Building over or near water mains
It’s important to protect our public water mains. Please contact us at an early stage of the design process if building work is proposed near a main. Plans showing the location of our underground water mains are available on request.
Building over water mains is not permitted because they need to be accessible for maintenance and repair, and because of the structural damage that a burst water main could cause. Building alongside mains is allowed, provided certain requirements are met.
