A Creative Drainage Solution
We were asked to specify and quote for the installation of a land drainage system for a large garden that routinely flooded in the winter. The soil was deep, heavy clay in a flat low-lying area with nowhere to drain to. We proposed a more creative solution:
Identifying the wettest areas, we excavated a streambed and pond basin and set a raised timber deck boardwalk across it. In the winter it now fills naturally, drawing water off the surrounding surfaces. The water circulates along the stream via a submersible pump which can divert any surplus to the main drain if necessary.
We dressed the area with ‘black’ pebbles to create a simulated stream in summer when it dried out. For the planting design a palette of plants was chosen that would suit the setting with moisture loving plants close to the pond and stream bed.
High quality treated timber with a 25 year guarantee was used to ensure the decking boardwalk would be durable in this wet environment>
The wider garden area was also wet and the lawn ‘spongey’ with moss due to the bad drainage. We improved the soil, laid a new lawn complete with a serpentine stepping stone path for clean dry winter access to other parts of the garden.
This was definitely a case of working with nature rather than trying to fight it!
