1. There was a survey undertaken on the houses numbers 22, 23, 24, 25, including a structure and the drainage underneath. I would like to know the results of this survey and what the advice given to the council was to rectify any issues.
Extracts from the drainage report dated 19/04/2021 for 22-25 Anson Crescent which detail the above requested information;
1: Occurrences without damage. For example, laterals, joints, etc.
NO DEFECTS WERE DETECTED
2: Constructional deficiencies or occurrences with insignificant influence to tightness, hydraulic or static pressure or pipe: Eg. wide joints, badly torched intakes, minor deformation of plastic pipes, minor erosions etc.
REHABILITATION CAN BE SCHEDULED LONG-TERM.
3: Constructional deficiencies diminishing static, hydraulic and tightness: Eg. untorched intakes, cracks, minor drainage obstructions such as calcite build ups, protruding laterals, minor damages to pipe wall, individual root penetrations, corroded pipe walls etc.
REHABILITATION IS NECESSARY MEDIUM-TERM WITHIN 3 TO 5 YEARS.
4: Constructional damages with insufficient static safety, hydraulic or tightness: Eg. axial/radial pipe bursts, pipe deformations, visually noticeable infiltration/exfiltration, cavities, in pipe-wall, severe protruding, laterals severe root penetrations, severe corrosion of pipe wall etc.
REHABILITATION PROCEDURE IS URGENT AND HAS TO BE COMPLETED WITHIN 1 TO 2 YEARS. NECESSITY FOR EMERGENCY OPERATIONS HAS TO BE EXAMINED.
5: Pipe is already or will shortly be impermeable: Eg. collapsed pipe, deeply rooted pipe or other drainage obstructions. Pipe loses water or danger of backwater in basements etc.
REHABILITATION IS URGENT AND SHORT-TERM. IN ORDER TO PREVENT FURTHER DAMAGE, NECESSARY TEMPORARY SPOT REPAIR HAS TO BE CONDUCTED ON EMERGENCY LEVEL.
