* Sandbags (Standard Construction Detail #3-15), Jersey barriers (Figure 3.13) or other non-erosive material, no earth fill. Do not excavate a sump for the pump intake.

** See Standard Construction Detail # 4-14. For low gradient channels, the rock filter may be replaced by an impervious cofferdam to prevent backflow into the work area.

NOTE: Pump intake shall be maintained a sufficient distance from bottom to prevent sediment from entering the system.

DEWATERING WORK AREAS - Wherever water is pumped from a disturbed area, it must be treated for sediment removal prior to discharging to a surface water unless it can be shown that the quality of the water being pumped already meets discharge standards. If a properly functioning sediment basin or sediment trap is available, the pump discharge may be routed through the trap or basin. While pumping, the maximum water level in the trap or basin should not exceed the cleanout elevation.

Water pumped from disturbed areas may not be discharged directly to detention ponds, since they are not designed to be efficient sediment removal structures. Straw bale structures and filter fabric structures are not acceptable for filtering pumped water due to their history of ineffectiveness. Filter bags, as shown in Standard Construction Detail #3-16, and Sump Pits, as shown in Standard Construction Detail #3-17, may be used to filter pumped water as described in the following section.

Other devices for filtering water pumped from excavations will be reviewed on a case-by-case basis.

The topography and conditions of the ground cover between the discharge point and the receiving surface water should be evaluated for potential erosion. Appropriate stabilization measures should be incorporated where needed to prevent erosion.

No filtering device is required for water pumped directly from a stream channel as part of a pump-around bypass system.

PUMPED WATER FILTER BAG - Sediment Removal Efficiency: LOW. This device is not an ABACT for special protection watersheds unless surrounded by a compost sock ring or operated in conjunction with a sump pit. Filter bags may be used to filter water pumped from disturbed areas prior to discharging to surface waters. They may also be used to filter water pumped from the sediment storage areas of sediment basins and sediment traps.

Northampton County Conservation District

The maximum pumping rate for any bag in use or proposed for use on a site should be available at the site at all times during pumping operations. Pumping rates will vary depending on the size of the filter bag, and the type and amount of sediment discharged to the bag.

Filter bags should be installed according to the details shown in Standard Construction Detail #3-16.

STANDARD CONSTRUCTION DETAIL # 3-16

Pumped Water Filter Bag

Low volume filter bags shall be made from non-woven geotextile material sewn with high than 150 microns. High volume filter bags shall be made from woven geotextiles that meet the following standards:

Property Test Method Minimum Standard Avg. Wide Width Strength ASTM D-4884 60 lb/in

Grab Tensile ASTM D-4632 205 lb Puncture ASTM D-4833 110 lb

Mullen Burst ASTM D-3786 350 psi UV Resistance ASTM D-4355 70%

AOS % Retained ASTM D-4751 80 Sieve

A suitable means of accessing the bag with machinery required for disposal purposes shall be provided. Filter bags shall be replaced when they become ½ full of sediment. Spare bags shall be kept available for replacement of those that have failed or are filled. Bags shall be placed on straps to facilitate removal unless bags come with lifting straps already attached.

Bags shall be located in well-vegetated (grassy) area, and discharge onto stable, erosion resistant areas. Where this is not possible, a geotextile underlayment and flow path shall be provided. Bags may be placed on filter stone to increase discharge capacity. Bags shall not be placed on slopes greater than 5%. For slopes exceeding 5%, clean rock or other non-erodible and non-polluting material may be placed under the bag to reduce slope steepness.

No downslope sediment barrier is required for most installations. Compost berm or compost filter sock shall be installed below bags located in HQ or EV watersheds, within 50 feet of any receiving surface water or where grassy area is not available.

(Additional Notes for Standard Construction Detail # 3-16)

The pump discharge hose shall be inserted into the bags in the manner specified by the manufacturer and securely clamped. A piece of PVC pipe is recommended for this purpose.

The pumping rate shall be no greater than 750 gpm or ½ the maximum specified by the manufacturer, whichever is less. Pump intakes shall be floating and screened.

Filter bags shall be inspected daily. If any problem is detected, pumping shall cease immediately and not resume until the problem is corrected.

SUMP PIT - Sediment Removal Efficiency: LOW. This device is not an ABACT for special protection watersheds unless used in conjunction with a pumped water filter bag. For sites where large volumes of water of low to moderate turbidity (i.e. not flowing from or through work areas) must be pumped from work areas, and many filter bags would be required, sump pits (Standard Construction Detail #3-17) can provide a means of filtering the water. They may also be used in conjunction with filter bags to reduce the amount of sediment being pumped into the bags, reducing the number of bags required. Sump pits used in conjunction with filter bags may also be used as an ABACT BMP in special protection watersheds. Sump pits should not be used alone where highly turbid waters are being pumped such as typically results from active work areas.

Sump pits should be located at a low point in the work area so that the water naturally drains toward the pit. The size of the pit required depends upon the amount of water that must be pumped from the work area and the space available.

When used in conjunction with a filter bag, the intake of the pump going to the filter bag should be inserted into the standpipe of the sump pit.
