Design & Specification

Choosing the right solution for your needs is by no means simple.  WCI design solutions which are specific to your requirements.

While the selection of a septic tank or a sewage treatment plant might seem simple, every system should be specified according to the particular requirements of the property.  Like most parts of a property, the installation or repair of sewage systems, surface water systems and drainage represents a significant investment of time and money.  Once installed, the chosen system will be expected to perform every day for decades so its important to get the design and specification of the system correct.

WCI will always visit your property and invest time in understanding your requirements before specifying a solution.  We offer our design & specification services both as consulting engineers to those clients that intend on installing their own system and as design & build contractors to those people that are looking for the complete ‘cradle to grave’ solution.

If you’re in any doubt as to whether your situation requires proper design and specification, consider whether your local builders merchant or sales rep will take time to consider everything on the right!
