Buried Tideflex valves can self clear: Llansteffan Towy Estuary

Coastal and river outfall pipes can be partially or completely buried by sand, shingle and mud. These materials can be deposited in a single tide or change with river currents so planned clearance is of little value. Tideflex all rubber check valves are an excellent alternative to flap valves for these outfall applications. 

CheckMate Valve Integral to Large CSO Outfall

In order to mitigate flooding in Glasthule Village from sewer overflows during storm events, a CSO outfall to the sea was constructed as an interim measure. A CheckMate non-return valve was identified as the best product for installation on the CSO outfall pipe to prevent backflow from the sea entering the sewer system. The low headloss of the CheckMate valve meant that a pumped solution was not necessary.

Tideflex Valves Key to Clonmel Flood Defence Scheme

*Updated and re-published 27 January 2016
Between 1995 & 2009, Clonmel Town suffered severe flooding on a regular basis from the River Suir and its tributaries. Tideflex valves made a crucial contribution to the design & construction of this important flood defence scheme, being installed where traditional flap valves posed a risk. The scheme, and the valves, performed admirably during the major floods over the 2015/2016 Christmas period, considered its first significant flood test.

Chalk up another win for Tideflex!

The chalk geology of South-East England has had a unique influence on the history and engineering of the region. The rehabilitation of Thanet district's Victorian sewer system is a complex project undertaken to prevent further groundwater contamination from sewage. MeasurIT is providing a large number of 100mm Tideflex valves to help ease the transition from the old to the new.

Shingle Beach no problem for Tideflex Valve

MeasurIT were approached to provide a solution to a recurring problem with the metal flap valve on the Strype Burn outfall and we proposed a Tideflex duckbill valve as an alternative that would be able to cope with the beach shingle.

Tideflex the answer to Woodstown Woes

This stormwater outfall on a beach near Woodstown, Co. Waterford was proving very problematic with the existing flap valve solution unable to cope with the constant shifting of beach sand. MeasurIT proposed a solution which was installed in 2014 and is operating effectively. 

Never be stuck in the mud with Tideflex

Flap valves on the stormwater discharges to the tidal section of the Parrett River at Bridgwater were constantly blocked due to mud & silt. In 2013 Wessex Water decided that Tideflex duckbill valves would provide the solution, with their proven track record in being free draining and self-clearing. We have no doubt they will be happy with their choice for decades to come.

1240mm Tideflex TF-1 In Dun Laoghaire Coal Harbour

The coal harbour at Dun Laoghaire dates from the 18th Century and the outfall of the culverted watercourse seemed a simple solution. However, the outfall was constantly experiencing blockages due to sand and rocks being swept into the outfall chamber. A Tideflex duckbill valve was proposed by MeasurIT as the most practical solution and this has been working without incident since 2006.

Tideflex Valve Array Meets IOM Challenge Head On!

This site in Douglas, Isle of Man required a robust solution to the problems of a large culvert exiting into a chamber in the sea wall which is exposed to high seas. We proposed and provided an array of 5 Tideflex check valves, which is still showing no signs of fatigue since installation in 2000.
