DIAGNOSE • EXPLAIN • SOLVE
First establish what the soakaway receives.
A rainwater soakaway manages runoff from suitable roof or surface drainage. A sewage drainage field serves a different purpose and requires a different assessment. We establish which system you have before recommending repairs or replacement.
Persistent ponding can involve blocked pipes, silt, damaged connections or unsuitable ground. Investigation helps avoid replacing a soakaway when the restriction is elsewhere. Where infiltration testing is appropriate, we can include it within an agreed assessment.

A CLEAR INSTALLATION QUOTATION
Know what is included before work starts.
Assessment and testing
The existing system, proposed outlet, ground conditions and any testing or approvals that still need to be resolved.
Specified system and materials
The proposed tank, treatment equipment or rainwater drainage materials, with the basis of the selection explained.
Access and excavation
Machine access, excavation, spoil handling and any known site restrictions that affect the work.
Connections and finish
Which drains are being connected, the reinstatement included and what checks or handover information are agreed.
Every site is different. Ask us to make assumptions and exclusions clear in the quotation; an inspection or estimate does not itself confirm regulatory approval.

FREQUENTLY ASKED QUESTIONS
Useful answers before you call.
Can sewage discharge into rainwater soakaway crates?
A rainwater soakaway and sewage drainage field are different systems. Do not treat one as a substitute for the other; ask us to establish the discharge type and suitable next step.
Will a new soakaway work in every soil?
No. Infiltration and space constraints may make a proposed location unsuitable. Testing and site assessment should inform the recommendation.
Can the problem be repaired instead?
Sometimes. We investigate the accessible pipes and connections before deciding whether clearance, repair or replacement is appropriate.
