Why Your Cistern Needs Regular Cleaning & Inspection

Over time, sediment, bacteria, and debris naturally build up inside your cistern. Even sealed systems collect dirt, rust particles, and organic material that can affect water quality.

Well-fed tanks are especially prone to sediment buildup, as minerals, sand, and naturally occurring contaminants from the well settle at the bottom of the tank. Without regular cleaning, this accumulation can lead to odor, discoloration, reduced water quality, pump strain, and costly repairs.

Seals and gaskets can fail over time due to age, temperature changes, ground movement, and normal wear. If water levels drop below the main seal, the gasket can dry out and shrink. Once a seal loses flexibility, it may crack or fail—allowing contaminants in and water to leak out.

Lids, risers, and fill pipes can also become problem areas. Loose-fitting lids, deteriorated riser seals, cracked fittings, or improperly sealed fill pipes can allow surface water, insects, rodents, dust, and debris to enter the tank. In colder climates, freeze-thaw cycles can shift components and weaken connections, increasing the risk of leaks and contamination.

Small cracks, worn seals, or failing connections can cause you to lose water without realizing it, leading to higher hauling costs, increased well run time, or unexplained drops in tank levels.

Routine cleaning and inspection help identify these issues early—protecting your water, your system, and your investment.

Keep your cistern clean, sealed, and reliable year-round.
