58 GROUNDWORKS; HEATING & VENTILATION SUPPLEMENT Discharge legislation is changing


The Environment Agency (EA) introduced new rules regarding the discharge of treated sewage by systems installed and in use on or after 1st


January 2015. If you


have a septic tank you need to identify whether it discharges to a river or stream (surface water discharge) or whether it discharges to a drainage field, as after 1st January 2020 discharges to surface water from both old


and new septic tanks will no longer be permitted by the EA. If your system requires replacing or upgrading due to its discharge location, you have three possible options: connect to mains sewer; install a drainage field so the septic tank can discharge to ground instead; replace your septic tank with a small sewage treatment plant. Email EA for more information.

A brand new residential development in Manchester is meeting environmental planning requirements thanks to an Ecodan system providing community heating to 105 new homes. “Following the successful installation of a Mitsubishi Electric air source heat pump system on a previous residential scheme, we recommended the Ecodan ASHP


system as we knew it would perform well, and offer a cost-efficient solution for The Aaben,” explained Dan Martell, Design Engineer, EDP. The CAHV Ecodan system boasts a capacity of 344kW and can operate at sufficiently high temperatures to provide heating and domestic hot water.
