Soakaways are a type of sustainable urban drainage system that collects runoff from a new development. They are designed to be easy to maintain and do not interfere with the foundations of a building. There are specific requirements for soakaway siting, depending on the geological conditions of the site and local planning regulations. If you are considering having a soakaway installed, you should contact your local planning authority for more information.
SUDS – Sustainable urban drainage systems
The design of a sustainable drainage system (SUDS) must be compatible with the natural processes of water. The SUDS approach is part of green infrastructure. Its implementation will help cities reduce flooding and promote a more sustainable community. In addition, it will be compatible with existing infrastructure such as the sewer system and water treatment facilities.
SUDS can be achieved through the creation of retention ponds that can store water during periods of dry weather. Another type of SUDS is the creation of wetlands. Wetlands are vegetated areas containing shallow ponds and marshland. In order to install a SuDS, a proposal must be submitted to a local planning authority. Many authorities will also require a flood risk and drainage assessment.
Sustainable drainage systems can mimic natural drainage processes to reduce surface water flooding and improve water quality. They can also benefit local biodiversity. Early consideration of SUDS can ensure the best results. SuDS can also free up capacity in existing drainage networks. This may be the reason why SuDS can be a planning requirement in some cities.
Cost of a Soakaway
A Soakaway is an attractive solution to excess surface water problems. These drainage ditches are designed to catch rainwater, slow its discharge and promote healthy garden turf. Typical soakaways are large holes dug into the grounds of a property. During heavy rains, these drains store the water and gradually release it into the surrounding ground. They are typically constructed between five and ten metres from the property and use a permeable membrane to regulate the flow and prevent waterlogging.
The cost of a soakaway drainage system varies depending on its size, type, and location. The cost of labour can also vary depending on the region of the UK. Generally, prices are highest in the southeast, and lowest in London and northern England. In contrast, the cost of a soakaway drain system is relatively low in Scotland and Northern Ireland.
The average cost of fitting a soakaway is PS700-PS1000, depending on location. This cost includes labour, which can range from 150 to 200 per day. The whole process shouldn’t take more than a day.
Environmental impact of a Soakaway
Soakaways are drainage systems designed to improve the infiltration capacity of soils. The amount of water disposed depends on the infiltration capacity of surrounding soils and the size and bulk density of the fill material used. Soapaways can be linked together to treat large areas of runoff and recharge groundwater. They are usually the responsibility of the property owner. They also provide underground storage for stormwater.
In the United Kingdom, the most common type of infiltration device is a soakaway. These drainage systems are connected to over-sized, square or rectangular rubble-filled voids beneath lawns. However, these devices cannot be used on sites that are contaminated with sewage.
A soakaway is an area in the ground that collects runoff and removes pollutants from it. Often, a soakaway is situated on an open space, which makes it easier to maintain. It also interferes less with building foundations. However, siting requirements can vary according to local conditions and the building regulations.
Planning for a Soakaway
Planning for a Soakaway is a critical part of sustainable drainage design in new houses. Soakaways can help prevent floods, and the right design will minimise the risk of overflow. However, it’s important to ensure a successful installation by following a few simple rules.
Soakaways can prevent waterlogging in gardens and prevent damp from seeping into properties, and they can help save on water bills. However, they should be installed correctly and adhere to the Building Regulations. The Environment Agency has a set of rules for installing soakaways, and local councils can provide additional guidance.
The design of a soakaway needs to consider the type of soil on the site. The soil must have good drainage properties, otherwise the soakaway may become a pond. The location of a soakaway is also crucial, as it must be positioned at least one metre above the highest level of groundwater.
