Andover sits just west of the Lakes Region proper — Highland Lake, Proctor Academy, and rural roads running toward Ragged Mountain. The town has no municipal sewer; village and countryside alike run on private systems.
Highland Lake gives Andover its own version of the camp-conversion story — cottages ringing the lake that started as summer places and became homes — while the town's older village housing and outlying farms carry systems of every vintage. Andover's sandy-gravel soils in the valleys are kind to leach fields; the ledgier ground toward the mountains is less so, and knowing which your lot sits on shapes every repair-or-replace decision.
Highland Lake owners: same rule as every NH lake — protected shoreland waterfront requires a septic site assessment at sale. Order it early and closing stays on schedule.
Routine pump-outs with filter rinse and baffle check. Most tanks $300–$500.
Baffles, lines, distribution boxes, and honest leach field diagnosis.
Pump-and-inspect evaluations and shoreland site assessments with 48-hour reports.
Same-day pumping when the system backs up.
Same-week scheduling, straight prices, and answers before the truck rolls.
