New off-mains drainage, designed around your site
Planning a new property, development or site without a mains sewer connection? WES can take the project from initial assessment and design through specification, installation and commissioning.
A complete solution, not just a tank
A successful installation starts long before anything goes into the ground. We look at how the property or site will be used, the ground conditions, available space, access and the proposed discharge route before specifying the system.
Site & ground conditions
Space, levels, access and soil conditions all influence what can be installed and where.
Capacity & use
The system needs to suit the number of users, type of property and expected wastewater load.
Discharge & compliance
We consider the discharge route and technical requirements alongside the system itself.
The system that fits the job
There isn’t one standard answer for every off-mains site. Depending on the property, ground conditions and discharge options, the right solution may include
Sewage treatment plants
For homes, developments and commercial sites where wastewater needs to be treated before discharge.
Pump stations
Where foul water or treated effluent needs to be moved because gravity alone isn’t enough.
Septic tanks & drainage fields
A suitable option where the ground conditions, available space and discharge arrangement allow.
Cesspools
Sealed storage for sites where an appropriate discharge route isn’t available.
One team through the installation
01 Assess
We review the site, its intended use and the practical constraints.
02 Design & specify
We develop the appropriate system, discharge arrangement and technical specification.
03 Plan & install
We organise the works, equipment and site requirements and carry out the installation.
04 Commission & hand over
We complete the connections, commission the system and explain what happens next.
Ongoing servicing and maintenance can then be handled by EnviroServ.
From individual properties to complex sites
The same site-led approach applies whether we’re designing a system for a single new home or managing a larger commercial installation. For more complex work, WES can provide project management and on-site supervision as part of a complete turnkey service.
