Project Overview

Scottish Water is investing £3 million in a major project to help reduce the risk of sewer flooding in Giffnock.

The project involves the installation of an underground storm storage tank to increase the capacity of the existing waste water network at this location.
It is being delivered by our in-house delivery team with our main contractors George Leslie Ltd and is expected to take around 12 months for completion. 

It is hoped the work will begin during the school summer holidays.

The tank will be installed beneath the grassed open space at the junction of Braidholm Road with Whitton Drive and Graffham Avenue.

What We Are Doing 

A new offline underground storage tank will be installed beneath the grassed open space on the south side of Braidholm Road next to its junction with Whitton Drive and Graffam Avenue.

This will alleviate pressure on the existing waste water network during extreme weather events by providing extra capacity for stormwater storage. The water will then be pumped back into the network when capacity allows.

Why We Are Doing It

Historically, the area has been prone to sewer flooding during times of heavy rainfall. 

This significant investment will address internal sewer flooding and the distress and upset it causes.

Once complete, the increased capacity in the new infrastructure will help reduce the risk of sewer flooding in the area and make a real difference to the households who have been affected in the past.
