Batch Detention
by TXRWS
Superior water quality performance over traditional detention basins
Reduced Construction Costs
Cost savings over sand filters results from smaller footprint and less dirt work
Use where land availability is restricted, less than 5 acres for below-grade install
Lower power requirements, solar power allows easy placement
High TSS removal rate–91%
Shape and Flow Flexibility
Batch detention ponds can be any shape and accept flow from any direction, does need costly splitter box typically used in sand filtration pond
Can function with little elevation head
Batch Detention Associated Costs
Less Expensive
Than sand filters, wet ponds, and created wetlands BMP’s
Largest Cost is Excavation
Using natural typography can significantly reduce cost-using a flood basin that already exists on the site can make the conversion to BMP structure extremely cost-effective rather than constructing a new pond.
Cost Savings
Over sand, filters derive from smaller footprint and reduced construction costs, no filtration media like gravel or sand, minimal maintenance costs
Using Solar Power
Reduced construction costs since an electrical circuit does not have to be installed all the way to a remote corner of the property where the batch pond is typically located. Solar power also does away with the need of a separate electric meter to power the system. This can be very useful if the pond is maintained by a subdivision, HOA, or is a regional pond that serves multiple lots.
More expensive than grassy swales and vegetated buffer strips, however
More Efficient
Design Criteria Overview
Capture and temporarily detain water quality volume with automated controller and valve
Primary function – settling basin. Downstream erosion can be limited by controlling peak flow rates when stacked with detention volume and outlet structure.
Solar power preferred by TCEQ
Can be readily combined with flood and erosion control detention basins by providing additional storage above the water quality volume

Controller Function
1
Valve is Closed
Default position is always closed. 1.5" of rain in pond triggers 12-hour timer
2
Valve Opens and Drains Pond
When 12-hour timer expires
3
Pond Empties
Within 48-hours or less after rain event ends
4
Valve Closes
When pond sensor switch detects no water, valve to be closed in 2-hours to let final drain happen
