Since 1984 HD Services has been developing sewage treatment systems culminating with the introduction of their HD-SM in 1994. Over the years we have installed hundreds of HD-SM sewage treatment systems throughout southeast England serving thousands of people.
 
Our unique modus operandi covers design, supply, installation, commissioning, and servicing. We do not employ agents to sell or install our systems and can take full responsibility for ensuring the discharge complies with the consent issued by the Environment Agency.
