![]() Subject to consent to discharge through your environment agency you may be able to discharge directly into a ditch, stream or other watercourse straight from a sewage treatment plant. ![]() ![]() ![]() At the end of the cycle the effluent is considered clean and safe to discharge into the environment.īecause the effluent is treated before discharge it gives you much more flexibility in where you can discharge it to. The bacteria breaks down the nitrates in the liquid while digesting some of the solid waste. Technology has evolved from just storing sewage, as septic tanks do, to using multiple treatment chambers and nurturing bacteria growth to produce cleaner (or less polluting) effluent.Ī treatment plant first separates solid and liquids then introduces oxygen, via an electrical component, to encourage aerobic bacteria growth within the plant. Sometimes called package treatment plants, sewage treatment plants are the preferred off-mains waste and foul water drainage systems for both property owners and environment agencies alike. You need to understand the waste and foul water requirements of your property to ensure that the system you install is capable of handling it, and you need to decide on the most suitable disposal system for your property and location. You need to be aware of the environmental impact your waste could have if not disposed of correctly. In this circumstance, the first thing you should ask is "can I treat it?". If there's absolutely no way your property can be linked to the mains system, either by gravity or pump station, then you need to install a private drainage system for your property’s waste and foul water. Foul water disposal of any kind is not something you want to get wrong. Regardless of whether the thought of working all this out makes your eye twitch, or you are a DIY master and know most of it off the top of your head, it is still highly recommended to seek expert advice during your planning stage. The approximate gallon per minute (GPM) of flow into the system.Storage capacity required for 24 hours of use without power.Overall pumping lift (vertical height between the outlet and the highest point in the discharge pipe).These are things you need to know for sizing a pumping chamber or station: Pumps need to be sized and selected specifically for your property's needs in order to reduce the risk of fat and grease build-ups, blockages, and over or under working of the pump system (both of which can severely impact the lifespan of the pump).While often minimal there is still a power requirement for pumping chambers and stations that will incur an added cost over using a gravity system.Compliance with relevant regulations will be required (BS 756-2 and Building Regulations for Foul Drainage).If the connection has to go through 3rd party land to reach the mains sewer you will need written permission from that party which will likely require some legal involvement.The installation itself could require public road works which would involve connection fees, road closures, traffic management etc.The design and installation of the system will need to be done by an expert which can be costly.You will need to apply for a "New Connection" approval from your sewage provider.There are still a number of important things you need to consider when thinking about using a sewage pump chamber or pumping station: Maintenance plans with manufacturer/installer (highly recommended).High level alarms to minimise the risk of overflowing.Wide intake pipes to minimise blockages.Automatic pumping (eliminating human contact).However, most pumping chambers are designed to keep this to minimum through the use of: You have all the benefits of your waste being taken away through a sewer system maintained by the local authority, whilst still having some of the responsibility and added cost of a private system. This option is really a midway point between mains and off-mains systems. Once this level is reached, an internal pump is activated that pressurizes the sewage and pushes it out of the wet well, through an uphill pipe system, until it either reaches the main sewer (or a point where gravity can kick in to take it the rest of the way). a pumping station).Ī pumping chamber/station consists of a large tank (called a wet well) designed to collect the sewage from the property and store it until it reaches a predetermined level. To achieve this mucky miracle you need a pump chamber (a.k.a. To transport the sewage from your property to the mains system, and avoiding the need to install a private system, you need it to defy gravity and flow uphill. In low-lying areas where the main sewer system runs higher than the foul system of a property, the normal method of gravity flow can't be utilised.
