Some properties also incorporate greywater systems, which are connected to storage tanks.

If taking on work yourself, only do what you can feasibly manage within your own skillset.
You might be able to modify your gutters and drainpipes yourself, for example, as you need only fit any new pieces to the existing pieces after finding out the type of drainage system being used at your property.

You might also need to implement new junctions and inspection chambers within the drainage system. In instances such as these, you should seek expert assistance as mistakes can easily be made by people without the required expertise.
