Works involved installing attenuation tanks to an existing drainage system to provide additional storage and increase capacity for when the swimming pool filtration system is backwashed. With the GPR survey identifying electric, gas, water as well as other services in the area it was a challenge to fit the tank (designed with an 8 cubic metre capacity) in such a tight area. The project was on budget, delivered ahead of programme without damaging any existing services on site as well as minimum disruption to the club whilst our works were carried out.
