Attenuation
Natural flow patterns of the water cycle are being compromised due to the increase in development of land in urban areas, leading to both an increase in volume and flow rates, as well as having a detrimental impact on the quality of surface water runoff. Precast attenuation tanks offer a long-term whole life solution for this, as well as peace of mind.
In line with Sewers for Adoption 8 and current SuDS policies, precast attenuation tanks can be designed to suit need project needs – and come with a 100-year design life. They can be manufactured offsite under factory conditions ready for instant installation onsite, require minimum maintenance, savings on time and cost and benefits on site health and safety.
Direct Pipe Access System
An offsite manhole for large diameter concrete pipe systems that completely removes the need for a traditional manhole, any on-site benching or concrete surround.
Stop End Pipes
Precast concrete stop end pipes are normally used at the end of off-link tanks and do not include an access point. They can be manufactured with an inlet and outlet hole at any position with any diameter hole size complete with a seal.
Stop End Bend
Stop end bends consist of a 90° bend used in an up-right position as access into the pipeline and are mainly used at the downstream end depending upon the overall depth required.
Side Entry Manholes
Side entry manholes are normally used to gain mid run access entry into an in-line or off-line tank and consists of a standard concrete pipe complete with access shaft.
Mid Entry Manholes
Mid entry manholes are usually used for mid run access into either in-line or off-line tanks and consist of a standard pipe with a saddle slab and cored access hole.
Side & Mid Entry Manholes
A side or mid entry manhole complete with a bend is an economic method for accessing a tank system, eliminating the requirement for a traditional manhole and is usually used for mid access into an in-line run requiring a change of direction.
End Entry Manholes
An end entry manhole is used at the end of either an in-line or off-link tank, consisting of a standard pipe with a reinforced end wall, saddle slab pre-fitted onto the barrel complete with an access hole to suit and a 1200mm sealed manhole joint.
