Your on-site solids control and dewatering equipment and service provider.

S3S (Stage 3 Separation) separates solids from liquids for oil and gas drilling, construction and tunnelling, dredging, and industrial and municipal customers, and returns reusable water or base fluid along with dry, stackable solids.

Fred Lausen, Jr. founded S3S in 2009. Today hundreds of field technicians, supervisors, engineers, and scientists work from five locations: Houston, Midland, Calgary, Smithfield, and Mandan.

Fleet and field operations

Our fleet is large enough to size equipment to each job, and every unit is serviced on schedule with a service record available for review. Field operations run 24 hours a day, 7 days a week.

Lab analysis and job reporting

Our sample history informs the recommendation for each new program. During a job, crews adjust the system using flow, density, recovered volume, machine health, and chemical response data, then report the results to the customer.

Our core values

The same four values guide our office teams and field crews on every job.

01

Safety

Vibration sensors and remote monitoring track every machine’s performance. When a unit falls outside safe operating limits, our crews shut it down and replace it. Safe operation sets the limit, production never overrides it.

02

Innovation

Our in-house engineers turn project challenges into purpose-built equipment. When standard systems fall short, we design, fabricate, and deploy custom solutions, including one-of-a-kind systems built around your operation.

03

Integrity

We build trust with customers by communicating openly and honestly about our products and services.

04

Teamwork

Our field technicians, supervisors, engineers, and clients work as one team, carrying project knowledge from planning through execution. Consistent crews and hands-on leadership keep the people who scope the work closely involved in delivering it.
