Traditionally, the construction of a soakaway has involved digging a hole and filling it with debris, limiting the amount of rainwater that can be collected. However, newer designs make use of plastic crates that leave the space completely open, allowing the rainwater to be collected to its full capacity. The crates can be two or three deep, and are assembled using a digger.

BS 6297: 2007 requirements for a soakaway

In the UK, the regulations relating to soakaway drainfields have changed over recent years. It is now mandatory for a soakaway drainfield to comply with the General Binding Rules and obtain an Environment Agency Permit. These rules govern how much wastewater may be discharged to the soil per day. The maximum permitted discharge is 2000 litres per day, which is equivalent to the discharge of around thirteen people. If the effluent reaches this level, it is illegal to use the soakaway drainfield.

A soakaway must be constructed in accordance with the requirements of BS 6297: 2007. This new code of practice gives recommendations for preliminary planning, detailed site investigation, system design and layout, and percolation tests. It also provides guidelines on how to determine the area of the trench.

The length of a soakaway drainage field drain depends on the number of bedrooms and the porosity of the soil. In a three-bedroom house, the minimum size of a soakaway drainage field drain must be 50 metres, while for a five-bedroom house, it should be 25 metres.

The requirements for a soakaway in the UK are outlined in the BS 6297:2007 standard. In accordance with these standards, drainage mounds must not discharge sewage into floodplains. If a soakaway is not constructed in accordance with these standards, a regulated water company will not allow it to discharge its waste into the surrounding land.

Problems caused by anaerobic bacteria in septic tanks

Anaerobic bacteria thrive in an oxygen-free environment. They are slower, harder workers than aerobic bacteria, and they break down solid waste. They are also responsible for creating a biomat around drainfield pipes, which aids in the purification of effluent as it passes through. When anaerobic bacteria are overly abundant in a septic tank, it can compromise the process.

Anaerobic bacteria are not as efficient at breaking down organic waste. This is why regular septic tank pumping is so important. Pumping will keep the bacterial colony balanced and ensure that the waste is properly broken down. You can also use a septic tank cleaner containing beneficial bacteria to boost the natural bacterial colony and improve the efficiency of the system.

Anaerobic bacteria are the most common type of bacteria in septic systems. They work together to break down waste and make a biomat, a layer of bacteria, around the drainfield. These bacteria then excrete the solid waste and turn it into benign effluent.

The anaerobic bacteria in a septic tank are responsible for reducing the volume of solid waste in the tank. This process leaves less room for new waste, and it results in a sludge layer at the bottom of the tank. The more sludge builds up, the greater the chances of a septic tank backup. Regular pumping will reduce the risk of backups.

Alternatives to a soakaway

A soakaway can be installed under your driveway or garden so that water can run off in the event of a rainstorm. It should be installed before your driveway is resurfaced or your garden is landscaped. The installation process can be costly, but there are some ways to reduce the cost. For example, you can get quotes from various companies on a comparison site, such as HouseholdQuotes.

Soakaways are designed to collect a large volume of surface rainwater that would otherwise be discharged into the sewers or a lake. If they weren’t in place, homes would be subject to flash floods during rainy days. To avoid this, rainwater from your roof gutters and driveway should be directed to a soakaway within the boundaries of your property. While installing a soakaway is highly recommended, you have other options. Please note that this article is meant to provide information about these alternatives, and is not intended to be a substitute for official regulations.

In addition to avoiding costly repairs and replacing a soakaway, you can also take advantage of rebate schemes from your local sewerage company. These rebates are given for people who meet certain criteria. However, you will need to check with your sewerage company to determine what rebate level they will grant you.
