Consistent and proper maintenance is the single most important factor for maximising the lifespan of your concrete tank.
Water Tank Maintenance
| Action | Frequency | Why It’s Critical |
| Full Inspection & Cleaning | Every 1–2 Years | Professionals should inspect for cracks/leaks, check fittings, remove sediment, and conduct a complete chlorine disinfection. |
| Visual Check | Monthly | Check the access lid for a tight seal, inspect the overflow and inlet screens, and look for any pooled water around the tank that might indicate a leak. |
| Test Water Quality | Annually (or after heavy rain) | Recommended to ensure the water is safe for its intended use, primarily if used for drinking. |
Important Cleaning Note: If cleaning the interior yourself, never enter the tank without confined space certification and proper safety equipment, as trapped gases or low oxygen levels pose a serious risk.
Septic Tank Maintenance
| Action | Frequency | Why It’s Critical |
| Professional Inspection | Every 3 Years | Check the sludge/scum layers and inspect baffles and electrical components (if applicable). |
| Tank Pumping (De-sludging) | Every 3–5 Years | Frequency depends on household size and tank volume. This prevents solids from overflowing into and clogging the delicate drain field. |
| Drain Field Protection | Daily | NEVER park or drive vehicles over the drain field. Avoid planting deep-rooted trees/shrubs nearby. Divert all gutter and storm water away from the area. |
Septic System Do’s and Don’ts:
| DO | DO NOT |
| Use water-efficient fixtures. | Flush non-biodegradable items (wipes, feminine hygiene products, cat litter). |
| Repair all leaky faucets and toilets immediately. | Pour grease, cooking oils, or large quantities of chemicals (paint, solvents, excessive bleach) down the drain. |
| Limit or eliminate the use of a garbage disposal. | Use septic tank additives (they are rarely necessary and can disrupt the bacterial balance). |
