Erosion and sediment control

Stormwater permits expect soil to stay on your site. We source silt fence, inlet protection, wattles and stabilized entrances from local providers in the markets we serve, and schedule them with your toilets, washout and containers. Availability varies by market.

What it is

Two jobs: hold the soil, catch what moves

Erosion controls keep soil in place, with cover and stabilization. Sediment controls catch the soil that moves before it leaves the site or reaches a drain. Most sites need both, and the stormwater plan says which go where.

Common controls

  1. Silt fenceFabric on stakes along the downslope edge of disturbed ground, which holds back sediment while water passes.
  2. Fiber rolls and wattlesRolls of straw or other fiber staked along the contour, at the toe of a slope or around a stockpile.
  3. Inlet protectionFilters or barriers at storm drain inlets that remove sediment before stormwater goes in.
  4. Stabilized entranceStone over fabric at each exit, so trucks do not carry mud out. See wheel wash and track-out.

When a job needs it

When the site needs controls

Controls go in before the earthwork they protect, and stay until the ground is stable.

  1. 01

    Clearing, grading and digging

    Any time soil is exposed and rain can move it.

  2. 02

    Sites under a stormwater permit

    Under EPA's permit, sites that disturb one acre or more, or are part of a larger plan that will.

  3. 03

    Work near drains and water

    Storm drain inlets on or next to the site, or water within 50 feet of the disturbance.

  4. 04

    Stockpiles

    Soil and debris piles need a barrier on the downhill side, and cover when they sit unused.

The rules

What the construction stormwater permit requires

EPA's 2022 Construction General Permit applies where EPA is the permitting authority. Most states run their own permits with similar rules, so check yours.

CGP Part 2.2.3

Perimeter controls downslope

Install sediment controls along any perimeter downslope of exposed soil, such as silt fence, compost filter socks, filter berms or gravel barriers. Run them on the contour with the ends turned up the slope, and remove sediment before it reaches half the height of the control above ground.1

CGP Part 2.2.10

Protect storm drain inlets

Install inlet protection at inlets that carry your stormwater to a receiving water, where you have access, and clean or replace it as sediment builds up. Sediment next to an inlet comes out by the end of the same business day, or the next if that is not feasible.1

CGP Part 2.2.5

Barrier and cover stockpiles

Put a sediment barrier, such as fiber rolls, silt fence or sandbags, along the downhill side of soil and land clearing piles, and cover or stabilize piles that will sit unused for 14 days or more.1

CGP Parts 2.1.3 and 2.1.4

Install first, keep them working

Controls needed for the next phase go in before that earth disturbance starts. Routine maintenance starts right away and is finished by the close of the next business day, or within seven calendar days where that is infeasible and documented.1

Your stormwater plan decides which controls go where. We source local providers to supply and install them. See SWPPP site services.

Controls to install before grading?

Send us the plan and the dates. We source a local provider to supply and install the controls.

The options

Where each control goes

Each control has a place on the site and a way it fails. Inspections look for both.

ControlWhere it goesWatch for
Silt fenceThe downslope perimeter of disturbed groundUndercutting, and sediment past half its height
Fiber rolls or wattlesOn the contour, at slope toes and around stockpilesGaps between rolls and loose stakes
Inlet protectionStorm drain inlets on and next to the siteClogging, and sediment building up beside it
Stabilized entranceEvery exit onto a paved roadStone packed with mud, and tracking onto the street

How it works with Detritus

One request for the whole plan

You get one point of contact. A local provider supplies, installs and repairs the controls.

  1. You send us the plan

    The stormwater or erosion control plan, the site map and the phases.

  2. We source a local provider

    Materials and installation from a provider in your market, quoted with your other site services.

  3. Installation

    Controls go in before the earthwork they protect.

  4. Repairs

    After an inspection or a storm, call us and we schedule the provider to fix or replace controls.

  5. Removal

    Temporary controls come out once the site is stabilized.

For a quote

What to tell us

A plan sheet is the fastest way to a quote. Without one, these answers get us close.

  • The site address and how much ground will be disturbed
  • Your stormwater or erosion control plan and site map, if you have them
  • Linear feet of silt fence or wattles, if you know them
  • How many storm drain inlets need protection
  • How many exits open onto paved roads
  • The start date and the phases of earthwork
  • Who inspects the controls: your team or a third party

Common questions

Erosion control questions

What is the difference between erosion control and sediment control?

Erosion control keeps soil in place, for example with cover and stabilization. Sediment control catches soil that has moved, for example with silt fence, fiber rolls and inlet protection.

Do I need silt fence on my site?

If your site is covered by EPA's construction permit, it needs sediment controls along perimeters downslope of disturbed areas, and silt fence is one example. Your state permit may set its own rules.

What is inlet protection?

A filter or barrier at a storm drain inlet that removes sediment before stormwater goes into the drain.

When does sediment have to be removed from silt fence?

Under EPA's construction permit, before it reaches half of the above-ground height of the perimeter control. Repair any undercutting after a storm.

Can you supply wattles and inlet protection?

We source them through local providers in the markets we serve. Tell us the site and the plan.

How do I get a quote?

Call sales at (888) 588-2607 or request a quote with the address, the plan and the dates.

Erosion control on one agreement

Local providers do the work. We source them, schedule them with your toilets, washout and containers, and send one bill.
