85. Connection to drainage and sewerage system

Determining whether a property is connected to mains sewerage is essential for understanding its wastewater management system.

Here is how to confirm mains sewerage connection: 

Sewerage provider 

To identify the provider responsible for the mains sewerage system, review utility documents, invoices, or contracts from relevant authorities. These documents often contain pertinent information, such as the sewerage provider's name, contact details, and customer account number. Contacting local utility agencies or visiting their official websites can also yield the required information. 

Understanding mains sewerage is crucial for ensuring hygienic waste disposal, minimising environmental impact, and maintaining community health standards. It facilitates the efficient removal and treatment of wastewater, ultimately contributing to the well-being of both individuals and the larger community. 

Foul water drainage 

Foul water drainage refers to the system of pipes and drains that collects and removes wastewater from toilets, sinks, showers, and appliances within a property. This wastewater, also known as sewage, contains human waste and other pollutants and requires treatment before it can be safely discharged into the environment. Foul water drainage systems typically connect to the public sewer network or an on-site sewage treatment facility. 

Surface water drainage 

Surface water drainage involves the management and removal of rainwater or surface runoff from roofs, driveways, and paved areas to prevent flooding and water damage. Surface water drainage systems collect rainwater through gutters, downpipes, and surface channels and direct it away from the property into drainage networks, soakaways, or natural watercourses such as rivers or streams. 

Septic tank 

A septic tank is a type of on-site sewage treatment system used in properties not connected to the public sewer network. It consists of a watertight underground tank where sewage undergoes anaerobic digestion, breaking down solid waste and separating liquids. The effluent is then discharged into a drainage field or soakaway for further treatment by soil and natural processes. 

Sewage treatment plant 

A sewage treatment plant, also known as a sewage treatment works or package treatment plant, is a facility that treats wastewater from properties or communities to remove contaminants and pollutants before discharge into the environment. Sewage treatment plants use physical, chemical, and biological processes to purify sewage and produce treated effluent that meets regulatory standards for discharge. 

Cesspool 

A cesspool, also referred to as a cesspit or soak pit, is a sealed underground tank designed to collect and temporarily store sewage and wastewater from a property. Unlike septic tanks or sewage treatment plants, cesspools do not treat or discharge effluent. Instead, they require regular emptying by vacuum tanker services to remove the accumulated waste and prevent overflow or pollution. 

Sewerage system installation and upgrades 

Information about the installation and upgrades of the sewerage system can often be found in property records, building permits, or documentation provided by the previous homeowner or local authorities. This documentation may include installation dates, permits, and details of any modifications or upgrades to the system over time. 

Last emptying date 

The last emptying or maintenance date of the sewerage system is typically recorded in maintenance records or service documents provided by the servicing company. This information indicates when the system was last pumped or emptied to remove accumulated solids and prevent blockages or overflows. 

Discharge destination

Determining whether the sewerage system discharges to the ground or surface water requires understanding the system's design and discharge points. This information may be documented in property records, planning permits, or environmental assessments. Additionally, onsite inspections or consultations with local authorities or environmental agencies can provide clarification on discharge destinations. 

Infiltration system 

An infiltration system, also known as a soakaway or drainage field, is a component of on-site sewage treatment systems designed to disperse treated effluent into the surrounding soil for further purification and absorption. It consists of perforated pipes buried in trenches filled with gravel or aggregate, allowing effluent to seep into the soil and undergo natural filtration and treatment. 

Shared system with other properties 

Determining if other properties share the sewerage system requires reviewing property records, deeds, or legal agreements that may outline shared responsibilities for maintenance and usage. Alternatively, consulting with neighbouring property owners, homeowner associations, or local authorities can provide insights into shared sewerage systems and associated arrangements.
