Project Overview

This investment project - currently due to start early September 2022 - will help reduce the risk of flooding to properties in the Marchmont area of Edinburgh. It will increase the capacity of the sewer network and will benefit a number of residents who have been affected by flooding. 

The project is to be delivered by our alliance partners Caledonia Water Alliance and is expected to take around 16 months to complete

The plan is to construct the underground storm water tank within the grassed area opposite Warrender Park Terrace

What we are doing

  • The project involves installing new larger sewer pipes along sections of Marchmont Crescent and a small part of Marchmont Road, with an underground storm overflow tank which will be 20m wide by 15m deep
  • 2 Control kiosks to be installed in the grassed area next to Warrender Park Terrace.
  • During construction there will be site cabins situated next to the location of the tank on the Bruntsfield Links.

Why we are doing it

A number of properties in the area have previously been affected by sewer flooding. 

The work being done here will increase the capacity of the local waste water network and will provide extra storage during heavy rainfall.

This improvement project will help reduce the risk of flooding in the area.
