cost. ECO will optimize designs with analysis, simulation, and visualization; and more quickly deliver higher-quality designs and construction documentation.
BIM also enables a project team to extract civil data from the Civil model, facilitating earlier grading decisions, less costly & more sustainable drainage designs. And faster and more economic final project delivery. ECO’s BIM approach can provide a conceptual feasibility assessment that includes earlier value engineering. After team review the concept can move more quickly into detailed plan preparation. BIM then allows detail changes to design drawings to quickly and automatically update required report data for efficient implementation of the final adopted plan.
