Start With a System Assessment
Before performing any service, we identify system condition, risk level, and component health — so the right work gets done, not just reactive fixes. Most customers who start with an assessment avoid $3,000–$10,000 in reactive repair costs.
Our proprietary Blackwater System Health Score (BSHS) gives every system a 0–100 rating so you know exactly what you're dealing with — not just pass or fail.
Schedule Risk & Eligibility AssessmentSeptic Pumping & Pump Outs
Regular septic pump outs are the single most important thing you can do for your system. We recommend every 3–5 years depending on household size. Prevents costly drain field failure before it starts.
- Thorough tank inspection
- Complete solids removal (pump out)
- Filter cleaning
- Condition report provided
- Prevents drain field failure
Protection Plan members receive priority scheduling and discounted pump out rates.

We offer two inspection types: the Snapshot Inspection™ (county compliance pass/fail for home sales) and the Protection Inspection™ (full health scoring + BPP enrollment eligibility). Most homeowners benefit most from the Protection Inspection.
