Permian Basin Oilfield Sanitation Checklist

Use this checklist before a rig move, frac job or pipeline spread to get the right restrooms on site and keep them serviced.

Key takeaways
  • A pad-site restroom order should include the crew count per shift, the number of shifts, the GPS pin, the lease name, gate combos, any cattle guards, the start date and the billing reference such as an AFE number.
  • A frac or drilling crew needs at least 1 toilet for 20 or fewer workers under OSHA 1926.51, and 1 seat plus 1 urinal per 40 workers above that.
  • Keep units standing by staking or strapping them, placing them beside a trailer or tank battery, and turning doors away from the wind.
  • The rental company is responsible for hauling and disposing of the waste.

What should a pad-site restroom order include?

A pad-site restroom order should include the crew count per shift, the number of shifts, the GPS pin, the lease name, gate combos, any cattle guards, the start date and the billing reference such as an AFE number. Those details cut delivery time on lease roads.

  • Crew count per shift and number of shifts
  • GPS pin and lease road directions
  • Gate combo and cattle guards
  • Start date and expected length
  • Billing reference (AFE, well name, PO)

How many units does a frac or drilling crew need?

A frac or drilling crew needs at least 1 toilet for 20 or fewer workers under OSHA 1926.51, and 1 seat plus 1 urinal per 40 workers above that. With 24-hour shifts, we recommend 1 unit per 10 workers per shift and twice-weekly service.

How do you keep units standing in West Texas wind?

Keep units standing by staking or strapping them, placing them beside a trailer or tank battery, and turning doors away from the wind. NWS Midland recorded a 63 mph gust in March 2019. Open pads are the most exposed.

Who is responsible for the waste?

The rental company is responsible for hauling and disposing of the waste. In Texas, haulers of chemical toilet waste must register with TCEQ under 30 TAC Chapter 312. Ask any vendor for its registration.

Related questions

Our dispatchers hear these 3 questions often, including “How many porta potties does my crew need?” and “How will the driver find the spot? GPS always sends people to my neighbor.?” The answers are written the way we explain them on calls. Starting prices appear only here, and your itemized quote confirms the exact total.

How many porta potties does my crew need?

OSHA requires at least 1 toilet for 20 or fewer workers. Over 20 workers, the rule is 1 toilet seat and 1 urinal per 40 workers. We recommend 1 unit per 10 workers with weekly service, so tanks and paper last the full week.

How will the driver find the spot? GPS always sends people to my neighbor.

Tell us when you book and we will add a note to the order. You can also text a pin drop or photo of the exact spot. For ranches, lease roads and pad sites, GPS coordinates work best.

Can you direct-bill us? We're a business or government agency.

Yes. Businesses and agencies can apply for net-30 billing. Approval usually takes 1 to 2 business days. Government and tax-exempt buyers should send a tax-exemption certificate with the order.
