Septic Tanks & Water Treatment Plants

Septic tanks are a common choice for cottages and older homes around Oakley or Overton, as they require minimal power and maintenance. However, UK regulations now often favour sewage treatment plants for new installations.

Treatment plants offer improved water quality and are necessary where stricter environmental rules apply, such as near Tadley or Whitchurch.

Tanks in Hampshire usually need emptying every 12 months, though usage and tank size affect this. Regular emptying avoids solids entering the soakaway and causing expensive failures.

Our crews use specialist tankers to safely remove waste and clean the tank’s interior. All waste is taken to licensed treatment facilities.

Mechanical treatment plants must be serviced regularly to keep pumps and aerators working efficiently. Neglected units may alarm or discharge untreated water.

We inspect all moving parts, clean the system, check electrical connections and replace worn components. Most manufacturers recommend annual servicing for compliance.

Blocked or overflowing septic tanks often need urgent attention, especially after storms or heavy use. Property owners near Hook or Chineham sometimes notice sewage backing up or pooling outside.

We offer 24/7 emergency cover with a one-hour response target, ensuring prompt waste removal to prevent damage or health risks.

A sewage treatment plant is a mechanical system that treats household waste water more thoroughly than a traditional septic tank. These units often use blowers or rotating discs to break down pollutants.

Treated water is cleaner and can usually be discharged directly to a watercourse or drainage field, making them popular for properties near streams or clay soils.

Installing a septic tank involves excavation, correct siting away from buildings and water sources, and setting up inlet and outlet pipework. Drains are carefully routed to prevent leaks.

Basingstoke Drains handles the full process, including system design, notifying building control, and commissioning. Advice is given on the type and size required for your property.

Common septic tank problems include cracked concrete, failed baffles, or broken inlet pipes. Early signs are slow drains or sewage smells in the garden.

Repairs may involve excavation, patching cracks, replacing pipework, or fitting new covers. We provide written quotes and guarantee all repair work.

Environmental rules in Hampshire require septic systems and sewage plants to meet strict discharge standards. Permits may be needed if draining to a stream or ditch.

We help customers navigate Environment Agency requirements, offering advice on necessary upgrades, permits or changes. This helps protect local watercourses and gardens.

Your drainage field (or soakaway) is vital for dispersing treated water. Problems like saturated soil, root intrusion, or damage from vehicles cause backups and tank failures.

We use CCTV and pressure testing to assess field condition, recommending repairs or replacement if necessary. Correct maintenance extends the life of your septic system.
