I'm just wondering is it possible to construct a percolation area below the playing surface of a football pitch. Any examples of where this has been done would be very helpful. The Local authority here wants the percolation area to be fenced off but we just don't have the room.

Hi David,

I'm going to give as broad an answer as possible with a few options. As I deal with various LA's they all have their own slant on both the CoP and EPA Bus & Communities manual. The one thing I will say is that most of the LA's are open to workable solutions. The fact that you have an existing (I made an assumption here) football pitch means that they will surely they can find a workable solution.

At first glance I can see an issue with a gravity system. The main issue is the vent pipes that will need to be brought to GL. These can't be done in the middle of a football pitch. Also if you have more than 50m of piping assuming it is a bio unit you will need extra splitter/distribution boxes, again not ideal in the middle of a football pitch. I have not come across a situation before where the percolation area needs to be fences off. Yes for the area surrounding a wastewater treatment unit usually 7 to 8 ft but not for a percolation area. The other thing that I can see the LA zoning in on is the what load bearing weight might be applied to the percolation area. This might be why they want the area fenced off.

So Solution no.1 is to use the infiltrator leaching chambers. These have been accepted by a number of local authorities that I know of Clare/Cork/Offaly/Wexford. They system is very clever and in some ways so simple you would wonder why it never made its way over here from the US years ago. Its a semi circle chamber that replaces the need for stone and geo-textile and 4 inch pipe. Simply put it is has an open void at the bottom that lets the effluent come in contact with the soil. (I know you know this but stone does nothing to treat the effluent, just creates a void space to let the effluent down through the trench.) They can take 2.4m of soil back fill and can take tractors/cutting machinery no problem.

Solution no.2
Design a pressurised system. This will reduce your footprint and is simple to install. I am a huge fan of pressurised systems. If you are tight for space I can design a system for you that involves Zones in different areas outside the perimeter of the pitch etc. These systems can be designed with valve boxes for ease of maintenance. I installed a 450sq.m pressure system recently

I have worked on designs for GAA pitches before and the hydraulic loading was very small. If you can give me more details and percolation results and space available to you I can see if I can make a system fit.

The LA are probably concerned about seepage into field drains, but fencing will not solve this! Can u locate the perc drains outside the sidelines and avoid the drains?
