SEWAGE TREATMENT:
Since 1984 H.D. 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.

Services Ltd is committed to completing contracts on time and use only directly employed labour.

DRILLING SERVICES:
H.D. Services Ltd. has been constructing water supply and soakaway boreholes in the South East of England since 1984. We have been members of the Well Drillers Association (WDA) since 1988 and have a vast knowledge of the hydro-geology. This means that we can generally confirm the feasibility of a proposed installation upon receipt of a site postcode.

We aim to provide the highest quality, percussion-drilled water supply borehole service available. Our clients depend on our advice and flexibility to suit their individual requirements and we in turn associate ourselves with only those suppliers that have a similar ethos. We are committed to completing contracts on time, using only directly employed labour and our own modern plant.

All drilling works associated with our renewable heating installations and sewage treatment systems are carried out in-house. An initial telephone call to our offices will result in the receipt of a budget proposal with prices for consideration at your leisure. Our engineers can visit the site, free of charge and without obligation, to assess and measure the site.
