We would not hesitate to recommend Marsh Industries line of separators. Excellent service with knowledgeable technical assistance for the more tricky jobs. Each quote has an exceptional level of detail and information on including all necessary spec sheets - invaluable for specialist merchants like ourselves. Highly recommended

Highly recommended!
We reccomend and sell many Marsh Industries Sewage Treatment Plants based on their quality and competitive pricing. We know that when a Marsh tank is sold we're not going to hear from that customer again....unless they want another one. Since Marsh Industries added Seperators to their range we have managed to change the spec on many orders, the quality of the tanks and expertise means that we can rest assured that our customers will be happy. With more and more development in remote and difficult to get to areas we are finding that we are selling more and more pump chambers. With our business being based on return customers we have to sell something that we can rely on. Our 'in house' engineer has always stated that the Marsh packaged pump chambers are the best to install, commission and service. Which means happy customers that return time after time for reliable products.

Ensign units
We find the Marsh Ensign units really popular with end users and installers alike - compact, reliable units with very little to go wrong. The literature is beneficial as informative but easy to understand, with Nigel always on hand to assist with any queries that may crop up. On the whole Mash are very easy to deal with which is why they're our preferred choice for wastewater tanks..

Never let us down
As an installer of Treatment Plants, we have been buying products from Marsh for many years. Staff at the point of sale are always very friendly and helpful and often supply at very short notice when required. Sometimes the products need a slight alteration, and Marsh are always willing to oblige. The product itself is always delivered when they say it will be, they haven't let us down yet over a period of many years and we have never known there to be any damage to products in any respect, neither have we ever had any problems following installation. We have enjoyed working with Marsh for many years and looking forward to doing so going forward.
