4 Person 2600 Litre Shallow Dig Septic Tank
The 4 Person 2600 Litre Shallow Dig Septic Tank is a reliable underground wastewater solution designed for properties with up to four occupants that are not connected to the mains sewer network. Ideal for smaller homes, holiday cottages and rural properties, this high-quality polyethylene septic tank provides dependable long-term wastewater treatment while remaining straightforward to install and maintain.
Manufactured in the UK using rotationally moulded high-density polyethylene (HDPE), this septic tank features a robust ribbed construction that delivers exceptional strength without the weight of traditional concrete tanks. Its lightweight design makes transportation and installation easier, helping to reduce both installation time and associated costs.
The shallow dig design minimises excavation depth, making it particularly well suited to sites with higher groundwater levels or where reduced excavation is preferred. In many standard installations, the ribbed construction allows the use of an environmentally friendly pea gravel backfill, helping to eliminate the need for costly concrete encasement.
Supplied with a Zoeller Residential Septic Tank Effluent Filter as standard, this model provides an additional level of protection by helping to prevent solids from entering the drainage field. The filter also features a patented bypass protection sleeve, ensuring solids remain within the tank during routine filter cleaning.
Backed by a 10 Year Manufacturer’s Warranty, the 2600 Litre Shallow Dig Septic Tank offers a durable, low-maintenance wastewater solution for domestic off-mains drainage systems.
